Respiratory tract infections and skin and soft-tissue infections frequently are caused by gram-positive cocci, and treating these infections with standard antibiotics has recently become problematic. Many of the primary pathogens causing these infections are now resistant to current standard treatment regimens. In addition, the frequency of these infections is increasing, particularly among patients with complex medical conditions. ⋯ Linezolid, the first approved oxazolidinone, has enhanced activity against gram-positive organisms. Recent results of 5 large, randomized, phase 3 trials evaluating linezolid for the treatment of community-acquired pneumonia, nosocomial pneumonia, and uncomplicated and complicated skin and soft-tissue infections are encouraging and indicate that linezolid is as effective as standard comparator agents as therapy for these infections. Thus, the recent availability of linezolid offers clinicians a promising new agent for the treatment of serious gram-positive bacterial infections.

The transmission of infection by a cadaver donor organ can result not only in loss of the allograft but also in death of the immunosuppressed recipient. Despite the shortage of cadaver organ donors, every donor must be evaluated thoroughly for the potential transmission of infectious disease, because the consequences of the organ donor events can have a profound effect on the transplant outcome. This review summarizes current knowledge about serological screening of organ donors to determine the suitability of organs from cadaver donors for transplantation.
