Virulence and antimicrobial resistance genes are enriched in the plasmidome of clinical Escherichia coli isolates compared with wastewater isolates from western Kenya
(Science Direct, 2021-07)Many low-middle income countries in Africa have poorly-developed infectious disease monitoring systems. Here, we employed whole genome sequencing (WGS) to investigate the presence/absence of antimicrobial resistance (AMR) ... -
Assessment of potential risks and effectiveness of agrochemical usage in a catchment: a case study of the Nzoia Nucleus Estate sugarcane farms in western Kenya
(Science Direct, 2018-05)Monitoring of agronomic inputs such as pesticides and fertilizers in canals, streams, and rivers within catchments and subsequent modeling of their fate and toxicity are useful tools in determination of their efficient ... -
Enteric bacterial communities associated with the Omubhira Stream in Kakamega County, Kenya
(Biology, 2018-07-09)The present study was undertaken to establish the distribution and diversity of enteric bacterial communities along the Omubhira stream and also determine if physico-chemical parameters influence their distribution in water ... -
Effects of environmental factors on cyanobacteria dynamics in Lake Baringo, Kenya
(Wiley Online Library, 2014-12-10)The dominance of cyanobacterial algae in light-limited, shallow freshwater Lake Baringo is a major environmental concern in regard to Kenyan water quality and public health protection agencies. Accordingly, this study ... -
Effect of vegetated filter strips on infiltration and survival rates of Escherichia coli in soil matrix at Mau, Njoro River Watershed, Kenya.
(Energy, Ecology and Environment, 2016-12-27)Overland flows contaminated with manure borne pathogens pose risks to public health, because fecal pathogens may infiltrate into soil matrix from overland flows and contaminate soil water aquifers. The objective of this ... -
Insecticide resistance exerts significant fitness costs in immature stages of Anopheles gambiae in western Kenya
(Malaria Journal, 2021-06-09)Background Despite increasing documentation of insecticide resistance in malaria vectors against public health insecticides in sub-Saharan Africa, there is a paucity of information on the potential fitness costs of ... -
On A Class of Idealized Near-Rings Admitting Frobenius Derivations.
(Journal of Advances in Mathematics and Computer Science, 2020-07-15)In this paper, we use the idealization procedure for finite rings to construct a class of quasi-3 prime Near-Rings N with a Jordan ideal J(N) and admitting a Frobenius derivation. The structural characterization of N; J(N) ... -
Calibration and validation of the AquaCrop model for full and deficit irrigated cowpea (Vigna unguiculata (L.) Walp)
(Science Direct, 2020-10-16)The study aimed at calibrating and validating the AquaCrop model for cowpea under full and deficit irrigation. The experiments used to calibrate and validate AquaCrop consisted of rainfed supplemented with irrigation, ... -
Managing the invasion of guava trees to enhance carbon storage in tropical forests
(Science Direct, 2019-01-15)Tropical forests account for a substantial percentage of the world’s carbon stocks, but the consequences to carbon storage of the rapid invasiveness of the guava tree in these forests is not known. Two different forest ... -
Composition and design of vegetative filter strips instrumental in improving water quality by mass reduction of suspended sediment, nutrients and Escherichia coli in overland flows in eastern escarpment of Mau Forest, Njoro River Watershed, Kenya.
(Energy, Ecology and Environment, 2013-06-13)This study assessed the effect of vegetative filter strip (VFS) in removal of suspended sediment (SS), total nitrogen, total phosphorus and Escherichia coli (E. coli) in overland flow to improve receiving water quality ... -
Prospects for Developing Odour Baits To Control Glossina fuscipes spp., the Major Vector of Human African Trypanosomiasis.
(plos neglected tropical diseases, 2009-05-12)We are attempting to develop cost-effective control methods for the important vector of sleeping sickness, Glossina fuscipes spp. Responses of the tsetse flies Glossina fuscipes fuscipes (in Kenya) and G. f. quanzensis (in ... -
Differential attractiveness of human foot odours to Anopheles gambiae Giles sensu stricto (Diptera: Culicidae) and variation in their chemical composition
(Science Direct, 2013-10-01)Counter flow geometry (CFG) traps (American Biophysics) baited with foot odours (adsorbed overnight on a combination of a nylon and a cotton socks) from 4 groups of 4 male volunteers were initially used in a screen-house ... -
