| blood parasites in reptiles imported to germany. | though international trade is increasing, the significance of imported reptiles as carriers of pathogens with relevance to animal and human health is largely unknown. reptiles imported to germany were therefore investigated for blood parasites using light microscopy, and the detected parasites were morphologically characterized. four hundred ten reptiles belonging to 17 species originating from 11 asian, south american and african countries were included. parasites were detected in 117 (29%) of ... | 2014 | 25324132 |
| devrieseasis in a plumed basilisk (basiliscus plumifrons) and chinese water dragons (physignathus cocincinus) in a zoologic collection. | devriesea agamarum is a gram-positive bacterium that was first described in 2008 as a causative agent of disease in lizards. until today, reports from several countries reported the presence of this bacterium in various lizard species, which suggests a wide distribution among lizard collections. pathologic lesions ranged from proliferative dermatitis and cheilitis to abscesses in multiple organs and septicemia in single animals, as well as entire groups. until now, disease caused by d. agamarum ... | 2016 | 27010288 |
| cerebral xanthomatosis in three green water dragons (physignathus cocincinus). | cerebral xanthomatosis was diagnosed in three female green water dragons (physignathus cocincinus), all of which presented with progressive neurologic signs. no antemortem evidence for xanthomatosis was identified, but on postmortem examination cholesterol granulomas, composed of cholesterol clefts surrounded by macrophages and multinucleated giant cells, were found in the forebrain of each animal and were associated with significant displacement and pressure on the adjacent brain. although the ... | 2010 | 20722265 |
| mitochondrial genome of pogona vitticepes (reptilia; agamidae): control region duplication and the origin of australasian agamids. | the complete mitochondrial dna sequence for an australian agamid pogona vitticepes was determined. twenty-two trna genes, two rrna genes, thirteen protein-coding genes, and two control regions were identified in this mitochondrial genome. the second control region was inserted between nadh dehydrogenase subunits 5 and 6 genes. the duplication of the control region was found in all australasian agamids examined and was not found in other asian or african taxa. the two control regions had nearly i ... | 2005 | 15716001 |
| evaluating trans-tethys migration: an example using acrodont lizard phylogenetics. | a phylogenetic tree for acrodont lizards (chamaeleonidae and agamidae) is established based on 1434 bases (1041 informative) of aligned dna positions from a 1685-1778 base pair region of the mitochondrial genome. sequences from three protein-coding genes (nd1, nd2, and coi) are combined with sequences from eight intervening trna genes for samples of 70 acrodont taxa and two outgroups. parsimony analysis of nucleotide sequences identifies eight major clades in the acrodonta. most agamid lizards a ... | 2000 | 12118407 |
| parthenogenesis in a captive asian water dragon (physignathus cocincinus) identified with novel microsatellites. | reptiles show varying degrees of facultative parthenogenesis. here we use genetic methods to determine that an isolated, captive female asian water dragon produced at least nine offspring via parthenogenesis. we identified microsatellites for the species from shotgun genomic sequences, selected and optimized primer sets, and tested all of the offspring for a set of seven microsatellites that were heterozygous in the mother. we verified that the seven loci showed high levels of polymorphism in fo ... | 2019 | 31166974 |
