Abstract
This work was carried out to study the zoonotic importance of Salmonella spp. as a potential foodborne pathogen. To achieve this purpose, the following points were inducted:
7.1 Identification of different Salmonella serovars from the examined samples
• Chicken meat and chicken organs (152, each), 76 cloacal swabs, 20 cutting surface swabs from pluck shop outlets, 140 egg swabs (outer egg shell and inner egg content, 70, each) and 150 human samples were collected from in Abo-Hammad and Zagazig cities, Sharkia Governorate.
• Bacteriological examination revealed that 129 (18.7%) of the samples under investigation were suspected to be contaminated with Salmonella species.
• Molecular amplification of the invA gene revealed that 29 (4.2%) were identified as Salmonella species.
7.2 Occurrence of Salmonella spp. in chicken and eggs
• The overall isolation rate of Salmonella spp. from the examined chicken meat samples was 5.9% (9/152), with insignificant different isolation rate of Salmonella spp. from breast (6.6%) and thigh muscles (5.2%).
• The overall isolation rate of Salmonella spp. from chicken organs was 2.6%, it was isolated from liver and heart samples with the same frequency (2.6%).
