RESISTANCE ON ANTIBIOTIC DRUGS AND INCIDENCE OF SOME BACTERIA SPECIES IN URINARY TRACT INFECTIONS
Objectives. The aim of our study was to determine the urinary infection incidence caused by different microbial species and the sensitivity to the different antibiotics classes.
Materials and methods. We observed a lot of 638 patients which were hospitalized in Gerota Hospital from Bucharest during six weeks for different pathologies (gastroenteritis, cardiovascular disease, pneumonitis, and urinary tract infections).
Results. From the total number of patients, 100 were done positive for urinary tract infections. The predominant species was E. coli (65%) followed by Enterococcus species (15%), Proteus species (10%), Enterobacter species (6%), Pseudomonas aeruginosa (3%) and Staphylococcus aureus (1%). The incidence E. coli species was 57% for women and 23% for men. Six strains were susceptibility only to imipenen and resistant to all antibiotics used (four E. coli strains and two Enterobacter strains). Five of these were from men and one from a woman. Incidence of antibiotic drugs resistance was 45% for gentamicin, 43% for cefaclor, 43% for tetracycline, 21.5% for ciprofloxacin, and 26% for amoxicillin and clavulanic acid for E. coli strains.
Conclusion. Most of identified strains belong to Escherichia coli species and have a great resistance to antibiotic drugs.
