Summary 1. Interspecific competition is a recognized but under‐studied mechanism by which invasive species affect native fauna. 2. We experimentally reduced populations of the introduced black rat Rattus rattus in relatively undisturbed littoral rainforest south‐eastern Australia to test its competitive impact on bush fuscipes . 3. Removal R. resulted significant and sustained increases rodent due immigration, juvenile recruitment residency females. Native juveniles were particularly...

This work includes all published records, to April 2015, of the helminths occurring in Australasian monotremes and marsupials, with due regard for synonymy an attempt include life history studies, pathological observations epidemiology. It also contains unpublished records known us referrable, by accession numbers, curated collections Australia overseas. Information is presented host family, genus, species, sub-species or chromosome race names species from which no parasites have been...

Abstract The eastern bettong Bettongia gaimardi , a potoroid marsupial, has been extinct on the Australian mainland since 1920s. Sixty adult bettongs were reintroduced from island of Tasmania to two predator-free fenced reserves Australia. We examined baseline health parameters (body weight, haematology and biochemistry, parasites infectious disease exposure) in subset 30 (13 male, 17 female) individuals at translocation again 12–24 months post-reintroduction. mean body weight increased...

We describe a case in Australia of human neural larva migrans caused by the ascarid Ophidascaris robertsi, for which Australian carpet pythons are definitive hosts. made diagnosis after live nematode was removed from brain 64-year-old woman who immunosuppressed hypereosinophilic syndrome diagnosed 12 months earlier.

Taxonomic studies of parasites can be severely compromised if the host species affects parasite morphology; an uncritical analysis might recognize multiple taxa simply because phenotypically plastic responses morphology to physiology. Pentastomids genus Raillietiella are endoparasitic crustaceans primarily infecting respiratory system carnivorous reptiles, but also recorded from bufonid anurans. The delineation pentastomids at generic level is clear, taxonomic status many not. We collected...

An 11-month-old boy developed flaccid quadriparesis after two months in Fiji, and was transferred to Australia, where a diagnosis of postinfectious myelitis made. Despite peripheral blood eosinophilia, eosinophils were not detected the cerebrospinal fluid, an infective aetiology identified. The patient died progressive bulbar dysfunction. At autopsy, numerous nematodes, identified as Angiostrongylus cantonensis, seen vessels lungs, brain spinal cord, associated with pulmonary abscesses...

Pentastomids are endoparasites of the respiratory system vertebrates, maturing primarily in carnivorous reptiles. Adult and larval pentastomids can cause severe pathology resulting death their intermediate definitive hosts. The study is a neglected field, impaired by risk zoonoses, difficulties species identification, life cycle complexities. We surveyed wild snakes tropics Australia to clarify which host possess these parasites, then sought identify using combination morphological molecular...

Sixty (19 male, 41 female) free-ranging adult eastern bettongs (Bettongia gaimardi) were captured in Tasmania and translocated to the Australian Capital Territory between July 2011 September 2012 for reintroduction into fenced, predator-proof reserves. The anesthetized physical examination screened selected diseases during translocation. Reference ranges hematologic biochemical parameters determined. Two had detectable antibodies alphaherpesviruses macropodid herpesvirus 1 2 by serum...

Abstract The native rat lungworm ( Angiostrongylus mackerrasae ) and the invasive cantonensis occur in eastern Australia. species identity of A. remained unquestioned until relatively recently, when compilation mtDNA data indicated that sensu Aghazadeh et al . (2015 b clusters within based on their mitochondrial genomes (mtDNA). To re-evaluate , we sought material would be morphologically conspecific with We combined morphological molecular approaches to confirm or refute specific status...

The occurrence of gastrointestinal helminth parasites in 40 Macropus agilis, 12 M. antilopinus, 39 dorsalis, 28 giganteus, 29 parryi, 30 robustus and 26 Wallabia bicolor from north central Queensland was examined. A total 124 morphologically defined species encountered, comprising 103 strongyloid nematodes, 6 trichostrongyloid 2 spiruroid 4 oxyuroid 7 anoplocephalid cestodes digenetic trematodes. Helminth communities each macropodid host exhibited a high level diversity, were dominated...

A captive yellow-tailed black cockatoo (Calyptorhynchus funereus) and 2 free-living tawny frogmouths (Podargus strigoides), both native Australian species, were presented with neurologic signs including depression pelvic limb paresis paralysis. Despite supportive treatment, all 3 birds died or euthanatized. On histologic examination, sections of metastrongyloid nematode larvae found in the central nervous system birds, whereas intact larvae, identified as Angiostrongylus cantonensis,...

Summary Fasciola hepatica infection was found in 5 of 12 marsupial and 1 3 eutherian species examined southeastern Australia. Prevalence ot native mammals as follows; Macropus gigantcus , 59%; M. rufogriseus banksianus 15%; Wallabia bicolor 5%; Vombatus ursinus 30%; Trichosurus vulpecula Rattus fuscipes 4%. Collection sites were assigned to one two categories. higher macropodids collected on agricultural pastures grazed by sheep cattle (category A) than forested areas variably livestock B)....

Capillariid nematodes (Trichinelloidea: Capillariidae) parasitic in Australian dasyurid, peramelid and potoroid marsupials murid rodents are described. Diagnosis of the genus Eucoleus a key to species given. Two redescribed: E. gastricus (Baylis) rickardi (Beveridge Barker), comb. nov. Nine described as new: breviductus sp. nov., buckenbourensis fluvidus longiductus parvulus perplexus plumosus posterus pseudoplumosus Three additional recognized but not named.
