title: [Detection of glycosidases in Pseudomonas of the fluorescent group: relation between serotype and glycosidase activities in P. aeruginosa].
abstract: Fluorescent Pseudomonas species (P. aeruginosa, P. fluorescens, P. putida) were tested for the presence of glycosidase activities (alpha-D-glucosidase, beta-D-glucosidase, alpha-D-galactosidase, beta-D-galactosidase, beta-xylosidase, alpha-D-mannosidase, alpha-L-fucosidase, beta-L-fucosidase, beta-D-glucuronidase and N-acetyl-beta-D-glucosaminidase). Some of the investigated glycosidases were always absent, while N-acetyl-beta-D-glucosaminidase was constantly present in all strains; 3 glycosidase activities were observed in association or separately. Serotype O11 of P. aeruginosa was found to be homogeneous with respect to some of those enzymatic activities. Search for beta-D-galactosidase, alpha-D-glucosidase and beta-D-glucosidase may be of diagnostic value in epidemiologic studies of P. aeruginosa.
