| structure and similarity of helminth communities of six species of australian turtles. | patterns of infracommunity structure and infra- and component community similarity were examined for helminths of 6 species of turtles, each collected from a single locality in australia in 1993 and 1994. elseya latisternum (n = 11) and emydura kreffti (n = 16) were collected from northern queensland, emydura macquarii macquarii (n = 11) from southern queensland, emydura macquarii dhara (n = 11) and chelodina longicollis (n = 11) from northern new south wales, and chelodina oblonga (n = 5) from ... | 2008 | 18576816 |
| a new species of freshwater turtle of the genus elseya (testudinata: pleurodira: chelidae) from the northern territory of australia. | the genus elseya has had a checkered taxonomic history, but is now restricted to species characterized by an alveolar ridge on the triturating surfaces of the jaw. the australian forms were once regarded as a single widespread species extending from the mary river of south-eastern queensland to the fitzroy river of north western australia, but a number of australian species have now been identified based on a combination of molecular and morphological data-elseya dentata, e. irwini, e. lavaracko ... | 2016 | 27395476 |
| phylogenetic relationships of hepatozoon (haemogregarina) boigae, hepatozoon sp., haemogregarina clelandi and haemoproteus chelodina from australian reptiles to other apicomplexa based on cladistic analyses of ultrastructural and life-cycle characters. | the phylogeny of representative haemozoan species of the phylum apicomplexa was reconstructed by cladistic analyses of ultrastructural and life-cycle characteristics. the analysis incorporated 4 apicomplexans previously not included in phylogenetic reconstructions: haemogregarina clelandi from the brisbane river tortoise (emydura signata), hepatozoon sp. from the slaty grey snake (stegonotus cucullatus), hepatozoon (haemogregarina) boigae from the brown tree snake (boiga irregularis), and haemop ... | 2003 | 12866793 |
| hemoprotozoa of freshwater turtles in queensland. | blood smears from 27 turtles (15 emydura signata, nine elseya latisternum, and three chelodina longicollis) from southeastern queensland (australia) were examined for infections by hemoprotozoan parasites between january and june 1999. infections were found in 26 (96%) of the turtles. twenty five (93%) were infected with the adeleorin coccidian haemogregarina clelandi, eight (30%) with the hemosporidian haemoproteus chelodinae, 11 (41%) with the kinetoplastid flagellate trypanosoma chelodinae, a ... | 2001 | 11272486 |
| phylogenetic relationships of trypanosoma chelodina and trypanosoma binneyi from australian tortoises and platypuses inferred from small subunit rrna analyses. | trypanosome infections are often difficult to detect by conventional microscopy and their pleomorphy often confounds differential diagnosis. molecular techniques are now being used to diagnose infections and to determine phylogenetic relationships between species. complete small subunit rrna gene sequences were determined for isolates of trypanosoma chelodina from the brisbane river tortoise (emydura signata), the saw-shelled tortoise (elseya latisternum), and the eastern snake-necked tortoise ( ... | 2001 | 11719959 |
| pathogenicity in six australian reptile species following experimental inoculation with bohle iridovirus. | ranaviruses are able to infect multiple species of fish, amphibian and reptile, and some strains are capable of interclass transmission. these numerous potential carriers and reservoir species compound efforts to control and contain infections in cultured and wild populations, and a comprehensive knowledge of susceptible species and life stage is necessary to inform such processes. here we report on the challenge of 6 water-associated reptiles with bohle iridovirus (biv) to investigate its poten ... | 2015 | 26290505 |
| serological survey of australian native reptiles for exposure to ranavirus. | ranaviruses have been isolated from many ectothermic vertebrates, and serological surveys of both amphibians and reptiles have shown the presence of ranaviral antibodies in a proportion of these populations. an enzyme-linked immunosorbent assay (elisa) was developed to measure serum antibodies against ranavirus in australian reptiles. the elisa was validated with serum from challenge trials with bohle iridovirus (biv) in 6 reptilian species. a preliminary sero-survey of northern queensland ripar ... | 2017 | 29160216 |
| description of auriculotrema lechneri n. gen., n. sp. (digenea: choanocotylidae), a parasite of freshwater turtles (testudines: pleurodira: chelidae) from queensland, australia. | auriculotrema lechneri n. gen., n. sp. is described from the small intestine of emydura krefftii and elseya latisternum from northern queensland, australia. the new species strongly resembles species of choanocotyle in body shape, ventral incision of the oral sucker, structure of the cirrus sac, and location of the genital pore. the distinctive taxonomic feature is the presence of 2 winglike projections extending beyond the lateral margins of the oral sucker, in contrast to the extremely large, ... | 2003 | 12659317 |
| a redescription of the australian leech placobdelloides bancrofti with new records of its distribution. | placobdelloides bancrofti (best, 1931) sawyer, 1986 (euhirudinea: glossiphoniidae) is recorded for the first time from a location in north queensland, australia. placobdelloides bancrofti was found feeding on the freshwater turtle emydura krefftii and was collected from a new host species elseya latisternum. examination of live individuals enabled us to document external coloration and markings for the first time. clarification of the original description of p. bancrofti is made, correcting the ... | 2005 | 15856883 |
| two new species of camallanus (nematoda: camallanidae) from freshwater turtles in queensland, australia. | we describe 2 new species of camallanus (nematoda: camallanidae) from freshwater turtles collected in queensland, australia: camallanus nithoggi n. sp. from elseya latisternum (gray) and camallanus waelhreow n. sp. from emydura krefftii (gray), emydura macquarrii (gray), and em. macquarrii dharra cann. the only camallanus sp. previously reported from turtles is c. chelonius baker, 1983 (all other species in the family have been transferred to serpinema). the 2 new species described here differ f ... | 2008 | 19127966 |
