Spotted fever group (SFG) rickettsiae were identified by indirect immunofluorescent antibody tests in 1.1% of 6,956 specimens of Dermacentor variabilis collected on Cape Cod, Massachusetts. Forty-one of 45 rickettsial isolates were serotyped as Rickettsia montana, one as Rickettsia rickettsii, and three were unidentified. Studies of canines and humans with clinical evidence of spotted fever, and of healthy dogs with antibody to SFG rickettsiae, indicated that exposure of the canine population to R. montana was common but that R. montana was not involved in the etiology of spotted fever.
在马萨诸塞州科德角采集的6956份变异革蜱样本中，通过间接免疫荧光抗体试验在1.1%的样本中检测到斑点热群（SFG）立克次体。45株立克次体分离株中，41株血清型鉴定为蒙大拿立克次体，1株为立氏立克次体，3株未鉴定。对有斑点热临床证据的犬类和人类，以及对SFG立克次体有抗体的健康犬类进行的研究表明，犬类群体接触蒙大拿立克次体很常见，但蒙大拿立克次体不参与斑点热的病因。
