Subjects must have received linezolid 600 mg BID for six weeks or greater and be currently on drug (or have received linezolid within 7 days of baseline evaluation).
Subjects who have current signs or symptoms compatible with linezolid toxicity (i.e. optic or peripheral neuropathy) may be enrolled in the study if they are on linezolid at time of baseline evaluation (or have received linezolid within 7 days of baseline evaluation).
Linezolid may be discontinued at any time at the primary physician's discretion and remain on the study.
Women of childbearing potential must use adequate contraception

Subjects who are currently receiving or anticipated to receive another medication, antibiotic or other, that has known potential to produce ocular or neurologic toxicity indistinguishable from that caused by linezolid or lactic acidosis.
Subjects with a history of significant exposure, in the opinion of the investigator and with prior discussion with the medical monitor, to medications known to produce optic or peripheral neuropathy.
Subjects with an active communicable disease (i.e., tuberculosis assessed as currently communicable) and subjects on active treatment for tuberculosis or other mycobacterial disease that include drugs that have known potential to produce ocular or neurologic toxicity.
