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.

New Host Records

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.

Insight Into

In R. fuscipes from seven Victorian localities: 15 nematode and five cestode species were found; Bertiella anapolytica, Capillaria gastrica and Stammerinema suffodiax represented new host-parasite records for R. fuscipes, and the latter two were new helminth records for Australia. Capillaria praeputialis, sp. nov., and Paraustrostrongylus ratti, sp. nov., are described. Insight into the feeding habits and the interrelationships of R. fuscipes with other fauna was sought from the parasite data. One cestode (Choanotaenia ratticola) and two nematode species (Dipetalonema johnstoni and Stammerinema suffodiax) also occur in marsupials. Two helminth genera (Bertiella and Paraustrostrongylus) with extensive radiations in marsupial hosts are recorded from R.fuscipes. It is proposed that these data present further evidence for the concept of secondary transfer of parasite faunas between indigenous marsupials and rodents.

<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>

Abstract The aim of this study is to determine the effectiveness of disinfectant on the viability of eggs from three nematode species (Ascaris, Trichuris, Ankylostoma). It was conducted in a microcosm from June 2018 to June 2019. The wastewater scan was sampled using 5 L sterile containers, the sample was arranged in four replicas, three tests and one control. The test samples received three disinfectants (Moringa, calcium hypochlorite and Moringa associated with calcium hypochlorite) at varying concentrations. The physical and chemical parameters were measured before and after the application of each disinfectant. The samples were then observed under an optical microscope. The viability of the eggs was determined by incubating the Petri dish samples at 30 °C for 30 days. The analyses show that some physicochemical parameters can significantly influence the efficacy of disinfectant on the eggs. The calcium hypochlorite associated with Moringa at 0.6 g/L showed greater efficacy on reducing viability and inactivation of eggs with 100% efficacy yield rates on Ankylostoma and Trichuris trichiuria and 97% on Ascaris lumbricoides eggs; this efficacy is significantly different from that observed on samples treated with Moringa and simple calcium hypochlorite. Of the three parasites tested, A. lumbricoides showed greater resistance to the disinfectant.

A new species of Mesocriconema and a unique assemblage of plant-parasitic nematodes was discovered in a heath bald atop Brushy Mountain in Great Smoky Mountains National Park. Mesocriconema ericaceum n. sp., a species with males, superficially resembles M. xenoplax. DNA barcoding with the mitochondrial COI gene provided evidence of the new species as a distinct lineage. SEM revealed significant variability in arrangement of labial submedian lobes, plates, and anterior and posterior annuli. Three other nematodes in the family Criconematidae were characterised from the heath bald. Ogma seymouri, when analysed by statistical parsimony, established connections with isolates from north-eastern Atlantic coastal and north-western Pacific coastal wet forests. Criconema loofi has a southern Gulf Coast distribution associated with boggy soils. Criconema cf. acriculum is known from northern coastal forests of California. Understanding linkages between these species and their distribution may lead to the broader development of a terrestrial soil nematode biogeography.

The desire to shore up the shortfall in protein supply, the increased awareness of the importance of cholesterol free animal protein, like guineafowl, and the need to conserve their wild genes, have necessitated studies on improved captive breeding of feral helmeted guineafowl. Hence, this study was aimed at determining the effects of ecological zones and storage systems on the guineafowl eggs. Guineafowl eggs (n=214), were collected from identified and monitored-nests within the Kainji Lake National Park (KLNP) and Old Oyo National Park (OONP). Out of 91 eggs collected from KLNP, 32 and 38 were stored at room temperature (RT-21-25°C) and refrigerator (RF-17-20°C), respectively for five days prior to incubation while 21 eggs were not stored (NS-27-29°C), and out of 123 collected from OONP, 70 and 19 were stored for five days prior to incubation at (RT-21-25°C) and (RF-17-20°C), respectively while 34 eggs were (NS- 27-29°C). Prior to incubation, eggs were weighed, the height and width were measured. The process was repeated after incubation for unhatched eggs. Candling was done three days before hatching at day 29 of egg incubation. Embryo status of unhatched eggs was determined by cracking the eggs. Descriptive and inferential statistics were used to analyse the data. The NS eggs from Kainji (7.60%) and Oyo (2.01%) had the lowest percentage shrinkage in weight across the three storage systems. The order was reversed in height with RF eggs from Kainji (0.96%) and Oyo (0.46%) having lowest. The least shrinkage in width of eggs from Oyo was recorded in the RF eggs (0.00%) and in NS (0.59%) from Kainji. Eggs candling showed that presumed fertile (opaque) was highest (69.10%) in NS eggs followed by RT (45.00%). There was no significant difference (p>0.05) between the hatchability of eggs from the two parks though hatchability (7.60%) of Kainji eggs was higher than those of Oyo (7.40%). Further check on fertilization after incubation showed that RT (37.50%) eggs from Kainji were fertilized but were unable to hatch alive so also was RF eggs (21.10%). The study showed that the eggs sizes vary with ecozones while size of the eggs and storage systems affects hatchability and survival of feral helmeted guineafowl eggs in captivity.

Thelastomatidae is one of the largest families parasitizing insects, within the order Oxyurida. In this work we reported parasitism in nymphs and adults of Neocurtilla claraziana by two different thelastomatid species as a part of a field survey on agricultural pests. Nymphs and adults of this insect were isolated from grasslands of Buenos Aires State, Argentina using a tensio-active solution. The nematode species Gryllophila skrjabini Sergiev, 1923 and Cephalobellus magalhaesi Schwenk, 1926 are briefly described and measurements are given. Both nematodes are reported for the first time in Argentina with C. magalhaesi being the second isolation of this species in the world. Neocurtilla clarziana is a new host record for G. skrjabini.
