Study of antibiotic sensitivity pattern in urinary tract infection at a tertiary hospital.

ABSTRACT

This study was conducted in a tertiary hospital at Bareilly, Uttar Pradesh between Aug 2009 and July 2010 to check the changing pattern of antibiotic sensitivity among uropathogens causing urinary tract infections (UTI). A total of 170 urine culture sensitivity reports were analyzed. The predominant growth of single bacteria was seen in 143 (84.12%) samples. The most common organisms isolated were Escherichia coli, klebsiella, pseudomonas, and Staphylococcus aureus. (These represented 64.33%, 92; 20.3%, 29; 9.1%, 13 and 6.30%, 9 of isolates respectively). More than 80% of the isolates were sensitive to amikacin and nitrofurantoin, while more than 70% were sensitive to norfloxacin, ciprofloxacin and levofloxacin. Very high rate of resistance was seen against cotrimoxazole (81.82%), amoxicillin (77.42%) and amoxi-clav (64.34%). E. coli showed high sensitivity to Amikacin 98.91% (91), Nitrofurantoin 93.48% (86). 75% of E. coli isolates were sensitive to minocycline, showing a good utility of this drug for the treatment of outdoor patients with urinary tract infections.
