JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 359 OP 360 DO 10.1136/jcp.31.4.359 VO 31 IS 4 A1 M Rahman YR 1978 UL http://jcp.bmj.com/content/31/4/359.abstract AB A strain of Clostridium welchii produced spores in ordinary blood agar plates. Investigations confirmed that it was the character of this particular strain and that the laboratory media were not inducing sporulation. During a period of 12 months a total of 100 strains of Cl. welchii were studied. None of them produced spores in ordinary laboratory media and conditions when examined microscopically.
