抄録

Ticarcillin, a new semisynthetic penicillin, was investigated on the antibacterial activity chiefly against gram-negative bacilli as Ps. aeruginosa derived from blood, and on the combination effect with aminoglycoside antibiotics to compare carbenicillin and sulbenicillin. Results obtained were as follows.<BR>1. Ticarcillin showed stronger antibacterial activity than carbenicillin and sulbenicillin against all species of Ps. aeruginosa, Enterobacter and Serratia.<BR>2. Ticarcillin and gentamicin or dibekacin were found to be synergistically bacteriostatic against all strains of Ps. aeruginosa, the effect being 8-16 times stronger compared with a single administration. Compared with sulbenicillin, ticarcillin was shown to inhibit the growth of Ps. aeruginosa equally to sulbenicillin with 1/2 concentration of sulbenicillin, if concentration of gentamicin was fixed.
