Abstract

Abstract: This study supports the airborne dissemination of Clostridioides difficile spores. 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.
