Prevalence of Bovine Cysticercosis in Cattle Slaughtered at Gimbi Municipal Abattoir WestWollega Zone of Oromia Regional State, Western Ethiopia

摘要

Bovine cysticercosis is an infection of cattlecaused by the larval stage, Cysticercus bovis of the humanintestinal cestode, Taenia saginata . It is an infection ofpublic health significance as eating of raw or undercookedbeef results in taeniasis in human population and animportant cause of economic loss mainly due tocondemnation and downgrading of infected carcasses. Across-sectional study was conducted from November 2019to April 2020 on bovine cysticercosis in cattle slaughteredat Gimbi Municipal Abattoir with the objectives ofdetermining the prevalence of bovine cysticercosis,viability and organ distribution of the cyst. Out of 384systematically selected slaughtered male cattle a totalof 16 (4.16%) were infected with Cysticercus bovis .Among positive cases for C. bovis a total of 36 cysts werecollected in which 15 (41.66%) were viable while the rest21 (58.33%) were died cysts. The anatomical distributionof cysticerci shows highest proportion in triceps muscle12 (33.33%), masseter muscle 9 (25%), heart 7 (19.44%),liver 4 (11.11%) while the lowest in lung and kidney 2(5.55%). There was no statistical significant difference(p>0.05) in the prevalence of cysticerosis between theorigin and body condition score of the animals but therewas significant variation (p<0.05) between the age (higherprevalence in adult 2.8% than in old 1.3% age) and organdistribution of the cysts of the study animals. With respectto viable cysts, was show triceps muscle 7(46.66%),masseter muscle 4(26.66%), heart 2(13.33%), liver andkidney 1(6.66%) and none in lung 0(0%). In conclusion,the present study shows that the disease deserves specialattention to safeguard the public health and promote beefindustry in the country. Therefore, appropriate control andpreventive measures should be taken in order to reducethe disease problem on public health and economicsignificance.
