Abstract:

Objective: The current study was aimed at comparative quantitative phytochemical analysis of the leaves of S. italica collected from four districts in Limpopo province, South Africa, in order to establish whether geographical location have an effect on the accumulation of phytochemicals within the leaves of the plant species under study.Methods: The leaves of S. italica were collected from four districts in Limpopo province of South Africa namely; Capricorn, Sekhukhune, Vhembe and Waterberg districts, dried, ground to powder and extracted using different organic solvents. The extracts of the leaf samples from different locations were subjected to quantitative phytochemical analysis for total phenolic content, total tannin content, total flavonoid content and total saponin content using spectrophotometric measurements. The resultant quantities were analysed for statistical differences.Results: The leaf samples of S. italica from the four districts in Limpopo province showed significant differences (*p<0.05) in their phytochemical quantities, with main data expressed as mean±SD. Total phenolic content was in highest amounts in leaf samples from Waterberg district compared to samples from other districts. Total tannin content was in highest amounts in the Vhembe district leaf samples compared to samples from other districts. Total flavonoid content was in highest amounts in the leaf samples from Waterberg district compared to samples from other districts. Total saponin content was in highest amounts in the Vhembe district leaf samples compared to samples from other districts.Conclusion: The findings of the study thus suggest that geographical location has an effect on the accumulation of phytochemicals in the leaves of S. italica.

Abstract:

Background and Aim: Previous studies recorded the prevalence of gastrointestinal nematodes (GIN) in Limpopo Province. However, the studies did not address the seasonal patterns of infection and did not cover all districts of Limpopo Province, namely; Capricorn, Sekhukhune, Waterberg, Mopani, and Vhembe. It is, therefore, important to provide up to date information on the prevalence and seasonal occurrence data of GIN in all districts of Limpopo province. The present study was conducted to determine the occurrence of anthelmintic resistance (AR) and document the prevalence of GIN infecting sheep in five districts of Limpopo Province, South Africa. Materials and Methods: Forty animals in each district were used for fecal egg count reduction test (FECRT) to determine AR against ivermectin (0.2 mg/kg), levamisole (LEV) (5 mg/kg), and albendazole (7.5 mg/kg). Egg hatch test (EHT) was used to determine AR against thiabendazole (TBZ) and micro-agar larval development test (MALDT) was used for both TBZ and LEV. Naturally, infected sheep (n=780) were sampled for prevalence across five districts of Limpopo. FAMACHA© eye-color score estimations were also performed for each study animal. Results: FECRT showed occurrence of AR in most of the districts and a few with suspected resistance. EHT results showed AR development against TBZ for all districts, while the MALDT showed no AR against LEV in all districts, but detected AR against TBZ in Sekhukhune, Capricorn, and Waterberg. Haemonchus contortus was the most resistant species. A high nematode prevalence (88-100%) and 1210-1861 eggs per gram (EPG) was observed in all districts during the hot wet season, decreasing to 75-80% (453-1202 EPG) during the cold dry season. The sheep revealed a FAMACHA© mean score of 3, indicating mild anemia during the hot wet season except for Vhembe district that revealed a FAMACHA© mean score of 4 during the hot wet season, indicating anemia. Conclusion: AR recorded in Limpopo Province may be due to under-dosing caused by lack of weighing equipment and high treatment frequencies due to lack of proper training on anthelmintic use. The detection of AR in Limpopo is an important finding because it will help in outlining effective management systems against GIN.

Abstract:

Climate change is a global phenomenon that has been of great concern and its tackle is of outmost importance for food security and poverty alleviation among other things. This paper assessed the decisions informing selection of climate change adaptive strategies in Limpopo Province based on farmers’ socio-economic characteristics. Data was collected from all five districts of Limpopo province namely; Sekhukhune, Waterberg, Mopani, Capricorn and Vhembe. A questionnaire administered in a face to face interviews was used to collect data on various climate change adaptive strategies used by emerging farmers in Limpopo province of South Africa. The most identified strategies identified were crop diversification, substitution of crops, calendar redefinition, changing crop rotation patterns and fertilizer application. Results from the multinomial logistic regression model employed indicated that farmers’ socio-economic characteristics such as gender, age group, formal education, farming experience and household size significantly influenced farmers’ selection of climate change adaptive strategies. As a conclusion, farmers’ socio-economic characteristics are the major influencing factors determining selection of specific adaptive strategies. The study recommended that to enhance adaptive strategy uptake there should be a careful consideration of socio-economic characteristics that suits a need of specific farmers as farmers’ adaptation to climate change varies individually.

Abstract:

Malaria infects and kills millions of people in Africa, predominantly in hot regions where temperatures during the day and night are typically high. In South Africa, Limpopo Province is the hottest province in the country and therefore prone to malaria incidence. The districts of Vhembe, Mopani and Sekhukhune are the hottest districts in the province. Malaria cases in these districts are common and malaria is among the leading causes of illness and deaths in these districts. Factors contributing to malaria incidence in Limpopo Province have not been deeply investigated, aside from the general knowledge that the province is the hottest in South Africa. Bayesian and classical methods of estimation have been applied and compared on the effect of climatic factors on malaria incidence. Credible and confidence intervals from a negative binomial model estimated via Bayesian estimation and maximum likelihood estimation, respectively, were utilized in the comparison process. Overall assumptions underpinning each method were given. The Bayesian method appeared more robust than the classical method in analysing malaria incidence in Limpopo Province. The classical method identified rainfall and temperature during the night to be significant predictors of malaria incidence in Mopani, Vhembe and Waterberg districts. However, the Bayesian method found rainfall, normalised difference vegetation index, elevation, temperatures during the day and night to be the significant predictors of malaria incidence in Mopani, Sekhukhune and Vhembe districts of Limpopo Province. Both methods affirmed that Vhembe district is more susceptible to malaria incidence, followed by Mopani district. We recommend that the Department of Health and Malaria Control Programme of South Africa allocate more resources for malaria control, prevention and elimination to Vhembe and Mopani districts of Limpopo Province.

Abstract:

SUMMARYRabies is a prevalent and re-emerging disease in South Africa particularly in rural areas with high human densities. Outbreaks are frequently reported in the north and eastern parts of this country, probably an indication of inadequacy in the control of the disease. Following the 2005/2006 outbreak in Limpopo, we undertook an analysis of case surveillance data and genetically characterized 18 rabies viruses, all recovered from domestic dogs. Although rabies prevalence gradually declined annually from 2007, dog rabies still remains a public and veterinary health hazard in this region. Sylvatic rabies cycles are maintained by the black-backed jackal species in specific ecological conditions in the northwest of the province (Waterberg area), unlike in the north and east (Vhembe and Mopani districts, respectively), where spillover of infection between dogs and jackals is likely to predominate. Genetic analysis demonstrated that the rabies virus strain currently circulating within dog populations in Limpopo province is the same variant responsible for the 2005/2006 rabies outbreak. However, residual foci probably exist hence the observed sporadic outbreaks. These data further underline the value of continuous and sustainable dog immunization in controlling rabies.

Abstract:

This contribution aims to investigate the influence of monthly total rainfall variations on malaria transmission in the Limpopo Province. For this purpose, monthly total rainfall was interpolated from daily rainfall data from weather stations. Annual and seasonal trends, as well as cross-correlation analyses, were performed on time series of monthly total rainfall and monthly malaria cases in five districts of Limpopo Province for the period of 1998 to 2017. The time series analysis indicated that an average of 629.5 mm of rainfall was received over the period of study. The rainfall has an annual variation of about 0.46%. Rainfall amount varied within the five districts, with the northeastern part receiving more rainfall. Spearman’s correlation analysis indicated that the total monthly rainfall with one to two months lagged effect is significant in malaria transmission across all the districts. The strongest correlation was noticed in Vhembe (r = 0.54; p-value = <0.001), Mopani (r = 0.53; p-value = <0.001), Waterberg (r = 0.40; p-value =< 0.001), Capricorn (r = 0.37; p-value = <0.001) and lowest in Sekhukhune (r = 0.36; p-value = <0.001). Seasonally, the results indicated that about 68% variation in malaria cases in summer—December, January, and February (DJF)—can be explained by spring—September, October, and November (SON)—rainfall in Vhembe district. Both annual and seasonal analyses indicated that there is variation in the effect of rainfall on malaria across the districts and it is seasonally dependent. Understanding the dynamics of climatic variables annually and seasonally is essential in providing answers to malaria transmission among other factors, particularly with respect to the abrupt spikes of the disease in the province.

Abstract:

The Southern Waterberg in Limpopo Province is archaeologically rich, especially when it comes to evidence of pre-colonial mining and metal working. Geologically, the area hosts important mineral resources such as copper, tin and iron which were smelted by agriculturalists in the precolonial period. In this region however, tin seems to be the major attraction given that Rooiberg is still the only source of cassiterite in southern Africa to have provided evidence of mining before European colonization. This paper reports the results of archaeological and archaeometallurgical work which was carried out in order to reconstruct the technology of metalworking as well as the cultural interaction in the study area and beyond. The ceramic evidence shows that from the Eiland Phase (1000–1300 AD) onwards there was cross borrowing of characteristic decorative traits amongst extant groups that later on culminated in the creation of a new ceramic group known as Rooiberg. In terms of mining and metal working, XRF and SEM analyses, when coupled with optical microscopy, indicate the use of indigenous bloomery techniques that are widespread in pre-colonial southern Africa. Tin and bronze production was also represented and their production remains also pin down this metallurgy to particular sites and excludes the possibility of importing of finished tin and bronze objects into this area.

Abstract:

School leadership research has provided extensive empirical evidence which shows that women as school leaders face challenges on many fronts. The objective of this study was to provide insight regarding the challenges that female primary school principals face, in the Waterberg Education District, Limpopo Province, South Africa. These challenges were in respect of the perception of staff members towards women as school principals. This study was qualitative and interpretive in nature. The theory of social justice was used as a theoretical framework. Social justice theorists argue that social institutions have the responsibility to dispense justice, fairness, and equity. The researcher used semi-structured in-depth interviews to gain rich descriptive data on the experiences relating to the leadership roles of the principals. Findings indicate that female principals face challenges, such as insubordination by male staff members, frustrations of not progressing beyond the position of principalship and sexual harassment. This study is of great value as it extends the body of knowledge on the challenges that primary school women principals face in their leadership practices.

Abstract:

To the best of our knowledge there are presently no ethnobotanical surveys focusing on the utilisation of herbal remedies for asthma in South Africa. The present study is therefore an attempt to fill this gap in knowledge. A total of 140 Bapedi traditional healers (THs) practicing in the Capricorn, Sekhukhune, and Waterberg districts of the Limpopo Province (South Africa) were queried using semistructured questionnaires, supplemented by field observations during face-to-face interview. A total of 104 medicinal plant species (92 indigenous and 12 exotics) belonging to 92 genera, distributed across 54 botanical families, mostly the Asteraceae and Fabaceae (18.5%, for each) as well as Malvaceae (12.9%), were used as antiasthmatics and related symptoms by these THs. Most of the plants were trees and herbs (37.5%, for each), with root (57%), leaf (15.8%), and bark (7.5%), respectively, being the saliently used parts for preparation of remedies.Clerodendrum ternatum,Cryptocarya transvaalensis,Lasiosiphon caffer,Enicostema axillare,Mimusops obovata,Sclerocarya birrea, andStylochaeton natalensiswere widely used and valued by all THs across the surveyed districts. Furthermore, these taxa also scored both the highest use value and fidelity level indexes as asthma therapies. Overall, the larger number of species documented in the present study is recorded for the first time in literature as asthma and/or related symptoms remedies. Our study finding generally contributes towards an establishment of South African database of herbal therapies used traditionally against these conditions.

Abstract:

Based on rangewide sampling and three mitochondrial and two nuclear markers (together up to 1,850 bp and 1,840 bp, respectively), we examine the phylogeography of two helmeted terrapin species (Pelomedusa galeata and P. subrufa sensu stricto) and infer shifts of climatically suitable spaces since the Last Glacial Maximum using a modeling approach. Whilst P. galeata displays significant phylogeographic structuring across its range and consists of two deeply divergent lineages that could represent distinct species, P. subrufa shows no obvious phylogeographic differentiation. This seems to be related to historically stable or fluctuating ranges. One of the lineages within P. galeata appears to be confined to the westernmost, winter-rainfall region of South Africa and deserves special conservational attention due to the scarcity of surface water. The other lineage is distributed further east and is differentiated in three weakly supported subclades with parapatric distribution; one occurring inland, and two along the south and east coasts, respectively. As far as is known, P. subrufa occurs in South Africa only in the northeast of the country (Limpopo, Mpumalanga) and we report the species for the first time from the Lapalala Wilderness Area in the Waterberg region (Limpopo), approximately 350 km further west than previously recorded. We confirmed the occurrence of P. galeata only 80 km south of Lapalala. Thus, a sympatric occurrence of P. galeata and P. subrufa is possible. Another putative contact zone, for the two lineages within P. galeata, must be located in the Western Cape region, and further contact zones are likely for the eastern subclades within P. galeata. The nuclear loci provided no evidence for gene flow across taxa or genetic clusters within taxa. Future investigations should use denser sampling from putative contact zones and more nuclear markers to re-examine this situation. Despite few phylogeographic studies published for southern African biota, it seems likely that differentiation follows general rules, and that climate and physiographic barriers (e.g., the Great Escarpment) have shaped phylogeographic patterns.

Abstract:

AbstractThe historic Waterberg platinum deposit, ~15 km WNW of Mookgophong (formerly Naboomspruit), Limpopo Province, South Africa, is a rare fault-bound hydrothermal vein-type quartz-hematite-platinum-group mineralization. As a continuation of the geochemistry and ore mineralogy studies (Part I, Oberthür et al., 2018), this paper concentrates on the ore-bearing quartz and on the age constraints of ore formation. The state-of-the-art methods used include cathodoluminescence microscopy, electron probe microanalysis (EPMA) and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) of trace elements, stable isotope (δ18O) analysis and fluid-inclusion studies. U-Pb and (U-Th)/He radiometric age determination gave ages of 900–1075 Ma suggesting platinum-group element (PGE) mineralization as a result of upwelling fluids with connection to the Bushveld complex during Kibaran tectonic movements along the Thabazimbi–Murchison Lineament. Felsic fragments containing Qtz-1 were cemented by different quartz generations (Qtz-2 to Qtz-4) and enable the characterization of the changing physicochemical parameters during multistage mineralization and cooling. The PGE minerals are associated with the earliest hydrothermal stage represented by botryoidal radial-fibrous quartz aggregates (Qtz-2a) which formed on brecciated felsite. The other quartz types are essentially barren. Cathodoluminescence studies of quartz indicate very high Al, Fe and K concentrations as confirmed by EPMA and LA-ICP-MS, whereas Ti is always very low. The varying Al concentrations in the quartz mainly indicate pH fluctuations, the high Fe3+ points at high oxygen fugacity. Micro-inclusions of iron oxide are associated with Pt ore (Fe, Pt, Pd, Au, W, Sb, As), rutile, kaolinite and muscovite. The hydrothermal activity must have been characterized by low saline (<10 wt%) H2O–NaCl solutions. These fluids mixed with original high-saline NaCl ± CaCl2 ± CO2 brines in the brecciated felsite (Qtz-1). According to the quartz-hematite geothermometer the ore depositional temperatures were ~370–330°C (Qtz-2a), whereas the successive quartz veins formed during cooling towards ~295°C. The transport of PGE must have been facilitated by strongly oxidizing chloride complexes of relatively low salinity and moderate acidity.

Abstract:

Geothermal springs are natural geological phenomena that occur throughout the world. South Africa is blessed with several springs of this nature. Limpopo province contains 31% of all geothermal springs in the country. The springs are classified according to the residing mountain: Soutpansberg, Waterberg and Drakensberg. This study focused on the geothermal springs within the Soutpansberg region; that is, Mphephu, Siloam, Sagole and Tshipise. The study was aimed at assessing the occurrence and potential health risk associated with drinking water from geothermal springs within Soutpansberg. Geothermal springs and boreholes were sampled for a period of 12 months (May 2017–May 2018) to accommodate two major seasons in the study areas. The physicochemical and trace metal compositions of the geothermal springs and boreholes (tepid and hot) were analyzed using ion chromatography (IC) (Dionex Model DX 500) and inductively coupled plasma-mass spectrometer (ICP-MS). Trace metal concentrations of the geothermal springs and boreholes were within permissible drinking water guidelines by the South African National Standards (SANS) and World Health Organisation (WHO), with exception of mercury (Hg), which is high in summer season. The bioaccumulation from regular consumption could, however, result in negative effects. Pearson’s correlation revealed that there is a direct relationship between temperature and pH, and some of the trace metals (V, Zn, Hg, Pb). This implies dissolution of minerals (rock-water interaction) under slightly high temperature. Multivariate statistics further elucidate the relationship and possible sources of the trace metals. Therefore, it can be inferred that the rock-water interaction is the main geochemical process governing the release of trace metals in groundwater. Hazard Index values for both children and adults were higher than 1, and this implies that the communities are at high risk of non-cancer health effects. Further, As, Cr and Cd were found to be the highest contributors to the potential cancer risk in the study areas, with children having a higher risk than adults. Therefore, there is a need for clinical/epidemiological study, and regular monitoring and control measures, to verify actual prevalence of cancer and protect human health, particularly the children, within the study areas.

ABSTRACTThis study provides the first detailed mineralogical data on platinum-group element (PGE) mineralization of the Waterberg Project, in a previously unknown segment of the Bushveld Complex located in the Southern Marginal Zone of the Limpopo Belt. The lower ultramafic F zone is dominated by sperrylite (up to 82 area%) with minor Pt–Pd bismuthotellurides, Pd–Ni arsenides, Au–Ag alloy, Rh–Pt sulfoarsenides and rare Pt–Fe alloys. The upper more felsic-rich gabbroic T zone is dominated by Pt–Pd bismuthotellurides (up to 90 area%), Pd tellurides and Au–Ag alloy with rare sperrylite, braggite, Pd stannides and antimonides. The platinum-group minerals (PGM) of the F zone are associated mainly with magmatic base-metal sulfides (pyrrhotite, troilite, chalcopyrite and pentlandite), that have undergone alteration during significant serpentinization, accompanied by the formation of the secondary sulfide assemblage. The T zone in a leucogabbroic sequence contains relics of magmatic sulfides and is characterized by the development of the indicative chalcopyrite-millerite-pyrite assemblage, which is associated with widespread hydrothermal quartz and hydrous silicates (amphiboles, phlogopite, epidote and chlorite). The fluid-induced style of PGM remobilization, the high Au/PGE and the high proportion of native gold in the high-grade T zone ores in the magnetite-bearing leucogabbroic rocks are unique to the Bushveld Complex. The genesis of the T ores is interpreted as a result of primary PGE enrichment in the zone of interaction between the first influxes of the Upper Zone fertile melt and a resident gabbroic melt at the top of the Troctolite-Gabbronorite-Anorthosite (TGA) fractionated sequence with subsequent fluid remobilization. Whether the hydrothermal overprint facilitated the PGE sequestration in a favourable setting or dispersed the pre-existing magmatic concentrations along fluid pathways remains essentially unresolved at the current stage.

Abstract:

Despite the large number of collection records, there are no recent collections of ixodid ticks of this magnitude in the Waterberg area, Limpopo Province, South Africa. Free-living ticks on a commercial game farm were obtained by a total of 432 drag-samples in eight sample sites from September 2003 to August 2008. The ticks were collected to establish the difference between tick species and densities associated with acaricide-controlled (semi-intensive) and control-free areas on a game farm in the Thabazimbi District, Limpopo Province, South Africa. A total of eight tick species were collected, namely Amblyomma hebraeum, Rhipicephalus (Boophilus) decoloratus, Haemaphysalis elliptica, Hyalomma rufipes, Rhipicephalus appendiculatus, Rhipicephalus evertsi evertsi, Rhipicephalus zambeziensis and Rhipicephalus spp. The most abundant tick species collected was Rhipicephalus (Boophilus) decoloratus. The difference in species and numbers reflects the effectiveness of acaricide treatment against ticks and its relevance to tick numbers on a game farm.

Abstract:

Community projects aimed at alleviating poverty under the supervision of social workers employed by the Department of Social Development (DSD) in the Waterberg district of the Limpopo Province seem to be collapsing. This prompted the researchers to undertake a qualitative study using a contextual, descriptive and explorative research design aimed at obtaining an in-depth understanding of the monitoring and evaluation (M&E) mechanisms applied in supporting community projects for alleviating poverty. This article reports on findings based on interviews conducted with 21 participants. The study identified a lack of knowledge and training, as well as poor management and supervisor support as contributors towards weak M&E.

Abstract:

Background: The shortage and unequal distribution of medical doctors in low- and middle-income countries continues to be a public health concern.Objective: To establish the geographical distribution and demographic profile of medical doctors in public sector hospitals of the Limpopo Province, South Africa.Method: The PERSAL system was used to obtain information on the number of medical doctors employed in public sector hospitals of the Limpopo Province. Data were exported from PERSAL’s database and then analysed using STATA version 9.0.Result: The mean age of the 887 medical doctors was 40.1 ± 11.2 years (range 24–79 years). Sixty per cent of the doctors were male, 66% were aged ≤ 45 years and 84% were African. Most of the doctors (86%) were medical officers, of which 55% had < 5 years working experience. Overall, the doctor-to-population ratio for the five districts in the province was 16.4/100 000, with Capricorn (33.7/100 000) and Waterberg (20.2/100 000) recording the highest ratios. A large proportion (43%) of medical officers are employed in the Capricorn District, of which 71% were practising at the tertiary hospital.Conclusion: This study demonstrated a shortage and maldistribution of medical doctors in the public sector hospitals of the Limpopo Province. This has a potentially negative effect on the delivery of an appropriate and efficient healthcare service to the population and requires urgent attention.

Abstract:

This study investigates the manner in which the implementation of the National School Nutrition Programme (NSNP) is managed by the principals in under-resourced primary schools in the Waterberg district of Limpopo province, and as such forms part of a larger joint UP and NENU study of the state of the principalship in both urban and rural settings in the two countries. Data for this qualitative study was collected within the framework of the four management functions described by Van Deventer and Kruger: planning, organising, leading and directing, as well as controlling and evaluating, by interviewing and observation. The study’s primary finding is that, although principals are aware of the guidelines and practices for the implementation of the NSNP, prescribed by the Department of Basic Education, they rely almost entirely on other role player at school level to manage the programme, without any day-to-day involvement in the process or any recognition of their own roles and responsibilities in this regard.

Abstract. Rasethe MT, Potgieter M, Pfab M. 2021. Local management strategies and attitudes towards selected threatened or protected plant species in Limpopo Province, South Africa. Biodiversitas 22: 3773-3784. Throughout South Africa, ordinary people are managing and using local natural resources in ways that enhance their lives, but there is a major concern about the sustainability of wild plant harvest. This study aims to investigate the current management strategies employed by local people in the Limpopo Province for selected threatened or protected plant species (TOPS). Semi-structured questionnaires were used to gather information from a total of 333 participants, i.e. 110 community members (CMs), 180 traditional health practitioners (THPs), and 28 traditional leaders (TLs), as well as from 15 conservation officers (COs). The study area included the districts of Capricorn, Sekhukhune, Mopani, Vhembe, and Waterberg. Results indicated that in all districts of the province most CMs and THPs reported that no one managed plant resources in their surrounding communal lands, though TLs indicated that the state was involved with management. Fifty-nine percent of THPs indicated that there are no traditional rules that are applied towards conservation of communal lands, yet 91% of other participants in the Mopani, Sekhukhune, and Capricorn districts indicated that traditional rules are followed. Most CMs in these three districts were allowed to participate in conservation initiatives, although most of them did not know that the plants they were using were threatened and protected in legislation. It is recommended that collaborative partnerships be initiated between government and TLs in relation to managing the threatened or protected plant species in communal lands.

Abstract:

Background: There are many gaps in the management of diabetes mellitus (DM) and diabetic eye disease in the district health system (DHS) of South Africa (SA). National guidelines recommend annual eye examinations for patients with DM.Aim: The purpose of this study was to describe the self-reported skill levels of healthcare practitioners (HCPs) to conduct eye examination procedures required for a proposed diabetic retinopathy (DR) screening model.Setting: The study was conducted in public health institutions of Waterberg district and Mankweng Hospital complex (Capricorn district) in Limpopo province, SA.Methods: A cross-sectional design using purposive sampling was conducted, and questionnaires were distributed to a total of 74 HCPs. The questionnaires distributed included questions relating to the competency levels of primary healthcare nurses (PHC nurses), optometrists, ophthalmic nurses and medical officers (MOs) regarding examination procedures in the management of patients with DM and whether they agreed with the developed DR screening model.Results: All the PHC nurses had knowledge about all the examination procedures required in the proposed DR screening model, whilst 94.1% of MOs exhibited knowledge regarding the procedures required from them. Optometrists lacked knowledge of grading DR, and ophthalmic nurses were least knowledgeable about conducting internal and external eye examinations and in detecting and grading DR.Conclusion: The proposed DR screening model did not need modification. The involvement of dieticians and more ophthalmic nurses could be beneficial to the DR screening model.
