1. Nonhuman data suggest that in some strains of Pseudomonas aeruginosa, azithromycin can Antagonize tobramycin

2. An attempt was made to reduce the risk of infection following liver transplantation by means of selective bowel decontamination with tobramycin, polymyxin E and amphotericin B, as well as short-term systemic antibiotics with cephotaxim and tobramycin.

3. Mean peek serum concentrations of tobramycin occur between 30 and about 60 minutes after intramuscular administration.

4. Results: Antibiotic resistance existed in 100% of those 39 Strains of stenotrophomonas maltophilia, when tested with aztreonam, imipenem and tobramycin.
