Prevalence and Risk Factors of Cysticercusbovis in Dillig

Abstract

A cross-sectional study was conducted on 300 cattle slaughtered at Dillingslaughterhousein South Kordofan state, Sudan, during the period extended from November 2014 to January 2015 to estimate the prevalence of Cysticercusbovis infection in slaughtered cattle and to investigate potential risk factors associated with the disease. Routine meat inspection procedure was employed to detect the presence of Cysticercusboviscysts in predilection sites, which were shoulder muscle, heart, masseter(cheek) muscle, lung, tongue and liver.The study showed that the overall prevalence was 9%. A univariate analysis was performed using the chi-square as a test of significance for the association between the infection and the investigated potential risk factors. a significant association was detected between cysticercusbovis infection and each of sex (p-value = 0.102), age (p-value = 0.08), body condition (p-value = 0.025) and grazing type(p=0.00) but there is no significant association between the breed (p-value = 0.861)and animal source (p-value = 0.861) . Multivariate analysis was performed using logistic regression to the significant risk factor. A significant association was detected between, age (p-value .049), type of grazing (p-value = .002) and infection, while no association between, sex (p-value =.366), (p-value = .122) and infection. Ourstudy showed that the liver and lung wasthe infected organs, while no infection was found in the rest of the organs. Macroscopic examination of the 597 cysts (found in 27 affected animals) revealed that 332 cysts (56.11%) were viable, while 262 cysts (43.86%) were calcified.
