2022	Serological Investigation of Different Abortive Pathogens in One Humped Camels, Iraq	International Congress on Applied Sciences
Abortion in domestic animals is a specific source of decline economy in the field of agriculture. The current study is determine the prevalence of important abortive infectious diseases including brucellosis, chlamydiosis, neosporosis, toxoplasmosis, Middle East Respiratory Syndrome (MERS) and Peste des petits ruminants (PPR) in camels using enzyme-linked immunosorbent assay (ELISA). Overall, 184 adult female one-humped camels (Camelus dromedaries) of ≥ 6 years age old were selected from different areas in Wasit province /Iraq (March 2021 to January 2022). Sera obtained from collected blood were examined using specific indirect ELISA kits. Based on OD values of positive camels, infections were classified as weak, moderate and severe. The data were analyzed by GraphPad Prism with Chi-square (x2), t-test, and one- with two-way ANOVA. Totally, 46.74% of camels were showed seropositivity to at least one pathogen. Brucellosis revealed significant seroprevalence (25.54%) in comparison to PPR (15.76%), MERS (12.5%), toxoplasmosis (9.78%), chlamydiosis (5.98%) and neosporosis (3.26%). Findings of mixed infections were significantly seen in camels with brucellosis and PPR (15.48%). Concerning ODs, weak infection was significantly increased in neosporosis (83.33%) and MERS (78.26%). In addition, significant higher ODs values were detected in brucellosis (0.4470.018), toxoplasmosis (0.4080.024) and chlamydiosis (0.3980.03). In conclusion, this study is unique as it is the first Iraqi study investigates successfully the prevalence of neosporosis and PPR in camels. However, further quantitative and qualitative studies are required to detect the impact of all targeted diseases and other abortive pathogen on reproductive status of camels through isolation or using molecular assays.
