[Pseudomonas: microbiological aspects and sensitivity to tobramycin and gentamycin]

97 Strains of Pseudomonas, which were isolated from patients at the hospital of Cremona, have been examined in order to evaluate the validity of some identification tests together with the API 20 system. The authors have also compared the activity of gentamicin with that of tobramycin against these strains isolated recently and strains that had been previously isolated (1976) at the same hospital. The decrease in tobramycin's activity was higher than that of gentamicin.
