摘要: Genetic traits of five Rickettsia prowazekii isolates, including the first from Africa and North America, representatives human flying squirrels were compared using multilocus sequence typing. Four rickettsial genes encoding 17 kDa genus-common antigen (17 kDa gene), citrate synthase (gltA), OmpB immunodominant (ompB) 120 kDa cytoplasmic (sca4) examined. Sequence identities gene gltA 100% among isolates. Limited diversity ompB (0.02–0.11%) sca4 (0.03–0.20%) was enough to distinguish evaluation combined four provided a method easily differentiate R. other rickettsiae.
