Abstract
Pasteurella multocida is considered to be an important cause of ovine pneumonia and results causes considerable economic losses in Iran. Ribotyping PCR (Ribo-PCR) was used for investigating the diversity of ovine and caprine P.multocida. A total of 120 swab tonsil and nasal samples were obtained from sheep and goats. They were analyzed by biochemical tests and Ribo-PCR 16S-23S ribosomal RNA genes. Twenty samples representing Pasteurella phenotypes by Entero rapid kit and 17 out of 20 isolates were identified as P.multocida. Capsular type A was dominant among the isolates and was variable than serogroup D. Nine isolates including JF694004.1 and 8 isolates including JF681973.1 showed 100% and 94% similarity, respectively. Two minor cluster I and II was obtained with no significant diversity among the isolates. Cluster II was divided in four sub cluster including IIa, IIb, IIc and IId. Molecular approaches such as Ribo-PCR are necessary for determining and characterizing the diversity of P. multocida and understanding their interactions with host. The study has been the sensitive levels of Ribo-PCR in epidemiological studies of pasteurellosis, however, correlation among diversity of isolates and host origin is not fully understood.
