“…Spirura aurangabadensis, in turn, also had its geographic distribution expanded, since it was recorded only in India, parasitizing bats; in Malaysia, parasitizing tree shrews and primates; in Australia, parasitizing bats and marsupials; and in the state of Minas Gerais, Brazil, also parasitizing bats (Ali & Lovekar 1966;Quentin & Krishnasamy 1975;Spratt 1985Spratt , 2007.…”

Marmosa constantiae is a species of marsupial restricted to the central portion of South America. In Brazil, it occurs in the northwestern region including five states of the Amazon, Cerrado, and Pantanal biomes. However, there is no study of the helminth fauna or helminth community structure for this marsupial. The aims of this study were to describe the species composition and to analyse the structure of the helminthic community of M. constantiae in an area of the Amazon Arc in Sinop, north of the state of Mato Grosso, Brazil. Parasites were searched in 53 specimens of this marsupial, among which 44 were infected with at least one helminth species. Parasitic helminths were counted and identified. Nine species were collected: seven nematodes, one cestode, and one acanthocephalan. The most abundant species were Gracilioxyuris agilisis, Travassostrongylus scheibelorum, Pterygodermatites sinopiensis, and Subulura eliseae. These species were the only dominant ones in the component community. No significant differences were observed in the abundance and prevalence of helminths between male and female hosts. Host body size significantly influenced helminth abundance in males. The pattern of community structure considering the infracommunities in this locality indicated more species replacement than species loss along the environmental gradient. This is the first study to report the helminth fauna and the helminth community structure of M. constantiae.

“…In both instances, species have been identified in rodents (the cestode Bertiella anapolytica and the nematode Cyclodontostomum purvisi) which occur in Asia and in Australia (Beveridge and Spratt 1996). Additional examples of marsupial nematodes with an Asian distribution including parasites of bats are provided by Spratt (2007). For additional parasite groups, origins are either unknown or are contested, as is the case for the nematode subfamily Herpetostrongylinae with a South American origin proposed by Humphery-Smith (1983), an Asian origin suggested by Durette-Desset (1985) and the possibility of an origin in monotremes (echidnas) indicated by molecular data (Chilton et al 2015).…”

Wildlife parasitology is a highly diverse area of research encompassing many fields including taxonomy, ecology, pathology and epidemiology, and with participants from extremely disparate scientific fields. In addition, the organisms studied are highly dissimilar, ranging from platyhelminths, nematodes and acanthocephalans to insects, arachnids, crustaceans and protists. This review of the parasites of wildlife in Australia highlights the advances made to date, focussing on the work, interests and major findings of researchers over the years and identifies current significant gaps that exist in our understanding. The review is divided into three sections covering protist, helminth and arthropod parasites. The challenge to document the diversity of parasites in Australia continues at a traditional level but the advent of molecular methods has heightened the significance of this issue. Modern methods are providing an avenue for major advances in documenting and restructuring the phylogeny of protistan parasites in particular, while facilitating the recognition of species complexes in helminth taxa previously defined by traditional morphological methods. The life cycles, ecology and general biology of most parasites of wildlife in Australia are extremely poorly understood. While the phylogenetic origins of the Australian vertebrate fauna are complex, so too are the likely origins of their parasites, which do not necessarily mirror those of their hosts. This aspect of parasite evolution is a continuing area for research in the case of helminths, but remains to be addressed for many other parasitic groups.
