a
P = 0.014 (when compared to the number of p44 species expressed in the blood).
b
P = 0.014 (when compared to the number of p44 species expressed in the midgut).
c
The Westchester tick was one naturally infected tick collected in Westchester County, N.Y. The NTN-1 ticks identification included five ticks experimentally infected with the NTN-1 strain of A. phagocytophilum.
