Abstract:
Banana bunchy top virus (BBTV; genus Babuvirus, family Nanoviridae) is a serious pathogen of banana (AAA genome) and plantain (AAB genome) (Musa sp.). It is transmitted by the banana aphid (Pentalonia nigronervosa) in a persistent manner (1). In recent years, BBTV has emerged as a major constraint to banana and plantain production in several countries of Africa and had been previously confirmed in viz., Burundi, Central African Republic, Republic of Congo, Democratic Republic of Congo, Egypt, Equatorial Guinea, Gabon, Malawi, and Rwanda (1) and more recently in Mozambique and Zambia (2) and Angola (3). To assess the potential threat of BBTV in West-Central Africa, we conducted surveys in August and September 2008 in 36 major banana- and plantain-producing regions of Littoral, South, Southwest, and Western Provinces of Cameroon. DNA was extracted from 520 plants and tested by PCR with primers specific for a conserved domain of BBTV DNA-R segment (4). A 240-bp DNA fragment specific to the virus was amplified in 31 samples from 18 plantain and 13 banana plants from Southwest, Western, and Southern Cameroon. Among virus-positive samples, symptoms (upright leaf growth, small leaves with pale chlorotic margins that choked the throat of the plant creating the bunchy appearance at the top) typical of bunchy top disease were observed only in banana (cv. Cavendish Williams) from Muea in the Southwest Province. PCR products obtained from the symptomatic and asymptomatic banana (Cavendish Williams) from Muea and Abang, respectively, were cloned into pCR2.1 (Invitrogen, Carlsbad, CA) and two independent clones from each isolate were sequenced in both directions. Pairwise comparison of these sequences showed 100% sequence homology. A comparison of these sequences (Accession No. F580970) with corresponding sequences in GenBank showed 99% nt sequence identity with a BBTV isolate from Angola (Accession No. EU851977) and 96 to 98% identity with BBTV isolates belonging to the South Pacific group (Australia, Africa, South Asia, and South Pacific). However, the BBTV isolate from Cameroon showed 85 to 90% sequence identity with isolates belonging to the Asian group (China, Indonesia, Japan, Taiwan, Philippines, and Vietnam). To further confirm the virus identity, complete nucleotide sequence of the DNA-SCP segment that encodes for the virus coat protein was determined using PCR amplification of viral DNA (1), cloning of products into pCR2.1 vector, and sequencing. The derived sequence (1,075 nt; Accession No. GQ249344) in BLAST search at NCBI database revealed 98% nt sequence identity with coat protein gene of BBTV isolate from Burundi (Accession No. AF148943). These results, together with phylogenetic analysis, indicate that BBTV isolates from Cameroon have greater affinity to the South Pacific group. To our knowledge, this is the first report of BBTV in West-Central Africa. The occurrence of BBTV in the Western and Southern provinces of Cameroon, neighboring north of Gabon, suggests a possible spread of the virus from Gabon. This report also underscores the need to monitor other countries of West Africa for BBTV and enforce quarantine measures to prevent further spread through infected suckers from endemic areas of West and Central Africa.

Abstract:
AbstractThe aim of this study was to test the hypothesis of the presence of hybrids between Schistosoma guineensis and S. haematobium in the Estuaire province (Western Gabon). Egg morphometry and single-stranded conformational polymorphism (SSCP) analysis on adult worms were used in order to characterize the schistosome populations of two sites. The morphology of the eggs showed three morphotypes: S. haematobium, S. guineensis and intermediate morphotypes, but the eggs of the morphotype S. guineensis were smaller compared to the values found in the literature. Furthermore, the SSCP analysis of the adult schistosomes showed that all the patterns corresponded to that of S. haematobium and gave evidence that hybrids were absent from our samples.

Abstract:
Developing and enhancing strategies to characterize actual forests structure is a timely challenge, particularly for tropical forests. P-band synthetic aperture radar (SAR) tomography (TomoSAR) has previously been demonstrated as a powerful tool for characterizing the 3-D vertical structure of tropical forests, and its capability and potential to retrieve tropical forest structure has been discussed and assessed. On the other hand, the abilities of L-band TomoSAR are still in the early stages of development. Here, we aim to provide a better understanding of L-band TomoSAR capabilities for retrieving the 3-D structure of tropical forests and estimating the top height in dense forests. We carried out tomographic analysis using L-band UAVSAR data from the AfriSAR campaign conducted over Gabon Lopé Park in February 2016. First, it was found that L-band TomoSAR was able to penetrate into and through the canopy down to the ground, and thus the canopy and ground layers were detected correctly. The resulting TomoSAR vertical profiles were validated with a digital terrain model and canopy height model extracted from small-footprint Lidar (SFL) data. Second, there was a strong correlation between the L-band Capon beam forming profile in HH and HV polarizations with Land Vegetation Ice Sensor (LVIS) Level 1B waveform Lidar over different kinds of forest in Gabon Lopé National Park. Finally, forest top height from the L-band data was estimated and validated with SFL data, resulting in a root mean square error of 3 m and coefficient of determination of 0.92. The results demonstrate that L-band TomoSAR is capable of characterizing 3-D structure of tropical forests.

Abstract:
Human herpesvirus 8 (HHV-8) is the etiological agent of all forms of Kaposi’s sarcoma (KS). K1 gene studies have identified five major molecular genotypes with geographical clustering. This study described the epidemiology of HHV-8 and its molecular diversity in Gabon among Bantu and Pygmy adult rural populations and KS patients. Plasma antibodies against latency-associated nuclear antigens (LANA) were searched by indirect immunofluorescence. Buffy coat DNA samples were subjected to polymerase chain reaction (PCR) to obtain a K1 gene fragment. We studied 1020 persons; 91% were Bantus and 9% Pygmies. HHV-8 seroprevalence was 48.3% and 36.5% at the 1:40 and 1:160 dilution thresholds, respectively, although the seroprevalence of HHV-8 is probably higher in Gabon. These seroprevalences did not differ by sex, age, ethnicity or province. The detection rate of HHV-8 K1 sequence was 2.6% by PCR. Most of the 31 HHV-8 strains belonged to the B genotype (24), while the remaining clustered within the A5 subgroup (6) and one belonged to the F genotype. Additionally, we reviewed the K1 molecular diversity of published HHV-8 strains in Africa. This study demonstrated a high seroprevalence of HHV-8 in rural adult populations in Gabon and the presence of genetically diverse strains with B, A and also F genotypes.

Abstract:
Human African Trypanosomiasis (HAT) is an infectious disease due to a protozoa parasite of the Trypanosoma genus. In West and Central Africa, this disease is caused by the subspecies Trypanosoma brucei gambiense. Several foci of this disease are currently active and causing the death of hundreds of people in endemic areas. In this article, we report two cases of gambiense HAT in one Indonesian and one Gabonese men in two historical foci of Gabon in 2019. Both patients had fever with temperatures above 38°C, an altered state of consciousness, cachexia, and multiple dermabrasions on the abdomen related to scratching lesions. The diagnostic revealed second-stage infection of both patients with T. b. gambiense; this result was confirmed by a polymerase chain reaction assay. Despite treatment with a combination of eflornithine and nifurtimox, as recommended by the World Health Organization for late-stage T. b. gambiense HAT, one of the two patients died. Thus, these cases highlight the importance of early HAT diagnosis and prompt patient care to fight effectively against this disease.

Abstract:
A new species of the freshwater crab genus Potamonautes MacLeay, 1838, is described from Ivindo National Park in Sofala Province, Gabon, Central Africa. Potamonautes nheenae n. sp. is morphologically distinct from the other species of this genus found in Gabon and nearby countries in Central Africa, and is most closely related to P. paecilei (A. Milne-Edwards, 1886) from the Lower Congo River basin in the Democratic Republic of the Congo. The new species is recognised by a unique combination of morphological characters of the adult male first gonopod, anterior sternum, mouthparts, and major cheliped. Illustrations of P. nheenae n. sp. are provided and differences with congeners found in Central Africa are discussed. In addition, the male gonopods, pleon, and sternum of the unusual freshwater crab Erimetopus brazzae (A. Milne-Edwards, 1886), are illustrated for the first time since its description in 1886, following the discovery of the first known male specimen of this species in the collection of the Museum of Comparative Zoology at Harvard University.

Abstract:
In Gabon, the situation of Human African Trypanosomosis (HAT) remains unclear. In addition, several historical foci existing in many provinces have not been explored for over 15 years. Yet many studies have shown that this country has to offer favorable ecosystems for the development of tsetse major vectors of HAT. To verify a risk of transmission of sleeping sickness, a tsetse inventory was conducted in the province of Ogooué Ivindo historic home of HAT. Vavoua and Nzi traps were placed in four characteristic habitats of the province: National Park Ivindo, Zadié Village, Forest of Zadié and baï (clearing) of Momba. A total of 2383 flies were captured: 1680 flies in the clearing of Momba, 437 flies in the primary forest Zadié, 139 in the National Park Ivindo and 12 in Zadié village. Moreover, these flies were divided into 7 species Glossina frezili, Glossina fusca congolensis, Glossina nashi, Glossina palpalis palpalis, Glossina tabaniformis, Glossina fuscipes fuscipes and Glossina tachinoides. Glossina palpalis palpalis (46%) was the most abundant species followed by Glossina fusca congolensis (21%) and Glossina nashi (16%). Glossina fuscipes fuscipes (6%), Glossina frezili (4%), Glossina tabaniformis (4%) and Glossina tachinoides (3%) were the least caught species. These results have shown that the province of Ogooué Ivindo still remains infested by tsetse flies. Also, further study monitoring these insects is essential to clarify the epidemiological importance of these vectors on human health in this province.

Abstract:
Background and Aim: Gastrointestinal infestations caused by intestinal parasites are the most important diseases and the most common in pigs in the tropics. These parasites are often associated with a huge economic loss. This study aimed to assess the diversity and prevalence of gastrointestinal parasites in farmed pigs from Haut-Ogooue Province, in South East Gabon. Materials and Methods: From March 2018 to July 2018, 156 samples of pig feces collected from nine different farms were analyzed under light microscopy. The identification of eggs, cysts, and oocysts in fecal samples was done using two qualitative techniques: Flotation and sedimentation. Results: After examination, the results obtained revealed an overall infestation level of 98.7% (154/156). We found ten parasite types with infestation levels that varied from species: Balantidium coli (120/156), Oesophagostomum spp. (100/156), Isospora suis (102/156), Ancylostoma spp. (17/156), Trichostrongylus spp. (28/156), Hyostrongylus spp. (13/156), Strongyloides spp. (7/156), Ascaris suum (8/156), Globocephalus spp. (1/156), and spirurida (1/156). The study of risk factors revealed that factors such as sex, age, and physiological condition may influence the diversity and level of infestation of animals by gastrointestinal parasites. Conclusion: For better prevention of parasitism in these farms, it would be interesting to implement health monitoring and to ensure good hygiene. Finally, further studies would be needed to better evaluate the distribution of these parasites in Gabon and the involvement of these animals in the transmission cycle of parasitic zoonoses.

Abstract:
During a disease inspection at the sugarcane estate SUCAF near Franceville, Gabon, in March 2011, 1- to 3-mm wide and several dm long dark red stripes were observed on sugarcane (Saccharum spp.) leaves of many plants of cultivar R570. These plants were 5.5 months old in the first ratoon crop. Additionally, spindle leaves of several stalks were rotted and could be easily pulled out of the top of the stalk. Longitudinal sections of diseased stalks showed reddish-brown discoloration of the upper stem and the rotted spindle had an unpleasant odor. Circular, convex, smooth, yellow-cream pigmented bacterial colonies with 2 to 3 mm diameter were isolated after 3 days at 28°C from young leaf lesions on YPGA (yeast extract 7 g/L, peptone 7 g/L, glucose 7 g/L, agar 15 g/L, pH 6.8 to 7.0). The 16S-23S internal transcribed spacer (ITS) of two representative colonies was PCR amplified, and the nucleotide sequences were shown to be 99% identical to the 16S-23S ITS sequence from the genome of Acidovorax avenae subsp. avenae strain ATCC 19860 (GenBank: CP002521.1). One of these A. avenae subsp. avenae isolates from Gabon was inoculated into greenhouse grown plants of sugarcane cultivar R570. Plants were inoculated by injection into the sheath of spindle leaves above the meristem with the bacterial strain (12 plants) or with a water control (six plants). In this method, the bacteria (108 CFU/ml) were injected using a syringe through the leaf sheath until filling the leaf whorl. Three weeks post-inoculation, one to several cm long red-brown stripes were observed on leaves of 11 of 12 inoculated plants. Seven weeks post-inoculation, all plants exhibited symptoms, from red, brown, or black stripes to leaf necrosis, rotting, and death of the spindle leaves (six plants). All six control plants were symptomless. In a second experiment, 6 of 12 plants showed symptoms 3 weeks post inoculation, and the pathogen was successfully re-isolated from all six symptomatic plants with YPGA medium. The 16S-23S ITS of three single colonies obtained each from different symptomatic plants were PCR amplified and the nucleotide sequences were again found 99% identical to the 16S-23S ITS sequence from the genome of A. avenae subsp. avenae ATCC 19860. To our knowledge, this is the first report of A. avenae subsp. avenae, the causal agent of sugarcane red stripe (also reported as top rot), in Gabon. It is also the first description of the occurrence of the top rot form of the disease in R570, a cultivar that is grown in several locations of Africa, the Mascarene Islands, and the French West Indies. A large-scale survey needs to be undertaken to determine the distribution of red stripe in Gabon, a disease for which several outbreaks have been reported recently worldwide (1,2). References: (1) M.

Abstract:
BackgroundLoiasis is a parasitic infection highly endemic in West and Central Africa. Previously often considered as a benign infection, recent studies have suggested that high microfilaria loads in loiasis patients may be associated with increased mortality. The true impact of loiasis on affected communities is unknown. Reports on clinical symptoms and changes in laboratory values due to loiasis infection are focused mostly on returning travellers. Assessments in endemic populations have scarcely been performed. Laboratory alterations such as eosinophilia are thought to be present mostly in patients from non-endemic areas.MethodsThis cross-sectional study was performed in rural Gabon to investigate the clinical symptoms and laboratory changes caused by loiasis in an endemic population. Inclusion criteria were local residency for at least two years and an age above two years. Participants were interviewed with a questionnaire covering loiasis-specific symptoms, exploratory questions and history of eye worm. Local vocabulary was employed if needed. At the same time L. loa microfilaria diagnostics were performed including thick blood smear preparation and concentration techniques. Additionally, differential blood count and haemoglobin measurements were performed. Peripheral blood withdrawals were done between 10 am and 3 pm.ResultsA total of 1030 participants were recruited, of whom 56% were female; they were between 2 and 98 years of age. L. loa microfilariae were detectable in 27% of all participants. Microfilariae densities ranged from 1 to 76 250 Mf/mL. Overall a positive history of eye worm was reported in 56%, with 25% of participants reporting eye worm passage and 36% Calabar swelling within the last year. Also, an analysis of laboratory parameters in comparison to clinical data and infection status was performed.ConclusionLoiasis infection should receive more attention by the scientific community and further studies are needed, as the disease causes substantial morbidity in endemic populations.

Abstract:
Mango (Mangifera L.) is a horticulture crop that grows in tropical regionthat has high diversity in Bengkulu Province. However, its diversity in this province has not been revealed, whereas on the other hand mango diversity is currently endangered due to the conversion of forests from natural habitat to plantation and industry. This study was aimed to determine the mango diversity in Bengkulu using morphological characters. All of the speciemens were collected from the field using exploration method that conducted from September 2016 to March 2017. A total of 17 individuals of mango were examined, and classified into seven mango species. The examination was conducted on the morphological characters, these characters were then scored and analyzed using NTSYSpc 2.02. The coefficient of similarity of 17 mango trees ranges from 0.45 to 0.80. Dendrogram showed that the clustering of mango was not based on the origin of the population but based on the morphological characters. The first group comprises six individuals and the second group consists of 11 individuals

Abstract:
Gembili (Dioscorea esculenta L.) is a tuber of the type (clan) Dioscorea as a 27 - 37% carbohydrate producer and has a nutritional composition that varies according to species. The research was conducted from May to December 2019 in Tanimbar Island Regency, Maluku. Using the method of observation and description. The morphological character of the five local accessions showed that the characters of the same plant species were singular and striking, namely the presence of roots on the tuber surface and the location of the roots on the tuber surface. There were spines on the tuber surface, and the weight of the tubers of the five accessions averaged 1.71-2, 72 kg higher than the highest collection at the Genetic Research and Development Center for Agricultural Biotechnology and Genetic Resources, namely accessions R 506 (Lokal Tanatoraja) and R 601 (Lokal Manukan) which only weighed 1,000 g. The five accessions of the Gembili plant have the potential to be developed as an alternative food.

Abstract:
The male is described by the first time for Lasiotheus Paclt, 1963 (Nicoletiidae: Atelurinae) upon a sample of L. nanus (Escherich, 1903) obtained in Gabon, from where the genus was previously unknown. The real independence of Lasiotheus relatively to Gastrotheus Casey, 1890 s.s. and to Pseudogastrotheus Mendes, 2003 (all previously considered under Gastrotheus Casey, 1890) is reinforced. Five tribes are recognized in Nicoletiidae (Atelurinae), characterized on morphological characteristics shared by groups of genera: Atelurini Remington, 1954, Atopatelurini n. tribe, Dinatelurini n. tribe, Dionychellini n. tribe and Grassiellini n. tribe. Identification keys are proposed to the ca. 70 genera today known in the subfamily.

A total of 1362 samples were investigated included 647 clinical samples and 715 from food. This study investigated the differences in the seasonal occurrence of L. monocytogenes in Kurdistan region-Iraq. L. monocytogeneswas found in 48 samples (3.52%) out of 1362 samples. There were 7/642(1.09%) human clinical samples diagnosed with cold and moderate weather (November, December 2016, and January, February, April 2017). While 41/715(5.73%) of L. monocytogenesisolates were found among food samples, meat samples (n=37) and dairy samples (n=4). A total of 37/476 (7.77%) of the L. monocytogenes isolates in meat samplesweredetected during warm weather (from July through October 2016). In addition, L. monocytogenesin dairy products was found to be by 4/239 (1.68%), were isolated during the moderate season (October, November 2016, and April, May 2017). The study found that the incidence of meat contamination by L. monocytogenesincrease significantly during the warm season in comparison with other seasons. Furthermore, the cases of human Listeriosis caused correlated well with the seasonal levels of L. monocytogenesfound in dairy products. A statistically significant difference in the occurrence of L. monocytogenesisolates and seasons were identified in this study (P value= <0.05).

Therefore, a study of crop wild relatives (CWR) in Kaliningrad Province appears vital to identify the most vulnerable species and enhance their in situ conservation.Materials and methods. Crop wild relatives occurring in Kaliningrad Province were the research target. The WIR and LE herbarium collections, published data, and results of VIR’s plant explorations undertaken in 1974 and 1983 served as the material for the research. Plant species included in the Red Data Books of Kaliningrad Province, Lithuania, Estonia, Poland, etc. were analyzed, and the data from open databases (GBIF, CWR, ILDIS, etc.) and AgroAtlas maps were employed. CWR requiring special conservation measures were identified.Results and conclusions. Kaliningrad Province, Russia, is home to 324 species of CWR. Natural habitats of the 6 most vulnerable plant species were mapped: Vicia dumetorum L., Trifolium rubens L., Chrisaspis spadiceum L., Elytrigia juncea (L.) Nevski, Phleum phleoides (L.) H. Karst., and Allium vineale L. These species fall under the 1st vulnerability category.
