Abstract

The aim of this study was to investigate the role of Klebsiella pneumoniae bacterial infection in causing mortalities in broiler chicks. Trials were carried out to isolate and identify Klebsiella Pneumoniae Spp from 1-7day-old broiler chicks suffering from mortalities during first week of age. Followed by Antimicrobial sensitivity test. Results of isolation and identification using biochemical tests followed by Duplex polymerase chain reaction technique confirmed that  21% of the broiler chicks flocks were positive to Klebsiella pneumoniae Spp. Mortalities ratio in the investigated flocks were (0.3%-5%) at the first week .Using Antibiotic sensitivity test, Thiamphenicol (Tersan ®20%) was found to be best effective drug to overcome the infection with Klebsiella pneumoniae Spp. in broiler chicks. Further studies are needed to delineate that presence of Klebsiella Pneumoniae Spp is linked to clinical disease and mortality in baby chicks.
