Colonies
of M. paratuberculosis
on culture medium without Tween Colonies
of M. paratuberculosis grown on Middlebrook agar media without
Tween are rough in appearance. Tween 80 is a surfactant commonly
used in culture media to accelerate the growth of mycobacteria.
For M. paratuberculosis, Tween 80 can alter the colonial
and cellular morphology.
