Resistance to penicillin-streptomycin synergy among clinical isolates of viridans streptococci.
Viridans streptococci are thought to be highly susceptible to penicillin and streptomycin. We recently encountered a unique group of 15 isolates from South Africa epidemiologically related to the isolation of penicillin-resistant pneumococci. These organisms were highly resistant to penicillin (PCN) (minimal inhibitory concentration, 1 to 32 micrograms/ml) and streptomycin (SM) (minimal inhibit...
متن کاملShort-term intramuscular therapy with procaine penicillin plus streptomycin for infective endocarditis due to viridans streptococci.
Thirty-three patients with viridans streptococcal infective endocarditis were treated for two weeks with intramuscular procaine pencillin, 1.2 million units every 6 hours, plus streptomycin, 500 mg intramuscularly every 12 hours. Nine patients (27%) had infections with relatively penicillin-resistant microorganisms (MIC greater than 0.1 microgram/ml or MBC greater than or equal 3.12 microgram/m...
متن کاملTolerance to penicillin in streptococci of viridans group.
Tolerance to penicillin was investigated in 40 isolates of optochin-resistant, alpha-haemolytic streptococci. Thirteen strains exhibited tolerance to penicillin (MBC:MIC ratio greater than or equal to 32) when stationary phase inocula were used, but only seven strains retained the tolerance phenotype in experiments with logarithmic phase inocula. There was a striking association between toleran...

Perry, Dennis (Northwestern University Medical School, Chicago, Ill.) and Hutton D. Slade. Transformation of streptococci to streptomycin resistance. J. Bacteriol. 83:443-449. 1962.-A total of 43 strains of streptococci, belonging to serological groups A, B, C, D, E, F, G, H, K, L, M, N, O, and Q, and three ungroupable strains were exposed to deoxyribonucleic acid (DNA) extracted from streptomy...
متن کاملErythromycin and penicillin resistance mechanisms among viridans group streptococci isolated from blood cultures of adult patients with underlying diseases.
The aim of the study was to evaluate the species distribution, antimicrobial susceptibility and erythromycin-penicillin resistance mechanisms of viridans streptococci (VGS) isolates from blood cultures of adult patients with underlying diseases. Fifty VGS blood culture isolates were screened for their antibiotic susceptibilities against penicillin G, erythromycin and tetracycline by E-test. Cli...
