Of the sieve impaction samples collected at a swine production unit, 66.7% were positive and all belonged to the predominantly established clone. Spores' density varied according to the characteristics of the animal population, suggesting the possibility of airborne transmission.Highlights: Overall, 66.7% (4/6) of the impaction air samples were positive for C. difficile; All air samples from the farrowing and weaning piglets' units were positive; All C. difficile positive samples belonged to the same toxigenic RT033 clone; Bacterial spores count correlate with animal colonization rate; Aerial dispersion might contribute for the environmental spread of C. difficile.engClostridium dificileAir DisseminationInfecções GastrointestinaisAvaliação do Riscojournal article10.1016/j.anaerobe.2022.102651
