Compartment-specific bacterial communities in higher termites
(M icroha bitat-specificity of the hindgut microbiota in higher termites, 2013)The higher termite gut is a highly structured habitat and shows the presence of spatially separated compartments. The differences in physicochemical parameters between the compartments, most importantly pH, play an important ... -
Isolation and characterization of actinobacteria with potential for control of fusarium spp and colletotrichum kahawae
(Jomo Kenyatta University of Agriculture and Technology, 2007)Smallholder subsistence farming is important in the production of food crops for basic livelihoods and income generation in rural areas. However, yields have remained low due to high disease, weed and pest incidences. ... -
Isolation and characterization of Streptomyces species with antifungal activity from selected national parks in Kenya
(African Journal of Microbiology Research, 2010)Microorganisms and their natural products are potentially important for the biological control of crop diseases without detrimental effects to the environment. In this study, acetonitrile-methanol extracts of 361 ... -
Growth characteristics and production of secondary metabolites from selected novel Streptomyces species isolated from selected Kenyan national parks
(JKUAT ANNUAL SCIENTIFIC CONFERENCE PROCEEDINGS, 2010)The aim of study was to characterize growth of novel Streptomyces isolates as well as the secondary metabolites they were producing. Four Streptomyces isolates from Chyulu National Park (Chy 4 -10, Chy 15-10, Chy 15-5 and ... -
Optimization of growth conditions and characterization of enzymatic activity of selected novel Streptomyces species from Kenyan soils
(Scientific Conference Proceedings, 2012-06-14)This study was aimed at unveiling and assessing protease, esterase, amylase and lipase enzymes from selected novel Streptomyces species with biotechnological interest. Four Streptomyces isolates from Jomo Kenyatta University ... -
“Methanoplasmatales,” Thermoplasmatales-related archaea in termite guts and other environments, are the seventh order of methanogens
(American Society for Microbiology, 2012-12-01)The Euryarchaeota comprise both methanogenic and nonmethanogenic orders and many lineages of uncultivated archaea with unknown properties. One of these deep-branching lineages, distantly related to the Thermoplasmatales, ... -
Archaeal diversity and community structure in the compartmented gut of highert termites
(Philipps-Universität Marburg, 2013)Termites are phylogenetically divided into lower and higher termites (Inward et al., 2007). The higher termites, which constitute three quarter of all known termite species, are represented by only one family Termitidae, ... -
Metagenomic analysis of the microbiota in the highly compartmented hindguts of six wood-or soil-feeding higher termites
(BioMed Central, 2015-12-01)Termites are important contributors to carbon and nitrogen cycling in tropical ecosystems. Higher termites digest lignocellulose in various stages of humification with the help of an entirely prokaryotic microbiota housed ... -
Evaluation of cercaricidal and miracicidal activity of selected plant extracts agains larval stages of Schistosoma mansoni
(Journal of Natural Sciences Research, 2016)Schistosomiasis is a parasitic disease caused by blood-flukes of the genus Schistosoma. It is one of the most widespread of all human parasitic diseases, ranking second only to malaria in terms of its socioeconomic and ... -

Enzymatic Activity of Endophytic Bacterial Isolates from Selected Mangrove Plants in Kenya
(The Open Microbiology Journal, 2018-11-14)Microorganisms are a preferred source of enzyme production due to their high production capability and low cost of production. Bacterial endophytes occupy unexplored sites hence they represent a new source of enzymes with ... -
CHAPTER EIGHTEEN A BIORATIONALE FOR CONTROL OF BIOMPHALARIA PFEIFFERI HOST SNAILS, LARVAE OF ANOPHELES GAMBIAE AND SCHISTOSOMA MANSONI
(Cambridge Scholars Publishing, 2019-11-14)Mosquitoes transmit deadly diseases in tropical countries. Despite tremendous efforts towards disease control, the burden is still huge in endemic areas. In 2015, the region was home to 89% of malaria cases and 91% of ... -
16S rRNA gene profiling of bacterial communities mediating production of tsetse attractive phenols in mammalian urine
(AOSIS Publishing, 2019)Several types of odours are involved in the location of host animals by tsetse (Diptera: Glossinidae), a vector of animal African trypanosomiasis. Host animals' ageing urine has been shown to be the source of a phenolic ... -
