phenotypic and genotypic characterization of spotted fever group rickettsiae isolated from catalan rhipicephalus sanguineus ticks.eighty-nine rhipicephalus sanguineus ticks and 21 rhipicephalus bursa ticks collected in catalonia were tested by the hemolymph test to establish their infection rate with spotted fever group rickettsiae. by giménez staining, 11.2% of the r. sanguineus isolates and 0% of the r. bursa isolates were found to contain rickettsia-like organisms. six spotted fever group rickettsial strains (bar29, bar31, gir4, tar1, tar2, and tar3) were isolated from these ticks and were characterized by phenotypic an ...19968897166
