Meanings of penicillin tolerance in English

We explored the possibility that penicillin tolerance could explain this phenomenon.

Transconjugants carrying high-level resistance to kanamycin exhibited characteristics of penicillin tolerance.

A total of 30 clinical isolates of group B streptococci were studied for penicillin tolerance in vitro.

This method promises to be of value in the further characterization and understanding of penicillin tolerance in vitro and in vivo.

These findings suggest that the genetic basis for penicillin tolerance is related to that for high-level resistance to kanamycin in group A streptococci.

Of 189 streptococcal isolates tested by the gradient replicate plate method for penicillin tolerance, 18 (10%) were tolerant.

Penicillin tolerance was recognized by the gradient-replicate plate method and by time-kill experiments with penicillin concentrations of 16 times the minimal inhibiting concentrations.
