Prevalência de anticorpos anti-Babesia equi em eqüinos no Planalto Catarinense

Abstract

Para avaliar a prevalência de anticorpos anti- Babesia equi, através da técnica de imunofluorescência indireta (IFI), foram examinados 397 amostras de soro. As amostras de sangue, para obtenção dos soros, foram coletadas de eqüinos de diferentes idades, raças, sexos, nascidos e criados no Planalto Catarinense, dos municípios de Lages, São Joaquim, Bom Jardim da Serra, Campos Novos, Anita Garibaldi, Curitibanos e Correia Pinto. Os resultados obtidos indicaram a existência de 50,38% de animais sorologicamente reativos para B. equi, na diluição de 1:40. Entre os municípios, os percentuais de animais soropositivos variaram de 18,51% a 64,70%.

Factors associated to Theileria equi in equids of two microregions from Rio de Janeiro, Brazil

“…The lack of association with gender is consistent with other studies (SHKAP et al, 1998;SOUZA et al, 2000;BOTTEON et al, 2002;KOUAM et al, 2010). However, a weak association (p < 0.047, OR = 1.498) was reported by Moretti et al (2010) that found a higher prevalence of anti-T. equi antibodies in females compared to males.…”

“…The seroprevalence above 75% seen in animals aged six to 12 months indicate that there exists enzootic stability for T. equi in the microregions studied (MAHONEY; ROSS, 1972). The lack of association between age and seropositivity for T. equi is consistent with some reports in the literature (SHKAP et al, 1998;SOUZA et al, 2000;BOTTEON et al, 2002;MORETTI et al, 2010). However, other studies found inconsistent results (RIBEIRO et al, 1999;RÜEGG et al, 2007;KOUAM et al, 2010).…”

“…Other studies reported a prevalence of T. equi infection similar to that found in the present study (BALDANI et al, 2004;XUAN et al, 2001;HEIM et al, 2007). However, the prevalence of T. equi infection reported in southern Brazil is lower than that reported in present study (CUNHA et al, 1996;SOUZA et al, 2000;NIZOLI et al, 2008;GOLYNSKI et al, 2008). This difference may be due to climate influence in the biological cycle of R.…”

Seroprevalence rates of antibodies against Theileria equi in team roping horses from central-western region of Paraná

“…The lack of association with gender is consistent with other studies (SHKAP et al, 1998;SOUZA et al, 2000;BOTTEON et al, 2002;KOUAM et al, 2010). Considering age, seropositivity was found in 82 animals with 1-5 years; 122 5<10; and 38 ≥10 years.…”

Prevalence of equine Piroplasmosis and its association with tick infestation in the State of São Paulo, Brazil

“…(B.) microplus is the only tick found parasitizing horses, especially in southern Brazil (SOUZA et al, 2000). Rhipicephalus.…”
