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.
