Nannizziopsis guarroi causes a skin infection mostly in reptiles which can progress to the subcutaneous layers and deeper tissues resulting in the death if not quickly identified and treated. Treatment options usually involves the application of topical agents such as ketoconazole, itraconazole or terbinafine combined with the removal of ...
As in other reptiles, the skin of lizards is covered in overlapping scales made of keratin. This provides protection from the environment and reduces water loss through evaporation. This adaptation enables lizards to thrive in some of the driest deserts on earth. The skin is tough and leathery, and is shed (sloughed) as the animal grows.
Leishmania / l iː ʃ ˈ m eɪ n i ə,-ˈ m æ n-/ [1] is a parasitic protozoan, a single-celled organism of the genus Leishmania that is responsible for the disease leishmaniasis. [2] [3] [4] They are spread by sandflies of the genus Phlebotomus in the Old World, and of the genus Lutzomyia in the New World.
However, it is represented by only one living species: the tuatara (Sphenodon punctatus), a superficially lizard-like reptile native to New Zealand. [ 5 ] [ 6 ] Lepidosauria is a monophyletic group (i.e. a clade ), containing all descendants of the last common ancestor of squamates and rhynchocephalians. [ 7 ]
A study conducted in 2014 established the existence of endogenous circadian rhythm in pigmentation changes in P. vitticeps; if exposed to sun, the dorsal skin of the lizard becomes darker, and if exposed to darkness, it becomes lighter. Under constant darkness (i.e. in the subjective night), the lizard's dorsal skin becomes the lightest. [7]
The body temperature of the lizard during hibernation is 15.0 to 30.5 °C, but in many areas, the average body temperature during hibernation is around 16-18 °C. [ 5 ] The species is one of the few monitor lizards that tolerate relatively cold temperatures, being present as far north as south-west Kazakhstan.
This was the standard treatment until 1997, when a taxonomic review based on color and morphology indicated that the ornate monitor is distinctive and revalidated it as a separate species from rainforests of West and Central Africa. [13] In 2016, a review based primarily on genetics came to another result.
The Asian water monitor is one of the most exploited varanids; its skin is used for fashion accessories such as shoes, belts and handbags which are shipped globally, with as many as 1.5 million skins traded annually [1] and between 50,000 and 120,000 skins harvested from the wild in peninsular Malaysia.
