| Popis: | We had the opportunity to examine the carcass of a female thicktailed bush baby (Galago crassicaudatus) bred in Tama-Zoo, Tokyo. This carcass was one young galago of 4 head (2 males and 2 females) which were caught at the east part of Africa and died at one month after the importation to Japan at November 1987.As the results of necropsy, 25 encapsulated nymphs of pentastomes were found in or on the parenchyma of the abdominal-wall, diaphragm, mesenteries, liver, lung and spleen, recognized as conspicuous annular worms and coiled within a transparent thin-walled cyst. These measured 4-6 mm in diameter. No other gross lesions were found. The cause of the Galago' s general illness was not ascertained, nor was the source of the pentastomes.The cylindrical nymphs were identified as Armillifer armillatus based on the characteristic pronounced annulations of the integument and by the number of these annulations (16 to 20).At microscopical examination of sections of encysted nymphs in liver and diaphragm, the nymph was enclosed in a fibrous cyst wall and there were a encysted nymph showing prominent acidophilic glands and intestinal tract; the chitinous cuticle was smooth without spins, 6.4 μm thick; subcuticlar glands and muscle fibres were apparent beneath the cuticle. Neither degenerative nor granulomatous inflammatory reactions noted in the adjacent tissue.Nymphal pentastomes are capable of developing in a wide of intermediate hosts.Armillifer armillatus nymphs have been reported from various terrestrial animals, including insectivora, carnivora (lion, dog, leopard, mongoose), rodentia (rat, squirrel), ungulata (antelope), primates (monkey, macaques, galagos, guenons, mangabey, baboons, chimpanzee, man) (Sambon, 1922; Flynn, 1973). Although this parasite occurs naturally only in tropical Africa, when these worms were imported to Japan with these animals, this parasite will be possible to occures the problem as a zoonotic parasites. |
