EPIDEMIOLOGICAL AND CLINICAL MANIFESTATIONS OF BLOOD PARASITIC INFECTIONS IN CATTLE IN ASSIUT GOVERNORATE EGYPT

Abstract

This research paper presents the epidemiological data and clinical manifestations of blood parasitic infections in cattle. A total of 130 blood samples were collected from animals exhibiting clinical signs suggestive of blood parasitic infection. Microscopic examination of blood smears revealed an overall infection rate of 46.2% among the examined cattle. Theileria sp. infections were found to be the most prevalent, with an overall prevalence of 40%. Babesia sp. infections had a lower overall prevalence of 6.2%, Microscopic examination also highlighted the intracellular localization of Theileria and Babesia parasites within red blood cells. The infected red blood cells exhibited morphological changes, appearing enlarged and distorted compared to unaffected cells. The study analyzed the risk factors for Theileria sp. and Babesia sp. infections in cattle, specifically focusing on age and gender. The prevalence of Theileria sp. infection was highest in cattle less than one year, with no significant difference observed among different age groups or genders. Similarly, there was no significant difference in Babesia sp. infection rates based on age or gender. These results provide valuable insights into the epidemiology and clinical manifestations of blood parasitic infections in cattle. The findings can contribute to the development of effective control and prevention strategies, highlighting the importance of regular surveillance and management practices in mitigating the impact of these infections on cattle health and productivity.
