A number of air sampling techniques have been developed for the sampling of airborne bacteria. The basic methods employed include sedimentation, impaction upon solid surfaces, impingement into liquids and filtration. A variety of equipment is also available for sampling of airborne particulates. With regard to surface sampling of microbial contamination one of three basic methods is usually employed; swabbing, agar plate impression, or the direct surface agar contact plate method. Illustrations of equipment employing bacterial impaction upon solid surfaces, airborne particulate sampling and direct contact plates are included in this chapter.
