Properties of the penicillin binding component of Micrococcus pyogenes.

The antibiotic effect of penicillin on bacterial cells is known to involve the inhibition of a process necessary for cell division but not primarily connected with respiration (Florey et al., 1949). Previous work in which the primary bacteriostatic action of penicillin has been apparently identified with a disturbance in amino acid (Gale, 1952) or nucleotide metabolism (Gros and Macheboeuf, 195...

In the past, S. pneumoniae was uniformly susceptible to penicillin, which remained the drug of choice for serious infections. However, since the mid-1960s, resistance to penicillin, which was first reported...

Penicillin resistant pneumococcus.

Resistance to other antimicrobial agents and chloramphenicol has also been reported. 4,5 Multiple resistant strains have been responsible for infection with a high mortality rate. 5 To our knowledge, isolation of penicillin resistant pneumococci has not been documented in this region. We report the isolation of a penicillin resistant strain from the throat of an eleven-month old baby boy and th...

Carriage of penicillin resistant pneumococci.

A survey of 303 urban and 156 rural children showed nasopharyngeal carriage of relatively resistant Streptococcus pneumoniae organisms in 14.2% and 19.2% of children, respectively. These organisms have minimum inhibitory concentrations for penicillin in the range of 0.12-1 microgram/ml. An analysis of 40 relatively resistant S. pneumoniae strains showed resistance to co-trimoxazole in 47.5%, tr...

Epidemiology of penicillin resistant Neisseria

Objective-To study the epidemiology of Neisseria gonorrhoeae that exhibit both chromosomal and plasmid-mediated resistance to penicillin. Materials and methods-A total of 1589 strains of N gonorrhoeae isolated from patients attending St Mary's Hospital, London were tested for both their susceptibility to penicillin and for their auxotype and serotype. Results-Of the 940 non-penicillinase produc...
