Radiometric study on the invasion capability of Streptococcus pyogenes A49 L-forms in tissue cultures.
By a radiometric method using C14 labelled amino acid mixture it was established that the Streptococcus pyogenes A49 L-forms cells invade tissue cultures MK and F in a similar degree as parent bacterium cells. The L-form cells are not able to enter the HeLa and Pulmo tissue culture cells but the parent bacterium cells produce well expressed peak of isotope take-up at the 8th hour of the observation.
