[Histopathologic changes of bird skin in feeding places of ticks of the genus Ixodes (Acari: Ixodidae)].

Histopathological changes of skin of Passeriformes birds in the places of attachment and feeding of the Ixodes persulcatus and I. lividus were investigated. The inflammation of bird skin is analogous to one of mammalian skin. The mouthparts of tick are surrounded by the fibrin cone and collagen capsula. They are formed by host. Ticks of these species do not form the cement. A proliferation stage of skin inflammation in birds is expressed. The thick collagen capsula develops in a result of proliferation. The feeding cavity is formed by the process of sucking a blood, inflammate cell infiltrate and products of tissue lysis. Neutrophils and eosinophils predominate in the inflammate cell infiltrate.
