Antibiotic resistance pattern of urinary isolates in a Rural Medical College of Maharashtra

To determine resistance pattern of urinary isolates in a rural medical college of Maharashtra.

Urine samples were collected using midstream clean catch method in clinically diagnosed UTI cases from august 2016 to February 2017. A total of 320 samples were analyzed under supervision of qualified microbiologist. Antibiotic sensitivity of isolated microorganisms were tested for commonly used antibiotics by Kirby bauer technique.

Out of 320 samples 200 were positive. The pathogens isolated were E.coli 60 (30%), Pseudomonas 45 (22.5%), Methicillin resistant Staphylococcus aureus 35 (17.5%) & Klebsiella 30 (15%). E.coli being the most common isolate. The isolates showed high degree resistance for Amoxycillin & Cotrimoxazole.

62.5% of samples showed significant growth. Moderate yield suggest moderate clinical correlations in suspected cases of UTI. E.coli showed low level resistance to Nitrofurantoin (1.67%), Amikacin (3.34%), Norfloxacin (13.3%) & high degree resistance to Cotrimoxazole (63.34%), Piperacillin + Tazobactam (50%), fluoroquinolones (27.04%). It's very clear from the study E.coli is the MOC infecting uropathogen & developing resistance against the commonly used antibiotics.
