| epidemiology and control of anaplasmosis in australia. | anaplasmosis occurs in those areas of northern and eastern australia infested by the cattle tick boophilus microplus but it has been studied intensively only in queensland. anaplasmosis is predominantly a disease of autumn and winter and of cattle greater than 1 year of age. the complement fixation test has been used in serological surveys of the tick-infested areas of the state. both clinical and subclinical infections occur only in tick-infested areas and they are both more frequent in bos tau ... | 1979 | 553977 |
| development, survival, fecundity and behaviour of haemaphysalis (kaiseriana) longicornis (ixodidae) at two locations in southeast queensland. | the free-living stages of the tick haemaphysalis (kaiseriana) longicornis were studied at mt tamborine (526 m altitude) and amberley (25 m altitude) in southeast queensland between 1971 and 1980. data are presented on the number of eggs and larvae produced, the moulting success of engorged larvae and nymphs and the survival and behaviour of unfed larvae, nymphs and adult females. temperature, moisture, daylength, grass length and age of unfed ticks were investigated as sources of variation in de ... | 1991 | 1757193 |
| the numbers of bush ticks, haemaphysalis longicornis, parasitic on grazing cattle before and after the acquisition of host resistance. | the numbers of bush ticks, haemaphysalis longicornis, on bos taurus steers in south east queensland was recorded regularly from july 1971 until january 1974. the steers had no prior exposure to the tick. the parasitic tick population was large during the first year, but declined to low levels in the second and third years, apparently as a result of the steers acquiring resistance to tick feeding. | 1983 | 6681952 |
| flinders island spotted fever rickettsioses caused by "marmionii" strain of rickettsia honei, eastern australia. | australia has 4 rickettsial diseases: murine typhus, queensland tick typhus, flinders island spotted fever, and scrub typhus. we describe 7 cases of a rickettsiosis with an acute onset and symptoms of fever (100%), headache (71%), arthralgia (43%), myalgia (43%), cough (43%), maculopapular/petechial rash (43%), nausea (29%), pharyngitis (29%), lymphadenopathy (29%), and eschar (29%). cases were most prevalent in autumn and from eastern australia, including queensland, tasmania, and south austral ... | 2007 | 17553271 |
| parasites of the brush-tailed rock-wallaby (petrogale penicillata). | the brush-tailed rock-wallaby (petrogale penicillata) is listed as vulnerable on the international union for conservation of nature (iucn) red list of threatened species. parasitic diseases have been proposed as possible contributing factors to the decline of the species, but very little is known about the effects of parasites on this host. this study determined the antibody prevalence of the protist toxoplasma gondii in a wild brush-tailed rock-wallaby population from three neighboring colonies ... | 2010 | 20090035 |
