Host/vector of these species

Changing epidemiology of Angiostrongyliasis cantonensis in Okinawa prefecture, Japan View info about Adobe Acrobat PDF format
Okinawa Prefecture experienced an outbreak of angiostrongyliasis in January of2000 (I). The origin ofthe infection's outbreak could not be identified. We examined the past records of Angiostrongylus eantonensis (Ae) infection outbreaks and investigated the current distribution of Ae's intermediate and paratenic hosts with infective third-stage larvae in Okinawa. In order to find the infective larvae of Ae in the giant African snail, Achatina fulica, the pallial organ (lung) of the snail was compressed between two glass plates and examined under a microscope (2) (Figs. lA, IB). In other host animals, the whole body was digested in artificial gastric juice (l% pepsin/l% Hel), and the digested material was allowed to sediment; the sediment thus formed was then examined microscopically. In particular, albino rats were given larvae from Platydemus manokwari and Parmarion martensi orally with the specimen, and identification was made based on the morphology of the adult Ae recovered at 59 days post-inoculation.
