Table 2. Abundance of the four tick species that were most highly submitted from humans and animals in the passive surveillance program in Québec, from 2007 to 2015: Number of I. cookei, D. variabilis, A. americanum and R. sanguineus.

Results are shown by the development stage as well as by single or multiple tick submission (i.e. more than one tick collected from the same person or animal at the same time).
