Mikrosporia-fungus disease skin and hair

Before mikrosporia was called ringworm. Exciter mikrosporia was first described in the mid-19th century it was discovered on the surface of infected by fungus hair skin that consists of small, mosaic spread spores. Later were found and other types of fungi that cause mikrosporia.

What is and how it can be mikrosporia fall ill

Mikrosporia-dangerous fungal infection caused by fungi – dermatofilami kind Microsporium. There are three groups of agents belonging to this genus:

antropofil′nye-they may cause only in people;

zoofil′nye – cause disease in cats and dogs, which can become infected people;

geofil′nye-they live in the soil and sometimes (very rarely) can cause mikrosporiû in humans and in animals.

In addition, in the event of disease are important factors such as reduced defenses (immune system), caused by improper diet, lack of vitamins, various chronic diseases. Infectious easier to penetrate the skin when its integrity for injuries, bruises, abrasions are bacterial inflammation of the skin, caused by a violation of the rules of hygiene.

Antropofil′nym types of fungus are highly contagious, they are able to cause massive infections in children’s collectives, families in using the common linen, clothing and toys. Individuals of this species of fungi are common in many Western European countries and in the United States. Other members of the antropofil′nym fungus more common to the East in Japan, China, and India. In our country there are both types of antropofil′nym fungi.

Infecting fungi species zoofil′nym people descended from cats, more rarely from dogs, therefore, of particular importance is that the homeless mikrosporia animals. There are also healthy animals mikrosporia carrier How do people get in direct contact with sick animals or objects contaminated with their hair. Get sick mostly children, but also adults quite often. Recovery rates noted in the autumn season. In our country most common mikrosporia views zoofil′nym.

Geofil′nye fungi are found in soil all over the world and occasionally cause mikrosporia in individuals whose work is connected with the ground. This form is not very contagious mikrosporia.

How is

At mikrosporia caused by zoofil′nym fungi, the incubation period (time from infection until the first moment of its manifestations) lasts from three to seven days, after which the skin, on the spot of mildew appear rosy, systemic and oval shape of rounded spots usually expressed without inflammation, with clear boundaries and desquamation on the surface of otrubevidnym. With the defeat of downy hair on the smooth skin. The impact of the scalp there are one or more large round pockets, hair that breaks at 5-8 mm above the skin and covered with white dust cover of the pathogen spores. Around the main foci are smaller pockets. When hair loss is also possible mikrosporyi beards, moustaches, eyebrows, eyelashes, rarely-nails. When attaching the bacterial infection may cause suppurations and temperature.

At mikrosporia caused by antropofil′nym fungi, the incubation period can last up to 4-6 weeks. Hot spots on the skin are kind of rings, inscribed one to another. When the scalp is the propensity of the merger and the formation of large tracts of defeat, increasingly localized around the edges. In the centers along with broken hairs lesion meet and healthy.


Diagnosis is made by very mikrosporia specific signs of the disease and is supported by laboratory tests-discovery on the hair smaller, mosaic spread spores, mycelium-skin Flake (branched filaments overlapping) fungus. To determine the type of fungus is the seeding of the affected hair or flakes of skin on the special environment in order to obtain culture fungi.

In addition, a luminescent method of diagnosis mikrosporia: affected hair the Luminescent lamps give green luminescence.
