الملخص EN

Ringworm is an infectious disease of animals caused by different species of dermatophytes.

It is a major public and veterinary health problem reported in the different parts of the world including Egypt and causes great economic loss, through body weight loss, skin injuries, and long course of treatment.

This study was carried out on 230 cattle infected with skin lesions from a total number of 1350 animals, in different ages, sex, breeds and in different seasons and localities at Assiut Governorate.

These animals were subjected to clinical and laboratory examinations and the infected animals were subjected for treatment with different antifungal agents as (Mycostatin ointment, Trocid Lotion, Tinct-ure iodine, Garlic Juice, Mange-cide ointment.).

The obtained results indicated that animals housed in close proximity to each other for long periods in the fattening period in the presence of infected one lead to spreading spores of fungus between animals and so a greater infection rate was recorded in males compared with females.

Also, the result reported a higher infection rate in winter than summer season.

The percentage clinically diagnosed cattle with ringworm was 17 % at Assiut Governorate with higher frequency of isolated Trichophyton verrucosum (98 %) from the examined animals infected with ringworm (98 %).

The most effective and cheap drug used for treatment of infected animals was Tincture iodine in concentration of 5 to 7 % which used as paint or spray with 100 % recovery rate.
