method. Thirteen penicillinase-producing strains were isolated, of which four were examined for the presence of plasmids.5 All contained a 3 2 megadalton plasmid in addition to the 2-6 megadalton cryptic plasmid. None contained 4-4 or 24-5 megadalton plasmids. The F-lactamase produced by ...

In order to investigate this the author studied 228 patients with gonorrhoea treated with 0.3 mega units of PAM in 1959 and 825 treated with 0.6 mega units of procaine penicillin in 1961, 1962 and 1963. The relapse (including failure) rate was 16-2......
Each case of gonorrhoea was treated with intramuscular procaine penicillin 2.4 megaunits and the penicillin sensitivity was determined. All 69 of the isolates from patients with PGU were fully sensitive to penicillin (IC50 less than 0.08 iu penicillin per ml). Twenty-eight (10.2%) of 275 cases ...
