About location of Rhipicephalus annulatus (Say, 1821) (Acari, Ixodidae) ticks in the Kyzylorda region and their epizootological significance

Abstract

Recently, there has been a change in the border of the ranges of ixodid ticks in the Kyzylorda region, respectively also the spread of various infections carried by them. The collected material on the fauna and distribution of ixodid ticks indicates an increase in the number of new species of ixodid ticks in this area. As a result of an epizootological survey of settlements in the southeastern part of the Kyzylorda region the Rhipicephalus annulatus ticks, carriers of pathogens of cattle pyroplamosis, were discovered for the first time in this region. As a result of an epizootological survey of settlements in the southeastern part of the Kyzylorda region in the fall of 2019 in two villages of the Zhanakorgan region, for the first time, several specimens of ticks were found on cattle, identified as Rhipicephalus annulatus - carriers of the pathogens of cattle pyroplamosis. In 2020, during repeated examinations of the same settlements, similar ticks were found at all stages of development. In the study by the method of enzyme-linked immunosorbent assay (ELISA) from ticks of this species, the antigen of the Crimea-Congo hemorrhagic fever virus was detected.
