Abstract:

 Background: The emergence of multi-drug resistant (MDR) Salmonella Typhi poses a major challenge in the treatment of typhoid fever using commonly available antibiotics. However, in many rural and semi-urban communities of low- and middle-income countries (LMICs), routine surveillance for MDR S. Typhi is scarcely undertaken. The aim of this study is to determine the prevalence of β-lactamase genes in MDR S. Typhi isolated from patients in nine secondary healthcare facilities in Benue south senatorial district, northcentral Nigeria.

Abstract:

 Background: Salmonella enterica serovar Typhi is the causative agent of typhoid fever, a major public health concern in Nigeria and other low-resource settings. The emergence of antimicrobial resistance (AMR), often plasmid-mediated, poses a serious challenge to treatment. Local surveillance data on resistance and plasmid carriage are critical for guiding effective interventions. This study investigated the antimicrobial susceptibility and plasmid profiles of clinical Salmonella Typhi isolates from stool samples in Sagamu, southwest Nigeria.
