“…Previous studies of infected eastern grey kangaroos failed to demonstrate living or degenerating microfilariae within the spleen, however a granulomatous splenitis has been reported in swamp wallabies and mountain brushtail possums (Trichosurus caninus) in response to the presence of Breinlia spp. 1,2 The eosinophilic infiltration observed in this animal has been described previously in eastern grey kangaroos. 6 In wallaroos, the natural host of P roemeri, microfilariae were frequently seen in the blood vessels of the spleen but degenerating microfilarae were not evident in any tissues.…”

“…Simpson's Index (Table I) was higher than that reported from some studies of nematodes of other mammals (Beveridge et al, 1985(Beveridge et al, , 1989Pence & Meinzer, 1979) and similar to others (Holmes & Podesta, 1968). No one species or group of species was found to be dominant.…”

The digestive systems of 86 canefield rats from Ingham, Queensland were examined for parasites. One species of cestode and seven species of nematode were found, all but one being new host records. The helminth community was characterised in terms of core, secondary and satellite species. No core species were identified, but Nippostrongylus typicus and Odilia emanuelae were identified as secondary species. All other species were identified as satellite species. The strongyloid nematode Ancistronema coronatum n. g., n. sp. is described. Ancistronema differs from other genera in the Chabertiidae in having a short buccal capsule and in the number and shape of the elements of the internal and external leaf crowns. This is the first record of a strongyle from Australian rodents. It is postulated that it came into Australia with ancestral Rattus sp. hosts which colonised Australia from Indonesia less than a million years ago.

“…Although several different morphotypes were seen, identification to genus level was not possible. The characteristic egg of Globocephalolides trifidospicularis (Beveridge et al, 1985) was not identified in any sample. Fecal egg counts were highly variable (range: 0-2,362 epg, mean6S.D.…”

The brush-tailed rock-wallaby (Petrogale penicillata) is listed as vulnerable on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. Parasitic diseases have been proposed as possible contributing factors to the decline of the species, but very little is known about the effects of parasites on this host. This study determined the antibody prevalence of the protist Toxoplasma gondii in a wild brush-tailed rock-wallaby population from three neighboring colonies in southeast Queensland, Australia. Fecal egg and oocyst count, tick count, severity of skin rash, and presence of lice and microfilariae were also monitored during four or five trapping periods over 1 yr. Antibodies against T. gondii were detected in 5% of animals (3/64). Fecal egg and oocyst counts were highly variable, but fecal egg counts were lower in subadult animals relative to adults. Neither fecal egg count nor oocyst count was associated with variation in blood variables or condition index, but a negative association between fecal egg count and oocyst count was observed. Microfilariae (Breinlia spelaea), lice (Heterodoxus octoseriatus), and skin lesions were seen more frequently during the November trapping period. A mite, Thadeua sp., was more likely to be detected in these skin lesions than in skin of unaffected wallabies. Tick (Ixodes holocyclus and Haemaphysalis bancrofti) counts also varied between trapping periods and were lowest in the April/May trapping period. This study provides the most detailed account to date of parasite burdens in a vulnerable macropodid, but no clear evidence emerged linking parasites to adverse impact on the host.
