| Sumario: | Increasing number of human cases of abdominal angiostrongyliasis has been diagnosed in the south of Brazil. The main definitive host of Angiostrongylus costaricensis in Central America is the cotton rat (Sigmodon hispidus) that does not occur in South America, except in the north of Colombia, Peru and Venezuela. Rodents were captured in the endemic area in Rio Grande do Sul (RS) and definitive hosts were identified for the first time in Brazil: Oryzomys nigripes and Oryzomys ratticeps. O. nigripes is a small wild rodent and it appears to be the main definitive host of A. costaricensis in the highlands of RS, Brazil's southermost State. |
