Infective larvae of the rat lungworm Angiostrongylus cantonensis, the causative agent of parasitic meningoencephalitis in man, have been found in about 4% of the stomach contents of freshwater prawns examined in Tahiti. This is believed to constitute the main source of the local human infection. These crustaceans and "taioro," a food consisting of grated coconut and prawn juice, are commonly eaten raw by Tahitians and some local Europeans. Infected mollusks have also been found on vegetation commonly eaten raw, and may constitute an occasional source of human infection. Laboratory-raised rats have been experimentally infected with A. cantonensis by applying infective larvae on the abraded skin. No infection occurred when the larvae were placed on the intact skin. In addition to land mollusks, the freshwater snail (Fossaria ollula) was also found to be a suitable intermediate host for A. cantonensis.

Eosinophilic Meningoencephalitis

The rodent lungworm A. cantonensis has been found in Hawaii in association with cases of eosinophilic meningoencephalitis. Since the clinical and laboratory findings in Hawaii are similar to those reported in man in Tahiti, and since the parasite is very common among rodents and various intermediate and carrier hosts in that area, it is believed that it is also responsible for the disease in Tahiti.

Abstract The semi-slug, Parmarion martensi, is an intermediate host of the zoonotic nematode, Angiostrongylus cantonensis, the aetiological agent of neuroangiostrongyliasis or rat lungworm disease in humans. Rearing methods were developed for P. martensi to facilitate studies on nematode transmission and control. Parmarion martensi exhibited high survivorship when reared on a diet of dog food and fresh fruits and vegetables in temperature-controlled cabinets at 21.4°C, 98% relative humidity and 12:12 L:D cycle. Rearing containers were lined with moist paper towels for substrate and plastic pots were provided for hiding/resting and egg-laying. Under these conditions, time to first reproduction was 165.3 ± 12.3 days, fecundity was approximately 34.5 ± 7.8 eggs per adult, and hatch rate was 52.7 ± 3.2%. Survivorship post egg hatch was 86.2 ± 2.9% at 30 days (neonates had a mortality rate of about 14%) and 99% thereafter for up to a year. The demographics of laboratory-reared and wild-caught P. martensi were similar except for the weight of reproductive adults, which was significantly higher in laboratory-reared adults (4.0 ± 0.2 g) than in field-collected adults (1.5 ± 0.1 g).
