Abstract
Camels were imported to Egypt in large numbers to be slaughtered for meat consumption.The current work was carried out to clarify the role of camels and attached ticksin transmission of emerging zoonotic diseases. For this purpose,a total of 406 adult ticks as well as blood and fecal samples were gathered from 206 apparently healthy slaughtered dromedary camels (181 imported and 25 local camels) in Bassitin abattoir, Cairo. In addition to75blood and 50 stool samples from human contacts. The laboratory investigation of obtained samples revealed that Salmonella serovars were recovered from 17 (8.3%) camel fecal samples while allhuman stool specimens were negative. All Salmonella isolates carried invA gene whereas stn gene was expressed from 12 isolates mainly exotic ones. Twenty one (5.2%) and fifteen (3.7%) ticks were positive by PCR for C.burnetii and Francisella spp.respectively but blood and fecesof camels including those carrying positive C.burnetii and Francisellaspp. ticks yielded negative results for both pathogens. Moreover, F.tularensis was not detected among positive Francisellaspp. ticks. On the other hand, C.burnetii and F.tularensis antibodies could be found in camel butchers and slaughterhouse workerswith seroprevalence rate 18.7% and 9.3% respectively.In conclusion, this study highlighted that camels could play a critical role in transmission of emerging tick borne diseases such as Q fever and Francisella infection as well as exotic Salmonellastrains across geographical boundaries
