“…In the present study, 13.74% of the animals presented antibodies anti-T. gondii, which is similar to 17.5% found in São Paulo State by Oliveira-Sequeira et al (1993) and 18.75% observed in Bahia State by Pita Gondim et al (1999) in Brazil. Similar results were also obtained worldwide with 16.2% in Noruega (Skjerve et al 1998) and 12% in Chile (Gorman et al 1999). This is the first report on serum frequency of T. gondii in sheep from the state of Tocantins.…”

“…(Leguia, 1991;Tenter, 1995). On the other hand, T. gondii-specific antibodies have also been detected in 33.5% of llamas (Dubey et al, 1992) and 16.3% of alpacas (Gorman et al, 1999). Because 1:50 IFAT titers are clearly more predominant, the use of an IFAT cutoff point of 1:50 could lead to an overestimation of the prevalence of the infection and, consequently, in such doubtful cases Western blot could be required.…”

“…A infecção por T. gondii em caprinos e ovinos encontra-se amplamente distribuída pelo mundo, apresentando soroprevalências variando entre 3,2% e 30% para caprinos (Dubey 1985, Garcia-Vasquez et al 1993, Samad et al 1993, HashemiFesharki 1996, Masala et al 2003, Sharif et al 2007, Zia-Ali et al 2007) e entre 7% e 38,5% para ovinos (Dubey 1985, Samad et al 1993, Hashemi-Fesharki 1996, Freyre et al 1997, Skjerve et al 1998, Gorman et al 1999, Masala et al 2003, Sawadogo et al 2005, Fusco et al 2007, Zia-Ali et al 2007, Sharma et al 2008. No Brasil, em diversos estados, estudos demonstram inquéritos que apresentam soroprevalências da infecção em caprinos entre 5,9% e 46,0% (Mainardi et al 2000, Figueiredo et al 2001, Silva et al 2003, Cavalcante et al 2007, Carneiro et al 2009) e em ovinos entre 7,7% e 54,6% (Garcia et al 1999, Gondim et al1999, Silva & Lagoni 2001, Ogawa et al 2003, Romanelli et al 2007, Soares et al 2009, Lopes et al 2010.…”
