[Serological typing in the study of the transport of strains of Pseudomonas aeruginosa in the hospital environment].

Bacteriologic investigations in an operation theatre in the surgical department of an older hospital building in Bucharest detected 14 Ps. aeruginosa strains (10 strains were isolated on the floor of the operation theatre, from the sterile room and wash basins, two strains from the wheels of stretchers and two from the footwear used during the transport of patients). Serologic typing identified the routes of transport of the Ps. aeruginosa species, making it possible to take the necessary control measures.
