Abstract
From the total 121,294 clinical materials submitted to the Department of Laboratory Medicine of "C" hospital from December 1, 2004 to November 30, 2006, 3,408 Pseudomonas spp. were isolated. The isolation frequencies of Pseudomonas spp. were as follows, P. aeruginosa 95.5%, P. putida 2.5%, P. fluorescens 0.8%, along with low frequencies of P. luteola, P. alcaligenes, P. stutzeri, P. oryzihabitants, P. mendocina and unidentified Pseudomonas species. The isolation rates of Pseudomonas spp. according to season and sex were evenly distributed. The isolated frequency of Pseudomonas spp. in male was two times higher than that of in female showing significantly more male patients in surgical areas and more female patients in internal areas (p<0.001). In monthly analysis, Pseudomonas spp. were the most frequently isolated in July (10.4%), but lowest in February (5.6%). Half of Pseudomonas spp. were isolated from sputum (48.2%). In the susceptibility analysis of Pseudomonas spp. by VITEK II AST cards, the Pseudomonas spp showing higher susceptibility against antimicrobial agents were piperacillin/tazobactam (82.7%) in P. aeruginosa; amikacin (84.7%), colistin (83.3%) in P. putida; and amikacin (96.3%), cefepime (87.5%), ceftazidime (87.5%) ciprofloxacin (92.3%), colistin (88.5%) gentamicin (96.2%), isepamicin (96,1%), meropenem (92.3%), netilmicin (96.0%), piperacillin/ tazobactam (95.4%) and tobramycin (92.6%) in P. fluorescens.
