“…With regard to age, Pinheiro et al (2009) andClementino et al (2007) found results similar to those of this study. We found that seroprevalence increases with age, suggesting that most animals acquire post-natal infection and according to Dubey and Kirkbride (1989) animals over three years of age have longer exposure to sporulated oocysts and increased risk of infection.…”

“…However, some studies have reported that dogs can mechanically transmit oocysts through the feces to men (Frenkel & Parker 1996, Lindsay et al 1997, Clementino et al 2007). On the other hand, dogs epidemiologically act as perfect sentinels of T. gondii infection to men, allowing the evaluation of the rate of environmental contamination with oocysts in both urban and rural areas, as well by ingestion of raw or undercooked meat with tissue cysts (Souza et al 2003, Azevedo et al 2005, Langoni et al 2006, Santos et al 2009).…”

“…The infection prevalence varies with the different species depending on occurrence area, socio-cultural habits, besides weather and geographic factors. Man and animals become infected by ingesting raw or poorly cooked meat containing tissue cysts (Dubey & Beattie 1988) and by ingesting oocysts present in contaminated feces of cats (definitive hosts) (Frenkel & Parker 1996, Lindsay et al 1997, Clementino et al 2007). Thus, dogs are epidemiologically important since they act as sentinels of the infection to men, mainly errant animals or those with free access to other uncontrolled places preying on birds and rodents (Kawasoe 2000, Brito et al 2002, Azevedo et al 2005, Sedlak & Bartova 2006.…”

“…Resultados semelhantes à presente pesquisa em ovinos foram detectados em outras regiões do Brasil, como no Distrito Federal, onde foram encontrados 38,2% de soropositividade para anticorpos contra T. gondii; 34,7% no estado de São Paulo; 29,41% em Lajes, Rio Grande do Norte, e 28,2% no estado de Sergipe (Figliuolo et al, 2004;Clementino et al, 2007;Ueno et al, 2009;Mendonça et al, 2013).…”

“…Outros estudos também evidenciaram uma maior quantidade de sororeagentes nos ovinos mais velhos (Figliuolo et al, 2004;Clementino et al, 2007;Pinheiro et al, 2009). Tal fato pode ocorrer já que, à medida que os animais adquirem mais idade, há um aumento da exposição ao protozoário.…”
