In a previous study conducted in Cyprus, various spotted fever group Rickettsia species were detected and identified in ticks by molecular analysis. Among them, a partially characterized Rickettsia species was detected in Hyalomma anatolicum excavatum and Rhipicephalus turanicus ticks. We report characterization of this rickettsial strain by using polymerase chain reaction sequencing analysis of partial citrate synthase A, outer membrane protein A, outer membrane protein B, and 17-kD protein genes. We propose a provisional name Rickettsia sp. strain Tselenti for this strain until it is isolated and further characterized.
