Molecular Basis for the Potent Inhibition of the Emerging Carbapenemase VCC-1 by Avibactam.

abstract：:Sixty-three consecutive streptococcal blood isolates from neutropenic patients, represented mainly by viridans group streptococci, were evaluated in vitro for antibiotic susceptibility. Of these isolates, 79.3% were highly susceptible to penicillin (MIC, less than or equal to 0.12 microgram/ml). Overall, imipenem was ...
