Epidemiology and Hematobiochemical Changes in Egyptian Buffaloes Infested by Psoroptic Mange

摘要

Background and Objective: Psoroptic mange is a serious contagious skin disease causes economic losses in buffaloes. The present study was carried out in naturally mange infected buffaloes (308) from different localities of Menofia province, Egypt to determine the prevalence, hemato biochemical parameters , risk factors associated with mange and describe the morphology of causative mite. Materials and Methods: Three hundred and eight buffaloes were physically inspected for mange lesions and signs. Microscopic examination of 33 clinically infested buffaloes was performed. Different hematological and biochemical parameters were evaluated in infested and non infested buffaloes. The morphological description and measurements of recovered Psoroptes were recorded. Results: Clinical examinations revealed that 53.90% (166/308) of examined buffaloes were infected with mange. The highest infestation rate was recorded in spring season in all ages with highly significance in buffaloes of more than 5 years of age. The infestation rate of mange was higher in females than males. Back was the most affected part with an infestation rate of 58.43 while the ear was the lowest affected part (1.81%). Microscopic examinations indicated that 100% were Psoroptes spp. There were significant decrease in packed cell volume, hemoglobin, total protein, albumin and globulin in highly infested buffaloes. Conclusion: The age, sex and season had significant effect on the prevalence of psoroptic mange in Egyptian buffaloes at Menofia Governorate, Egypt with significant decrease in hematological and biochemical parameters in highly infested buffaloes.
