Biochemical Classification of Proteus and Providence Cultures Shaw, Constance and Clarke, Patricia H.,, 13, 155-161 (1955), doi = https://doi.org/10.1099/00221287-13-1-155, publicationName = Microbiology Society, issn = 1350-0872, abstract= Summary: Biochemical reactions of 153 Providence (29911 type) and 63 Proteus cultures were examined. Providence cultures are included in the genus Proteus, as their cultural characters are similar; this relationship is strengthened by the production of l-amino acid oxidase and glutamic acid decarboxylase by both. Proteus inconstans Ornstein nov.comb. is the name proposed for Providence cultures., language=, type=
