A Slit Sampler for Collecting Air-Borne Microorganisms

Thermal precipitation for sampling air-borne microorganisms.

Comparison of bacterial recovery by Reuter centrifugal air sampler and slit-to-agar sampler.

Bacterial recovery by a portable Reuter centrifugal air sampler and a standard Mattson-Garvin slit-to-agar air sampler was compared in a series of experiments. Microbial air quality was monitored in seven typical laboratory locations. Tests showed that the Reuter centrifugal air sampler yielded significantly higher recoveries than did the slit-to-agar unit.

A slit sampler for collecting T-3 bacteriophage and Venezuelan equine encephalomyelitis virus. II. Studies with Venezuelan equine encephalomyelitis virus.

The virus employed was the fourth mouse brain passage of a strain of VEE virus recovered from a human infection in Colombia. The virus was suspended in phosphate buffer soluton (PBS),' pH 7.5, containing 2 per cent normal rabbit serum (NRS) to which antifoam A2 had been added to facilitate aerosolization. The virus suspension was aerosolized with a Collison3 generator in a modified Henderson4 a...

The Collecting of Airborne Microorganisms

Evaluation of slit sampler in quantitative studies of bacterial aerosols.

Quantitative studies were conducted to evaluate the efficiency of the slit sampler in collecting airborne Serratia marcescens and Bacillus subtilis var. niger, and to compare it with the collecting efficiency of the all-glass impinger AGI-30. The slit sampler was approximately 50% less efficient than the AGI-30. This ratio remained the same whether liquid or dry cultures were disseminated when ...
