Abstract Background Rotavirus, norovirus, adenovirus (type 40/41) and astrovirus are the most significant viral etiological agents of acute gastroenteritis in young children globally. Kenya introduced rotavirus vaccine into her National Immunization Program July 2014, which has led to a decline prevalence rotavirus. We sought assess impact vaccination on epidemiological trends other diarrhea-associated enteric viruses across different regions Kenya. Methodology Using conventional multiplex...

Abstract Aim This study aimed to develop a multiplex PCR assay for simultaneous detection of major Gram-negative etiologies septicemia and evaluate its performance. Methods Multiplex (mPCR) assays were developed targeting 11 bacterial strains. Species-specific primers confirmed using known clinical isolates standard Gradient was performed on each primer against target gene determine optimal amplification condition. The minimum detectable DNA concentration the two evaluated by adjusting 100...

When properly used and adequately maintained, a biological safety cabinet (BSC) provides protection to the laboratory worker, products, environment. Knowledge about proper use of BSC is therefore important. This study evaluated usage knowledge practices effect prior experience on training outcomes. Thirteen participants randomly selected from research centers were through structured questionnaire covering biosafety considerations involved in using as per World Health Organization’s...

Water, sanitation and hygiene (WASH) child health interventions are proven simple cost-effective strategies for preventing diarrhea minimizing excess mortality. Individually, they able to prevent though sub-optimally, their effectiveness when combined may be higher. This study examined the effect of integrated WASH maternal (MCH) on prevalence diarrhea, in a resource-limited setting Kenya.
