Seroprevalence of zoonoses in a Cree community (Canada)
Cree trappers and hunters are at risk for contracting infectious diseases conveyed by wildlife. We performed a study in a Cree community (Canada) to determine the seroprevalence of 8 zoonotic infections among hunters and trappers for evidence of exposure to Trichinella sp., Toxoplasma gondii, Toxocara canis, Echinococcus granulosus, Leptospira sp., Coxiella burnetii, Francisella tularensis, and Sin Nombre virus. A total of 50 participants (28 women and 22 men) were included in this study. Results indicate no or infrequent exposure to the Sin Nombre virus (0%) and 3 of the 4 parasites investigated (0-4%). Exposure to T. gondii (10%) and some bacteria appeared to be more prevalent (range, 4-18%). Overall, seropositivity was related to fishing, hunting, and trapping activities. Physicians should be aware of these infections in this population, particularly Q fever, tularemia, and leptospirosis.
