Abstract
In a surveillance targeting different birds communities, 237 cloacal swabs and intestinal samples from 39 different species of wild birds from different sources were examined bacteriologically for Salmonella. 32 samples were positive for Salmonella spp., with an incidence of 13.5%. Migratory birds had the highest incidence with a 28.26 percentage. The incidence in free living birds was somewhat lower (18.57%). While the Zoo birds had the lowest incidence (4.96%). Serotyping of the isolates revealed 6 different serotypes [Salmonella Typhimurium, Salmonella Rissen, Salmonella Regent, Salmonella Doncaster, Salmonella Curacao, Salmonella IIIb group (O65) and untyped Salmonella] . Salmonella Typhimurium represented 40.63% of the isolated serotypes. In vitro antibiogram test was performed for the 2 strains isolated from Zoo birds. Salmonella Curacao was sensitive to most of the utilized antimicrobial agents. However Salmonella IIIb group (O65) had surprising results as it was resistant to 10 out of the 11 applied antibiotics. 26 serum samples were examined by tube agglutination test using S. Typhimurium antigen where 15 samples were positive. PCR technique was done on 30 samples to assess the power of two different isolation enrichments[Rappaport vassiliadis (RV) and buffered peptone water (BPW)] in comparison to that of the standard microbioligical techniques (SMT). The detection percentages of RV-PCR, BPW-PCR and SMT was 66.7%, 46.7%, and 13.3%, respectively.
