The serological survey of salmonella infection in camels (camelus dromedarius) of Najafabad, Iran

Salmonellosis is a zoonotic disease and is produced by Salmonella spp.. The signs of the disease in animals are abortion، gatsroenteritis and diarrhea. The aim of this study was to determine the serological prevalence of salmonellosis in camels of Najafabad by S. typhimurium، S. paratyphi A، C and S. enteritidis D in Camelus dromedarius in Najafabad slaughter house. To do this، 384 blood samples were collected and were tested to detect anti-Salmonella groups A، B، C and D antibodies. Serological examinations by agar gel immunodiffugen test showed only three positive samples. Two samples were positive for group B salmonella (aged 1-2 years) and one sample was positive for group C (aged 5-7 years). It could be concluded that camels might be a risk factor for spreading of salmonella in this area but it is not so serious. However it should be considered in further investigations and public health programs. Finally، it is worth mentioning that because there is no strict surveillance in our eastern borders، the hazard will be serious in future، as well.
