Prevalence and Risk Factors of Bovine Hydatidosis in North Kordofan state Sudan

Abstract

An abattoir survey was conducted on 244 cattle slaughtered at Elobied abattoir in North Kordofan state, Sudan, during the period which extended from March to May 2011. The objective was to estimate the prevalence of hydatid cysts in cattle and to investigate risk factors associated with the disease. Routine meat inspection procedure was employed to detect the presence of hydatid cyst in visceral organs (liver, lung, heart and peritoneum). Selected cattle originated from three States: Darfur, Kordofan and White Nile States. The overall prevalence was 2.5% . The prevalence of hydatid cysts infection according to age of cattle was 4.4% in animals more than 5 years and 1.2% in animals less or equal to 5 years. The distribution of the hydatid cysts according to the area (states) of cattle was 3.4% in Darfur, 1.3% in Kordofan and 0.0% in The White Nile. As for body condition the prevalence was 2.5% in good body condition and 0.0% in poor body condition. Regarding distribution by sex, the prevalence of hydatid cysts was 3.0% in male and 1.2% in female. Also, prevalence of hydatidosis in presence of dogs was 2.8% and 1.4% in the absence of dogs. The prevalence of hydatidosis in breed of animals was 8.3% in fuga, 2.5% in Baggara and 0.0% in Kenana. Also, prevalence of hydatidosis when carcasses not disposed was 2.9% and 0.0% when carcasses disposed. Univariate analysis by using the Chi-square for each following risk factors was : breed (P-value = 0.278), age of animal (p-value = 0.120), origin of animals (P-value = 0.449), body condition (p-value = 0.573), sex (p-value = o.405), presence of dogs (p-value = 0.523) and disposal of carcasses (p-value = 0.294) . The risk factors like age, breed and disposal of carcasses were found significantly associated with hydatidosis ( p-value ≤ 0.30). Using multivariate to determine the association between hydatidosis and significant risk factors, only age was found significantly associated with hydatidosis (P-value = 0.036).
