Phylogenetic Diversity, Antibiotic Resistance, and Virulence of Strains from Urinary Tract Infections in Algeria.

Urinary tract infections (UTIs) caused by represent a significant public health concern due to the high virulence and antimicrobial resistance exhibited by these pathogens. This study aimed to analyze the phylogenetic diversity and antibiotic resistance profiles of Uropathogenic (UPEC) strains isolated from UTI patients in Algeria, focusing on virulence factors such as extended β-lactamase (ESBL) production, biofilm formation, and hemolytic activity. Phylogenetic grouping of 86 clinical imipenem resistant isolates showed the prevalence of group B2 (48.
