Description: chytrid fungi (mostly aquatic organisms) are a group of lower fungi of microscopic size and primitive organization, mostly unicellular and mononuclear, living parasitically, and sometimes saprophytic on various aquatic plants, especially on algae, as well as on small aquatic animals.
Amphibian chytridiomycosis is an infectious disease (caused by Batrachochytrium dendrobatidis) that affects the skin of adult amphibians and the oral cavity of their larvae. The disease was discovered quite recently. Its distribution area covers Australia, North and Central America and the Caribbean region. It spreads at a speed of 100 km / y.
In nature, it causes epidemics, as a result of which, whole colonies of amphibians die out. Most likely, B. dendrobatidis can infect not only aquatic but also terrestrial amphibians. When dried, zoospores and zoosporangia die. Not dangerous to humans, since it does not reproduce at temperatures above 31 ° C.
Reasons: not known. Presumably, infection occurs at the time of contact of the skin of the amphibian with contaminated water.

Symptoms: In young and adult amphibians, include neurological symptoms (abnormal posture), thickening of the epidermis (barely visible roughness of the skin surface), half-closed eyes, anorexia, lethargy, pale skin, beak deformities in tadpoles, sudden death.
Diagnostics: examinations of skin taken from the extremities. Basic examinations (histology, culture) are insensitive.
Treatment: Treatment with Fluconazole and Itraconazole may lead to recovery in some cases.
A 1% suspension of Itraconazole is diluted with 0.6% saline to a final concentration of Itraconazole of 0.01%. The amphibian is placed in the solution for 5 minutes a day, the treatment is carried out for 10-11 days.
Additionally, the animals are given ultraviolet baths.
Prevention: not known.

What is the use of them? Who might like them? In everyday life, you can often hear how many express their unflattering attitude towards amphibians. Some despise them, others disdain or, others are indifferent to them. Among the people, amphibians have never enjoyed love
Many owners of frogs, toads, salamanders and other amphibians have little simple communication with them. We give them names out of habit, like cats and dogs. But for the latter, thousands of nicknames have already been invented, but for "slimy and cold" there are no such lists … Therefore, you usually have to smash your head over how to name the pet. M
Anyone who has ever kept newts or salamanders knows that a variety of worms are used as food . In this article, we'll show you what types of worms are commonly used for feeding, how to make them more nutritious, and whether you can grow them at home
Amphibians, or amphibians, are the first terrestrial vertebrates that still retain significant connections with the aquatic environment. In most species, eggs (eggs) are devoid of dense membranes and can only develop in water. Each egg is surrounded by a transparent mucous membrane that swells in water
Despite the large number of species - about 2100, the general appearance and structure of tailless amphibians are of the same type : the neck is not expressed, the wide head imperceptibly passes into a short, slightly flattened body; adults have no tail; the hind limbs are 2-3 times longer than the front ones, have an additional section - the tarsus
