| angiostrongylus costaricensis: first record of its occurrence in the state of espirito santo, brazil, and a review of its geographic distribution. | abdominal angiostrongyliasis is a parasitic disease caused by angiostrongylus costaricensis, a metastrongylid nematode with wide geographic distribution, occurring from the united states to argentina. in brazil, the disease has been reported from the states of rio grande do sul, santa catarina, paraná, são paulo, federal district of brasília and minas gerais. we report here a case of abdominal angiostrongyliasis in a 9-year-old girl, from itatiba, state of espirito santo, brazil, submitted to ex ... | 1995 | 8599070 |
| abdominal angiostrongylosis in southern brazil--prevalence and parasitic burden in mollusc intermediate hosts from eighteen endemic foci. | angiostrongylus costaricensis is a parasitic nematode of rodents and molluscs are the intermediate hosts. nocturnal collection of molluscs and search for infective third stage larvae of a. costaricensis was carried out in 18 endemic foci identified by the notification of a confirmed diagnosis in human biopsies or surgical specimens. molluscs were digested in acidic solution and isolation of larvae eventually present was done in a baermann funnel. larvae identified by the presence of a delicate g ... | 1997 | 9302406 |
| [identification of wild rodents as hosts of angiostrongylus costaricencis in southern brazil]. | 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. nigrip ... | 1990 | 2135366 |
| phyllocaulis variegatus--an intermediate host of angiostrongylus costaricensis in south brazil. | molluscs collected in five localities in the state of rio grande do sul (brazil) were digested and examined. the infected slugs were identified as phyllocaulis variegatus and the larvae found were inoculated per os into mice. after 50 days, worms with the caracteristics of angiostrongylus costaricensis were recovered from the mesenteric arterial system. the results establish the role of p. variegatus as intermediate host of a. costaricensis in south brazil, where many cases of abdominal angiostr ... | 1989 | 2319952 |
