title: Pseudomonas monteilii sp. nov., isolated from clinical specimens.
abstract: We propose the name Pseudomonas monteilii for a new species of gram-negative, rod-shaped, motile bacteria that were nonhemolytic on blood agar and were isolated from clinical sources. The 10 strains of P. monteilii were incapable of liquefing gelatin. They grew at 10 degrees C but not at 41 degrees C, produced fluorescent pigments, catalase, and cytochrome oxidase, and possessed the arginine dihydrolase system. They were capable of respiratory but not fermentative metabolism. They did not hydrolyze esculin or starch and were able to use benzylamine, alpha-aminobutyrate, D-ribose, L-arabinose, butyrate, valerate, isovalerate, isobutyrate, inositol, phenylacetate, D-alanine, and amylamine. They possessed L-phenylalanine arylamidase, L-lysine arylamidase, L-alanine arylamidase, gamma-glutamyl-transferase, glycyl-phenylalanine arylamidase, L-tryptophan arylamidase, glycyl-L-alanine arylamidase, esterase C4, esterase C6, esterase C8, esterase C9, esterase C10, and esterase C18. DNA relatedness studies revealed that P. monteilii strains formed a homogeneous DNA hybridization group. A total of 57 strains representing previously described or partially characterized taxa belonging to the genus Pseudomonas were 6 to 54% related to P. monteilii. The highest hybridization values were obtained with strains belonging to or related to Pseudomonas putida biovar A. The average G+C content of the DNA was 60.5 +/- 0.5 mol% for four of the P. monteilii strains studied. The type strain of P. monteilii is CFML 90-60 (= CIP 104883); it was isolated from bronchial aspirate and has a G+C content of 60 mol%. The clinical significance of these organisms is not known.
