[Comparative bacteriostatic and bactericidal activities of mezlocillin against Listeria (author's transl)]. 1982

A L Courtieu, and H B Drugeon, and S Billaudel, and S S Chung

The bacteriostatic activity of mezlocillin was compared with those of benzylpenicillin, ampicillin, amoxicillin, carbenicillin and cephalothin against 197 strains of Listeria monocytogenes, including 18 laboratory strains belonging to various serotypes. The most active antibiotics were benzylpenicillin and amoxycillin (0.25 micrograms/ml inhibited 100% of the strains), followed by ampicillin (0.5 micrograms/ml); 98% of the strains were inhibited by mezlocillin 1 micrograms/ml. The bactericidal activity of mezlocillin was compared with that of ampicillin against 10 strains of Listeria. After 6 or 24 hours of incubation, the antibiotics had weak bactericidal activities. After 48 hours, MICs and MBCs were almost identical. The bactericidal activity of mezlocillin was one dilution greater than that of ampicillin.

UI	MeSH Term	Description	Entries
D008089	Listeria monocytogenes	A species of gram-positive, rod-shaped bacteria widely distributed in nature. It has been isolated from sewage, soil, silage, and from feces of healthy animals and man. Infection with this bacterium leads to encephalitis, meningitis, endocarditis, and abortion.
D008802	Mezlocillin	Semisynthetic ampicillin-derived acylureido penicillin. It has been proposed for infections with certain anaerobes and may be useful in inner ear, bile, and CNS infections.

D010406	Penicillins	A group of antibiotics that contain 6-aminopenicillanic acid with a side chain attached to the 6-amino group. The penicillin nucleus is the chief structural requirement for biological activity. The side-chain structure determines many of the antibacterial and pharmacological characteristics.

D002511	Cephalosporins	A group of broad-spectrum antibiotics first isolated from the Mediterranean fungus ACREMONIUM. They contain the beta-lactam moiety thia-azabicyclo-octenecarboxylic acid also called 7-aminocephalosporanic acid.
