Isolate source (n)No. of observations in isolates of major ospC groupa:
Erythema migrans lesions (118)231976973216
Disseminated infections (44)2140030160
  • a Numbers of isolates from lesions and from disseminated infections were significantly different (χ2 = 23.6 with 7 degrees of freedom; P < 0.005).

  • b Combined major groups (Comb) are defined by individual frequencies of 0.025 or less and include groups C, D, E, M, N, O, T, and U.
