Preclinical findings only; extends basic R-factor model but leaves open relevance to clinical resistance spread.
The study identifies operator-constitutive and repressor-negative mutants of the R factor R100, supporting a simple regulatory model for R-factor-mediated piliation.
David I. Hoar (1970) studied this question. R factor R100 mutants that mediate high-frequency transfer consist of operator-constitutive and repressor-negative classes, supporting a simple regulatory model for piliation.
