My Msc thesis was on Characterization of Escherichia coli and Klebsiella pneumoniae isolated from neonates in a nursery ward using DNA probes, plasmid profiles, and antimicrobial susceptibility patterns. The plasmid profiles of the enteropathegenic Escherichia coli strains were similar and the enteropathogenic gene was located on a specific plasmid.Currently i am working on the prevalence and economic cost of aflatoxins in the Kenyan dairy value chain for my PhD thesis.
