Eligibility criteria:
Inclusion Criteria:

Patients with probable or definite diagnosis of uncomplicated gram positive bacteremia that have at least one positive blood culture including 20 patients with Staphylococcus aureus and the other 20 patients will include any of the following organism ( CNS, Enterococci, streptococci, pneumococci, Corynebacterium, and Propionibacterium or Bacillus species).If the positive blood culture involves a commensal skin organism such as CNS, Corynebacterium, Propionibacterium, Micrococcus and Bacillus, then at least > 100 colonies/ml will be required or a time to positivity =/< 16 hours (as it has been shown to reflect a high grade bacteremia), or two positive blood cultures. (Time to positivity of a blood culture bottle is recorded in the microbiology laboratory by the automatic culture detector (Bactec 9240 and Bactec Plus Aerobic/F; Becton Dickinson) which records culture positivity every 15 min according to changes in fluorescence related to microbial growth).
Patients must have at least two signs of sepsis from the list below, in any combination at any time, within 48 hours prior to Telavancin therapy: a. Core temperature =/>38.0 degrees C or =/<36.0 degrees C, measured orally, rectally, tympanic ally or via a central catheter. If auxiliary add 0.5 degrees C to the measured temperature; b. Pulse rate =/> 100 beats/min.; c. Respiratory rate =/> 20/min.; d. WBC count =/>12,000/mm^3, =/<4,000/mm or differential count showing >10% band forms; e. Systolic blood pressure =/<90 mm Hg. Patient will still be eligible for the study if the participants white blood cell count (WBC) is outside normal limits due to chemotherapy treatment or underlying conditions.
Male or non-pregnant, non-lactating females with an age of greater than or equal to 18 years.
Signed informed consent.
Female patients must be at no risk for pregnancy for one of the following reasons: - Postmenopausal for at least one year - Post-hysterectomy and/or post-bilateral ovariectomy - If of childbearing potential, having a negative serum human chorionic gonadotropin (hCG) pregnancy test with in 5 days prior to enrollment and be using a highly effective method of birth control throughout the course of the study. Reliable sexual abstinence throughout the course of the study is acceptable as a highly effective method of birth control for the purposes of this study.

Exclusion Criteria:

Estimated Serum Creatinine Clearance <30 mL/min (according to Cock-Gault-formula using ideal body weight) at the time gram positive bacteremia was diagnosed unless the patient is on dialysis.
Bilirubin >4x the upper limit of normal at the time gram positive bacteremia was diagnosed.
Treatment with an antibiotic, such as vancomycin, linezolid, tigecycline or Telavancin, effective against resistant gram positive bacterial infections, such as methicillin resistant staphylococci, for more than 48 hours within 72 hours of study medication initiation, unless treatment failed that is defined as a persistent fever and/or leukocytosis for 72 hours or longer of appropriate antibiotics treatment.
History of hypersensitivity to lipoglycopeptides.
Presence of deep-sited intravascular source of infection with same organism cultured from blood, e.g. endocarditis (as evidenced by vegetations on an echocardiogram), or septic thrombosis.
Presence of a prosthetic valve.
Oliguria defined as urine output of <20 cc/hour averaged over 24 hours.
