They were diagnosed phenotypically in the laboratories .  ticks were recorded: Hyalomma  with three species belonging to Hyalomma: H. anatolicum, H. truncatum, H. excavatum .Ticks are comparatively big acarines, which are vertebrate ectoparasites that feed on blood.Crusts and scabs were often the most common gross pathologic lesions, and they primarily resulted from traumatization or degeneration following previous primary lesions.In the current investigation, some clinical symptoms like overall weakness, skin redness, and the observation of some scratches in the tick attachment sites were observed during the visual inspection of infested animals. Both sides of the epidermis are inflammatory and more, particularly the lymphocytes, mononuclear cells, and eosinophil cells.
