Cultural and Serological Phases of Proteus vulgaris

Bacteriophage typing of Proteus mirabilis, Proteus vulgaris, and Proteus morganii.

A bacteriphage typing scheme for differentiating Proteus isolated from clinical specimens was developed. Twenty-one distinct patterns of lysis were seen when 15 bacteriophages isolated on 8 Proteus mirabilis, 1 P. vulgaris, and 1 P. morganii were used to type 162 of 189 (85.7%) P. mirabilis and P. vulgaris isolates. Seven phages isolated on 3 P. morganii were used to type 13 of 19 (68.4%) P. mo...

Isolation and Characterization of Proteus Vulgaris

Identification of Proteus penneri sp. nov., formerly known as Proteus vulgaris indole negative or as Proteus vulgaris biogroup 1.

The name Proteus penneri sp. nov. is proposed for a group of organisms previously called Proteus vulgaris indole negative or P. vulgaris biogroup 1. All of these strains were salicin negative, esculin negative, and chloramphenicol resistant (zone size, less than 14 mm). DNA relatedness studies indicated that when DNA from P. penneri strain 1808-73 was labeled and tested against unlabeled DNA fr...

Isolation of phenylalanine-negative Proteus vulgaris.

Three phenylalanine-negative Proteus vulgaris strains were isolated from three different sources. The significance of these Proteus strains has not been fully recognized.

A Biochemical Study of Proteus Vulgaris

In this study we deal with the cultural properties, the products of growth, the pathogenicity, and the toxicity, of two strains of Proteus vulgaris, Hauser. This is an exceedingly interesting organism on account of its wide distribution, the ease with which it is modified, and because it seems to stand between the true saprophytic and the purely pathogenic bacteria. It has been found under a gr...
