Prevalence and diversity of Staphylococcus aureus in the Zambian dairy value chain: A public health concern.

Staphylococcus aureus is an important opportunistic pathogen of both humans and animals. It can cause several diseases, including mastitis, as well as food poisoning by production of heat-stable enterotoxins in food. The aim of this study was to determine the prevalence of S.

Clonal relationship between multidrug-resistant Escherichia coli ST69 from poultry and humans in Lusaka, Zambia.

Multidrug-resistant (MDR) Escherichia coli in food animals such as chickens is an emerging public health concern in Zambia. Additionally, the country's high demand for poultry products necessitates further investigation into the link between poultry and human MDR E. coli.

Novel chromosomal insertions of ISEcp1-bla and diverse antimicrobial resistance genes in Zambian clinical isolates of Enterobacter cloacae and Escherichia coli.

Background: The epidemiology of extended-spectrum β-lactamases (ESBLs) has undergone dramatic changes, with CTX-M-type enzymes prevailing over other types. bla genes, encoding CTX-M-type ESBLs, are usually found on plasmids, but chromosomal location is becoming common. Given that bla-harboring strains often exhibit multidrug resistance (MDR), it is important to investigate the association between chromosomally integrated bla and the presence of additional antimicrobial resistance (AMR) genes, and to identify other relevant genetic elements.
