Bait uptake and seroprotection rates in foxes and raccoon dogs from 2006 to 2010.

TC: tetracycline.CI: Confidence Interval.Ab positive sera: rabies antibody titer by ELISA≥0.5 EU/mL.Tetracycline, used as a biological marker, was sought in the lower jaw of the foxes and raccoon dogs killed in vaccinated zones. The number of positive samples out of the total samples and the positivity percentage for tetracycline are reported by target species (red fox and raccoon dog).Sera were analysed with an indirect ELISA kit (Platelia Rabies II kit, Biorad). A threshold seroconversion of 0.5 EU/mL was adopted.
