---|---|---|---|---|---|---|---|---|---|---|
A | B | C | D | F | G | H | I | K | Combb | |
Erythema migrans lesions (46) | 13 | 6 | 2 | 0 | 0 | 1 | 0 | 4 | 16 | 4 |
Ixodes scapularis ticks (74) | 12 | 12 | 11 | 9 | 6 | 5 | 7 | 1 | 5 | 6 |
The numbers of observations for lesions and for ticks were significantly different (χ2 = 36.3 with 9 degrees of freedom; P < 0.001).
Combined major groups (Comb) are defined by individual frequencies of 0.025 or less and include groups E, J, N, and O.
