Abstract

Objective: To study nematode parasites morphology of Hystrix javanica (H. javanica), both through the feces and internal organs.

Methods: Feces were observed by direct smear method, internal organs were observed after dissecting the host. Specimens for light microscopy examination were fixed with 70% warm alcohol, cleared and mounted in lactophenol for wet mounting. Specimens for SEM examination were postfixed in cacodylate buffer and glutaraldehyde, dehydrated through a graded series of alcohol and freeze dried. The specimens were attached to stubs with double cello-tape, coated with gold and observed with a JSM5310 LV electron microscope. Figures were made with the aid of a drawing tube attached to Olympus compound microscope, other figures were photographs of scanning electron microscope images. Measurements were given in micrometers as the mean followed by the range in parentheses, unless otherwise stated.

Results: The nematode species found in the intestine of H. javanica are Gireterakis girardi and a new species, Trihuris landak. The new species differs with previously reported species from Hystrix because of having stylet and short cervical alae. The pattern of bacillary band is closed to Trichuris trichiurus, the species that infect human, but differs because the surface of its vulva is not covered with densely spine.

Conclusions: The species of nematodes found on H. javanica were Gireterakis girardi and a new species Trichuris landak n.sp. Those two species are newly recorded in Indonesia.

Keywords: Gireterakis girardi; Hystrix; Indonesia; Java; Javan porcupine; Trichuris landak n. sp..
