Isolation of Citrobacters in various infections and their antimicrobial sensitivity rates

WOS: 000290955200017
The samples for culture from the patients admitted to Konya Research and Education Hospital between January 2009 and July 2010 were investigated. The obtained Citrobacter strains were studied for antimicrobial sensitivity rates and their distribution ratesto the clinics. The samples obtained were inoculated onto related culture media. Aseptic body samples were incubated at 37 degrees C into bottles of BACTEC 9120 blood culture system. For the identification and antimicrobial sensitivities of yielding bacteria, panels of Phoenix-100 automized identification device were used. Mean age rate of patients in whom Citrobacter strains were determined was 41.29 +/- 4.345. Of all samples with Citrobacter strains, 48% were isolated from urine, 29% from surgical wounds, 11% from sputum, 2% from peritoneal fluid, and 2% from vaginal samples. Of total 52 Citrobacter strains, the species level distribution was 46% C. freundii, 21% C. youngae, 15% C. koseri, 10% C. braakii, 6% C. farmeri and 2% C. wermanii. The distribution of samples with Citrobacter strains to the clinics were 29% adult intensive care unit (ICU), 21% pediatric, 11% general surgery, 10% in neonatal ICU, 10% plastic surgery, 7% urology, 6% burn unit, and 6% nephrology department. The most sensitive antimicrobial agents to Citobacter strains were amikacin (100%), meropenem (100%), imipenem (96%) and piperacillin/tazobactam (96%).
