Size Distribution and Pathogenic Potential of Culturable Airborne Clostridium spp. in a Suburb of Toyama City, Japan.

ABSTRACT: Clostridium spp. are anaerobic, Gram-positive, spore-forming bacteria comprising more than 150 species, some of which are important pathogens of humans and animals. Members of this genus have been isolated from a number of environments, but are rarely found in the atmosphere. In the present study, we exami-ned culturable airborne Clostridium spp. and clarified their pathogenicity. We obtained 19 culturable Clostridium isolates from size-fractionated samples collected at a suburban site in Toyama, central Japan. Culturable Clostridium spp. were detected in particles larger than 1.1‍ ‍μm, and the size distribution peaked at 2.1-3.3‍ ‍μm, corresponding to the spore size of Clostridium spp. More Clostridium spp. were detected in coarse particles >2.1‍ ‍μm not only by culture methods, but also
