Abstract

This study was carried out on 200 Ringworm infected camels’ samples under release breeding system in two governorates; Homs and Deir- eizour (Syria) during the period of March, 2010 till February, 2011 aiming for isolating and determining the dermatophytes that cause ringworm in camels. Samples were collected from clinically infected animals untreated by medicine, of which 100 samples from old camels aged (3-10 years), and 100 samples from small camels aged to 3 years. Laboratory tests were carried out by dividing each sample into two parts, the first part for direct microscopic test using Potassium Hydroxide solution 20% (KOH), and the second part for fungal planting on alimentary matrix Sabouraud,s Dextrose Agar (SDA). The morphological and colonial characteristic of outgrowth fungal colonies by microscopic and ocular exams were used to determine the gender and sort of fungous pathogenic. Results showed for the first time in Syria isolation and determining two sorts of fungous pathogenic which cause Ringworm in camels; the first was Trichophyton verracusum and the second was Trichophyton  mentagrophytes where the rates of isolation in the two governorates in old camels as an average of 77.5% and 13.75%  of isolations respectively, and it was appeared mixed isolation rate for two fungus which amounted 8.75%, whereas in small camels the rates of isolations amounted in averages of 94.5% and 5.49% respectively, but there was no significant difference between gender and sort of fungous pathogenic in the two governorates .The rate of samples that gave a positive result for ringworm infection by direct macroscopic test method with an existence of 20% KOH in old and small camels as an average of 92% and 95% of infected cases respectively. The rate of samples that gave growth of fugal colonies were 80% and 91% of positive cases of microscopic test respectively.

Abstract

This research was carried out on 1639 heads of camels in two Syrian governorates, Homs and Deir- Ezzour during the period of March 2010 till February 2011 to recognize prevalence of Ringworm infection under the conditions of breeding release. Clinical symptoms of infection were recorded i.e. age of infected animals, sex, and general condition. The infections were listed according to the seasons of the year. The clinical symptoms appeared in the form of lesions and distinctive circular spots covered with dry dense white scurf, localized mainly in the head, neck, chest, front standings and sometimes in all over the body. Results showed sufficient difference (p<0.01) in the prevalence of infections among the ages of infected animals, where the infections were greater in small aged camels till three years old where the ratio was (31.87%), while it was (9.58%) in camels their ages within the range (3-10) years. Infection prevailed in both sexes, male and female, where the ratio of infection was greater in old female camels (10.05%) comparing to old males (6.01%), also it was greater in small females (35.4%) comparing to male animals (27.63%), but there is no significant difference between the two sexes. The ratio of prevalence infections varied according to the seasons of the year with significant difference (p<0.001). It was for old camels in winter, autumn, summer and spring (14.63%،, 10.95%،, 7.69%, 4.98%) respectively. While the ratio in small camels with significant difference (p<0.05) (40.94%, 33.60%, 29.26%, 23.84%) respectively. These results is considered important for charged people in the veterinary and health sectors, because it helps them in setting protective schedules programs that can reduce the ratio of prevalence the infection in animal.
