Safe drinking water is defined by the World Health Organization (WHO) as water that meets WHO guidelines or national standards for physical, chemical and microbial characteristics. Microbial contamination of drinking water can cause diarrheal and other waterborne diseases that cause morbidity and even mortality. Sanitary surveys which are observational checklists highlighting potential risks of contamination can be used because they are easier to implement than microbiological testing. T...
ABSTRACT The solubility of gentamicin in various formulation vehicles (oils, surfactants and co-surfactants) was determined using the shake flask method. Emulsifying ability of the surfactants for the selected oil was screened. Different SNEF prototypes were developed following the construction of ternary phase diagrams using water titration method. The effect of drug and other additives on the ternary phase diagrams were studied and the selected formulations were optimized. Optimized formul...
ABSTRACT The basic needs of people such as safe drinking water, improved hygiene and sanitation must be fulfilled for a dignified life of human beings. However, this has not been the case in Isiolo County where there is rampant practice of open defecation and reliance on unprotected water sources for drinking purposes, with little or no regard to adequate drinking water treatment handling and storage. This study sought to establish the contribution of faecal disposal practices among resident...
ABSTRACT The general objective was to evaluate the efficacy of Trichoderma species to promote the growth of tomato and to manage late blight disease under in vitro and in vivo conditions. A collection of 18 Trichoderma spp. were isolated from two commercial products (Trichotech® and Trianum-P®) that should have the antagonistic species Trichoderma asperellum and Trichoderma harzianum respectively. Cultural and molecular approaches were used to characterize the products. Differences on the g...
ABSTRACT The susceptibility, clinical signs, distribution and persistence of lesions of a local Nigeria velogenic Newcastle disease virus (VNDV) strain (KUDU 113) were studied in 6 week old chickens bursectomised by treatment with cyclophosphamide on days 2, 3 and 4 post-hatch. Following intramuscular inoculation, depression, muscle tremor, greenish diarrhea and paralysis were observed in the bursectomised infected (BI) chickens while severe depression, whitish to greenish diarrhea, listless...
ABSTRACT Pharmaceuticals are critical in maintaining the health of people and improving the quality of life for millions of Kenyans, but not all pharmaceuticals dispensed are consumed. They become waste when they are no longer usable for intended purpose or are being discarded for other reasons such as contamination and expiration. Improperly disposed pharmaceuticals end up in garbage collection centres and water purification systems which are not sufficiently equipped to manage this form of ...
ABSTRACT Gongronema latifolium is an edible tropical rainforest plant traditionally used as a spice, staple vegetable and in the treatment and management of diabetes. Extensive studies have established its hypoglycaemic effect. However, scanty information is available on the mechanism by which it exerts its hypoglycaemic effect. Studies have noted the presence of saponin in G. latifolium, a component noted to affect gastric emptying (GE). Presently, the possible effect of G. latifolium on GE...
ABSTRACT Rift valley fever (RVF) is a zoonotic disease caused by Rift Valley fever virus (RVFV) with impact on animal and human health. Vaccines developed against RVF have safety and efficacy concerns and administered by needles posing risks of RVFV transmission. This study reports the safety and immunogenicity of attenuated RVF MP-12 and its recombinant arMP-12ΔNSm21/384 vaccines. A total of 32 sheep, 15 goats and 23 zebu calves were vaccinated with 1x105 plaque forming units (PFU)/ml of M...
ABSTRACT An epidemiological survey was conducted between November and December 2007 in 30 randomly selected villages and four slaughterslabs in Mbozi and Mbeya Rural districts, southern Tanzania, to determine the prevalence of porcine cysticercosis. Fifteen villages and three slaughterslabs were from Mbozi and fifteen villages and one slaughterslab were from Mbeya Rural. A total of 600 live pigs (300 in each district) of different sex and age categories were randomly selected from smallholde...

Abstract Regional variations in splenic size and spleen parenchymal echo-texture among sickle cell disease (SCD) patients have been documented in various publications. The objectives of this study were to: determine and compare the spleen size of SCD patients with those of the control; characterize the spleen parenchymal echo-texture of SCD patients; and ascertain the relationships of age, height and weight with the spleen sizes of SCD patients and the controls. This was a cross sectional pr...
ABSTRACT Fragmentation and its effects on avifauna is a study that was conducted in upper River Njoro watershed covering about 280km2 . The watershed is under threat from increasing human activities that have led to rapid changes in land cover and deterioration of environmental and habitat conditions for birds. These include replacement of indigenous trees with exotic types, clearing of riparian vegetation, cultivation of river banks, deforestation and forest fragmentation. The study’s mai...
