Abstract
Dermatophytosis is a skin disease of farm animals caused by different species of the Microsporum and Trichophyton genera. Although the disease is self-limiting, ringworm has a major public and veterinary health problem with worldwide distribution including Egypt with huge economic loss in form of reduce weight gain, damage of hide with long costive treatment course.
Therefore, the objectives of this study were to estimate the infection rate of dermatophytosis in ruminants, identify the incriminated dermatophyte species and to identify and differentiate the isolated dermatophytes from naturally infected cows, sheep and goats at species level using both conventional methods and restriction fragment length polymorphism (RFLP). Moreover, assessment of the role of risk factors in the occurrence of the disease was carried out. Moreover, assessment the efficacy of different topical and systemic preparations on cure the infection of dermatophytosis in infected animals.
This study was performed on 111 ruminants out of 370 ones during the period from June 2018 to July 2019 with different breed, sex and age with great concern to concurrent environmental factors were included. The examined animals were located in two provinces of Egypt (Sharkia and Dakhalia). These animals were subjected to clinical and laboratory examinations and molecular diagnosis by the use of restrication fragment length polymorphism (RFLP) with MVI restication enzymes. A clinical treatment trial is going on by using 30 animals of cow (15) and sheep (15) under observation for 10 weeks.
