Study of Antibiotic Resistant Pattern of Escherichia coli Isolated from Urinary Tract Infections of Patients of Bangladesh

Urinary tract infections (UTIs) are serious health affecting problems worldwide. Urinary tract infection (UTI) can be caused by a lot of bacteria. Among them, E. coli is one of the main causes of both nosocomial and community acquired Urinary tract infections in humans. Drug resistance of E. coli is becoming alarming with the passage of time worldwide in general and in third world countries in particular. The study was intended to collect and analyze the samples from the patients suffering from Urinary tract infection of two medical of southern region of Bangladesh to reveal the antibiotic resistance pattern of E. coli responsible for Urinary tract infection. 50 samples from each hospital were taken. 36 and 41 samples respectively were identified as E. coli. Antibiotic sensitivity testing was done on Mueller-Hinton agar by Kirby–Bauer disc diffusion method. All samples exhibited a different percentage of resistance where ciprofloxacin was showed evidence of higher resistance rate, which was 63.88% and 70.73% respectively. Higher resistance (63% & 75%) against Ampicillin was also found in patients of both medical. On the other hand, 16% resistance against ceftriaxone and 23.53% resistance against cefotaxime suggesting, they were comparatively more effective.
