Evaluation of habitat use and ecological carrying capacity for the reintroduced Eastern black rhinoceros (Diceros bicornis michaeli) in Ruma National Park, Kenya
(John Wiley & Sons Ltd, 2019-09-29)We carried out a postrelease evaluation to determine predictors of habitat use and carrying capacity for the black rhinoceros (Diceros bicornis michaeli), which are criti‐ cal for monitoring how the Ruma National Park ... -
Effect of Implementation of Free Maternity Policy on Selected Maternal and Newborn Health Indicators in Gem Sub- County, Siaya County, Western Kenya
(Johns Hopkins University Press, 2019-08-03)Kenya introduced free maternity services in June 2013. The main study objective was to investigate the effect of this intervention on maternal and newborn health and specifically to determine differences in 4th antenatal ... -
Farm management practices and-their effects on yield, disease incidence and pest density of·banana and groundnut in western Kenya: planting density, intercropping and banana weevil Cosmopolites sordidus Germar (Gleoptera: Curculionidae) trapping
(East African Journal of Life Sciences, 2004-11-01)Studies on the effects of pseudostem trapping, plant density and intercropping on the banana weevil Cosmopolites sordidus Germar. populations and crop yields were conducted in western Kenya from 1994 to 1997. The objective ... -
Comparison of GeneXpert and line probe assay for detection of Mycobacterium tuberculosis and rifampicin-mono resistance at the National Tuberculosis Reference Laboratory, Kenya
(Springer Nature, 2019-10-15)The dual challenge of low diagnostic sensitivity of microscopy test and technical challenge of performing a TB culture test poses a problem for case detection and initiation of Tuberculosis (TB) second-line treatment. There ... -
Antibiotic resistance of Escherichia coli from humans and black rhinoceros in Kenya
(Springer Nature, 2019-12-07)Upsurge of antibiotic resistance in wildlife poses unprecedented threat to wildlife conservation. Surveillance of antibiotic resistance at the human–wildlife interface is therefore needed. We evaluated differences in ... -
Prevalence, Progression and Associated Risk Factors of Asymptomatic Peripheral Arterial Disease
(The Surgical Society of Kenya, 2017-01)Introduction: The prevalence of peripheral arterial disease (PAD) ranges between 4.5% and 57% and is independently associated with cardiovascular disease burden irrespective of symptoms. Two thirds of cases are thought to ... -
Direct and indirect effects of predation and parasitism on the Anopheles gambiae mosquito
(BioMed Central, 2020-01-30)A good understanding of mosquito ecology is imperative for integrated vector control of malaria. In breeding sites, Anopheles larvae are concurrently exposed to predators and parasites. However, to our knowledge, there is ... -
Comparison of in-house and commercial real time-PCR based carbapenemase gene detection methods in Enterobacteriaceae and non-fermenting gram-negative b...
(BioMed Central, 2017-12)Background Carbapenemase-producing gram-negative bacteria are increasing globally and have been associated with outbreaks in hospital settings. Thus, the accurate detection of these bacteria in infections is mandatory for ... -
Genetics of bi-component leukocidin and drug resistance in nasal and clinical Staphylococcus aureus in Lagos, Nigeria
(Academic Press, 2018-02-01)Background Resistant and virulent Staphylococcus aureus is a global public health challenge. Staphylococcal Bi-component leukotoxins are cytolytic to immune cells and evolve to disarm the innate immunity during infections, ... -
Rapid detection of carbapenemase-producing Acinetobacter baumannii and carbapenem-resistant Enterobacteriaceae using a bioluminescence-based phenotypic...
(Elsevier, 2014-04-01)Accurate detection of carbapenem-resistant Enterobacteriaceae (CRE) and carbapenemase-producing carbapenem-resistant Acinetobacter spp. (CP-CRA) constitutes a major challenge in laboratory diagnostics. We developed a ... -
Sacred groves (kibaga) of Mfangano Island, Lake Victoria, Kenya
(2004)A questionnaire method was used to obtain information about the sacred groves and identity of other protected and sacred plants ofMfangano Island. Some 36 sacred groves, locally known in the Suba language as Kibaga, ... -
Coming of age: steroid hormones of wild immature baboons, Papio cynocephalus.
(2005)Large gaps exist in our knowledge about common patterns and variability in the endocrinology of immature nonhuman primates, and even normal hormonal profiles during that life stage are lacking for wild populations. In the ... -
Persistence of maternal effects in baboons: Mother's dominance rank at son's conception predicts stress hormone levels in subadult males
(Academic Press, 2008-07-01)Dominance status and reproductive experience are maternal characteristics that affect offspring traits in diverse taxa, including some cercopithecine primates. Maternal effects of this sort are widespread and are sources ... -
Life history context of reproductive aging in a wild primate model
(Blackwell Publishing Inc, 2010-08-01)The pace of reproductive aging has been of considerable interest, especially in regard to the long postreproductive period in modern women. Here we use data for both sexes from a 37‐year longitudinal study of a wild baboon ... -
Balance of investment between parental care and mating effort in male baboons
(2011)Non-monogamous males that provide care to their offspring face a potential conflict in investment between paternal care and mating effort. This conflict arises either because of resource or temporal constraints. I ... -
Testosterone positively associated with both male mating effort and paternal behavior in savanna baboons (Papio cynocephalus)
(Academic Press, 2013-03-31)Testosterone (T) is often positively associated with male sexual behavior and negatively associated with paternal care. These associations have primarily been demonstrated in species where investment in paternal care begins ... -
Puberty and dispersal in a wild primate population
(Academic Press, 2013-07-01)This article is part of a Special Issue “Puberty and Adolescence”. The onset of reproduction is preceded by a host of organismal adjustments and transformations, involving morphological, physiological, and behavioral ... -
Demography of a population with a long history of poaching and the utility of the individual identification technique as a tool for monitoring intermittently studied elephant populations
(2016-09-01)In many elephant populations in Africa, adverse effects of poaching including altered age and sex structure and long calving intervals continue to negatively impact the rate of recovery. The study reported here characterized ... -
Hormonal correlates of natal dispersal and rank attainment in wild male baboons
(Academic Press, 2017-08-01)In many mammals, maturational milestones such as dispersal and the attainment of adult dominance rank mark stages in the onset of reproductive activity and depend on a coordinated set of hormonal and socio-behavioral ... -
