| some effects of tick infestations on juvenile northern brown bandicoot (isoodon macrourus). | the effect of tick infestations on body weight and various blood parameters was monitored in juvenile northern brown bandicoots (isoodon macrourus) after release into tick-infested or tick-free enclosures. three species of ticks were observed in the enclosures, haemaphysalis humerosa, ixodes tasmani and ixodes holocyclus. bandicoots released into tick-infested enclosures showed a reduced growth rate (1.8 versus 2.5 g/day increase in body weight), a reduced haematocrit value (27.4 versus 40.0%) a ... | 1991 | 2067048 |

| q fever. | q fever is a zoonosis with a worldwide distribution with the exception of new zealand. the disease is caused by coxiella burnetii, a strictly intracellular, gram-negative bacterium. many species of mammals, birds, and ticks are reservoirs of c. burnetii in nature. c. burnetii infection is most often latent in animals, with persistent shedding of bacteria into the environment. however, in females intermittent high-level shedding occurs at the time of parturition, with millions of bacteria being r ... | 1999 | 10515901 |
| development of an indirect tams1 enzyme-linked immunosorbent assay for diagnosis of theileria annulata infection in cattle. | an enzyme-linked immunosorbent assay (elisa) was developed based on a recombinant major theileria annulata merozoite surface antigen, tams1. four different recombinant proteins derived from two different tams1 alleles, both in two different truncated forms, were tested for their performance in the elisa. furthermore, antigen concentration, various buffers, washing protocol, and the choice of anti-total-immunoglobulin g (igg), anti-igg1, or anti-igg2 as second antibody were evaluated. the perform ... | 2000 | 10799453 |
| evolution of the secondary structure of the rrna internal transcribed spacer 2 (its2) in hard ticks (ixodidae, arthropoda). | its2 sequences are used extensively in molecular taxonomy and population genetics of arthropods and other animals yet little is known about the molecular evolution of its2. we studied the secondary structure of its2 in species from each of the six main lineages of hard ticks (family ixodidae). the its2 of these ticks varied in length from 679 bp in ixodes scapularis to 1547 bp in aponomma concolor. nucleotide content varied also: the its2 of ticks from the prostriata lineage (ixodes spp.) had 46 ... | 2002 | 11920135 |
| Coxiella burnetii in Western Barred Bandicoots (Perameles bougainville) from Bernier and Dorre Islands in Western Australia. | The aim of this work is to investigate the presence of Coxiella burnetii in Perameles bougainville and their ticks on two islands off Western Australia. Haemaphysalis humerosa, Haemaphysalis ratti, and Haemaphysalis lagostrophi were collected from P. bougainville on Bernier and Dorre Islands from 2005 to 2007; only Amblyomma limbatum was collected from humans over the same interval. One of 13 tick samples and 1 of 12 P. bougainville fecal samples were positive for C. burnetii DNA using quantitat ... | 2011 | 22167449 |
| novel borrelia species detected in echidna ticks, bothriocroton concolor, in australia. | to date, little has been documented about microorganisms harboured within australian native ticks or their pathogenic potential. recently, a borrelia sp. related to the relapsing fever (rf) group was identified in a single tick removed from a wild echidna (tachyglossus aculeatus). the present study investigated the presence of borrelia in 97 bothriocroton concolor ticks parasitizing echidnas in queensland, new south wales, and victoria, australia, using nested pcr with borrelia-specific primers ... | 2016 | 27301754 |
| update on tick-borne rickettsioses around the world: a geographic approach. | tick-borne rickettsioses are caused by obligate intracellular bacteria belonging to the spotted fever group of the genus rickettsia. these zoonoses are among the oldest known vector-borne diseases. however, in the past 25 years, the scope and importance of the recognized tick-associated rickettsial pathogens have increased dramatically, making this complex of diseases an ideal paradigm for the understanding of emerging and reemerging infections. several species of tick-borne rickettsiae that wer ... | 0 | 24092850 |
