Abstract
Urinary tract infections (UTIs) are currently one of the most important medical practice visits. The spread of antibiotic-resistant bacteria in the community complicates the therapeutic management. The aim of this study is to investigate the bacteria associated with community acquired urinary tract infections (CA-UTIs) and the antibiotic resistance pattern of bacterial isolates during 2021 in Algiers, northern Algeria. A total of 548 urine samples from patients with CA-UTIs symptoms were analyzed. Pure bacterial isolates were identified using morphological and biochemical characteristics, and subjected to antibiogram evaluation using the disk diffusion method. A total 133 out of 548 patients (24.27%) had positive CA-UTIs, mainly affecting women (84.21%). A percentage of 87.22% of isolates were identified as Enterobacteriaceae, which were represented mostly by Escherichia coli (76 isolates), Klebsiella pneumoniae (13 isolates), and Proteus mirabilis (13 isolates). A number of 125 isolates (93.98%) were resistant to at least one antibiotic tested. The results showed the highest antibiotic resistance to ampicillin (92.24%) and amoxicillinclavulanic acid (91.37%), and revealed the most sensitivity to cefotaxime and nitrofurantoin (95.69%) and colistin (93.11%). The results of this study revealed high concerns about CA-UTIs caused by multidrug-resistant Enterobacteriaceae.
