molecular identification of rickettsia parkeri infecting amblyomma triste ticks in an area of argentina where cases of rickettsiosis were diagnosed.	specimens of the hard tick amblyomma triste were found infected with rickettsia parkeri in an area of argentina (general lavalle, buenos aires province) where cases of human illness attributed to this microorganism have been reported. molecular detection of r. parkeri was based on polymerase chain reactions that amplify a ca. 400-bp fragment of the 23s-5s intergenic spacer and a ca. 500-bp fragment of the gene encoding a 190-kda outer membrane protein. three (6.97%) of 43 a. triste ticks were de ...	0	23440128
