Description of the male Pterygodermatites nycticebi (Mönnig, 1920) unknown until the present study, and a study of the cephalic and cuticular structures of the female. This rictularid has a morphological evolution comparable to that of other males of the Rictulariidae parasitic in viverrid carnivores and in primates.
A case of double infection with Brugia pahangi and Dirofilaria immitis in a clouded leopard, Neofelis nebulosa, is presented. A brief review of filarial infections in both man and wild animals, and their medical importance is discussed.
Examination of naturally infected felids and viverrids in Malaysia confirmed previously published records which indicated that P. westermani occurred only in felid cats. Felis planiceps and F. temnickli were reported as new host records. Analysis of stomach contents revealed no crab remains in either family of cats, but confirmed that felids were strictly carnivorous while viverrids were often omnivorous. In feeding experiments, only viverrids ate the host crabs Potomiscus johorensis and Parathelphusa maculata. The probable transmission of P. westermani to felids via paratenic hosts was discussed.
The recovery of six adult Gnathostoma spinigerum Owen, 1936 from a civet cat, Prionodon linsang Hardwick, constitutes the second reported record of this parasite and the first authenticated case of adult worms found in a wild animal from Malaysia. The food habits of the infected P. linsang as an important link in the transmission of G. spinigerum in the intermediate and definitive hosts together with the probable distribution of this parasite are discussed.
