The effects of subinhibitory concentrations of various antibiotics on phagocytosis of Streptococcus faecalis.
This study reports the effects of subinhibitory concentrations of the antibiotics, clindamycin, gentamicin, moxalactam, and penicillin G, against 6 blood isolates of Streptococcus faecalis to determine possible enhancement of phagocytosis. In addition, combinations of penicillin G plus streptomycin, penicillin G and gentamicin, and clindamycin plus gentamicin were studied to determine synergistic growth inhibition. Results suggest no observable effect in phagocytosis from subinhibitory concentrations of the studied antibiotics singly or in combination. The number of viable intracellular Str. faecalis were also not affected by pre-treatment with antibiotics.

Establishment of minimum inhibitory concentrations of cefoperazone for control and reference anaerobic organisms.
The minimum inhibitory concentrations of cefoperazone were determined in a collaborative study for eight National Committee for Clinical Laboratory Standards control and reference strains of anaerobic bacteria by agar and microdilution techniques with several types and sources of media. Recommended minimum inhibitory concentrations for the control strains, Bacteroides fragilis ATCC 25285 and Bacteroides thetaiotaomicron ATCC 29741, are 32 to 64 micrograms/ml and 64 micrograms/ml, respectively. Clostridium perfringens ATCC 13124 gave inconsistent results, and no value is recommended. Recommended values for reference strains are presented. Modification of media did not significantly change the minimum inhibitory concentrations.
