Abstract
Using Hauduroy''s transfer technic, filtrates from atypical, highly granular, tubercle bacilli transplanted on agar plates regularly yielded minute colonies of partly acid-fast, diphtheroid, pleo-morphic, nonpathogenic bacilli. It was ascertained that they were air contaminators. It is pointed out that they resemble closely certain bacterial forms described by others as cyclostages of tubercle bacilli, and that regularity of occurrence is no valid argument against their being contaminators.
