Survival of toxigenic Pasteurella multocida in aerosols and aqueous liquids
Article Abstract:
The survival of toxigenic Pasteurella multocida in aerosols was examined under different relative humidities and suspension compositions. Survival rates were also measured in different liquids at different temperatures. The results showed that the typical survival rates in air were 80% after one minute, decreasing to about 5% at 45 minutes. The viability of the cells were affected by relative humidity only during the initial decline, with the composition of the suspension fluid having no effect on the eventual survival of cells. In liquid media, water and instant ocean were lethal as temperature increased. Nutrient addition served to protect against thermal effects.

Relationships between Mycobacterium isolates from patients with pulmonary mycobacterial infection and potting soils
Article Abstract:
The quantities and identities of soil mycobacteria in aerosols to which patients are exposed are evaluated by culture and molecular analyses of mycobacteria from soil samples provided by patients in order to determine if soils are potential sources of nontuberculous mycobacterial infections. The results have shown that potting soils are potential sources of infection by environmental mycobacteria and hence dust-excluding masks should be used while potting or other activities that generate aerosol with soil.

Quantitative analysis of bacterial aerosols in two different dental clinic environments
Article Abstract:
Contamination of air with microbial aerosols appears to increase during performance of dental treatments, and can spread rapidly into surrounding areas. In a closed dental procedure room and an open multichair clinic, air was collected using a slit-type sampler with blood-supplemented Trypticase soy agar plates before, during, or up to 7 hours after treatments. Aerosols may be produced by use of high-speed drills and ultrasonic scalers, and may be a significant source of infection.
