title: Effect of flaming cotton-plugged tubes upon the contamination of media during culture transfers.
abstract: The effect of flaming the mouth of cotton-plugged broth tubes upon the contamination of media during culture transfers was studied. It was shown that flaming did not reduce contamination significantly either under usual laboratory conditions or when the laboratory atmosphere had been seeded with a test organism so as to achieve higher rates of colony-forming settling particles.
