Ringworm
built 263 days ago
Ringworm is most common in horses in Australia in periods of high relative humidity between November and April (summer). Clinical signs generally appear between 5-10 days following contact, and the hair within lesions becomes erect, and lesions become visible from a distance. The hair is easily plucked from the horse, occasionally in tufts where the hair is matted at the base by exudate to leave a grey, moist, glistening lesion. Single lesions may spread to about 35mm diameter. Hair regrowth generally starts about 30 days after infection. Itching is uncommon in horses.

Ringworm is an infection caused by a fungus that grows in the dead, superficial layers of the skin, hair or nails. It has nothing to do with worms. The scientific name for ringworm is dermatophytosis, and fungi which cause the disease are called dermatophytes. There are approximately 40 different species of dermatophyte, each tending to cause infection in particular species of hosts. In the cat, the cause of more than 90 per cent of cases of ringworm is the dermatophyte Microsporum canis (M canis). This organism can ... cause infection in many other species, including dogs and humans.

Ringworm is mildly contagious until the lesions start to get smaller. You can catch ringworm from other people as well as from domestic animals, most commonly cats and dogs. Some people are more vulnerable to getting the infection, for example people with eczema. In some instances, a person may even be genetically predisposed to the infection, causing repeat infections during their lifetime. Unlike many other infections, getting ringworm once does not give you immunity to it in the future. It is entirely possible to have repeat infections.

The skin lesions that appear with Ringworm are variable, and do not necessarily form a ring. There will be hair loss, usually in small patches at first. as time goes on the patches may disappear or appear at other locations on the skin. There might be scratching due to itchiness. If the hair loss occurs on the face or feet there is a chance it is due to digging habits or exposure to rodents.

Ringworm is characterized by patches of rough, reddened skin. Raised eruptions usually form the circular pattern that gives the condition its name. As lesions grow, the centers start to heal. The inflamed borders expand and spread the infection. Ringworm may ... be referred to as dermatophyte infection. It is more common in males than females, and is most common among children ages three to nine years.

Ringworm is spread by direct contact with a person or animal infected with the fungus. It can ... be spread indirectly through contact with articles (such as combs or clothing) or surfaces which have been contaminated with the fungus. A child with ringworm is infectious as long as the fungus remains present in the skin lesion. The fungus is no longer present when the lesion starts to shrink.
