ABSTRACT
Two episodes of unexpected and widely spread colonisation of Pseudomonas aeruginosa in a hospital urged us with a series of measures concerning personnel and environmental hygiene and prophylaxis. We referred on the microbiological researches made on nine stories of the hospital building in which the microorganism settled and the countermeasures were adopted. The isolates proved to have a strong resistance to the various types of disinfectant we used and it was particularly difficult to clean wash-hand-basins and some medical tests. The AA. think that carefully instructing the staff in the hospital on bacterial biology and their channel of diffusion, and on the appropriate measures to avoid and fight them, could give better results compared to those we actually obtain by simply disinfecting the environment.

We observed two episodes of Pseudomonas aeruginosa colonisation taking place in a Hospital. This organism was isolated in a pure culture from the faeces of 41 newborn children, many patients and from a large part on the obstetrics and pediatry division's staff. The AA. investigated the ways of spreading of this germ which caused both in the adults and the babies, no sign of illness. Biotypes one causing the first episode and the other related to the second one were isolated them showed a wide spectrum of resistance to several antibiotics and they of disappeared after accurate measures of hygiene concerning persons and places were adopted.
