Outer membrane permeability of non-typable Haemophilus influenzae.
The permeability to cephaloridine was studied in five Haemophilus influenzae strains (four non-typable and one type b) using the Zimmermann and Rosselet method. The beta-lactamase activity was due to a plasmid-encoded TEM-1 enzyme. High permeability coefficients were measured in all strains examined. No great differences in permeability coefficients were found, even between strains with marked differences in OMP electrophoretic profiles.
