Abstract:
This article is the summary of a workshop, which took place in November 2013, on the roles of microorganisms in chronic respiratory diseases. Until recently, it was assumed that lower airways were sterile in healthy individuals. However, it has long been acknowledged that microorganisms could be identified in distal airway secretions from patients with various respiratory diseases, including cystic fibrosis (CF) and non-CF bronchiectasis, chronic obstructive pulmonary disease, asthma and other chronic airway diseases (e.g.post-transplantation bronchiolitis obliterans). These microorganisms were sometimes considered as infectious agents that triggered host immune responses and contributed to disease onset and/or progression; alternatively, microorganisms were often considered as colonisers, which were considered unlikely to play roles in disease pathophysiology. These concepts were developed at a time when the identification of microorganisms relied on culture-based methods. Importantly, the majority of microorganisms cannot be cultured using conventional methods, and the use of novel culture-independent methods that rely on the identification of microorganism genomes has revealed that healthy distal airways display a complex flora called the airway microbiota. The present article reviews some aspects of current literature on host–microbe (mostly bacteria and viruses) interactions in healthy and diseased airways, with a special focus on distal airways.

Abstract:
Abstract More than 300 years ago, Antony van Leewenhoeck first described observing single-celled microorganisms, which he termed “animalcules,” examining his saliva under a microscope. Although the idea of the coexistence of microorganisms in our body is not new, we have only recently been able to investigate their ecological relationship to our body, with the development of high-throughput molecular techniques. The diverse microorganism communities residing in our guts are established and maintained by complex interactions among microorganisms and their host. Notably, their alteration has been implicated in influencing various diseases including neurological diseases. Alzheimer’s disease (AD) is the most common cause of dementia characterized by a progressive decline in memory and thinking severe enough to interfere with daily life. Despite the great progress in linking genetic risk factors with AD pathogenesis, treatments targeted at AD pathology and its modifiers have not yet resulted in a disease-modifying therapy. There is mounting evidence that the gut microbiota interacts with AD pathogenesis by disrupting neuroinflammation and metabolic homeostasis—the gut microbiota has gone from being the forgotten organ to a potential key player in the AD pathology.

Abstract:
Objective: Miltefosine is an anti-cancer drug used to treat leishmaniasis and deadly opportunistic free-living amoeba and other deadly pathogenic microorganisms. Several studies have demonstrated its antiviral effect. In this study, we discuss the effectiveness of this drug on pathogenic microorganisms, and according to the functional system of the medicine, we present this drug as a therapeutic proposal to treat Coronavirus disease (COVID-19) Methods: A literature search was conducted in electronic databases, including Pubmed, Science Direct, Elsevier, and Google Scholar, and articles published from 2006 to 2020 (the last decade) were selected. The search keywords included Miltefosine, microorganism, pathogen, and treatment. Results: The studies indicated that Miltefosine had therapeutic effects on leishmaniasis and deadly opportunistic free-living amoeba and other deadly pathogenic microorganisms. Several studies have proven its antiviral effect. Conclusion: Owing to the beneficial effects of this drug on pathogenic and deadly microorganisms and antiviral effects, and due to the epidemic of Coronavirus and the lack of effective treatment and vaccine, this drug is recommended as one of the treatment options for this disease.

Abstract:
Microorganisms in the human body play a vital role in metabolism, immune defense, nutrient absorption, cancer control, and prevention of pathogen colonization. More and more biological and clinical studies have shown that the imbalance of microbial communities is closely related to the occurrence and development of various complex human diseases. Finding potential microbial-disease associations is critical for understanding the pathology of a few diseases and thus further improving disease diagnosis and prognosis. In this study, we proposed a novel computational model to predict disease-associated microbes. Specifically, we first constructed a heterogeneous interconnection network based on known microbe-disease associations deposited in a few databases, the similarity between diseases, and the similarity between microorganisms. We then predicted novel microbe-disease associations by a new method called the double-ended restart random walk model (DRWHMDA) implemented on the interconnection network. In addition, we performed case studies of colon cancer and asthma for further evaluation. The results indicate that 10 and 9 of the top 10 microorganisms predicted to be associated with colorectal cancer and asthma were validated by relevant literatures, respectively. Our method is expected to be effective in identifying disease-related microorganisms and will help to reveal the relationship between microorganisms and complex human diseases.

Abstract:
Sheath blight is an important disease in corn. The disease could cause significant yield loss when infection occurs on susceptible varieties. Disease control using the microorganism antagonist is an alternative for disease management. Research was carried out in a laboratory, greenhouse and field from 2010 to 2012. The research objective was to compare several biological agents for controlling sheath blight disease on corn. In vitro laboratory tests identified that out of sixteen isolates of microorganisms, only 3 isolates which had the potency to suppress the pathogen of sheath blight over 50%, namely TT1; TM; and GM. Conidia development among the three isolates of microorganism the highest was by TT1. In the greenhouse, three isolates of microorganisms showed potential of decreasing sheath blight disease up to 70%. The Gliocladium isolates decreases the disease by 53%. Research results from the field indicated the antagonist had decreased sheath blight disease by 67%. Isolates of Trichoderma and Gliocladium fungus could reduce the yield loss by 23% by suppressing the infection of sheath blight disease.

Abstract:
Abstract Context.—The National Inventory of Clinical Laboratory Testing Services (NICLTS) was designed to give an unbiased estimate of all patient testing performed by laboratories registered under the Clinical Laboratory Improvement Amendments in 1996. Objective.—Survey data were used to develop a profile of laboratory testing primarily intended to identify microorganisms or antibodies to these microorganisms. Design.—Estimates of the extent of microorganism identification were derived from the NICLTS database by identifying associated tests and methods. The volumes for tests performed at locations that primarily prepared blood components for distribution were excluded. Organisms of public health importance were identified from the National Notifiable Disease list maintained by the Centers for Disease Control and Prevention. Participants.—Laboratories that were enrolled in the 1996 Online Certification Survey and Reporting System, maintained by the US Health Care Finance Administration, and that performed laboratory testing in 1996. Outcome Measure.—Estimated volumes and associated confidence limits by test, method, specimen type, public health importance, and testing location. Results.—Excluding testing of the blood supply, 315 million tests (95% confidence limits, 280–354 million tests) were performed in the United States for microorganism identification. Those tests for which public health consensus requires national reporting represented 38% of this total. Although hospitals performed 46% of all microorganism identification, they only performed 33% of the testing for microorganisms of public health importance. Independent and specialty laboratories performed 38% of all testing but 65% of the testing for microorganisms of public health importance. Direct methods (methods not involving culture) were used in 77% of the tests for microorganisms of public health importance and in 42% of all identification tests. Conclusions.—The distribution of microorganism identification testing found using NICLTS data is consistent with plans to modernize the public health surveillance system in the United States.

Abstract:
The ability to mount an efficient immune response should be an important life-history trait as parasitism can impact upon an individual's fecundity and survival prospects, and hence its fitness. However, immune function is likely to be costly as resources must be divided between many important traits. Whilst many studies have examined host resistance to particular parasite types, fewer have considered general immune responses. Studies that have considered general immune responses tend to do so in vertebrate models. However, the complexity of the vertebrate immune system makes the examination of evolutionary aspects of immune function difficult. Using larvae of the genus Spodoptera (Lepidoptera: Noctuidae) as a model system, this study examines' genetic and phenotypic aspects of innate immunity. The aims were to assess the levels of additive genetic variation maintained in immune traits, to consider possible costs that could maintain this variation, and to assess the role of phenotypic plasticity in ameliorating those costs. A key finding of this study was that high levels of additive genetic variation were maintained in all of the measured Immune traits. Analysis of the genetic correlations between traits revealed potential trade-offs within the immune system and between immune components and body condition. In addition, it was shown that larvae living at high densities invest more in immune function than those living in solitary conditions, suggesting that larvae can minimise the costs of immune function by employing them only when the risk of pathogenesis is high.

Abstract:
Prion diseases or transmissible spongiform encephalopathies (TSE) are characterised by the accumulation of a misfolded conformer (PrPSc) of a host encoded protein (PrPC). The misfolding event that leads to the formation PrPSc can be replicated in the in vitro amplification technique, protein misfolding cyclic amplification (PMCA). This thesis focuses on the application PMCA to study multiple aspects of prion misfolding in relation to ruminant prion diseases, specifically developing techniques to detect and characterise PrPSc in scrapie and BSE infections. Utilising recombinant hamster PrP (rPrP) as substrate in PMCA, multiple genotypes of scrapie were successfully amplified in an attempt to describe a quantifiable technique applicable to a wide range of scrapie isolates. Observations of non-specific protease resistant rPrP formation was investigated with modifications to the PMCA methodology, which ultimately proved unsuccessful in reducing non-specific protease resistant rPrP. Using brain PrPC as substrate, the quantitative PMCA technique was piloted with BSE to correlate in vitro replication efficiency with infectious titre in mouse bioassay, but no correlation was identified. Atypical forms of BSE occur primarily in older cattle, are asymptomatic and thought to be spontaneous diseases. None the less, infection models in rodents and primates have identified the zoonotic potential of H-type and L-type BSE. Therefore PMCA methods were developed which were able to successfully amplify both atypical forms of BSE. In particular, sensitive detection and discrimination from classical BSE was demonstrated for H-type BSE, which has not previously been amplified in PMCA. H-type BSE could be detected in 1x10¬-12 g brain material and was discriminated from classical BSE by increased protease sensitivity, relatively high molecular weight and antibody reactivity. Evidence exists for co-infection of TSE strains, yet scrapie and BSE co-infection in an ovine host remains unaddressed. To study the disease progression and tissue dissemination of co-infections a PMCA assay capable of specifically amplifying BSE PrPSc in the presence of excess scrapie was applied to artificially mixed brain homogenates containing BSE and scrapie, and compared to current statutory strain typing methods. The PMCA was found to have sensitivity and specificity of 100% in mixes containing 0.1% BSE and 99.9% scrapie brain material, which was more effective than conventional strain typing methods. The assay was then applied to the brain, spleen and lymph of scrapie and BSE experimental co-infections in two genotypes of sheep, and to animals which belonged to a flock with endemic natural scrapie and that also received experimental BSE infections. The PMCA data demonstrated that sheep with PRNP genotype ARQ/ARQ (at amino acid positions 134, 154 and 171) were resistant to BSE in a co-infection scenario. In sheep with PRNP genotype of VRQ/ARQ, mixed infections could occur, and animals with scrapie PrPSc only in the brain could harbour BSE PrPSc in peripheral tissues. Co-infection was also possible in sheep with natural scrapie infections. The assay was compared to conventional testing methods of western blotting, PrPd profiling and immunohistochemistry and displayed superior sensitivity in BSE detection. PMCA amplification of bovine BSE isolates in ovine substrates identified several instances in which the molecular characteristics of the PrPSc was scrapie-like in terms of molecular weight, antibody reactivity and glycoform profile, and in some cases PrPSc characteristic of BSE could no longer be recovered. This occurred in a genotype specific manner, ‘molecular switching’ was only apparent in ovine substrate VRQ/VRQ in accordance with previous findings. These results raise the possibility of such an event occurring in in vivo ovine BSE infections and the zoonotic potential of these scrapie like conformers are yet to be fully addressed.

Abstract:
Diarrhoeal disease is a major cause of mortality in children in developing countries. It also remains a serious problem among all age groups throughout the world. Whereas studies to determine the epidemiological and aetiological factors of diarrhoeal disease have been reported for other parts of South Africa and the world, as yet no information is available for the Eastern Cape. Therefore this study was undertaken to determine the factors for this area. Enteropathogens were compared for the different ages in the various population groups and, where possible, seasonal and geographical differences were emphasised. A total of 7 278 faecal samples were examined by six laboratories in the Eastern Cape during the period November 1988 to October 1990. Data was recorded noting the age, sex and population group of the patients. The towns selected were Port Elizabeth, Uitenhage, Cradock, Grahamstown and their surrounding areas. The isolation rates for the pathogens studied in the various population groups were compared to those reported in similar studies in other countries. The seasonal incidences of the various selected pathogens were compared with those reported from elsewhere in South Africa. It was thought that the higher temperature of summer may influence the finding in the White population group, while rainfall would play a greater role for the Coloured and Black populations. The geographical distribution of the pathogens emphasised the difference in living conditions between the different population groups. For example a generally higher infestation rate of Helminths occurred in rural areas and in the groups living under poorer conditions. The low isolation rates for certain bacteria and the large percentage of samples from which no pathogens were isolated indicate the need for further research. However, the finding should be valuable for determining Public Health priorities and in the management of outbreaks of diarrhoeal disease.

ENGLISH ABSTRACT: Petri disease and esca are devastating grapevine trunk diseases and compromise the sustainability of viticulture world-wide. Despite being extensively studied, knowledge of inoculum sources and mechanisms of spread of the causal pathogens is limited. Arthropods have been suspected to play a role in the spread of Petri disease and esca pathogens. However, little information is known about the extent to which arthropods are associated with these pathogens. This study aimed to determine whether arthropods occurring within or on declining grapevines, are associated with trunk disease pathogens and to identify arthropods associated with pruning wounds. The potential of selected arthropods to act as vectors of trunk disease pathogens was also investigated. Two vineyards exhibiting grapevine trunk disease infections were sampled weekly for two years for collection of arthropods. Arthropods were collected using pruning wound traps, visual searches as well as trunk and cordon traps. Fungal spores from surfaces of arthropods were collected in water. Samples were subjected to nested PCR using primers Pm1/Pm2 and Pch1/Pch2 to verify the presence of Phaeoacremonium spp. and Phaeomoniella chlamydospora, respectively. Water samples were also cultured and grapevine trunk disease pathogens obtained were identified by sequencing the internal transcribed spacers 1 and 2 and the 5.8S rRNA gene or the partial beta-tubulin gene. A total of 10 875 arthropod individuals, belonging to more than 31 families, were collected from declining grapevines. The most abundant arthropods included millipedes, ants, spiders and beetles. Portuguese millipedes and cocktail ants were associated with fresh grapevine pruning wounds. Thirty-three percent of the 5677 water samples analysed, contained propagules of pathogens associated with Petri disease and esca. Of these, 37 % were recovered from millipedes, 22 % from cocktail ants, 15 % from spiders and 10 % from beetles. All the major groups of grapevine trunk diseases were detected on the arthropods. Phaeoacremonium species were detected in 1242 samples while Phaeomoniella chlamydospora was identified from 855 samples. Other fungi isolated included members of the Botryosphaeriaceae, Diatrypaceae and Diaporthales. The potential of grapevine sap as a food source for Portuguese millipedes and cocktail ants was investigated, in vitro. Millipede individuals were offered a choice between water and grapevine sap while ants in nests were presented with grapevine sap, tuna and water and monitored for ingestion of sap. Both taxa preferred grapevine sap over the other food items, indicating close association with pruning wounds. Subsequently, the ability of both taxa to transmit a DsRed-transformed Phaeomoniella chlamydospora isolate to fresh pruning wounds of canes in polystyrene strips, floating in water, and potted vines was tested. Arthropods were exposed to the fungus for 24 hours and transferred to the base of the plants and canes and were removed after three days. Isolations after a month revealed that millipedes and ants were capable of transmitting the fungus onto wounds and cause infection. Millipede faecal pellets were also evaluated as potential sources of inoculum. Millipedes were fed on Phaeomoniella chlamydospora for 24 hours, surface sterilised and allowed to defaecate in sterile Petri dishes overnight. Faecal material was collected, macerated in water and plated onto potato dextrose agar. Propagules of Phaeomoniella chlamydospora survived passage through the gut of millipedes and were passed out in a viable state to form colonies of Phaeomoniella chlamydospora. This study concludes that a wide variety of arthropods can be a source of inoculum of trunk diseases in vineyards. The results of the dissemination trial provides evidence that millipedes and ants are able to disseminate and infect vines with Phaeomoniella chlamydospora. It is therefore, highly likely that other grapevine trunk disease pathogens are transmitted in the same manner. This knowledge highlights the need for control of certain arthropods to be taken into consideration when managing grapevine trunk disease pathogens.
AFRIKAANSE OPSOMMING: Petri siekte en esca is verwoestende wingerd stamsiektes en verhinder die volhoubaarheid van wingerdproduksie wêreldwyd. Hierdie siektes is al intensief bestudeer, maar kennis rakende die inokulum bronne en meganismes van verspreiding van die veroorsakende patogene is beperk. Arthropoda is al vermoed om ‘n rol te speel in die verspreiding van Petri siekte en esca patogene, maar weinig informasie is bekend oor die mate waartoe arthropoda geassosieer is met die patogene. Hierdie studie het ten doel gestel om die arthropoda wat op of in wingerdstokke wat terugsterf voorkom te identifiseer en te bepaal watter van die arthropoda geassosieer is met stamsiekte patogene. Daar is ook ten doel gestel om die arthropoda wat geassosieer is met vars snoeiwonde te identifiseer en ook die moontlike vektor status van die stamsiekte patogene deur arthropoda. Arthropoda is weekliks vir twee jaar gekollekteer vanaf twee wingerde met stamsiekte infeksies. Snoeiwond lokvalle, visuele soektogte en stam- en kordon lokvalle was gebruik om arthropoda te vang. Swamspore van die oppervlak van die arthropoda is afgewas met water. Van hierdie water monsters is gebruik om dubbelvoudige polimerase ketting reaksies (PKR) te doen met die inleiers Pm1/Pm2 en Pch1/Pch2 om vir die teenwoordigheid van Phaeoacremonium spp. en Phaeomoniella chlamydospora onderskeidelik te toets. Die oorblywende water monster is gekweek op medium om die swamme teenwoordig te bepaal. Die wingerd stamsiekte patogene is verder geidentifiseer deur die DNS volgordes te bepaal van die interne getranskribeerde spasies 1 en 2 en die 5.8S rRNS geen of ‘n gedeelte van die beta-tubulien geen. In totaal is 10 875 arthropoda, wat behoort tot 31 families, gekollekteer vanaf wingerde wat terugsterf. Die mees algemene arthropoda was duisendpote, miere, spinnekoppe en kewers. Die Portugese duisendpote en die wipstert mier is geassosieer met vars wingerd snoeiwonde. Van die 5677 water monsters wat geanaliseer is, het 33% propagules van die Petri siekte of esca patogene gehad. Van hierdie was 37 % afkomstig vanaf duisendpote, 22 % van wipstert miere, 15 % van spinnekoppe en 10 % van kewers. Al die hoofgroepe van wingerd stampatogene is opgespoor op die arthropoda. Phaeoacremonium species is opgespoor in 1242 monsters en Phaeomoniella chlamydospora is gevind in 855 monsters. Ander swamme wat ook geisoleer is sluit lede van die Botryosphaeriaceae, Diatrypaceae en Diaporthales in. Die potensiaal van wingerdsap as ‘n bron van voedsel vir Portugese duisendpote en wipstert miere is in vitro ondersoek. Duisendpoot invidue is ‘n keuse gegee tussen water en wingerd sap terwyl mierneste ‘n keuse gehad het tussen water, wingerd sap en tuna. Die duisendpote en miere is gemonitor vir die inname van wingerdsap in die teenwoordigheid van die ander bronne. Beide die duisendpote en miere het wingerdsap verkies wat aandui dat hulle ‘n noue assosiasie met wingerd snoeiwonde het. Vervolgens is beide taksons getoets vir hul vermoë om ‘n DsRooi-getransformeerde Phaeomoniella chlamydospora isolaat te vektor na vars snoeiwonde op lote gemonteer op polistireen stroke wat in water dryf en op wingerd plante in potte. Die duisendpote en miere is blootgestel aan die swam vir 24 uur en oorgedra na die basis van die plante en lote en is weer verwyder na drie dae. Na ‘n maand is isolasies gedoen wat gewys het dat die duisendpote en miere die swam suksesvol kon oordra na die snoeiwonde en infeksie veroorsaak. Duisendpoot uitwerpsels is geëvalueer vir die potensiaal as inokulum bron. Duisendpote het gevoed op Phaeomoniella chlamydospora vir 24 uur, daarna oppervlakkig gesteriliseer en toegelaat om oornag uitwerpsels te maak in steriele Petri bakkies. Uitwerpsels was gekollekteer, fyngemaak in water en op aartappel dekstrose agar uitgeplaat. Propagules van Phaeomoniella chlamydospora het die verteringskanaal van die duisendpote oorleef en het tipiese kolonies op die agar gevorm. Hierdie studie het vasgestel dat ‘n verskeidenheid van arthropoda ‘n bron van inokulum van stamsiektes in wingerd kan wees. Die resultate van die vektor proewe het gewys dat duisendpote en miere die vermoë het om Phaeomoniella chlamydospora te versprei na snoeiwonde wat die swam dan suksesvol geinfekteer het. Dit is daarom hoogs waarskynlik dat van die ander wingerd stamsiekte patogene ook versprei kan word op dieselfde manier. Hierdie kennis demonstreer dat die beheer van spesifieke arthropoda in ag geneem moet word in die bestuur van wingerd stamsiektes.

Abstract:
One of the modern techniques of improving microbial preparations efficiency is a combination of several microorganisms with different beneficial properties in one inoculant. Taking into account the role of nitrogen and potassium nutrition and their synergism, it is essential to develop preparations of N2-fixing and K-mobilizing rhizobacteria, especially Azospirillum sp. and Bacillus sp. Effective biological control of root infections is of great importance in order to prevent crop yield losses. Among soil antagonistic fungi, Trichoderma sp. is the most promising one. Microbial inoculant includes three components: Azospirillum brasilеnse 2(b)3 + Bacillus circulans K-81 + Trichoderma longibrachiatum L-7 (1:1:1). Combined application of rhizobacteria A. brasilense + B. сirculans induced significant hormonal effect. Roots dry mass increased by 28%, roots length per plant – by 25%, stem dry mass – by 33%. In the field experiment, the treatment of barley by microbial inoculant provided the reduction of root rot incidence by 52.0–58.0%, disease development (waxy ripeness) – by 2.6–2.9 times, biological efficiency was 66.3–69.5%. Treatment of winter rye resulted in the reduction of disease incidence by 42.4–45.0%, disease development (milky ripeness) – by 2.0–2.6 times, biological efficiency – 50.2–61.2% according to soil-erosion catena. Beneficial influence of inoculation on plant development and nutrition, as well as effective biological control of plant diseases, provided significant crop responses: for winter rye – 3.8-4.5 c ha-1 or 7.0% - 9.8%, for spring barley – 5,2 – 4.9 c ha-1 or 9.3% – 9.2% according to soil-erosion catena. Microbial inoculant exhibits the properties of plant growth promoter, biological fertilizer, and biological fungicide.

Multifunctional biological products based on strains of microorganisms that are antagonists of pathogens and plant disease resistance activators - chitosan and its derivatives increase the content of chlorophyll α and b in flag leaves of wheat, the number and weight of grains in the ear, potential yield, and also reduce the development of yellow rust. The maximum biological effectiveness for these indicators was noted in the experimental version, where Bacillus subtilis VKM B-2604D and B. subtilis VKM B-2605D strains that are part of the Vitaplan biological product and chitosan salicylate (Chitosan II) complex was used.

Abstract:
Microorganisms are the most important bioindicators of the environment and ecological risk assessment. The impact of the no-till farming system in combination with microbial preparations needs to be studied and is an urgent task aimed at preserving fertility. The aim of our study was to determine the effect of pre-sowing inoculation with complex microbial preparations (CMP) and farming systems (no-till and conventional farming system) on the microbocenosis of the rhizosphere of Triticum aestivum L. in the Crimean Steppe. Microbiological analysis of the rhizosphere showed a significant increase in the number of actinobacteria (twice). The number of micromycetes, among which there are many pathogens of various plant diseases, decreased under direct sowing by 23 % as a result of inoculation and amounted to 21.5 thousand CFU/g of soil. The number of cellulose-destroying microorganisms that form soil fertility increased under the influence of microbial preparations by 23 % under conventional farming system (10.0 thousand CFU/g of soil); by 20 % under no-till (15.4 thousand CFU/g of soil). Thus, it was found that the use of microbial preparations under both farming techniques contributed to an increase in the number of microorganisms of most ecological-trophic groups that participate in the transformation of nitrogen in the rhizosphere, enhanced enzymatic processes, reduced the development of pathogenic microbiota and, consequently, contributed to improving the state of soil biocenosis.
