Abstract

The current study aimed to detect the prevalence, economic losses and molecular characterization of C. bovis in slaughtered cattle from El-Menofia Province Egypt, through phase starting from January 2022 to December 2022. A total of 9488 slaughtered cattle carcasses (7638 male and 1850 female) were inspected. The findings showed that 0.98% of slaughtered cattle had C. bovis. Females were more susceptible than males to infection at 3.2% and 0.44%, respectively. The predilection sites were heart, masseter muscle with a prevalence of 0.67%, 0.31%, respectively. The entire carcass was condemned in one case with heavy infection with prevelance 0.01%. The presence of C. bovis was associated with the age of the inspected carcass. The increased prevalence was observed in female cattle older than 5 years. The prevalence was highest in summer and spring at 1.1 % followed by autumn at 0.95% and winter at 0.74%. Concerning the molecular charachterization of C. bovis the resulting sequences were blasted on the BLAST site (Basic Local Alignment Search Tool). The amplified DNA was yielded the expected band size. The sequence of C. bovis in this study was highly identical with other sequences of C. bovis which was deposited in gene bank. The phylogenetic tree revealed that the current study was founded C. bovis in the same genetic clade with the gene bank sequences of C. bovis. It is concluded from the current study that C. bovis. is a common zoonotic disease between man and animals, so the latent danger increase due to wrong disposal of infected animal bio-waste in addition to unefficient methods of slaughtering and how to deal with this infected organs. Cysticercosis caused significant economic losses, with an estimated total annual loss of 102200 Egyptian Pounds due to the condemnation of organs in this study.
