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...
متن کاملThe Journal of Antibiotics Ps-5 Inhibition of a B-lactamase from Proteus Vulgaris*
Inhibition of Proteus vulgaris B-lactamase by a new B-lactam antibiotic, PS-5 was studied kinetically. There were two stages of inhibition. In the early stage, PS-5 inhibited the Blactamase by formation of a MICHAELIS-complex, and showed a competitive inhibition pattern with Kj-value of 0.22 uM (substrate, cephaloridine). After the formation of a MICHAELIScomplex between PS-5 and the enzyme, PS...
متن کاملKinetic studies on the inhibition of Proteus vulgaris beta-lactamase by imipenem.
Imipenem was found to inhibit Proteus vulgaris beta-lactamase in a progressive manner. Kinetic experiments confirmed that the inactivated enzyme was not completely recovered after intact imipenem had been exhausted.
متن کاملIdentification 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...
متن کاملTetranitro-blue Tetrazolium Reduction in Proteus Vulgaris
In Bacillus subtilis the reduction of potassium tellurite and of tetranitro-blue tetrazolium (TNBT) give comparable results: reduced products appear deposited in particular membranous organelles. For this reason these specialized organelles are considered to be chondrioids (1-3). In the Gram-negative Proteus vulgaris similar membranous structures were never observed by us (4, 5). Therefore it i...
