Two adult rock partridges raised in a city zoo were examined parasitologically and pathologically. Two distinctive eggs resembling those of Capillaria and Heterakis were detected in the feces. At necropsy, a markedly-dilated duodenum with severe catarrhal exudates, containing adult worms of Capillaria sp. and Heterakis sp. in the cecum, was observed. Male Capillaria had the cloacal aperture extended almost terminally with a small bursal lobe and an unsheathed spicule with transverse folds without spines. Female Capillaria had a vulva that was slightly prominent and slightly posterior to the union of the esophagus and intestine. The esophagus of the adult Capillaria was more than a half as long as the body in the male, but was much shorter in the female. Based on these morphological features, the capillarid nematode was identified as Capillaria obsignata. The male adult worms of Heterakis was identifiable by 2 dissimilar spicules, a unique morphological feature where the right spicule was considerably longer than the left, which is also a characteristic feature of Heterakis gallinarum. This is the first report of concurrent infections with C. obsignata and H. gallinarium in rock partridges.

A weanling Thoroughbred foal was admitted to Equine Hospital, Korea Racing Association with signs of colic. On admission the foal was sweating profusely, appeared anxious and exhibiting signs suggestive of abdominal pain. Clinical examination revealed: tachycardia (90 beats/min), tachypnea (50 breaths/min) and congested and slightly cyanotic mucous membranes. No intestinal sounds were auscultated in all 4 abdominal quadrants. Rectal palpation identified concurrent cecum and large colon impactions. Treatment consisted of intravenous administration of a balanced electrolyte solution, nasogastric siphonage and administration of analgesics. Nasogastric reflux contained ascarids. This treatment failed to alleviate the signs of colic. The foal died 3 hours later following discharge because the owner didn't want laparatomy because of economic constraints. Prior to admission this foal had not received any prophylactic anthelmintic treatment. In necropsy, there were masses of ascarids accumulation in the stomach, small intestine and large intestine. The outcome of this report is to describe the first diagnosed case of gastrointestinal impaction by P. equorum in a Thoroughbred foal in South Korea and indicates the importance of regular anthelmintic treatment.

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

METHODSFeces 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.

RESULTSThe 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.

CONCLUSIONSThe 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.
