Epidemiological studies of Egyptian buffaloes mange with special reference to efficacy of different therapeutic trials for treatment of mange

ABSTRACT

The present study was conducted on 280 Egyptian buffaloes [Bithalis bubalus] during the period from June 2008 to July 2009. These animals belong to different villages in Assiut Governorate, Upper Egypt. The age of these animals ranged from less than one year to above eight years old. Examination of diseased animals revealed that they suffered from itching, loss of patches of hair in different regions of the body with appearance of scales on the skin. The more common sites of infestation were the head, neck and the base of the tall. In this study skin scrapings were examined microscopically revealed that Sarcoptic spp. and psoroptic spp. were identified from Egyptian buffaloes in Upper Egypt in percentage of 11.78%and 8.57%, respectively, with overall percentage of 20.35%. infestation by Sarcoptic mange mites [57.89%] was recorded to be the most frequent in the examined cases, followed by Psoroptes spp. mites [42.10%]. Statistical analysis of some ecological parameters reveled that there is a significant relationship between prevalence of mange mite Infesting buffaloes and season, age, housing management as well as regular or irregular using acaricides. Moreover, this study included using different methods of clinical therapeutic trails. The infested buffaloes with mange mites were classified into four groups. The first one received two doses of Ivermectin [Ivomec, Merial], 10 days apart at dose rate of 200 micro g/kg subcutaneously. The second group received two doses of doramectin [Dectomax, Pfizer, Egypt] a, 10 days apart at dose rate of 200 micro/kg subcutaneously. The third group received two doses of Ivermectin [Ivomec, Merial], 10 days apart at dose rate of 200 micro g/kg subcutaneously, Adjunct to this drug, Deltamethrin [Butox-50, Intervet] was applied to the surrounding environment [bedding material, wall, fomites, etc....] twice at a 10 days interval, All cases were isolated in a separate place during treatment period. The fourth group received two doses of doramectin [Dectomax, Pfizer, Egypt] a, 10 days apart at dose rate of 200 micro g/kg subcutaneously, Adjunct to this drug, Deltamethrin [Butox-50, Intervet] was applied to the surrounding environment twice at a 10 days interval. We found that administration of Ivermectin or doramectin adjunct with treatment of animal environment Is the best protocol for eradication and prevention of mange mite from Infested buffaloes with mange mite and Its environment
