Pre-Disposing Factors Contributing to the Prevalence of Intestinal Parasitic Infections (IPI) among the HIV/AIDS Patients in Bungoma County, Kenya
(International Journal of Science and Research (IJSR), 2014-12)The role of HIV infection on the pathognomomic of HIV infections is not clearly understood. The aim of the current study was to determine the epidemiology of IPI and predisposing factors among HIV/AIDS patients in Bungoma ... -
Are stingless bees the primary vector in spread of banana Xanthomonas wilt in Central Uganda?
(International Journal of Ecology and Ecosolution, 2014-09)Stingless bees were speculated to be the primary vectors in the spread of the bacterial agent responsible for banana Xanthomonas wilt (BXW) in Uganda. It was hypothesized that the vector entered the banana plant through ... -
Dynamic of Stress Response in Victoria Labeo (Labeo victorianus) during transfer from the Hatchery to cages and Ponds under Differential Caged Stocking Densities
(International Journal of Science and Research (IJSR), 2012)Variation in fish stocking densities translate to difference in growth performance, yields and economic benefits in fish culture. Transferring fish directly from hatcheries to the cages or ponds may induce stress. We ... -
Encroachment of open grasslands and Acacia drepanolobium Harms ex B.Y.Sjöstedt habitats by Euclea divinorum Hiern in Ol Pejeta Conservancy, Kenya
(African Journal of Ecology , Wiley online Library, 2013-03)Euclea divinorum, a fast establishing, unpalatable, and fire resistant bush is considered an invasive species in some parts of its range. In Ol Pejeta Conservancy (OPC), Kenya, E. divinorum bushes cover ˜27% of the total ... -
Haematological Response of Rastrineobola argentea Exposed To Subchronic Doses of Inorganic Cadmium (Cd), Methylmercury and Polychlorinated Biphenyl (PCB) via Dietary Exposure Pathway
(International Journal of Science and Research (IJSR), 2012)Haematological indices provide information on various aspects of fish health when exposed to environmental contaminants. We evaluated the effects of cadmium, methyl mercury (MeHg), and Polychlorinated Biphenyl (PCB) on the ... -
The risk of pathogenic intestinal parasite infections in Kisii Municipality, Kenya
(BMC Public Health, 2008-07)Background: Intestinal parasitic infections are among the most common infections worldwide. Various epidemiological studies indicate that the prevalence of intestinal parasites is high especially in developing countries, ... -
Lake Baringo: Addressing threatened biodiversity and livelihoods
(Lakes & Reservoirs: Research & Management, 2006-12)Lake Baringo is a shallow, internal drainage, freshwater lake located in the Kenyan Rift Valley. The lake is an important source of water for humans and livestock, as well as a significant income source for local communities ... -
Metazoan Parasites of Some Commercially Important Fish along the Kenyan Coast
(WIOMSA, 2004)The parasitic fauna of some commercial fish species along the Kenyan coast was investigated at four localities between August 2001 and March 2002. The study was carried out to establish the extent of parasitisation of ... -
Biological diversity of the Yala Swamp lakes, with special emphasis on fish species composition, in relation to changes in the Lake Victoria Basin (Kenya): threats and conservation measures
(Biodiversity & Conservation, 2003-05)During the second half of the last century, the Lake Victoria ecosystem has undergone drastic ecological changes. Most notable has been the decline in the populations of many endemic cichlid fishes. The lake has lost nearly ... -
Prevalence of intestinal parasitic infections in certified food-handlers working in food establishments in the City of Nairobi, Kenya
(Journal of Biomedical Research, 2012-03)Most intestinal parasites are cosmopolitan with the highest prevalence in the tropics and subtopics. Rural-to-urban migration rapidly increases the number of food eating places in towns and their environs. Some of these ... -
