SUMMARY: Two strains of rapidly growing spore-forming bacteria were obtained from cultures of and identified as so-called ‘form 2 mycobacteria’ (Csillag, 1961). The properties of these and of two similar strains received from Dr A. Csillag were investigated, and compared with those of NCTC strains of the genus All four ‘form 2’ strains were almost identical in character, and differed from in many respects, rendering it highly unlikely that they were genetically derived from the mycobacterial cultures in which they were found. They were identified as strains of It is considered that ‘form 2’ organisms are not part of a complex mycobacterial life-cycle, as has been suggested, but are contaminants.
