Abstract

Background: Klebsiella pneumoniae is a pathogenic bacteria that can form biofilms on abiotic and biotic surfaces. The constraints of the therapeutic choices against K. pneumoniae arise from its innate capacity to develop biofilm and harboring determinants of multidrug resistance. Objective: The current study aimed to assess the prevalence of some fimbrial genes (type 1 and type 3) of K. pneumoniae strains in community-acquired infections obtained from various clinical sources on their ability to produce biofilm. Methods: A total of 256 samples (106 male and 150 females) were taken from various clinical sources including Urine, wound swabs, sputum, burn swabs, bronchial wash, diabetic foot ulcer, and higher vaginal swabs) from outpatients in Kirkuk City hospitals. The isolates were identified on the Blood agar, MacConkey agar and Eosin Methylene Blue agar based on the cultural, morphological, in addition to biochemical assays, and confirmed using the automated VITEK 2 system. The Microtiter plate (MTP) method was employed to detect Biofilm formation. Subsequently, a polymerase chain reaction was performed to determine the presence of the T1 fim and mrkD genes. Result: Out of 256 only 38 (14.8%) isolates belonged to Klebsiella pneumoniae. Of all isolates, 38(100%) were biofilm producers. The PCR results revealed that all 38 isolates showed positive (100%) for T1 fim and 37 isolates (97.4%) for mrkD.
