چکیده
Morphometric data on larval and adult specimens of Angiostrongy/us (Paras/rongy/us) costaricensis Morera & Céspedes, 1971 recovered trom Swiss albino mice experimentally infected is presented. Infective larvae were obtained trom parasitized veronicellid Sa/'asinu/a /JIo/'ginoto (Semper, 1885) maintained in the laboratory. This is the tirst complete morpho1l1etric study regarding speci1l1ens of a Brazilian strain of A. (P.) cos/aricellsis.

Angiostrongyliasis in the Americas
The helminth Angiostrongylus costaricensis Morera & Céspedes, 1971 is endemic to the Americas and is responsible for a pathological abdominal syndrome, caused by the presence of the adult helminth in the mesenteric arteries. This is microscopically characterized by eosinophilic infiltration, vascular abnormality and a granulomatous reaction (GraeffTeixeira et al., 1987). The disease was first r...
متن کاملThe intermediate host of Angiostrongylus costaricensis in Honduras.
Resumen: Se colectaron babosas (Veronicellidae) en el Departamento de Morazán, Honduras. La digestión con jugo gástrico artificial mostró la presencia de larvas de tercer estadio morfológicamente semejantes a Angiostrongylus costaricensis. Se les inoculó en ratas (Sigmodon hispidus) con sonda gástrica. Cincuenta días después se obtuvieron los nemátodos adultos y se confirmó el diagnóstico. A pe...
متن کاملPotentiality of Achatina fulica Bowdich, 1822 (Mollusca: Gastropoda) as intermediate host of the Angiostrongylus costaricensis Morera & Céspedes 1971.
Samples of Achatina fulica were experimentally infected with Angiostrongylus costaricensis larvae, etiological agent of abdominal angiostrongyliasis, showing that A. fulica is susceptible to the parasite. Achatina fulica may be a risk to urbanization of abdominal angiostrongyliasis presumably due to its high proliferation, continuous dispersion and remarkable adaptation in several Brazilian towns.

The attraction exerted by Biomphalaria glabrata infected with Angiostrongylus costaricensis on Schistosoma mansoni miracidia of the BH strain was tested, using a glass apparatus composed by two circular chambers connected to a channel. One mollusk or a sample of a snail conditioning water (SCW) was placed in one of the chambers, randomly selected, and the remaining of the apparatus was filled w...
متن کاملBehavior of Angiostrongylus costaricensis in planorbids.
Some terrestrial mollusks are natural hosts of Angiostrongylus costaricensis. In the laboratory, this nematode can be maintained in certain planorbids, which are aquatic mollusks and intermediate hosts of Schistosoma mansoni. Mollusks can be infected with Angiostrongylus costaricensis by ingestion of or active penetration by the first-stage larvae. In this work we assessed the ability of Biomph...
