Analysis of Antibiotic Resistance in Escherichia Coli Strains, Isolated from Urine Cultures in Laboratories of Kashmar, Iran

Journal Authors: 


Background and Aims: Resistance of bacteria, causing urinary tract infections, is increasing with indiscriminate prescription of antibiotics. Such resistance has even emerged in stronger antibiotics. This study was performed to evaluate the antibiotic resistance pattern in Escherichia coli (E coli) isolated in laboratories of Kashmar, with particular attention to nalidixic acid (NA) and co-trimoxazole (SXT).

Materials and Methods: A total of 50 samples of positive E coli strains were collected in Kashmar laboratories and confirmed by the standard biochemical method (Gallery). Evaluation of antibiotic susceptibility and resistance was performed by Mueller-Hinton agar for disk diffusion.

Results: Out of 50 samples, resistance to co-trimoxazole and nalidixic disks was higher, considering the curves.

Conclusion: The obtained curves related to the studied antibiotics show that in this region, due to indiscriminate use of antibiotics and lack of restrictions in using antibiotics, resistance of some bacteria has increased.
