The northern hairy-nosed wombat Lasiorhinus krefftii is now restricted to a single population of less than 70 individuals at Epping Forest National Park, North Queensland, Australia, and is listed as critically endangered. We examined six trapped animals for ectoparasites, and 197 faecal samples for endoparasites. All ectoparasites (the tick Ambylomma triguttatum, the flea Echidnophaga cornuta and the louse Boopia dubia) were new host records. Nematode eggs and larvae were found in every faecal sample and the number of eggs varied significantly among months sampled. Cestode proglottids were also found. There was no indication that parasites were causing disease and few species were detected. This last remaining population of L. krefftii may be relatively immunologically na�ve, and we suggest that removing them from their natural environment to other areas as part of a captive breeding program should be attempted with caution.

The bridled nailtail wallaby (Onychogalea fraenata), an endangered macropod, has been reintroduced into the wild after a captive-breeding program. As part of a management program to assess the risks to its survival O. fraenata were trapped and examined for ecto- and endoparasites. From February to September 1996, 55 wallabies from Taunton National Park, central Queensland, some trapped more than once, were visually examined for ectoparasites. The blood of 39 O. fraenata was tested for antibodies against Toxoplasma gondii and Echinococcus granulosus and a total of 82 faecal samples were examined microscopically. In addition, in a second study a complete carcase, three complete gastro-intestinal tracts, and a single stomach, obtained from various sources, including Idalia National Park, were examined for helminth parasites. The most prevalent ectoparasites were the ticksAmbylomma triguttatum and Haemaphysalis bancrofti. Other ectoparasites included four species of trombiculid mites and a louse, Heterodoxus sp. A single instance of the nippoboscid fly, Ortholfersia minuta, was found. From the serological surveys, antibodies against Toxoplasma and Echinococcus were detected in 15% and 21% respectively. No trematode or cestode eggs or protozoal cysts were found in faeces. Nematode eggs had a prevalence of 92% with a mean egg density of 500 eggs per gram. Strongyloides sp. (larvae) was the most prevalent nematode in faeces. In the postmortem study, seven nematode species (Cloacina polyxo, Hypodontus macropi, Labiostrongylus onychogale, Macropostrongyloides baylisi, Macropoxyuris sp., Rugopharynx australis and Zoniolaimus buccalis) and four cestode species (Progamotaenia bancrofti, P. zschokkei, P. abietiformis and larval E. granulosus) were found. Six of the nematode species are new host records. The presence of infection with the introduced parasites T. gondii and E. granulosus, both recognised as serious pathogens, is of management significance. Since the definitive hosts of these parasites are cats and canids respectively, control of cat, dog and dingo populations within the Park will lessen the incidence of infection with these parasites.

Abstract The aim of the study was to assess selected methods of storage and preservation of horse faecal samples on the detectability of eggs and survival rate of larvae of strongylid nematodes. Physical and chemical factors were found to have a significant effect on the egg detectability and survival of the larvae. The comparison of control and variously preserved samples revealed that each storage method affected the reliability of the results to some extent. Short-lasting, three-day freezing resulted in a decrease of detectability from 100% to 94.1%, with an equally significant decrease in the mean number of eggs per one gram of faeces, from 1,238.97 to 983.82. Extending the freezing period from 3 to 14 d had a highly significant effect on the prevalence, which was then 85.3%, while the EPG (eggs per gram) value decreased more than twice, compared to control samples, and was 503.68. Thirty-day freezing had no further effect on the parasitological indices, which did not differ significantly from those obtained after a fortnight of freezing. Storing samples in 4% formalin and 40% ethanol had a significantly more negative effect on the detectability of strongylid eggs. The prevalence in alcohol-preserved samples was 91.2% and the EPG was 247.79; the values for formalin-preserved samples were 88.2% and 153.68. The way of preserving faecal samples was also found to affect the viability of strongylid larvae.

New Host Records

The ectoparasites of northern quolls, Dasyurus hallucatus, are reported from 79 animals live-trapped at Kapalga Research Station, Kakadu National Park, during 1992–95. The ecto- and endoparasites are reported from 62 dead D. hallucatus during the same period; these were mostly road-kills collected from an 88-km section of the Arnhem Highway between Jabiru and the Northern Entry Station of Kakadu National Park. Tissues from 28 of the road-kills were examined histologically. Additionally, 214 scat samples were examined for ecto- and endoparasites. Seven species of ectoparasite, including two species of tick, a larval trombiculid mite, a louse and two (possibly three) species of flea, and 17 species of endoparasite including a trematode, a larval cestode, 13 species of nematode, a larval pentastome and a protozoan were recorded from D. hallucatus. Sarcocystis sp. was found in tissues but neither Toxoplasma gondii nor Trichinella pseudospiralis were detected in histological sections or tissue digests. Ticks, mites and nematodes were found in scats. The tick Haemaphysalis bancrofti, the flea Echidnophaga aranka and possibly E. ambulans, and the nematodes Mackerrastrongylus peramelis and Cylicospirura heydoni represent new host records for D. hallucatus. Although parasitism was common in D. hallucatus, few individuals harboured large burdens. Consequently, it appears unlikely that parasitism is a major factor contributing to the decline of northern quolls in this region.

First Time

Parasites of two high altitude ruminants Himalayan Tahr (Near Threatened) and Barking Deer (Vulnerable) were examined from the Rara National Park, located at 3000 – 4000 m altitude of Nepal, for the first time. A total of 51 faecal samples, 17 from Himalayan Tahr and 34 from Barking Deer were collected in the month of May/June 2012 and 2013. Parasites were found in all the samples of Himalayan Tahr and 33 samples (97.06%) of Barking Deer. Coccidian oocysts (Eimeria sp.), eggs of cestodes (Moniezia sp.) and gastrointestinal nematodes (Strongyloides sp., Trichuris sp., Oxyuris sp., Ascaris sp., Trichostrongylus sp. and Haemonchus sp.) and bronchopulmonary nematode larvae (Dictyocaulus sp. and Muellerius sp.) were identified by means of coprological techniques. Himalayan Tahrs were found to be highly infected with Eimeria sp. (88.24%) and Moniezia sp. (70.59%) compared to Barking Deers, Eimeria sp. (73.53%) and Moniezia sp. (47.06%). In Himalayan Tahr, prevalence of Oxyuris was found to be highest (88.24%) among various nematode parasites followed by Stongyloides sp. (64.71%), Ascaris sp. (52.94%), Trichostrongylus sp. (11.76%), Dictyocaulus sp. (11.76%), Muellerius sp. (11.76%) and Haemonchus sp. (5.88%) while in Barking Deer, 26 (76.47%) samples were found to be positive for nematode parasites. Among the nematode eggs examined, Oxyuris revealed highest prevalence (70.59%) followed by Ascaris sp. (17.65%), Trichuris sp. (8.82%), Dictyocaulus sp. (8.82%) and Haemonchus sp. (2.94%). Present findings highlight that the parasitic diseases are posing considerable threat in the conservation of wild life in Nepal.

<p>In 51 specimens of lane snapper, <em>Lutjanus synagris</em>, captured in Santiaguillo Reef, Veracruz Reef National Park System, State of Veracruz, in the Southern Gulf of Mexico, a total of 25 helminth species were recovered, as follows: 9 digeneans (8 adults, and 1 metacercaria), 7 monogeneans, 6 nematodes (4 adults, and 2 larvae), 2 cestodes (both larvae), and 1 acanthocephalan (juvenile). Out of the 25 species, 11 are new host records; 2 have prevalence &gt; 50%, and mean intensity &gt; 4.7; <em>Haliotrematoides cornigerum</em> (monogenean) had the highest prevalence, 94.11%, followed by <em>Euryhaliotrema tubocirrus </em>with prevalence of 66.67%. Richness (<em>S</em> = 25) and diversity (Shannon index <em>H’</em> = 2.13) at component community, and endoparasites infracommunity level (<em>S</em> = 6.27 ± 2.5, Brillouin index<em> H</em> = 1.07 ± 0.42), and ectoparasites infracommunity level (<em>S</em> = 3.6875 ± 1.87, Brillouin index <em>H</em> = 0.74 ± 0.4), were similar to those found in other marine fish. Results suggests that the host feeding habits determine the endoparasites composition, while the ectoparasites composition is associated to the environmental conditions.</p>
