Tissue distribution of Coxiella burnetii and antibody responses in macropods co-grazing with livestock in Queensland, Australia.

Coxiella burnetii, the causative agent of Q fever, is a zoonotic bacteria of global public health significance. The organism has a complex, diverse, and relatively poorly understood animal reservoir but there is increasing evidence that macropods play some part in the epidemiology of Q fever in Australia. The aim of this cross-sectional survey was to estimate the animal- and tissue-level prevalence of coxiellosis amongst eastern grey (Macropus giganteus) and red (Osphranter rufus) kangaroos co-grazing with domestic cattle in a Q fever endemic area in Queensland.

A Novel Marine Mammal -Genome Sequencing Identifies a New Genotype with Potential Virulence.

The obligate intracellular bacterial pathogen has been identified in a few species of marine mammals, some of which are showing population declines. It has been hypothesized that in marine mammals is a distinct genotype that varies significantly from the typical terrestrial genotypes. It appears to lack an IS1111.

Unravelling the Diversity of Microorganisms in Ticks from Australian Wildlife.

Ticks and tick-borne pathogens pose a significant threat to the health and welfare of humans and animals. Our knowledge about pathogens carried by ticks of Australian wildlife is limited. This study aimed to characterise ticks and tick-borne microorganisms from a range of wildlife species across six sites in Victoria, Australia.

Pacific Gulls () as Potential Vectors of in an Australian Fur Seal Breeding Colony.

Recently, has been described as a novel pathogen potentially contributing to decreased pup production in Australian fur seals (AusFS, ). Pacific gulls (PGs, ) are known to scavenge AusFS placental material during the fur seal breeding season. It is hypothesized that PGs may act as vectors for this pathogen.

Scrub Typhus and Molecular Characterization of from Central Nepal.

Scrub typhus is a vector-borne, acute febrile illness caused by . Scrub typhus continues to be an important but neglected tropical disease in Nepal. Information on this pathogen in Nepal is limited to serological surveys with little information available on molecular methods to detect .

Molecular Evidence of Novel Spotted Fever Group Species in Ticks from the Shingleback Skink () in Southern Western Australia.

Tick-borne infectious diseases caused by obligate intracellular bacteria of the genus are a growing global problem to human and animal health. Surveillance of these pathogens at the wildlife interface is critical to informing public health strategies to limit their impact. In Australia, reptile-associated ticks such as are the reservoirs for , the causative agent of Flinders Island spotted fever.

Screening for , and Species in Ticks from Queensland, Australia.

Tick bites in Australia are linked to the transmission of a variety of infectious diseases in humans, livestock and wildlife. Despite this recognition, little is currently known about the variety of potential pathogens that are carried and transmitted by Australian ticks. In this study, we attempted to expand knowledge of Australian tick-borne bacterial pathogens by analyzing various tick species from the state of Queensland for potential human pathogens belonging to the , and genera.

Molecular detection of Coxiella burnetii in raw meat intended for pet consumption.

The discovery of antibodies against Coxiella burnetii in cattery-confined breeding cats indicating prior or current exposure (Shapiro et al., 2015) prompted an investigation into possible sources of infection. One hypothesis was that raw meat diets containing reservoir species may provide a source of C.

Development and comparative evaluation of a competitive ELISA with rose bengal test and a commercial indirect ELISA for serological diagnosis of brucellosis.

The development of a competitive ELISA for the detection of brucella-specific antibodies in bovines is described. Anti-brucella guinea pig serum was used as a source of competing antibodies. Lipo-polysaccharide purified from inactivated B.
