Molecular Detection Of Some Capsulargenes Of Klebsiella Pneumoniae Isolated From Clinical Samples

Klebsiella pneumoniae is an opportunistic pathogen that has been implicated as one of commonest cause hospital and community acquired infections.The capsule important virulence factor, involved in pathogenic mechanisms.So, this study aimed to isolateKlebsiella from different clinical samples patients Al-Diwaniyah teaching determine some factors (capsulegenes)that used for serotyping isolates. The extended fromAugust  November 2020.A total 31 isolates 80 identified by traditional biochemical tests ,Vitek system 16SrRNA gene.The existenceof three genes from7tested capsulargenes wasdetectedby Polymerase chain reaction.The commonness serotype were k2,k54,k57 where K2 detected 4 (12.9 %), K54 12 (38.7 %),k57 (12.9).But, the other capsular polysaccaride k1,k3,k5,k20not detectedin all study.
