Abstract: Neospora caninum and Toxoplasma gondii are coccidian parasites (protozoa: Apicomplexa) that cause reproductive losses in ruminants. Although, in sheep, abortion is generally related to T. gondii, potential damage caused by N. caninum must be considered. The aims of this study were to evaluate the frequencies of antibodies against Neospora spp. and T. gondii, and to identify the risk factors related to neosporosis and toxoplasmosis in sheep from ten flocks located in Central-Western, Northwestern, Southwestern,… Show more

“…Although neosporosis is a major cause of abortion in cattle worldwide (Dubey et al, 2007) abortion and neonatal mortality associated with N. caninum were reported in sheep and goats (Dubey, 2003;Dubey and Schares, 2011;Porto et al, 2016). The presence of canids and felids together with small ruminants in the pastures, pens, and barns act as potential epidemiological factors for these protozoa infections (Mainar et al, 1996;Ferreira et al, 2016;Udonsom et al, 2020).…”

“…Dünyada koyunlarda hem T.gondii hem de N. caninum'un seroprevalansının birlikte araştırıldığı çalışmalarda miks enfeksiyon oranları %2.75-9.03 olarak tespit edilmiştir [12,19,21,22]. Bu çalışmada ise miks enfeksiyon oranı %11.53 olarak belirlenmiştir.…”

“…The minimum sample size required for this study was calculated using EpiInfo 7.1.5 (Centers for Disease Control and Prevention [CDC], 2002), using 16.3% (Ferreira et al, 2016) as the expected prevalence, with a margin of error of 5%, and a confidence interval of 95%. Given an estimated total population of 327.828 sheep in the region studied according to data from the Instituto Brasileiro de Geografia e Estatística [IBGE] (2014), a minimum sample size of 224 was required.…”

“…Over the span of a decade, researchers found a prevalence of 3.2% (2/62) in sheep sampled from Rio Grande do Sul state (Vogel, Arenhart, & Bauermann, 2006) and a recent study reported a seroprevalence of 16.3% (49/300) in ovine (Ferreira et al, 2016). However, a study by Ferreira et al (2016) included only one city, Bossoroca, where only 30 sheep samples were collected from this region. Vogel et al (2006), collected only 22 sheep samples from the city of Jóia, also in the northwest of the state.…”
