Cobalt and bacterial growth, with special reference to Proteus vulgaris.
For the past five years we have been engaged in an investigation of the effect of cobalt on the growth and metabolism of bacteria, especially of Proteus vulgaris. The emphasis on Proteus followed requests for aid in the control of growth of this penicillinand sulfa-resistant organism in cases of peritonitis, cystitis, and eye infections. Interest in cobalt as a growth inhibitor of microorganism...

15 صفحه اولSwarming growth and resistance of Proteus penneri and Proteus vulgaris strains to normal human serum.
BACKGROUND Proteus sp. strains isolated from patients with urinary tract infection (UTI) are often insensitive to the bactericidal action of normal human serum (NHS) which poses a clinical problem. The swarming phenomenon is an especially important factor in cases of UTIs gained through the ascending route. Both these virulence factors are connected with the cell surface components of bacteria,...
متن کاملThe Chemical Alteration of a Bacterial Surface, with Special Reference to the Agglutination of B. Proteus Ox-19
The chemical substitution of a bacterial surface has been effected by the addition of benzene sulfonyl chloride to B. proteus OX-19. The substitution of imidazole and amino groups on the bacteria has been followed by the microelectrophoretic method. Concomitant changes in the agglutinability of substituted organisms have been observed, without appreciable change in the antibody-combining capaci...
متن کاملBacteriophage 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...
