Aged or immuno-compromised patients were mostly affected, by pneumonia caused by infection of MRSA, and more than half of the cases were superinfected with glucose-nonfermentative Gram-negative rods including Pseudomonas aeruginosa. These patients were treated with a monotherapy of arbekacin (ABK) by intravenous drip administration or with a combination of ABK and imipenem/cilastatin, ceftazidime or antifungals. The clinical efficiencies were 55.
