Evaluation of a wipe surface sample method for collection of Bacillus spores from nonporous surfaces.

abstract：:A simplified X-ray film method for detecting bacterial production of Hgo by Escherichia coli was developed. There was excellent agreement of results between this X-ray film method and radioactive mercury volatilization assays. Although not quantitative, the X-ray film method has the advantages of being rapid, simple t...
