Fungal infections of the skin are among the most common diseases in humans and animals. Microsporia and trichophytosis, conventionally united by the concept of "ringworm", often occur in humans upon contact with sick animals (cats and dogs). In Russia, up to 200 thousand primary patients are registered annually.

In recent years, with an increase in the number of homeless people and pets in cities, the incidence of ringworm has been rising. The number of affected domestic animals varies seasonally - the largest number occurs in the summer-autumn period. Infection occurs by contact from infected stray animals, when walking dogs together, from bedding and feeders.

With trichophytosis in animals, the hair, claws, and skin are affected. The clinical forms of the lesion are very diverse. This is due to the severity of the course of the disease, the degree of its spread and the duration of the disease. Often there are chronic, atypical, erased, difficult to detect symptoms of the disease, which last for months.

In the development of the disease in animals and humans, there are common features. All kinds of minor injuries, deposits of organic substances on the skin, an abundance of dandruff and dirt favor the development of fungal diseases. The disease in animals, like in humans, begins with redness of the skin, it becomes uneven, rough, bubbles appear, then crusts, abundant peeling is observed. Hair becomes dull, whitish-grayish, sometimes in bundles in different directions come out of the crust. In the future, they break off and fall off along with the crusts. In this regard, foci of baldness and flaking are formed. In some cases, papulovesicular rashes can be observed along the periphery.

Itching of lesions, especially on hairless parts of the body, is quite common with dermatomycosis in animals. Lesions of the claws are focal or diffuse in the form of foci of opacity, deformation and crumbly peeling in different parts of the claw, especially on the front limbs. In dogs, foci of trichophytosis are most often located on the scalp, limbs, and neck. More often dogs of short-haired breeds are ill. Trichophytosis is less common in cats. Without treatment, the disease lasts for quite a long time, many weeks and months, being a source of infection for others.

And microsporia is more common in cats. According to the clinical manifestations of microsporia and trichophytosis in animals, it has many common features, but the pathogen of microsporia differs significantly from the causative agent of trichophytosis.

Microsporia in cats is very diverse in its manifestations. Acute, vivid forms of the disease are characterized by foci of baldness of different sizes, at first small single, then multiple, and later merging, widespread. The lesions are covered with scales, less often with crusts, the skin on them is swollen, slightly swollen, bluish-pinkish, the hair is broken off.

The favorite localization of microsporia in cats is the scalp, nose bridge, near the ears and eyes, on the lower lip, neck, on the forelegs and at the base of the tail. Often, no noticeable lesions can be detected. Only by feeling small nodules and crusts are found. Very single vellus hairs on the inner surface of the auricles, eyebrows, eyelashes and mustache hair are affected. Foci of microsporia and individual affected hairs give a specific glow when exposed to ultraviolet light. Molting in cats promotes the rejection of hair affected by fungi, which leads to infection of premises, objects and things, litter and earth of everything with which the sick animal comes into contact.

Sick animals are difficult to treat and have been destroyed before (as a source of infection for people around them). The main method for the prevention and treatment of animal mycoses is their vaccination. Vaccines against dermatomycosis are one of a kind, which not only prevent the disease, but also cure it! You don't need to treat your four-legged pets without consulting a specialist - you can harm!

If you suspect ringworm, an urgent need to consult a mycologist and disinfect the room where the animals are usually located.
