Pseudomonas costantinii sp. nov., another causal agent of brown blotch disease, isolated from cultivated mushroom sporophores in Finland.
Pathogenic bacteria are frequently associated with mushroom sporophores exhibiting brown blotch disease symptoms. These bacteria belong mainly to Pseudomonas tolaasii or occasionally to 'Pseudomonas reactans'. Although a group of isolates originating from some Finnish mushroom farms satisfied the two characteristic criteria for diagnosis of infection with P. tolaasii (i.e. yielding a typical brown blotch symptom on Agaricus bisporus sporophores and producing a typical white line in agar when streaked towards the 'P. reactans' LMG 5329 inducing strain), results based on numerical taxonomy, siderotyping, DNA-DNA hybridizations and 16S rDNA phylogenetic analyses supported the view that these isolates constituted a novel species within the genus Pseudomonas, Pseudomonas costantinii. The type strain is PS 3a(T) (= CFBP 5705(T) = HAMBI 2444(T)).
