A penicillin-resistant pneumococcus

The Journal of Pediatrics, 1978
STREPTOCOCCUS PNEUMONIAE has been almost uniformly sensitive to pen!cillin, With minimum inhibitory concentrations of 0.05 Fg/m 1 or less. In 1967, the first pariially resistant strain with an MIC of 0.6/~g/ml, was reported from Sydney, Australia. Since then there have been reports of pneumococci having increased resistance to penicillin, with MICs ...

Penicillin-resistant pneumococcus

Irish Journal of Medical Science, 1988
Penicillin resistant pneumococci are now described world wide, with increasing recognition of the clinical implications of infection with these strains and the laboratory methods required for their identification. In presenting such a case, we suggest thatin vitro sensitivity testing with oxacillin discs affords the best method for detection of ...

Intrinsic Penicillin Resistance in Enterococci

Microbial Drug Resistance, 1996
ABSTRACT Penicillin resistance development in enterococci has been associated with overproduction of a low-affinity penicillin-binding protein (PBP) that is a normal component of the PBP pattern of these bacteria and is apparently able to substitute the functions of the other PBPs. In resistant mutants of

Penicillin Resistance and Autolysis in Enterococci

Microbial Drug Resistance, 1996
ABSTRACT Comparison of several cell wall-related properties of the ATCC 9790 strain and the R40 strain, a penicillin-resistant, PBP5 overproducing strain, and Rev14, a penicillin-hypersensitive, PBP5-deficient strain, is consistent with a role of the genetic element, psr ...

Penicillin Resistance and Aminoglycoside-Penicillin Synergy in Enterococci

Chemotherapy, 2009
Susceptibility to penicillin, vancomycin, imipenem, streptomycin, kanamycin and gentamicin was tested in 130 clinical isolates of Enterococcus spp. by an agar dilution method. Penicillin resistance (MIC > 8 mg/l) was only observed among strains of Enterococcus faecium and Enterococcus raffinosus.

Penicillin-resistant pneumococci

Drugs of Today, 1998
Penicillin-resistant pneumococci are of concern in respiratory tract infections. Currently, nearly all of the "penicillin resistance" to Streptococcus pneumoniae is relative resistance which indicates decreased antibiotic activity in terms of the MIC, but these isolates are still susceptible to sensitive antibiotics given in the usual/high doses.
