Cryptosporidium infection in bovine calves: prevalence and potential risk factors in northwest Ethiopia

Abstract

Abstract Objective Cryptosporidium is an enteric protozoan organism that causes gastrointestinal disorders in different animals, mainly in calves. The parasite has also a zoonotic importance of children and immunocompromised patients. However, data are limited to northwest Ethiopia. Therefore, we conducted a cross-sectional survey from October 2014 to April 2015 to estimate the prevalence of Cryptosporidium infection and to identify potential risk factors in bovine calves in northwest Ethiopia. Results Out of the 360 examined calves, Cryptosporidium oocysts were recorded in 67 (18.6%) calves. Risk factors such as age, hygiene, faecal consistency, feed source, water source and contact with other domestic animals were significantly (P 0.05) were not recorded between Cryptosporidium infection and gender, body condition score, breed and study sites. Using multivariable analysis, age, feed source, water source, hygiene and close contact with other domestic animals were recognized as potential risk factors for the occurrence of Cryptosporidium infection. This study clearly figures out that Cryptosporidium infection is prevalent in the study area. Therefore, further studies, extension services and community education are recommended to adopt an integrated control approaches.
