  2. a Mean of positivity rate estimated on pen-based oral fluids and individual buccal swabs collected from 24 pigs divided in 4 groups [45]
  3. b Mean of positivity rate estimated on pen-based oral fluids and individual nasal swabs collected from 8 pigs divided in 3 groups [68]
  4. c Mean of positivity rate estimated on pen-based oral fluids and individual buccal swabs (frothy saliva) collected from 15 pigs, sampling 3 rolling 5-pigs groups [10]
