- Abstract: Ticks are important ectoparasites which transmit many disease pathogen to animals; these are labelled tick borne diseases (TBD). Tick induced damage to skin and hides has not received attention. Skin and hides are important for the leather product industry, particularly in Pakistan. Due to economic importance and financial loss by ticks in leather industry, the present study was designed to investigate skin and hides damage due to ticks at microscopic level. Naturally tick infested tissue samples of hides and skin were collected from slaughter houses. Primary lesions at tick feeding sites showed epidermal edema with adjacent dermal edema. Histopathological examination revealed degeneration of epidermal layer down to the basal layer. Epidermal and sub dermal layers often displayed focal necrosis infiltrated with neutrophils and mononuclear cells at tick bite sites. Hyperplasia of keratinocytes was also seen at sites of ruptured epidermis. Quality of leather depends upon the grain (Outer) surface skin/hides. Ticks infestation damages the outer surface, due to bites, inflammatory responses, and secondary bacterial infections that often become established at feeding sites. Control of ticks should be given consideration to reduce infestation induced losses in the leather industry in Pakistan.
