Abstract
The quality of the morphological-biochemical identification of P. aeruginosa affects the results of group determination with anti-O-sera to a great extent. Out of 563 isolates classified as P. aeruginosa on the basis of colonial morphology, hemolysis, pigment formation, odor, gram stain and oxidase test, 84.2% reacted with 1 monovalent antiserum. Out of 498 strains which are more precisely identified by additional use of the Oxi/Ferm tube-system, 94.0% are clearly classified. The O-antigen determination is not appropriate for inter-species differentiation of P. aeruginosa, due to common antigens of P. aeruginosa related species.
