Isolation of Pasteurella multocida was attempted from the heart blood, spleen, liver and lung collected from turkeys (4 No,s) and chicken (4 No,s) suspected to have died of avian pasteurellosis. A total of eight P. multocida isolates were isolated and identified on the basis of biochemical characteristics, pathogenicity studies in mice and PM-PCR. The In vitro antibiotic sensitivity test of the...

A 5' Taq nuclease assay utilising minor groove binder technology and targeting the 16S rRNA gene was designed to detect Pasteurella multocida (the causative agent of fowl cholera) in swabs collected from poultry. The assay was first evaluated using pure cultures. The assay correctly identified four P. multocida taxonomic type strains, 18 P. multocida serovar reference strains and 40 Australian ...

In the spring of 1975, many species of waterfowl and common crows (Corvus brachyrhynchos) were found dead in Phelps County, Nebraska. About 25,000 water fowl and at least 3,000 crows died in the epornitic. Few waterfowl were seen dying, but the crows experienced a chronic illness during which they became debilitated and were lethargic and dyspneic. Gross and microscopic lesions in the waterfowl...

Fowl cholera, also called as avian cholera or avian pasteurellosis, is a contagious and economically important disease of poultry particularly chicken, turkeys, ducks and geese (Rimler and Glisson, 1997). It is caused by Pasteurella multocida,a small gram-negative bacteria, which inhabits the upper respiratory tract of the many avian species as commensal (Rimler and Glisson, 1997). It has been ...

In order to show the type and severity of gross and histopathologic lesions induce by vaccinal strain (serotype A1) of Pateurella mulocida, ten four-week-old SPF chickens were inoculated intramuscularly with 75 cfu of ( 0.5 ml of 10-7 dilution) bacterium. All birds died in less than 16 hours. No prominent gross lesions were observed in different organs. In microscopic examination, the most comm...

FowL PLAGUE is a devastating disease of poultry which was first described in the form of outbreaks in Italy in the last two decades of the nineteenth century.1 Until then no clear aetiological distinction had been made between it and chicken cholera, and only after Perroncito2 in 1878 and Pasteur" in 1880 had turned their attention to chicken cholera did the difference in clinical manifestation...
