Nitrogen and phosphorous uptake by potato (Solanum tuberosum L.) and their use efficiency under potato-legume intercropping systems
(University of Nairobi, 2018)
Competition for nitrogen (N) and phosphorous (P) under potato-based intercropping systems decreases the level of nutrients available for potato and subsequently influences nitrogen and phosphorous use efficiency. A field ...
Seroepidemiological Survey of Rift Valley Fever Virus in Ruminants in Garissa, Kenya
(University of Nairobi, 2017)
Introduction: Rift Valley fever (RVF) is a vector-borne zoonotic disease caused by phlebovirus in the family Bunyaviridae. In Kenya, major outbreaks occurred in 1997–1998 and 2006–2007 leading to human deaths, huge economic ...
Essential oils of indigenous plants protect livestock from infestations of Rhipicephalus appendiculatus and other tick species in herds grazing in natural pastures in western Kenya
(University of Nairobi, 2018)
The effects of formulated essential oils of Tagetes minuta and Tithonia diversifolia on Rhipicephalus appendiculatus infesting livestock were evaluated in semi-field experiments. Forty-five zebu cattle naturally infested ...
Variation in host preferences of malaria mosquitoes is mediated by skin bacterial volatiles.
(University of Nairobi, 2017)
The host preferences of the anthropophilic mosquito species in the Anopheles gambiae complex (Diptera: Culicidae) are mediated by skin bacterial volatiles. However, it is not known whether these mosquitoes respond ...
Age and Origin of the Tsavorite and Tanzanite Mineralizing Fluids in the Neoproterozoic Mozambique Metamorphic Belt
(University of Nairobi, 2017)
The genetic model previously proposed for tsavorite- (and tanzanite-) bearing mineralization hosted in the Neoproterozoic Metamorphic Mozambique Belt (stretching from Kenya through Tanzania to Madagascar) is refined on the ...
Prevalence of fibromyalgia syndrome in diabetics with chronic pain at the Kenyatta National Hospital
(University of Nairobi, 2017)

Mycoplasma genitalium Infection in Kenyan and US Women.
(Wolters Kluwer, 2018-08)
Little is known about the natural history of Mycoplasma genitalium (MG) infection in women. We retrospectively tested archived vaginal fluid samples to assess MG prevalence, incidence, persistence, recurrence and antimicrobial ...
Vegetative compatibility and phenotypic characterization as a means of determining genetic diversity of Aspergillus flavus isolates
(University of Nairobi, 2018)
oxigenic Aspergillus species produce mycotoxins that are carcinogenic, hepatotoxic and teratogenic immunosuppressing agents in both human and animals. Kenya frequently experiences outbreaks of aflatoxicosis with the worst ...
Naphthalene Derivatives from the Roots of Pentas parvifolia and Pentas bussei
(University of Nairobi, 2016)
The phytochemical investigation of the CH2Cl2/MeOH (1:1) extract of the roots of Pentas parvifolia led to the isolation of three new naphthalenes, parvinaphthols A (1), B (2), and C (3), two known anthraquinones, and five ...
Fever of unknown origin: A rheumatologic perspective
(University of Nairobi, 2018)
Fever of Unknown Origin (FUO) is a syndrome defined by persistent fevers above 38.30C that lasts for longer than 3 weeks with no obvious source. It usually poses a diagnostic challenge to the clinician.
We describe a ...
