(2014)Desertifilum is a filamentous cyanobacterium of crusts and biofilms, recently described from the extreme hot and dry Thar Desert in north–western India. A new species was isolated from a warm spring near Lake Bogoria, Kenya ... -
Identification of new sorghum genotypes resistant to the African and spotted Stem borers
(2014)Lepidopteran stemborers, mainly the African stemborer Busseola fusca Fuller and spotted stemborer Chilopartellus Swinhoe, are among the economically important pests of sorghum in Kenya. Identification of sources of resistance ... -
Interaction of Fusarium oxysporum f.sp.vasinfectum and the fungal feeding nematode Aphelechus avenae on Bt cotton
(2014)The fungal feeding nematode Aphelenchus avenae (APH) feeds on different species of fungi including Fusarium oxysporum f. sp. vasinfectum (FOV) that causes wilt in cotton. The objective of this study was to assess the ... -
Laboratory surveillance of cholera in Nyanza Province
(2014)Cholera continues to be an important cause of morbidity and mortality in many areas of the world, and there is currently a high frequency of new outbreaks in Africa. Following a confirmed cholera outbreak in Siaya, Kisumu, ... -
Complete genome sequence of Planctomyces brasiliensis type strain (DSM 5305T), phylogenomic analysis and reclassification of Planctomycetes including the descriptions of Gimesia gen. nov., Planctopirus gen. nov. and Rubinisphaera gen. nov. and emended descriptions of the order Planctomycetales and the family Planctomycetaceae
(2014)Planctomyces brasiliensis Schlesner 1990 belongs to the order Planctomycetales, which differs from other bacterial taxa by several distinctive features such as internal cell compartmentalization, multiplication by forming ... -
Antimicrobial Activity of Warbugia Ugandensis against Gramnegative Multi‐Drug resistant Bacteria
(Jomo Kenyatta University of Agriculture and Technology, 2014)The rise in antibiotic resistance has resulted in decreasing numbers of effective antimicrobial agents available to treat infections caused by multi‐drug resistant (MDR) bacteria. This has necessitated a search for new ... -
Assessment of Risk Predisposition to Human Papilloma Virus through Cervical Infections Screening of Women Attending an Outpatient Health Facility In Nairobi, Kenya
(2014)There is limited data on comparative disposition to cervical cancer among HPV infected women in Kenya. We aimed to determine the distribution of HPV infection, cervical abnormalities and infections commonly reported on ... -
Influence of large woody debris accumulations on macro invertebrate distribution in a low order forested tropical stream, Sagana river, Kenya
(Jomo Kenyatta University of Agriculture and Technology, 2014)Woody debris accumulations are important ecological components in low order forested streams. They provide forage and refuge for a macroinvertebrates, which are key trophic components for riverine fish. The occurrence ... -
