[Ixodes ticks of the town of Cherkessk and its environs]

The paper presents the results of the studies made in 2002-2004 to examine the species-specific composition of Ixodes ticks. The ticks were gathered for a flag (155km routes being covered and 405 ticks being gathered); 48 dogs were examined, 320 ticks being gathered; 212 ticks were collected from human beings. The town dwellers' visit rates were grouped by ages and months. In the republic, Borreliae, the causative agents of Lyme borreliosis, were first isolated from Ixodes ricinus by darkground microscopy. Thus, there is one more available Lyme borreliosis focus. Enzyme immunoassay was used to study the sera from the dwellers bitten by ticks. Anti-M and anti-G antibodies were isolated. The paper presents the distribution of Ixodes ticks gathered for the flag and taken from dogs in accordance with the biotopes, establishes seasonal variations, and provides calculations of the abundance index on the dogs.
