Ring Worm
Ringworm is an infection of the skin, hair or claws, caused buy a type of fungus. In dogs, about 70% of ringworm cases are caused by the fungus Microsporum canis, 20% by Microsporum gypseum, and 10% by Trichophyton mentagrophytes. The infecting fungus is spread easily in the environment. People can easily be infected with these fungi.
Most cases of ringworm are spread by contact with infected animals are contaminated objects such as furniture or grooming tools. Broken hairs with associated spores are important sources for spread of the disease. Contact does not always result in infection. Whether infection is established depends on the fungal species and on host factors, including age, health, condition of expose skin surfaces, grooming behavior and nutrition. Infection leads to short-lived resistance to reinfection. Under most circumstances dermatophytes grow only in the in the dead cells of skin and hair, and infection stops on reaching living cells or inflamed tissue. As inflammation and host immunity develop, further spread of infection stops but this process may take several weeks.
Infected dogs develop bald, scaly patches with broken hairs in ring-like whirls. Re most common sites affected by ringworm are the face, ear tips, tail and feet. Ringworm is diagnosed by fungal culture examination with anultraviolet lamp, and direct microscopic examination of hair or skin scale. Fungal culture of hairs and scrapings from the affected areas is the most accurate method. Direct microscopic examination of hairs or skin scrapings may allow early diagnosis.
Ringworm infections usually clear up without treatment but medicated shampoos might speed recovery in some cases. Such treatments are not always affective, however.
