Prevalence and Risk Factors of Intestinal and Tissue Coccidian Parasites among Veterinary Personnel and Abattoirs Workers in Almnagil and 24 Algorashi Localities, Gezira State, Sudan (2020-2021)

Abstract

Coccidian parasites cause a zoonotic disease in tropical and subtropical countries, Parasitic infections are still a significant health problem in developing countries. Coccidian parasites are distributed world-wide mainly in developing country as Sudan. The study aimed to determine the prevalence of coccidian parasites infections among population contact with animals in Almnagil and 24 Algrashi Localities in Gezira state, Sudan. from 120 blood and stool samples were collected randomly from study participants , Questionnaire was designed specially of this study including personal information and possible risk factors .at selected villages and 5 samples of cat feces. These samples were collected during the period between July 2020 to December 2020. The stool samples were analyzed by wet preparation, Formal- ethyl acetate Sedemintation, Znic sulfate Flotation, Sheathers saturated sugar flotation and Modified ZN stain techniques and the blood samples were centrifuged and serum obtained and examined for Toxoplasma gondii using Toxo latex test. Data were entered in Microsoft Excel and analyzed by Statistical Package for the Social Sciences (SPSS), The result revealed that the prevalence of tissue parasite was 47 (39.2%) by detection of antibody in serum, and the prevalence of Cryptosporidium was 72.5% and 31.7% by Sedimentation and Flotation techniques respectively. Other participant of this study with multiple infections by protozoa intestinal parasites detected were (62% ). The correlation between Concentration and Flotation technique was highly significant ( p. value 0.000). The study concluded that the prevalence of Cryptosporidium and Toxoplasma was high among population having contact with animals. also Cryptosporidium parvum was the only species of intestinal coccidian parasite that found in ZN technique from flotation, sedimentation. The cat feces samples is negative results. The study recommended that the screening of intestinal and tissue coccidian parasites should be done regularly to all population contact with animals by concentration technique and Toxo latex test as well as health education.
