Identification of Klebsiella pneumoniae and Klebsiella oxytoca in urine specimens from a laboratory in Karachi

Abstract

This study aims to identify Klebsiella pneumoniae and Klebsiella oxytoca in urine specimens. The study was carried out in the Dr. Essa Laboratory & Diagnostic Centre, Karachi, Pakistan from January 2014 to December 2014. A total number of 470 urine samples from patients of January 2014 to December 2014 were included in the study from all branches of Dr. Essa Laboratory & Diagnostic Centre. Isolates of K. pneumoniae and K. oxytoca were identified by their morphological and biochemical characteristics. All isolates were subjected to antibiotic sensitivity testing by modified Kirby bauer disc diffusion method. The number of K. pneumoniae isolates was 240 while K. oxytoca isolates was 230 from 470 urine samples. Majority of the strains were sensitive to Amikacin. In conclusion, the present study exposed the K. pneumoniae and K. oxytoca strains in patients and their tendency towards antibiotic resistance. The objective of the present study was to know the antibiotic sensitivity pattern of K. pneumoniae and K. oxytoca strains isolated from urine samples, where we found most of the strains isolated were sensitive to Amikacin and Imipenem.
