“…A common species infecting American marsupials and described as Hepatozoon didelphydis was recently found to be a Sarcocystidae (Merino et al, 2008), and a similar case has been recently reported for a marsupial species in Australia (Zhu et al, 2009). Criado-Fornelio et al (2006) failed to find Hepatozoon infections in 15 opossums (Didelphis albiventris) from Brazil either by molecular methods or microscopy, in contrast to the 25% prevalence detected by microscopy in the same species from French Guyana (de Thoisy et al, 2000).…”

“…Hepatozoon infections have also been reported infecting other neotropical marsupials, including Didelphys marsupialis, Philander opossum, and Metachirus nudicaudatus (d'Utra e Silva & Arantes, 1916;Regendanz & Kikuth, 1928;Garnham & Lewis, 1958;Deane & Deane, 1961;Ayala et al, 1973). However, these reports are only based in microscopy and some of them are attributed to H. didelphydis, and may correspond to infections by an erythrocytic sarcocystidae (Merino et al, 2008).…”

The Microbiotheriid Dromiciops gliroides, also known as 'Monito del Monte', is considered to be a threatened species and the only living representative of this group of South American marsupials. During the last few years, several blood samples from specimens of 'Monito del Monte' captured at Chiloé island in Chile have been investigated for blood parasites. Inspection of blood smears detected a Hepatozoon species infecting red blood cells. The sequences of DNA fragments corresponding to small subunit ribosomal RNA gene revealed two parasitic lineages belonging to Hepatozoon genus. These parasite lineages showed a basal position with respect to Hepatozoon species infecting rodents, reptiles, and amphibians but are phylogenetically distinct from Hepatozoon species infecting the order Carnivora. In addition, the Hepatozoon lineages infecting D. gliroides are also different from those infecting other micro-mammals living in sympatry, as well as from some that have been described to infect an Australian species of bandicoot. The potential vector of this parasite appears to be the host-specific tick Ixodes neuquenensis because the sequencing of a long amplicon determined the presence of one of the two lineages found in the marsupial.

Disseminated protozoal infection in a wild feathertail glider (Acrobates pygmaeus) in Australia

This is the first report of a disseminated protozoal infection in a wild feathertail glider ( Acrobates pygmaeus ) from south-eastern Australia. The glider was found dead in poor body condition. Histologically, large numbers of zoites were seen predominantly in macrophages in the liver, spleen and lung, with protozoal cysts present in the liver. Molecular and phylogenetic analyses inferred that the protozoan parasite belongs to the family Sarcocystidae and is closely related to previously identified apicomplexans found in yellow-bellied gliders ( Petaurus australis ) in Australia and southern mouse opossums ( Thylamys elegans ) in Chile.

With regard to wildlife translocations and the assessment of potential risk of disease transmission, several advances have been made in conservative projects. However, other factors like the large number of species received at screening centers from different locations, rescued after being hit by vehicles, taken by the public or confiscated from illegal trade by the authorities, have increased the risk of spreading, emergence or reemergence of zoonosis. Besides the notorious importance of the procedure improvement for managing wildlife, the access to as much as possible information about the occurrence of potential infections on each particular species can be a tool of great value for mitigating the disease risk. In the present paper, it was showed the evolution of processes for wildlife translocations mostly related to mammals, we also discussed some aspects related to sylvatic animals as reservoir host of zoonosis and finally were presented several tables recording numerous mammals hosts and their respective parasitic protozoa.
