Abstract: Chorioptes mange is a skin disease affects both domestic and wild ruminants. A total of 341 Egyptian buffaloes, aged from 2 to 10 years old were examined clinically to determine incidence rate, clinical finding, age susceptibility of Chorioptic mange besides measuring cell mediated immune response of Chorioptic mite infested buffaloes. Incidence of Chorioptic mange was recorded in 252 out of 341 (73.9 %) Egyptian buffaloes raised in Alexandriacity, Egypt. With higher incidence at age group 6-9 years old. Microscopic examinations of skin scraping revealed chorioptic mite at all stages. Chorioptic mange infestation reduced the milk yield. Infested buffaloes with Chorioptic mange had lower lymphocyte transformation index which were 22.52±6.77 as compared with non-infested buffaloes 32.45 ± 4 .49. Chorioptes pruritus and injury in lower leg region found to be in concurrent with staphylococcal dermatitis and edematous skin disease infection. 252 infested buffaloes with Chorioptes, 92 and 71 of them suffered from Staphylococcal dermatitis and edematous skin diseases, respectively, 53 buffaloes showed both infections. 89 non-infested buffaloes with Chorioptes, 8 of them showed edematous skin disease and no staphylococcal dermatitis infection. This confirms our hypothesis that Chorioptic mite plays an important role in initiating staphylococcal dermatitis and edematous skin disease infection.
