The diagnosis, epidemiology and control of urinary infection in urology and gynaecology.

In a study of the urine after urological operations, quantitative bacteriological criteria for the diagnosis of infection were determined. The bacteria responsible for urinary infection after urological or gynaecological procedures sometimes came from the same patient, but more often came from other patients by cross-infection. The principal final route of entry was the urethra or the indwelling catheter lying in it.

The colicine typing of coliform bacilli in the study of cross-infection in urology.

Three hundred and fourteen strains of coliform bacilli (79 Klebsiella and 235 E. coli), mostly isolated from urine, were investigated for their production of, or sensitivity to, certain colicines. Only one Klebsiella strain showed colicine activity, but in 204 of the E.
