This study was conducted to diagnose the seroprevalence of Listeriosis, Brucellosis, and Toxoplasmosis in camels from Kirkuk province in Iraq. Seventy-six serum samples were randomly collected and analyzed from camels from April to September 2018. Three serological diagnostic methods were used; Osebold agglutination test (OAT), Serum tube agglutination test (SAT) and Sabin- Feldman dye test (SFDT). From all serum samples that were collected, 42(55.26%) showed infections with Listeria, Brucella, and Toxoplasma as following 15(19.7%), 7(9.2%), and 20(26.3%) respectively. Additionally, the study revealed a highly significant relationship between aborted camels and their infection with Brucellosis and Toxoplasmosis (58.3%). In contrast, infections with these pathogens have no significant relationship with the sex and age of the camels. Risk factors of abortion were related to the high prevalence of Brucellosis and Toxoplasmosis in camels' herds. Furthermore, this study found out that the camels in Kirkuk city might be the source of these infectious agents and disseminated the diseases to the human through their contaminated dairy products and meat.
