Abstract

Following the discovery of Angiostrongylus siamensis OHBAYASHI, KAMIYA et BHAIBULAYA, 1979,which is parasitic in the mesenteric artery of Rattus sabanus, the parasite was recovered from 5 rats of 278 micromammals collected from 6 localities in Thailand from July to August, 1978,and in February, 1979 : 1 to R. sabanus ; 1 to R. berdmorei ; 1 to R. rattus ; and 2 to R. surifer, thus, extending the focus of the study, which had been limited to one locality in Thailand and the host range of the parasite. The first stage larvae were fed to an experimental intermediate host, Biomphalaria glabrata, and the third stage larvae were successfully obtained on the 25th day after exposure. The third stage larvae were inoculated orally into the following laboratory animals : mice (ICR), rats (WKA), cotton rats (Sigmodon hispidus) and Mongolian gerbils (Meriones unguiculatus). Adult worms were collected from the mesenteric arteries, and partially from the aortae of the respective animals, indicating that this strain of A. siamensis had been successfully maintained in the laboratory between the snails, B. glabrata, and the small laboratory animals.
