Lake Magadi and little are hypersaline, alkaline lakes situated in the southern part of Kenyan Rift Valley. Solutes supplied mainly by a series hot springs with temperatures as high 86 °C. Previous culture-dependent culture-independent studies have revealed diverse groups microorganisms thriving under these conditions. culture independent were based on analysis 16S rDNA but done less saline lakes. For first time, this study combined illumina sequencing amplicons both total community rRNA...
Open access to sequence data is a cornerstone of biology and biodiversity research, but has created tension under the United Nations Convention on Biological Diversity (CBD). Policy decisions could compromise research development, unless practical multilateral solution implemented. Ensuring international benefit-sharing from without jeopardising open sharing major obstacle for other UN negotiations. Here, authors propose address concerns both developing countries life scientists.
In this study, 50 in-depth interviews were carried out with women from the general population in Thika, Kenya. We explored awareness, attitudes, and behavior toward cervical cancer screening measures among women. The concept of health belief model (HBM) was used to develop topics for interviews. Our findings highlight lack awareness benefits early detection as critical barriers that affect women's participation programs. provide a basis designing programs will be acceptable accessible larger...
Total community rDNA was used to determine the diversity of bacteria and archaea from water, wet sediment microbial mats samples hot springs in Eastern lowlands Eritrea. The temperatures range 49.5 °C 100 while pH levels varied 6.97 7.54. Akwar Maiwooi have high carbonate levels. near seashore, Garbanabra Gelti, are more saline with higher sodium chlorides. Elegedi, situated Alid volcanic area, has highest temperature, iron sulfate concentrations.The five shared 901 4371 OTUs recovered three...
As a step towards better understanding of diversity and biology phages their hosts in haloalkaline Lake Elmenteita, were isolated from sediment samples overlying water using indigenous bacteria as hosts. 17 seemingly different diverse morphotypes with dimensions partly exhibiting remarkably unusual ultrastructures revealed by transmission electron microscopy. 12 clonal phage isolates further characterized. Infection capability the was optimum at 30–35°C alkali condition pH 10–12. Structural...
Methane emission by terrestrial invertebrates is restricted to millipedes, termites, cockroaches, and scarab beetles. The arthropod-associated archaea known date belong the orders Methanobacteriales, Methanomassiliicoccales, Methanomicrobiales, Methanosarcinales, in a few cases also non-methanogenic Nitrososphaerales Bathyarchaeales. However, all major host groups are severely undersampled, taxonomy of existing lineages not well developed. Full-length 16S rRNA gene sequences genomes scarce,...
Termites constitute part of diverse and economically important termite fauna in Africa, but information on gut microbiota their associated soil microbiome is still inadequate. In this study, we assessed compared the bacterial diversity community structure between termites' gut, mounds surrounding using 454 pyrosequencing-based analysis 16S rRNA gene sequences. A wood-feeder (Microcerotermes sp.), three fungus-cultivating termites (Macrotermes michaelseni, Odontotermes sp. Microtermes...
ABSTRACT Although homoacetogenic bacteria are generally considered to be obligate anaerobes, they colonize the intestinal tracts of termites and other environments that not entirely anoxic in space or time. In this study, we investigated how isolated from hindguts various respond presence molecular oxygen. All strains formed growth bands oxygen gradient agar tubes under a headspace H 2 -CO . The position coincided with oxic-anoxic interface depended on O partial pressure headspace; relative...
Previously undescribed, homoacetogenic bacteria were isolated from gut homogenates of the soil-feeding termite Thoracotermes macrothorax. The isolates slightly curved, banana-shaped rods (0·6–0·7×1·3–7·0 μm) and motile by one or more lateral flagella. In older cultures, cells formed club-like sporangia that developed into terminal, heat-resistant endospores. Cells stained Gram-positive but Gram-negative in KOH test. mesophilic grew homoacetogenically on H2/CO2 l-lactate. Strain TmAO3T, which...
Background Fungus-cultivating termites make use of an obligate mutualism with fungi from the genus Termitomyces, which are acquired through either vertical transmission via reproductive alates or horizontally transmitted during formation new mounds. Termitomyces taxonomy, and thus estimating diversity host specificity these fungi, is challenging because fruiting bodies rarely found. Molecular techniques can be applied but need not necessarily yield same outcome than morphological...
Abstract Fungus‐growing termites of the subfamily Macrotermitinae together with their highly specialized fungal symbionts ( Termitomyces ) are primary decomposers dead plant matter in many African savanna ecosystems. The provide crucial ecosystem services also by modifying soil properties, translocating nutrients, and as important drivers succession. Despite obvious ecological importance, basic features biology fungus‐growing especially remain poorly known, no studies have so far focused on...
Abstract: The susceptibility of various developmental stages Tetranychus evansi Baker & Pritchard (eggs, larvae, protonymphs, deutonymphs and adults) to the entomopathogenic fungi Metarhizium anisopliae (Metschnikoff) Sorokin Beauveria bassiana (Balsamo) Vuillemin was evaluated under laboratory conditions. Three concentrations (3.0 × 10 6 , 1.0 7 8 conidia/ml) both were used for each stage. effect fungal infection on fecundity egg fertility also investigated using species. Deutonymphs...
BackgroundContaminated food and water are acknowledged vehicles for the transmission of travelers' diarrhea (TD). Importance handlers as reservoirs enteroaggregative Escherichia coli (EAEC), enteropathogenic E (EPEC), Shiga toxin–producing (STEC) causing TD has not been clearly demonstrated.
Numerous outbreaks of cholera have occurred in Kenya since 1971. To more fully understand the epidemiology Kenya, we analyzed genetic relationships among 170 Vibrio cholerae O1 isolates at 5 loci containing variable tandem repeats. The were collected during January 2009-May 2010 from various geographic areas throughout country. grouped genetically into clonal complexes, each comprising a series genotypes that differed by an allelic change single locus. No obvious correlation between...
In this study soils from sugarcane-cultivated fields were screened for bacterial species capable of atrazine (6-chloro-N²-ethyl-N⁴-isopropyl-1,3,5-triazine-2,4-diamine) degradation due to long exposure the herbicide. To enrich degraders, Minimal Salt Medium containing as sole N source and glucose C was inoculated with impacted herbicide incubated. Bacterial growth monitored by measuring optical density. The followed residual in liquid cultures over a given time period high performance...
