220 strains of Streptococcus faecalis (103 isolated in Poland and 117 in Federal Republic of Germany), were tested for antibiotic susceptibility to 32 antimicrobial agents by an agar dilution technique. The most effective in vitro appeared to be ampicillin, penicillin G, and a combination (1:1) of penicillin and streptomycin. Partly effective were also macrolide antibiotics, trimethoprim + sulfamethoxazole and 5 tetracyclines. Other antibiotics, including 5 cephalosporin derivatives, 5 aminoglycoside antibiotics, 2 lincomycins, 2 polymyxins, chloramphenicol and fucidin, appeared practically ineffective in vitro. The effectiveness of antimicrobials in vitro was considered on the basis of standard bioavailability of antimicrobial agents. No differences in antibiotic susceptibility patterns of any practical significance were found, when strains isolated in Poland and the Federal Republic of Germany were compared.
