Profil bactériologique et résistance aux antibiotiques des bactéries responsables des infections urinaires

Abstract

Urinary tract infections represent a particularly important health problem and occupy a major place in infectious pathology. The cytobacteriological examination of urine allowed us to identify the germs responsible for urinary tract infections and to determine their profile of sensitivity to antibiotics. This study was carried out at the level of the medical analysis laboratory ECH CHIFAA - Chlef. In the bacteriology department during the month of May 2022. Our study focused on 97 positive samples, which went through several stages of identification for the search for the infectious agent: macroscopic and microscopic examination, culture, the different colorations, the biochemical tests. Thus, each bacterium incriminated had benefited from an antibiotic sensitivity study. By taking into consideration several parameters including: sex, age, bacteriological profile and resistance to antibiotics. The majority of these infections are due to Enterobacteriaceae with a percentage of 85%, of which Escherichia coli is the most commonly observed bacterium. The relationship between sex and these infections shows a predominance of the female sex with 62%. The study of the resistance of these germs to antibiotics shows a strong resistance of Enterobacteriaceae to Ampicillin and Amoxicillin. Pseudomonas showed strong resistance to Ampicillin, Amoxicillin, Nutrofurantoin, and Cephalotin. Furthermore, we note a high sensitivity of the germs studied to Tobramicin and Amikacin.
