Tryptophan-like and humic-like fluorophores are extracellular in groundwater: implications as real-time faecal indicators
(University of Nairobi, 2020)
Fluorescent natural organic matter at tryptophan-like (TLF) and humic-like fluorescence (HLF) peaks is associated with the presence and enumeration of faecal indicator bacteria in groundwater. We hypothesise, however, that ...
Proximity Density Assessment and Characterization of Water and Sanitation Facilities in the Informal Settlements of Kisumu City: Implications for Public Health Planning
(University of Nairobi, 2020)
Access to water and sanitation remain a challenge in many developing countries, especially in pro-poor urban informal settlements where socioeconomic livelihoods are generally low. The aim of this study was to characterise ...
Validation of a Quantitative Proton Nuclear Magnetic Resonance Spectroscopic Screening Method for Coffee Quality and Authenticity (NMR Coffee Screener)
(University of Nairobi, 2020)
Monitoring coffee quality as a means of detecting and preventing economically motivated fraud is an important aspect of international commerce today. Therefore, there is a compelling need for rapid high throughput validated ...

(University of Nairobi, 2020)
Background: Anaerobic degradation entails the conversion of substrate organic
matter to biogas. A wide variety of substrate has been employed. The
biochemical methane potential of twenty market wastes was investigated ...
Expansions of chemosensory gene orthologs among selected tsetse fly species and their expressions in Glossina morsitans morsitans tsetse fly
(University of Nairobi, 2020)
Tsetse fly exhibit species-specific olfactory uniqueness potentially underpinned by differences in their chemosensory protein repertoire. We assessed 1) expansions of chemosensory protein orthologs in Glossina morsitans ...
A microsporidian impairs Plasmodium falciparum transmission in Anopheles arabiensis mosquitoes
(University of Nairobi, 2020)
A possible malaria control approach involves the dissemination in mosquitoes of inherited symbiotic microbes to block Plasmodium transmission. However, in the Anopheles gambiae complex, the primary African vectors of ...
Characterization of Water Hyacinth Cellulose-g-poly (Ammonium Acrylate-co-acrylic Acid)/nano-hydroxyapatite Polymer Hydrogel Composite for Potential Agricultural Application
(University of Nairobi, 2020)
Polymer nano-composite was prepared by grafting partially neutralized acrylic acid onto swollen cellulose iso-lated from water hyacinth in the presence of nano-hydroxyapatite (nano-HA) usingN,N-methylene-bis-acrylamide ...

Prevalence of tick-transmitted pathogens in cattle reveals that Theileria parva, Babesia bigemina and Anaplasma marginale are endemic in Burundi
(Springer, 2021-01-05)
Background
Tick-borne diseases (TBDs) constitute a major constraint for livestock development in sub-Saharan Africa, with East Coast fever (ECF) being the most devastating TBD of cattle. However, in Burundi, detailed ...
