Community acquired urinary tract infections (CAUTI) with special reference to antibiogram of Escherichia coli and Klebsiella species

Escherichia coli and Klebsiella species are the most important uropathogens. The present study was undertaken to isolate uropathogens causing community acquired urinary tract infections (CAUTIs) and their antibiogram.

A total of 755 clean voided mid-stream urine samples were collected and processed. All the specimens were collected from patients attending various OPDs of our hospital. The specimens were cultured and the isolates were identified using standard microbiological techniques. The antibiotic susceptibility was determined by disc diffusion technique. Simple percentage method was used in analyzing data.

From 755 urine specimens, 197 urine specimens yielded significant bacterial growth accounting for 26.09%. Females (75.13%) are more commonly affected than males (24.87%).

E.coli119 (60.40%) was the most frequent organism isolated followed by Klebsiella species(24.87%). Klebsiella species showed high degree of resistance towards the antibiotics tested.

High isolation rate was observed among young females in reproductive age groups. E. coli was the predominant bacteria causing UTI followed by Klebsiella species. Very high resistance rates were observed towards commonly used antibiotics in community.
