[Serotypes of Pseudomonas aeruginosa isolated from the hospital environment (author's transl)].

: Pseudomonas, especially after misuse of antibiotics began to play an important part in hospital infections. Pseudomonas was classified by many investigators, starting with Habs, according to their thermo stable (O) antigens. In this study, we examined 41 stains of Pseudomonas aeruginosa, out of 278 samples taken from the hospital, apart from the patients, according to their (O) antigens. We found 6 from Habs 0:11, 4 from Veron 60 BL, 5 from Habs 0:7, 5 from Veron 61B, 6 from Veron 60 BT, 4 from Habs 0:3, and one from Habs 0:5, 0:9, 0:8 and Sandvik serotype II respectively. We couldn't isolate the strains Habs 0:1, 0:2, 0:4, 0:6, 0:10, 0:12, Veron 59AH (0:5 cd) in our hospital.
