Genome sequence of Rickettsia australis, the agent of Queensland tick typhus.
نویسندگان
چکیده
Rickettsia australis strain Phillips(T) was isolated in Queensland, Australia, in 1950. It is the tick-borne agent of Queensland tick typhus, a disease endemic in Australia. The 1.29-Mb genome sequence of this bacterium is highly similar to that of Rickettsia akari but contains two plasmids.

Epidemiology and Characteristics of Rickettsia australis (Queensland Tick Typhus) Infection in Hospitalized Patients in North Brisbane, Australia
Queensland tick typhus (QTT; Rickettsia australis) is a spotted fever group (SFG) rickettsial infection endemic to Australia. It is an underreported and often unrecognized illness with poorly-defined epidemiology. This article describes epidemiological features and the geographical distribution of QTT in hospitalized patients. Cases of QTT were identified retrospectively from 2000–2015 at five ...
متن کاملSevere Spotted Fever Group Rickettsiosis, Australia
We report 3 cases of spotted fever group rickettsial infection (presumed Queensland tick typhus) in residents of northern Queensland, Australia, who had unusually severe clinical manifestations. Complications included renal failure, purpura fulminans, and severe pneumonia. Clinical illness caused by Rickettsia australis may not be as benign as previously described.

We report 3 rickettsioses on Darnley Island, Australia, in the Torres Strait. In addition to previously described cases of Flinders Island spotted fever (Rickettsia honei strain "marmionii"), we describe 1 case of Queensland tick typhus (R. australis) and 2 cases of scrub typhus caused by a unique strain (Orientia tsutsugamushi).
متن کاملSpotted Fevers
Spotted fevers, which are caused by Rickettsia spp. in the spotted fever group (SFG), have been recognized in people for more than a hundred years. The clinical signs are broadly similar in all of these diseases, but the course ranges from mild and self-limited to severe and life-threatening. For a long time, spotted fevers were thought to be caused by only a few organisms, including Rickettsia...
متن کاملEvidence of a spotted fever-like rickettsia and a potential new vector from northeastern Australia.
A spotted fever-like rickettsia was identified in a Hemaphysalis tick by polymerase chain reaction (PCR) amplification and sequencing of the 16S rDNA, ompA, and ompB genes. A comparison of these nucleotide sequences with those of other spotted fever group (SFG) rickettsiae revealed that the Hemaphysalis tick rickettsia ia was distinct from other previously reported strains. Phylogenetic analysi...
