ultrasonographic appearance of the coelomic cavity organs in healthy veiled chameleons (chamaeleo calyptratus) and panther chameleons (furcifer pardalis).veiled chameleons (chamaeleo calyptratus) and panther chameleons (furcifer pardalis) are the most popular chameleons over the world, and consequently, two of the most frequent species presenting to veterinary practices. however, published studies on normal ultrasonographic anatomy for these lizards are currently lacking. the objectives of this prospective anatomic study were to develop an ultrasound protocol for evaluation of the coelomic cavity in these species and describe the normal ultrasono ...202031794122
on caudal prehensility and phylogenetic constraint in lizards: the influence of ancestral anatomy on function in corucia and furcifer.we examined caudal anatomy in two species of prehensile-tailed lizards, furcifer pardalis and corucia zebrata. although both species use their tails to grasp, each relies on a strikingly different anatomy to do so. the underlying anatomies appear to reflect phylogenetic constraints on the consequent functional mechanisms. caudal autotomy is presumably the ancestral condition for lizards and is allowed by a complex system of interdigitating muscle segments. the immediate ancestor of chameleons wa ...199929847883
fungal dermatitis, glossitis and disseminated visceral mycosis caused by different metarhizium granulomatis genotypes in veiled chameleons (chamaeleo calyptratus) and first isolation in healthy lizards.metarhizium (m.) granulomatis (formerly chamaeleomyces granulomatis) invariably causes fatal fungal glossitis and systemic mycosis in veiled chameleons (chamaeleo calyptratus). isolation of m. granulomatis in other lizards thus far has not been described. the aim of this study therefore was to obtain information on the presence of m. granulomatis in reptiles kept as pets, and to examine whether there was an association between specific genotypes and clinical/pathological outcomes. besides 18s ri ...201728757044
characterization of metarhizium viride mycosis in veiled chameleons (chamaeleo calyptratus), panther chameleons (furcifer pardalis), and inland bearded dragons (pogona vitticeps).metarhizium viride has been associated with fatal systemic mycoses in chameleons, but subsequent data on mycoses caused by this fungus in reptiles are lacking. the aim of this investigation was therefore to obtain information on the presence of m. viride in reptiles kept as pets in captivity and its association with clinical signs and pathological findings as well as improvement of diagnostic procedures. beside 18s ribosomal dna (rdna) (small subunit [ssu]) and internal transcribed spacer region ...201728003420
the colour of success: does female mate choice rely on male colour change in the chameleon furcifer pardalis?colour change is involved in various functions ranging from thermo- and hydroregulation to camouflage and communication. the role of colour change in communication has received increased attention over the past few decades, yet has been studied predominantly in the context of intrasexual competition. here, we investigate the role of colour change in mate choice in an animal that can change its colour, the panther chameleon (furcifer pardalis). we conducted behavioural experiments and colour anal ...202032843362
female heterogamety in madagascar chameleons (squamata: chamaeleonidae: furcifer): differentiation of sex and neo-sex chromosomes.amniotes possess variability in sex determining mechanisms, however, this diversity is still only partially known throughout the clade and sex determining systems still remain unknown even in such a popular and distinctive lineage as chameleons (squamata: acrodonta: chamaeleonidae). here, we present evidence for female heterogamety in this group. the malagasy giant chameleon (furcifer oustaleti) (chromosome number 2nā€‰=ā€‰22) possesses heteromorphic z and w sex chromosomes with heterochromatic w. t ...201526286647
cutaneous squamous cell carcinoma in a panther chameleon (furcifer pardalis) and treatment with carboplatin implantable beads.a 3-yr-old male panther chameleon (furcifer pardalis) presented with bilateral raised crusted skin lesions along the lateral body wall that were found to be carcinoma in situ and squamous cell carcinoma. similar lesions later developed on the caudal body wall and tail. a subcutaneous implantable carboplatin bead was placed in the first squamous cell carcinoma lesion identified. additional new lesions sampled were also found to be squamous cell carcinomas, and viral polymerase chain reaction was ...201627691962
panther chameleons, furcifer pardalis, behaviorally regulate optimal exposure to uv depending on dietary vitamin d3 status.reptiles may bask for reasons other than thermoregulation. one alternative is to regulate homeostasis of vitamin d(3), a hormone essential to the health of many reptiles. maintenance of vitamin d(3) homeostasis requires either regulation of exposure to ultraviolet radiation (uv) or ingested vitamin d(3). however, the prey items of most vertebrates tend to be low in vitamin d(3). thus, basking may be the primary opportunity for vitamin d(3) regulation. we tested the hypothesis that panther chamel ...201319335229

phylogeography and support vector machine classification of colour variation in panther chameleons.lizards and snakes exhibit colour variation of adaptive value for thermoregulation, camouflage, predator avoidance, sexual selection and speciation. furcifer pardalis, the panther chameleon, is one of the most spectacular reptilian endemic species in madagascar, with pronounced sexual dimorphism and exceptionally large intraspecific variation in male coloration. we perform here an integrative analysis of molecular phylogeography and colour variation after collecting high-resolution colour photog ...201526011002
plasma biochemistry and hematology reference values of captive panther chameleons (furcifer pardalis) with special emphasis on seasonality and gender differences.blood samples of 86 captive panther chameleons (furcifer pardalis) were collected in january and august from the ventral coccygeal vein in order to establish reference intervals of clinical healthy individuals under similar husbandry conditions for plasma biochemistry and hematology for this species. significant differences were found in phosphorus, glucose, total protein, albumin, and white blood cell count between males and females in both seasons. calcium, alanine aminotransferase, aspartate ...201627691946
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 ...201425324132
detection and phylogenetic analysis of a new adenoviral polymerase gene in reptiles in korea.over a period of 7 years (2004-2011), samples from 34 diseased reptiles provided by local governments, zoos, and pet shops were tested for viral infection. animals were diagnosed based on clinical signs, including loss of appetite, diarrhea, rhinorrhea, and unexpected sudden death. most of the exotic animals had gastrointestinal problems, such as mucosal redness and ulcers, while the native animals had no clinical symptoms. viral sequences were found in seven animals. retroviral genes were ampli ...201829460003
expanding the host range: infection of a reptilian host (furcifer pardalis) by an atypical brucella strain.atypical brucellae show deviant phenotypes and/or genotypes. besides brucella inopinata, b. microti and b. vulpis, atypical strains have been described infecting humans, rodents, amphibians and fish. they represent potential zoonotic agents. here, we provide evidence that reptiles as the remaining poikilothermic vertebrate class also represent susceptible hosts for atypical brucella.202032699967
five new species of coccidia (apicomplexa: eimeriidae) from madagascan chameleons (sauria: chamaeleonidae).coprological examination of 19 madagascan chameleons of the genera furcifer and brookesia revealed the presence of five new coccidian species. isospora brygooi n. sp. from furcifer pardalis has spherical to subspherical oöcysts with a slightly pitted wall, 20.7 (17-24.5) x 19.3 (16-23) microm and broadly ellipsoidal sporocysts, 12.2 (11.5-13) x 8.1 (8-8.5) microm, with stieda and substieda bodies. oöcysts of eimeria glawi n. sp. from furcifer pardalis are cylindrical to ellipsoidal, 27.7 (26-29. ...200111252274
