“…The dermal cellular immune response to S. scabiei infection has been examined in humans and animals including rabbits, dogs, foxes, chamois, and pigs (Sheahan, 1975;Ackerman, 1985;Van Neste, 1986;Morsy and Gaafar, 1989;Arlian et al, 1994Arlian et al, , 1996aArlian et al, , 1997Arlian, 1996;Little et al, 1998;Rode et al, 1998). Whilst marsupials have an immune system similar to that of eutherian mammals (Croix et al, 1989) differences have been identified such as slower antibody responses in some metatherians including wombats (Johnson et al, 1989;Wilkinson et al, 1992;Skerratt et al, 1997), suggesting that differences may exist in the immune response of wombats to S. scabiei that affect its ability to regulate the abundance of mites. In this study, conventional staining methods as well as immunohistochemistry using antibodies raised against conserved antigens were used to identify cell types in the dermis of common wombats infected with S. scabiei.…”
