[Histopathological changes in the skin of the rabbit fed on by preimaginal phases of the tick, Alveonasus lahorensis (Argasidae)].
During the feeding of larvae and nymphs of A. lahorensis haemorrhagic inflammation develops in the rabbit's skin. Lymphocytes and macrophages are the dominant cell elements in the reaction while during the feeding of nymphs eosinophilous leucocytes are observed in great number in the infiltrate. Around the oral parts of the tick an infiltration of collagenous fibres of the connective tissue is formed, which serves for a more firm attachment of the parasite, while beneath the proboscis a light band is formed from which the tick sucks the food substratum. By the end of the feeding of nymphs III in the place of skin affection a crust can be formed on account of the host's atrophied tissues, and in the integuments there are formed necrotic foci due to the hystolitic and toxic effect of the saliva.
