Pasteurella multocida is known to cause duck cholera leading to high morbidities and mortalities resulting in huge economic losses. Acute duck cholera is characterized by sever watery diarrhea, anorexia, respiratory manifestations and septicemia, while chronic one leads to localization of the organism in certain organs. This study was undertaken to investigate the prevalence of Pasteurella multocida in ducks in Egypt. Expression of some virulent-genes in the isolated Pasteurella multocida serotypes were examined using the polymerase chain reaction. Finally, antibiotic sensitivity testing of the identified Pasteurella multocida serotypes was also done. Pasteurella multocida could be isolated from 60% of the ducks showing respiratory manifestations and watery diarrhea. 69.8% of the isolated Pasteurella multocida strains followed capsular type A serotype, 20.9% of capsular type D and 9.3% as untypable. Lungs and air sacs had the highest incidence of Pasteurella multocida followed by liver, heart and spleen. Pasteurella multocida serogroups highly expressed virulence-attributes responsible for diarrhea. Pasteurella multocida serogroups showed marked resistance towards some used antibiotics in Egypt.
