The ethiology of the infections acquired in the City Hospitals and the behaviour of isolated bacteria by means of ten (10) antimicrobians, were demonstrated. The bacteriologic methodology was followed which conducted to the identification only of the bacterian species, except Stafilococci that were individualized through phagotyping. A hundred and seventy one (171) infectious processes in hospitals were collected from September, 1974 to May, 1975 from these processes, two hundred and eleven (211) microorganisms were isolated, 72.99% being Gram negative and 27.05% Gram positive. A high level of antibiotic resistence was verified. The Gram negative bacteria presented smaller resistence to Gentamicine and the Gram positive, a better sensibility to Cefalotine, Fosfomicine and Gentamicine. An analysis of the results allows us to foresee serious difficulties as regards the action of antimicrobians on bacteria, and also the intense spread of Gram negative bacteria, specially Escherichia coli and Pseudomonas.
