Prevalence and risk factors for Cysticercus tenuicollis in goats and sheep in Paraíba, northeastern Brazil

Abstract: This study aimed to determine the prevalence and risk factors for C. tenuicollis among goats and sheep in slaughterhouses in Paraíba. 390 animals (195 goats and 195 sheep) in the municipalities of Patos and Esperança, Paraíba, Brazil, were inspected between February and May 2014. The prevalence of C. tenuicollis was 39% (76/195) in goats and 17.4% (34/195) in sheep. In both species, most of the cysticerci vesicles were located at the omentum and mesentery. The only risk factor found was extensive sheep farmin… Show more

“…Twenty of the 24 lambs (83.3%) presented Cysticercus tenuicollis, the larval stage of Taenia hydatigena, and one lamb presented Coenurus larvae (Taenia multiceps) in the brain. Sheep acting as an intermediate host of dog cestodes is a relatively common problem in Brazil (RISSI et al, 2008;DE LA RUE et al, 2011;MORAIS et al, 2017). Our results demonstrate that dogs are still being fed raw sheep offal after home slaughtering and/or have access to dead sheep carcasses on farms.…”

“…Lesões parasitárias constituem as principais causas de condenações de carcaças e órgãos de ovinos em matadouros. Estudos em diferentes partes do mundo demonstram que essas condenações são decorrentes, principalmente, de lesões associadas com hidatidose, cisticercose (Cysticercus ovis e C. tenuicollis) e fasciolose (Scala et al 2004, Santos et al 2010, Cardona & Carmena 2013, Khanjari et al 2015, Morais et al 2017. Aspectos semelhantes foram observados nesse estudo, no qual essas doenças também constituíram as principais causas de condenações.…”

“…Diversos estudos demonstram uma alta frequência de cisticercose por C. tenuicollis em frigoríficos de ovinos e caprinos (Soares et al 2012, Singh et al 2015, Khanjari et al 2015, Morais et al 2017. C. tenuicollis constitui o estágio larval de Taenia hydatigena, que possui como hospedeiros intermediários ovinos, caprinos, bovinos e suínos, e como hospedeiros definitivos cães e canídeos selvagens (Urquhart et al 1996, Taylor et al 2010.…”

“…After egg ingestion during grazing on pastures contaminated with faeces of infected canids, the metacestode larval stage develops in ruminant (domestic and wild) causing cysticercosis. Prevalence of cysticercosis is often very high but differs by country and host (Braae et al., 2015; Morais et al., 2017; Nguyen et al., 2016; Oryan et al., 2012; Scala et al., 2015, 2016; Singh et al., 2015; Wondimu et al., 2011).…”
