Abstract :

To determine seroprevalence of Salmonellosis among Pigeon and its surrounding environment in Egypt, isolation of Salmonella species from collected samples and serotyping of isolated stains. Materials and Methods: In this study, a total of 400 samples were collected from squabs and adult pigeon represented in cloacal swabs from diseases, liver, intestine and lymph node from apparent healthy, slaughtered and freshly dead one. Screening of pigeon environment was done by collection of 150 environmental samples. Bacteriological and serological examination of isolated salmonella species from positive samples were carried out. Results: The prevalence rate of Salmonella isolates for squabs, pigeon and environmental samples was 5%, 3.5% and 4.6% respectively. The isolated serotypes recovered from squabs were 4 isolates of S. Typhimurium, and 2 isolates from each of S.Enteritidis, S.Agona and S.Montevideo. While in adults were S.Typhimurium and S.Enteritidis (3 isolates from each) and one isolates from S.agona. serotyping result of environmental samples revealed 3 serotypes of S.Typhimurium, S.Agona and S.Virginia.Conclusion: Seroprevalence of Salmonella species is higher in squabs than that occur in adult with a higher rate in diseased followed by freshly dead and finally by apparently healthy slaughtered birds. Pigeon surrounding environment was screened for Salmonella species and isolated with a percent 4.7% and serotyped as S.Typhimurium, S.Agona and S.Virginia.
