Abstract
L FORMS obtained from group A Streptococci are osmotically fragile. Suspensions of the L form, which lacks the rigid bacterial cell wall, in osmotically unprotective environments results in structural disintegration and loss of viability1. A paucity prevails in the literature, however, concerning the effect of temperature and pH on the integrity of the L form in its protective growth medium. This communication deals with a comparison of the effect of such alterations of the growth environment on the structural stability of a group A β-haemolytic Streptococcus and a derived stable L form obtained from it with the aid of penicillin.
