Mycotoxin problem in Africa: Current status, implications to food safety and health and possible management strategies
(2008)
Mycotoxins are toxic secondary metabolites of fungal origin and contaminate agricultural commodities before or under post-harvest conditions. They are mainly produced by fungi in the Aspergillus, Penicillium and Fusarium ...
Levels of toxic metals in multisectoral samples from Winam Gulf of Lake Victoria.
(2009)
In this study, the distribution and sources of inputs of trace metals including Cd, Cu, Zn and Pb from various sources as well as Fe which is widely used in the construction industry, into Winam Gulf of Lake Victoria were ...
Linkage disequilibrium between alleles at highly polymorphic mini- and micro-satellite loci of Theileria parva isolated from cattle in three regions of Kenya
(2006)
Theileria parva schizont-infected lymphocyte culture isolates from western, central and coastal Kenya were analysed for size polymorphism at 30 T. parva-specific variable number tandem repeat (VNTR) loci using a panel of ...
In vivo screening of antimalarial activity of Acacia mellifera (Benth) (Leguminosae) on Plasmodium berghei in mice.
(2007)
The activities of total extracts and lupane triterpenes, isolated from the stem bark of Acacia mellifera, were evaluated against Plasmodium berghei strain ANKA in a female Swiss mouse model. Five isolated compounds and the ...
Half-precessional dynamics of monsoon rainfall near the East African Equator.
(University of Nairobi,, 2009-12)
External climate forcings-such as long-term changes in solar insolation-generate different climate responses in tropical and high latitude regions. Documenting the spatial and temporal variability of past climates is ...
Cytotoxic lupane-type triterpenoids from Acacia mellifera.
(2004)
One new and eight previously described lupane-type metabolites were isolated for the first time from Acacia mellifera (Leguminosae). Based on spectral analyses, the structure of the new compound was elucidated as ...
Phylogenetic analysis of the microbial populations in the wild herbivore gastrointestinal tract: insights into an unexplored niche
(2003)
At present, there is little information on the phylogenetic diversity of microbial species that inhabit the gastrointestinal tracts of wildlife. To increase understanding in this area, we initiated a characterization of ...
A panel of microsatellite and minisatellite markers for the characterisation of field isolates of Theileria parva
(2003)
Mini- and microsatellite sequences show high levels of variation and therefore provide excellent tools for both the genotyping and population genetic analysis of parasites. Herein we describe the identification of a panel ...
Diversity of lepidopteran stem borers on monocotyledonous plants in eastern Africa and the islands of Madagascar and Zanzibar revisited.
(University of Nairobi, 2006)
Surveys were completed in Eritrea, Ethiopia, Kenya, Madagascar, Mozambique, Tanzania, Uganda and Zanzibar to assess the lepidopteran stem borer species diversity on wild host plants. A total of 24,674 larvae belonging to ...
Identifying human and livestock sources of fecal contamination in Kenya with host-specific Bacteroidales assays.
(University of Nairobi, 2009-11)
Microbial source tracking to distinguish between human, livestock and wildlife fecal pollution using molecular techniques is a rapidly evolving approach in many developed countries, but has not previously been applied on ...
