Extended-spectrum Beta-lactamase- Producing Escherichia coli and Klebsiella pneumoniae Clinical Isolates in Sudanese Hospitals: Analytical Comparative Cross Sectional Study

Abstract

Extended-spectrum – beta lactamases (ESBLs) are increasingly detected globally among Escherichia coli (E.Coli) and Klebsiella pneumoniae (K.pneumoniae). This study was designed to determine the prevalence and antibiogram of ESBLs produced by E.coli and K.pneumoniae clinical isolates obtained from various clinical specimens through different hospitals in Khartoum state -Sudan. An analytical comparative cross-sectional study was conducted. Identification of the isolates was done by using conventional biochemical methods ESBL screening, confirmatory according to CLSI guidelines. Statistical analysis was performed using the Statistical Package of Social Sciences (SPSS). Total of 368 isolates of Escherichia coli(n=216) and Klebsiella pneumonia (n=152) isolates were processed , Overall ESBL phenotype prevalence was 36.7 %, 40.1% and 34.2% of K. Pneumoniae and E. coli isolates respectively were confirmed to be ESBL phenotype. In this study, meropenem and imipenem were the most active antimicrobial agents against them. This study was indicated high prevalence of ESBL phenotype in Khartoum-state, with multidrug resistant trend, there is a need for longitudinal and nationwide surveillance as this help in tracking antibiotic resistant and regulating antibiotic policy.
