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.
