عزل بكتريا Klebsiella planticola من اصابات سريرية في العراق

Abstract

Out of 400 different clinical samples, fifty SiX (14%) isolates of Klebsiella were identified. of it, 19 isolates (33. 93%) were from wound and burn infections, 17 isolates (30.36%) were from urinary tract infections, 11 isolates (19.64%) were from respiratory tract infections an 9 isolates (16.07%) were from bacteremia cases. Fifty isolates (89.28 %) were found to be K. pneumoniae (49 isolates were K. pneumoniae pneumoniae and one isolare was K.pneumoniae ozaenae), 5 isolates (8.93%) were K.oxytoca, and one isolate ( 1.79 %) was K. planticola which isolate as first time in Iraq. The result showed that K. planticola had the ability to express similar virulence factor (capsule. fimbriae type I, type III and siderophore production) as the other species of Klebsiella. Sensitivity test against 25 antibiotics was done for all the isolates. It was found that the most effective antibiotics against Klebsiella were amikacin (94.67%), norfloxacin (91.07%), ciprofloxacin (85.71%) and amoxiclave (71.4%). The percentages of sensitivity for the extended - spectrum cephalosporines were 57.14%, 53.57%, 50%, and 48.2% for cefotaxime, cefixime, ceftazidime and ceftriaxone respectively. Nevertheless, none of the isolates revealed any sensitivity (0 %) to ampicillin, ampiclox, amoxicillin, carbenicillin and rifampicin .K.planticola reveled resistante to nine antibiotics (ampicillin, ampiclox, amoxicillin, carbenicillin, cephalothen, cephalexen, streptomycin, co-trimoxazol and rifampicin).
