Aiborne microorganisms were isolated with a sampler in two types of swine confinement buildings (farrowing units and fattening units).
Respirable (particles<5 mum) and total dust fractions were obtained.
The predominant microorganisms isolated were bacteria with an important fraction in the respirable size.
Only small quantities of gramnegative bacteria, yeasts, and molds were found.
Identification of the colonies isolated revealed a great diversity of microorganisms present in the air of the different buildings.
Enterobacter agglomerans, Moraxella, Acinetobacter calcoaceticus, and Pseudomonas were the most frequently identified bacteria.
Scopulariopsis, Aspergillus, Penicillium, and Candida were the most numerous fungi.
