Seasonal changes in mosquito population densities in irrigated and non-irrigated areas in Bura, Tana River County, Kenya (2013-2014)R. Sang, J. Lutomiah, J.F. Lindahl, D. Grace & B. Bett
These data comprise apparent densities, species and sex and of mosquitos collected in irrigated and non-irrigated areas in Bura, Tana River County Kenya, between September 2013 and November 2014. Sampling was repeated four times over the period to cover the wet season, dry season, irrigation season and fallow periods. Mosquitoes were trapped using carbon dioxide-baited (CDC) light traps. Mosquitoes harvested from each of these traps were immobilized using 99.5% triethyleamine (Sigma-Aldrich, St. Louis, Missouri) and...
Data from: Multiple evolutionary origins of Trypanosoma evansi in KenyaChristine M. Kamidi, Norah P. Saarman, Kirstin B. Dion, Paul O. Mireji, Collins Ouma, Grace Murilla, Serap Aksoy, Achim Schnaufer, Adalgisa Caccone & Kirstin Dion
Trypanosoma evansi is the parasite causing surra, a form of trypanosomiasis in camels and other livestock, and a serious economic burden in Kenya and many other parts of the world. Trypanosoma evansi transmission can be sustained mechanically by tabanid and Stomoxys biting flies, whereas the closely related African trypanosomes T. brucei brucei and T. b. rhodesiense require cyclical development in tsetse flies (genus Glossina) for transmission. In this study, we investigated the evolutionary origins of...
Data from: Examining the human infectious reservoir for Plasmodium falciparum malaria in areas of differing transmission intensityBronner P. Gonçalves, Melissa C. Kapulu, Patrick Sawa, Wamdaogo M.

A detailed understanding of the human infectious reservoir is essential for improving malaria transmission-reducing interventions. Here we report a multi-regional assessment of population-wide malaria transmission potential based on 1209 mosquito feeding assays in endemic areas of Burkina Faso and Kenya. Across both sites, we identified 39 infectious individuals. In high endemicity settings, infectious individuals were identifiable by research-grade microscopy (92.6%; 25/27), whilst one of three infectious individuals in the lowest endemicity setting was detected by...
Data from: Microbiome sharing between children, livestock and household surfaces in western KenyaEmily Mosites, Matt Sammons, Elkanah Otiang, Alexander Eng, Ceclia Noecher, Ohad Manor, Sarah Hilton, Samuel M.

Palmer, Joel Montgomery, Elhanan Borenstein, Richard Omore, Peter M. Rabinowitz, Samuel M. Thumbi & Cecilia Noecker
The gut microbiome community structure and development are associated with several health outcomes in young children. To determine the household influences of gut microbiome structure, we assessed microbial sharing within households in western Kenya by sequencing 16S rRNA libraries of fecal samples from children and cattle, cloacal swabs from chickens, and swabs of household surfaces. Among the 156 households studied, children within the same household significantly shared their gut microbiome with each other, although we...
