Susceptibility of Staphylococcus aureus, Streptococcus pyogenes and Diplococcus pneumoniae to antibiotics. Comparison of patterns in Poland and Federal Republic of Germany.

One hundred and eighty five strains of Gram-positive cocci were tested for susceptibility to 16 antibiotics, including some newer drugs, by agar dilution technique. Of these, 100 strains (50 each isolated in Poland and Germany) were Staphylococcus aureus, 55 Streptococcus pyogenes, and 30 Diplococcus pneumoniae. Previous investigations of streptococci and pneumococci isolated in Poland and Federal Republic of Grmany, revealed no differences in antibiotic-susceptibility patterns in both countries, which was not the case with staphylococci. Present study demonstrates further evidence for existence of differences in antibiotic-sensitivity of staphylococci, depending of their geographical origin, and presents actual state of susceptibility to antibiotics of Streptococcus pyogenes and Diplococcus pneumoniae.

Susceptibility of Streptococcus faecalis to 32 antimicrobial agents. Comparison of patterns in Poland and Federal Republic of Germany.

Two hundred and twenty 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 agar dilution technique. Most effective in vitro appeared ampicillin, penicillin G, and a combination (1:1) of penicillin and streptomycin. Partly effective were also macrolide antibiotics, trimethoprim + sulfamethoxazole and five tetracyclines. Other antibiotics, including five cephalosporin derivatives, five aminoglycoside antibiotics, two lincomycins, two polymyxins, chloramphenicol and fucidin, appeared practically ineffective in vitro. 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 Federal Republic of Germany were compared.

Susceptibility of clinically important gram-negative bacilli to 15 antibiotics. Comparison of patterns in Poland and Federal Republic of Germany.

Three hundred and sixty strains of Gram-negative bacilli (Escherichia coli, Salmonella enteritidis, Enterobacter cloacae, Providencia, indole-positive and indole-negative Proteus, Klebsiella pneumoniae, Pseudomonas aeruginosa and Serratia marcescens), were isolated by random in Poland and Germany, and tested by agar dilution method for susceptibility to 15 antimicrobial agents, including six cephalosporin derivatives, colistin, gentamycin and tobramycin, three newer tetracyclines, ampicillin and carbenicillin, and a combination of trimethoprim and sulfamethoxazole. This investigation revealed existence of growing antibiotic-resistance of Gram-negative bacilli to all antimicrobial agents. A detailed analysis of this problem is described and a list of agents effective in vitro is presented. Some evidence has been found concerning possible existence of geographical differences in antibiotic-susceptibility patterns of strains of Gram-negative bacilli, isolated in Poland and Federal Republic of Germany.
