Failure of Sulphonamides to Prevent Urinary Infections after Vaginal Surgery

Among less important factors affecting cure, coccal infections were shown to respond best, those due to Bact. coli and Bact. aerogenes well, whereas infections due to Proteus, Ps. pyocyanea, and paracolon bacilli were more resistant to treatment. There was a clear relationship between the in vitro sensitivity of the organism and the outcome of treatment, and the use of laboratory sensitivity tests is advocated to avoid the prescription of inappropriate drugs. For most species identification only is no longer sufficient.
