Abstract
Pasteurella multocida is a gram negative bacterium causing respiratory diseases in many birds including ducks resulting in great morbidity and mortality rates among them. Seventy five samples were collected from air sacs, lungs, livers, hearts and spleens were collected from different duck flocks which selected randomly and hade respiratory manifestations and diarrhea. All samples subjected to bacteriological examination for the presence of Pasteurella multocida (P. multocida). The results showed that Pasteurella multocida was isolated in a prevalence rate of as 13%. All isolates were identified by vitek 2 system. The virulence genes of two random isolates of Pasteurella multocida (toxA , tbpA and pfhA ) were detected by PCR. The results of antibiotic sensitivity test proved that the isolates were resistant to Cefalexin, Cefpodoxime, Ceftiofur, Amikacin, Nitrofurantoin, Trimethoprim, Rifampicin and Tetracycline. While the isolates were sensitive to Ampicillin, Amoxicillin/clavunic acid, Piperacillin, Cefpirome, Imipenen and Trimethoprim/Sulfamethoxazle. The three examined virulence genes were detected in both samples.
