Clindamycin resistance among MRSA and MSSA strains.

Susceptibility pattern (phenotypes)	E	CD	D-test	MSSA		MRSA		Total S. aureus
				HIV-infected () (no. (%))	Non-HIV () (no. (%))	HIV-infected () (no. (%))	Non-HIV () (no. (%))	() (no. (%))
Inducible MLSB-(iMLSB)	R	S	Positive	17 (24.6)	4 (9.5)	7 (63.6)	2 (66.7)	30 (24)
Constitutive MLSB-(cMLSB)	R	R	Negative	11 (15.9)	5 (11.9)	3 (27.3)	0	19 (15.2)
MSB	R	S	Negative	21 (30.4)	11 (26.2)	1 (9.1)	1 (33.3)	34 (27.2)
Susceptible	S	S	Negative	20 (28.9)	22 (52.4)	0	0	42 (33.6)

Key: R = resistant, S = sensitive, E = erythromycin, CD = clindamycin, MS_B = macrolide–streptogramin B, MLS_B= macrolide–lincosamide–streptogramin B.
