It is confirmed that species of Amblyomma harbor DNA of the same Hepatozoon species detected in the water pythons, and the detection of an additional genotype suggests the ticks may be exposed to 2 HepatoZoon species, providing further opportunity to study multiple host–vector–parasite relationships.

These results represent the first detection of the three genera in each tick species and identify a high level of previously undetected bacterial diversity in Australian ticks.
Development of the immune system and immunological protection in marsupial pouch young.

Ticks collected from five wild-caught reptile species during routine trapping in the Djukbinj National Park and Fogg Dam Reserve, Northern Territory, Australia revealed the presence of a Francisella species closely related to other tick-borne Francisellae identified in ticks from the Northern Hemisphere.

Developmental adjustment mechanisms of the ‘catch-up hypothesis’ for synchronous hatching in E. macquarii imply some level of embryo–embryo communication and the group environment of a nest strongly supports the development of adaptive communication mechanisms between siblings and the evolution of environmentally cued hatching.

Low numbers or absence of mature lymphocytes in immune tissues of early pouch young dunnarts further support the proposition that young marsupials are reliant on non‐specific defence strategies and/or maternal strategies for a significant period of their time of development in the pouch.
The detection of mature T‐ and B‐cells during development of the lymphoid tissues of the tammar wallaby (Macropus eugenii)
The detection of apparently mature T‐ and B‐cells in the thymus and gut‐associated lymphoid tissues (GALT) at the same postnatal age highlights the need for a more substantial study of the development of GALT.
The effect of oestrus and the presence of pouch young on aerobic bacteria isolated from the pouch of the tammar wallaby, Macropus eugenii.
Detection of a Hepatozoon and spotted fever group Rickettsia species in the common marsupial tick (Ixodes tasmani) collected from wild Tasmanian devils (Sarcophilus harrisii), Tasmania.

Analysis of partial sequences for the gltA gene indicated the presence of a Bartonella-related species similar to that reported in another Ixodid species, the first report of Bartoneella-like organisms in a native Australian marsupial.
