Physiological and epidemiological study of some parasitic and viral enteric infections in dromedary camels in Al-Muthanna province.

ABSTRACT

Understanding the normal physiology of the body is the key to study the changes that occur due to any infection. It is known that enteric infections play a considerable role in affecting normal body status. Thus, this study was designed for investigating the enteric infections in Arabian camels in Al-Muthanna Province. In this investigation, 588 fecal and blood serum samples (for diarrheic camels only) were collected from the camels in different areas of Al-Muthanna Province, Iraq from both sexes of different ages during the period from October 2020 up to the end of August 2021. The samples were examined using routine microscopic examination techniques, hematological techniques, and ELISA for parasitic and viral identification. Eimeria rajasthani, Isospora orlovi were recorded for the first time in Iraqi camels with clinical signs of diarrhea, dehydration, and emaciation. The study recorded four types of protozoa Eimeria spp., Isospora, Cryptosporidium and Balantidium coli. The recorded types of Eimeria were E. dromedarii, E. cameli, and E. rajasthani. There was a significant effect of age on infection rates with Eimeria spp. as the highest Eimeria ratio was in ages of less than two years animals. The infection rates were also affected with months which reached the highest ratios of Eimeria in October while the lowest ratio of Eimeria was recorded in July. BVDV infection rate was found in camels that suffered from diarrhea. There is no significant effect of sex on the onset of the viral disease in camels. For hematological parameters, there were significant differences in RBCs, WBCs, Hb, and PCV values in protozoal and BVDV infections. In conclusion, different kinds of protozoal and viral infections were recorded. Some of the recorded infections were associated with acute clinical signs and have zoonotic importance.
