Resistant phenotypes in methicillin-sensitive Staphylococcus aureus

Resistant phenotype	Induction test phenotype	ERY susceptibility	CLI susceptibility	No. of isolates	%
iMLSB	D test positive	R	S	30	11.5
MS	D test negative	R	S	50	19.3
cMLSB	R	R	R	40	15.4
No resistance	S	S	S	140	53.8

CLI = clindamycin; cMLSB = constitutive macrolide–lincosamide–streptomycin group B; D test = disk approximation test; ERY = erythromycin; iMLSB = inducible macrolide–lincosamide–streptomycin group B; MS = methicillin sensitive; R = resistant; S = sensitive.
