Abstract
A total of 150 hair and skin scraping samples were collected from clinically suspected ring worm lesions found on different parts of the body of individually owned animals including; cattle (50), buffaloes (25), sheep (50) and horses (25) of different ages and sex from Abo El Matameer District, Behera Province during the period extended from June 2014 to May 2015 to be investigated for presence of dermatophytes. In addition, 50 samples of hair and skin scrapings were collected from human patients clinically diagnosed as having tinea of various ages and sex whom their history revealed that there was an animal contact with the examined species to be investigated for presence of dermatophytosis infection. Another 100 hair and skin scraping samples were collected from clinically suspected mange lesions found on different parts of the body of individually owned animals including; cattle (25), buffaloes (25), sheep (25) and horses (25) of different ages and sex from the same locality and during the same period of time to be investigated for presence of mites infestation. Samples were transported under possible aseptic condition with the minimum of delay to the laboratory of the Department of Animal Hygiene and Zoonoses, Faculty of Veterinary Medicine, Alexandria University where they were subjected to laboratory examination. The obtained results in the current study revealed that: The overall prevalence of dermatophytosis in examined hair and skin scrapping samples of different animal species was 74 % and the highest prevalence was observed in examined samples of sheep (78%) followed by buffaloes (76%) then cattle and horses (72 and 68%, respectively) and the statistical analysis showed non-significant association between the prevalence of dermatophytosis in the examined animal species.The statistical analysis showed non-significant association between the prevalence of dermatophytosis in males and females so sex has no effect on the prevalence of dermatophytosis in the examined animal species in the current study although the prevalence of dermatophytosis was higher in males than in females in examined samples of cattle (84.61and 67.57%, respectively) and horses (87.57 and 54.55%, respectively) while it was higher in females than in males in examined samples of buffaloes (78.95 and 66.67%, respectively) and sheep (79.49 and 72.73%, respectively).The statistical analysis showed non-significant association between the prevalence of dermatophytosis in different age groups under investigation although the prevalence of dermatophytosis was nearly equal in the two age groups of cattle (72.41and 71.34%, respectively) and it was higher in the age group (≥ 2 years) than in the age group (˂ 2 years) in buffaloes (80 and 73.33 %, respectively) and horses (70.59 and 62.5%, respectively). On contrary, it was higher in the age group (˂ 2 years) than in the age group (≥ 2 years) in sheep (92 and 64%, respectively) so age groups has no effect on the prevalence of dermatophytosis in the examined animal species.The frequency of isolation of dermatophytes revealed that: o T. verrucosum was isolated at the rate of 66.67, 57.89, 82.05 and 23.53% from cattle, buffaloes, sheep and horses, respectively. oT. mentagrophtes was isolated at the rate of 25, 42.11, 5.13 and 11.76% from cattle, buffaloes, sheep and horses, respectively. oM. canis was isolated at the rate of 8.33 and 12.82 % from cattle and sheep, respectively while it was not be isolated from buffaloes and horses.o T. equinum was isolated from the examined samples of horses only (64.71%).The statistical analysis showed significant association (94.47, P<0.0001) between the frequency of isolation of dermatophytes from investigated animal species and the overall rate of isolation of T. verrucosum was the highest (63.96%) followed by T. mentagrophytes (18.92%) then T. equinum (9.91%) and finally M. canis (7. 21%).The overall prevalence of dermatophytosis in examined samples of the clinically suspected human patients was 82%.The statistical analysis showed non-significant association (1.1066 NS) between the prevalence of dermatophytosis in males and females so sex has no effect on the prevalence of dermatophytosis in the human patients in the current study although the prevalence of dermatophytosis was higher in males (86.67%) than in females (75%). The statistical analysis showed non-significant association between the prevalence of dermatophytosis in different age groups so age has no effect on the prevalence of dermatophytosis in the human patients in the current study although the prevalence of dermatophytosis was higher in the age group (15 - ˂ 30 years, 85.16%) followed by the age group (˂ 15 years, 84.62 %) and the age group (≥ 30 years, 70%) The statistical analysis showed non-significant association between the prevalence of dermatophytosis and the clinical types of tinea although it was noticed that T. corporis constituted the highest prevalence (86.96%) followed by T. capitis (81.82%) then T. pedis (80 %) and finally T. cruris (66.67%). •The statistical analysis showed non-significant association between the frequencies of isolation of dermatophytes from clinically suspected human patients and the overall rate of isolation of E. flocosum was the highest (39.02%) followed by T. verrucosum (34.15%), M. canis (17.07%) and finally T. mentagrophytes and T. violoaceum (14.63% of each).The statistical analysis showed significant association (11.11, P<0.05) between prevalence of mange in investigated animal species in the current study. The highest prevalence was observed in sheep (72%) followed by cattle (48%) then buffaloes (36%) and finally horses (28%).The statistical analysis of the obtained results showed non-significant association between the prevalence of mange in females and males so sex has no effect on the prevalence of mange in the examined animal species in the current study although the prevalence of mange was higher in females than in males in examined samples of cattle (50 and 44.44%, respectively), buffaloes (38.89 and 28.57%, respectively), sheep (84.62 and 58.33%, respectively) and horses (28.57 and 27.27%, respectively). .The statistical analysis showed significant association between the prevalence of mange in different age groups under investigation. The prevalence of mange was higher in the age group (≥ 2 years) than in the age group (˂ 2 years) in cattle (87.50 and 29.41%, respectively), buffaloes (50 and 26.67%, respectively) and horses (28.57 and 27.27%, respectively). On contrary, it was higher in the age group (˂ 2 years) than in the age group (≥ 2 years) in sheep (72.72 and 71.43%, respectively).• The statistical analysis showed non-significant association between frequencies of isolation of mites from investigated animal species. It was found that the overall prevalence of Sarcoptes spp. and Psoroptes spp. was 56.52 and 43.48%, respectively.Concerning cattle, it was found that the prevalence of Sarcoptes spp. (58.33%) was higher than Psoroptes spp. (41.67%). In buffaloes, the prevalence of Sarcoptes spp. (66.67%) was higher than Psoroptes spp. (33.33%). Moreover, the prevalence of Sarcoptes spp. (71.43%) was higher than Psoroptes spp. (28.57%) in horses. On contrary, it was found that the prevalence of Psoroptes spp. (61.11%) was higher than Sarcoptes spp. (38.89 %) in the examined samples of sheep.
