Reptiles are tetrapod animals in the class Reptilia, comprising today's turtles, crocodilians, snakes, amphisbaenians, lizards, tuatara, and their extinct relatives. The study of these traditional reptile orders, historically combined with that of modern amphibians, is called herpetology.
Colubridae is a family of snakes. With 524 genera and approximately 1,760 species, it is the largest snake family, and includes just over 51% of all known living snake species. The earliest species of the family date back to the Oligocene epoch. Colubrid snakes are found on every continent except Antarctica.
A conidium, sometimes termed an asexual chlamydospore or chlamydoconidium, is an asexual, non-motile spore of a fungus. The name comes from the Greek word for dust, κόνις kónis. They are also called mitospores due to the way they are generated through the cellular process of mitosis. The two new haploid cells are genetically identical to the haploid parent, and can develop into new organisms if conditions are favorable, and serve in biological dispersal.
Toxicofera is a proposed clade of scaled reptiles (squamates) that includes the Serpentes (snakes), Anguimorpha and Iguania. Toxicofera contains about 4,600 species, of extant squamata. It encompasses all venomous reptile species, as well as numerous related non-venomous species. There is little morphological evidence to support this grouping, however it has been recovered by all recent molecular analyses.
Chaetothyriales is an order of ascomycetous fungi within the class Eurotiomycetes and within the subphylum Pezizomycotina. A disease entity that is largely confined to Chaetothyriales is primary cerebral infection in immunocompromised or immunocompetent individuals, i.e., cerebritis in which the first symptoms of disease are of a neurologic nature. Hyphal elements that show melanization either directly or after Fontana-Masson staining are observed in abscesses in the brain parenchyma. The portal of entry may be the lung, but frequently symptoms are confined to the brain. Five species account for most nontraumatic brain infections. Cladophialophora bantiana has caused about one-third of the cases in otherwise healthy individuals.
Botryosphaeria dothidea Ces. & De Not. is a plant pathogen that causes the formation of cankers on a wide variety of tree and shrub species. It has been reported on several hundred plant hosts and on all continents except Antarctica. B. dothidea was redefined in 2004, and some reports of its host range from prior to that time likely include species that have since been placed in another genus. Even so, B. dothidea has since been identified on a number of woody plants—including grape, mango, olive, eucalyptus, maple, and oak, among others—and is still expected to have a broad geographical distribution. While it is best known as a pathogen, the species has also been identified as an endophyte, existing in association with plant tissues on which disease symptoms were not observed. It can colonize some fruits, in addition to woody tissues.
Dinosauriformes is a clade of archosaurian reptiles that include the dinosaurs and their most immediate relatives. All dinosauriformes are distinguished by several features, such as shortened forelimbs and a partially to fully perforated acetabulum, the hole in the hip socket traditionally used to define dinosaurs. The oldest known member is Asilisaurus, dating to about 245 million years ago in the Anisian age of the middle Triassic period.
The Alethinophidia are an infraorder of snakes that includes all snakes other than blind snakes and thread snakes. Snakes have long been grouped into families within Alethinophidia based on their morphology, especially that of their teeth. More modern phylogenetic hypotheses using genetic data support the recognition of 19 extant families, although the taxonomy of alethinophidian snakes has long been debated, and ultimately the decision whether to assign a particular clade to a particular Linnaean rank is arbitrary.
Chlamydosauromyces punctatus is the sole species in the monotypic genus of fungi, Chlamydosauromyces in the family, Onygenaceae. It was found in the skin shed from frilled lizard. This fungus is mesophilic and digests hair. It reproduces both sexually and asexually. The fungus has so far not been reported to be pathogenic.
Nannizziopsis vreisii is a keratinophilic microfungus in the Family Onygenaceae of the order Onygenales. Also included in this family are dematophytes and saprophytic species. While the ecology of N. vriessi is not well known, there has been several studies which identifies the Chrysosporium anamorph of N. vriesii as a causal agent of skin lesions in reptiles across several regions. This species is usually identified under a microscope by its white ascomata, and hyaline and globose ascopores. Like many other fungi, N. vreisii has a sexual and asexual state, the asexual states are classified as the genus Chryososporium, Malbranchea or Sporendonema.
The Lamprophiidae are a family of snakes found mostly in Africa, but also in parts of southern Europe and western Asia. A few species reach southeastern Asia. There are 322 species as of April 2019.
Chrysosporium longisporum is a keratinophilic microfungus in the family Onygenaceae that causes skin infections in reptiles, producing hyaline, thin-walled, small, sessile conidia and colonies with a strong skunk-like odour.
Nannizziopsis arthrosporioides is a keratinophilic microfungus in the family Onygenaceae that causes skin infections in reptiles, producing hyaline, thin-walled, small, sessile conidia and colonies with a strong skunk-like odour. It is distinguished by the production of long arthroconidia.
Nannizziopsis draconii is a keratinophilic microfungus in the family Onygenaceae that causes skin infections in reptiles, producing hyaline, thin-walled, small, sessile conidia and colonies with a strong skunk-like odour.
Nannizziopsis chlamydospora is a keratinophilic microfungus in the family Onygenaceae that causes skin infections in reptiles, producing hyaline, thin-walled, small, sessile conidia and colonies with a strong skunk-like odour. This species is distinguished by producing chlamydospores and its ability to grow at 5 °C.
Ophidiomyces ophiodiicola is a keratinophilic fungus from the family Onygenaceae of the order Onygenales. O. ophiodiicola is an emerging pathogen of captive and wild snakes in North America. It is reported to cause snake fungal disease (SFD) in many different species of snakes; clinical signs include skin swelling, crusts, and nodules of the skin. The mode of transmission is unknown, but is speculated to occur with direct contact between snakes or with the contaminated environment. Currently no treatment for O. ophiodiicola is available. O. ophiodiicola was identified by Sigler, Hambleton & Paré in 2013. O. ophiodiicola is the only species in the genus Ophidiomyces. It was previously known as Chrysosporium ophiodiicola and is closely related to Chrysosporium anamorph Nannizziopsis vriesii (CANV).
Fonsecaea compacta is a saprophytic fungal species found in the family Herpotrichiellaceae. It is a rare etiological agent of chromoblastomycosis, with low rates of correspondence observed from reports. The main active components of F. compacta are glycolipids, yet very little is known about its composition. F. compacta is widely regarded as a dysplastic variety of Fonsecaea pedrosoi, its morphological precursor. The genus Fonsecaea presently contains two species, F. pedrosoi and F. compacta. Over 100 strains of F. pedrosoi have been isolated but only two of F. compacta.
Nannizziopsis guarroi was first documented in 2006 on a variety of lizards then described in Spain in 2010 and was classified as Chrysosporium guarroi, a member of the anamorphic genus Chrysosporium in the family Onygenaceae. Etymologically, the species epithet "guarroi" honours Professor Josep Guarro in recognition of his extensive mycological work including on the genus Chrysosporium. Skin samples taken from pet green iguanas suffering from dermatomycosis were sent to a laboratory for analysis. Five species were isolated and morphologic studies identified the fungus causing the mycoses as a member of the anamorphic species of Chrysosporium. Further investigation of these species using a combination of morphological, cultural and molecular studies showed that they were not identical to any previously described species within the genus Chrysosporium so they were classified as a new species Chrysosporium guarroisp. nov. The delineation of species in the genus Chrysosporium and their assignment to higher taxonomic levels can be challenging due to the marked morphological simplicity of these fungi. Increased scrutiny of strains of these fungi using molecular genetic tools has revealed numerous hidden species and unexpected relationships.
Candida tropicalis is a species of yeast in the genus Candida. It is a common pathogen in neutropenic hosts, in whom it may spread through the bloodstream to peripheral organs. For invasive disease, treatments include amphotericin B, echinocandins, or extended-spectrum triazole antifungals.
The Colubroides are a clade in the suborder Serpentes (snakes). It contains over 85% of all the extant species of snakes. The largest family is Colubridae, but it also includes at least six other families, at least four of which were once classified as "Colubridae" before molecular phylogenetics helped us understand their relationships. It has been found to be monophyletic.
