Gram-negative bacillary infection, particularly septicaemia, renal, pelvic and abdominal sepsis. Gentamicin remains the drug of choice, but tobramycin may be preferred for Pseudomonas aeruginosa.
How do you classify Gram negative bacteria?
Gram-negative bacteria are classified by the color they turn after a chemical process called Gram staining is used on them. Gram-negative bacteria stain red when this process is used. Other bacteria stain blue.
