A total of 198 samples from internal organs and fecal matter of diseased and healthy ducks breeds were collected from farms and backyards in Dakahlia governorate (Egypt). The samples were examined bacteriologically and by PCR. Sensitivity, PCR and pathogencity tests were applied. Fifteen samples (7.58%) were found to be positive for Salmonellosis and four strains were detected serologically (S. Infantis, S.Enteritidis, S. Inganda and S. Larochelle) also Untyped Salmonella strain was detected. Six samples (3.09 %) were found to be positive for Pasteurella multocida by bacteriological and PCR examinations.
