The authors make a bibliographical review of methods for studying the microbiological contamination of closed atmosphere. In a first part, they study the origins of bacterial emission (emissions from nose and pharynx, aerosolization by hospital hands manipulations, skin's emissions). In a second part, the study concern the measure of atmospheric contamination. The authors insist on the correlation may be existed between the counting of all dimensions particles and the bacteria's presence in air. They analyse in details the biological methods of measure (sedimentation, centrifugation, filtration impact) and suggest a room classification according to theirs biological contaminations.
