| morphological and molecular characterization of choleoeimeria pogonae n. sp. coccidian parasite (apicomplexa: eimeriidae, 1989, paperna and landsberg) in a western bearded dragon (pogona minor minor). | a new species, choleoeimeria pogonae n. sp. is described from a western bearded dragon (pogona minor minor) in western australia. sporulated oocysts (n = 48) were cylindroidal in shape. oocyst length, 27.0 (26.0-28.3) μm, oocyst width, 15.2 (14.0-16.5) μm, oocyst length/width ratio (l/w) 1.8 (1.6-1.9), each with 4 sporocysts (eimeria-like) and a polar granule, but lacking a micropyle and oocyst residuum. sporocysts are ovoidal in shape, sporocyst length, 10.0 (9.0-11.0) μm, sporocyst width 8.5 ( ... | 2016 | 26586629 |
| molecular detection of two adenoviruses associated with disease in australian lizards. | we give the first published description of the pathology and molecular findings associated with adenovirus infection in lizards in australia. a central netted dragon (ctenophorus nuchalis) exhibited severe necrotising hepatitis with abundant intranuclear inclusion bodies within hepatocytes and rarely within intestinal epithelial cells. polymerase chain reaction (pcr) using pooled tissues yielded an amplicon that shared strong nucleotide identity with an agamid adenovirus (eu914203). pcr on the l ... | 2011 | 21595645 |
| kidney function and the role of arginine vasotocin in three agamid lizards from habitats of differing aridity in western australia. | western australian agamid lizards are diverse and inhabit mesic to very arid areas of the state. although reptilian kidneys are unable to elaborate hyperosmotic urine, we hypothesised that the renal system of lizards inhabiting arid areas would display an enhanced ability to conserve water under the control of the antidiuretic peptide hormone, arginine vasotocin (avt). to examine this, the renal physiological and endocrine responses to osmotic challenge in three closely-related australian agamid ... | 2006 | 16423351 |
| identification of helodermatid adenovirus 2 in a captive central bearded dragon (pogona vitticeps), wild gila monsters (heloderma suspectum), and a death adder (acanthophis antarcticus). | adenoviruses are medium-sized dna viruses with very high host fidelity. the phylogenetic relationships of the adenoviruses strongly resemble that of their hosts, consistent with evolutionary codivergence. the genus atadenovirus appears to have evolved in squamate hosts. perhaps the best known of the squamate adenoviruses is agamid adenovirus 1 (agadv1), found most commonly in central bearded dragons (pogona vitticeps), where it is a prevalent cause of hepatitis/enteritis, especially in young ani ... | 2019 | 31120684 |
| niche modeling for the genus pogona (squamata: agamidae) in australia: predicting past (late quaternary) and future (2070) areas of suitable habitat. | as the climate warms, many species of reptiles are at risk of habitat loss and ultimately extinction. locations of suitable habitat in the past, present, and future were modeled for several lizard species using maxent, incorporating climatic variables related to temperature and precipitation. in this study, we predict where there is currently suitable habitat for the genus pogona and potential shifts in habitat suitability in the past and future. | 2018 | 30588407 |
