Cross Infection among Animals Challenged with Bacillus Anthracis

Laboratory Safety in Research with Infectious Aerosols

“…niger. This bacillus could be re¬ covered daily for 9 days from the air of a ventilated cage containing one control monkey and one that had been bodily exposed in a separate aerosol chamber for 1 minute to 1.4 X105 spores per liter of air (26). Guinea pigs similarly tested yielded the bacilli for 18 days (29).…”

Laboratory Design for Microbiological Safety

“…Determining what safety measures to incorporate in the design of infectious-disease laboratories has required much research and study. For instance, it was necessary to understand how laboratory workers become infected, how microorganisms might escape and spread within a building or escape to the surrounding community, how animal cross-infection and culture cross-contamination occurs, and other similar problems (6,10,12). From the results of a number of laboratory hazards studies (1,9,17,18), two concepts emerged that have proved successful in designing biologically safe laboratories.…”
