Pathogenic bacterial infections have become a major health problem worldwide. New antimicrobial agents are urgently needed to overcome this problem. In this study, antibacterial activity of Nigella sativa seed extract against some pathogenic bacterial strains (Streptococcus pyogene, Pseudomonas aeruginosa, klebseilla pneumoniae and Proteus vulgaris) was evaluated. Methanol extract at the concen...

A method of typing isolates of Proteus mirabilis and Proteus vulgaris is described based on the sensitivity of the organisms to bacteriocine. Twelve standard proteocine producing strains were selected from a large number of isolates tested, and from these liquid proteocine preparations were prepared. The sensitivities of 1805 isolates to these 12 preparations were then determined and none was f...

Analysis by 1H and 13C nuclear magnetic resonance (NMR) spectroscopy demonstrated that the O-specific polysaccharides of Proteus mirabilis PrK 42/57 and P. vulgaris PrK 43/57 are structurally similar to that of P. vulgaris PrK 44/57 and different from the polysaccharide of P. mirabilis PrK 41/57 studied earlier. The lipopolysaccharides of these strains were tested using enzyme immunosorbent ass...

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...

The enzymatic degradation of chondroitin sulfuric acid can be catalyzed by purified bovine testicular hyaluronidase (1, 2) and by an enzyme preparation from Flavobacterium heparinum (3). Dodgson and Lloyd (4) obtained a chondroitinase from Proteus vulgaris that converted chondroitin sulfuric acid to the disaccharide, N-acetylchondrosin sulfate. Previous work from this laboratory (5) has confirm...

The investigation was conducted with methanolic extract of Murraya koenigii L for its anti bacterial, phytochemical screening and antioxidant capacities. Antibacterial activity of the extract was evaluated against various Grampositive and Gram-negative bacteria using agar well diffusion technique. For phytocehmical screening such as flavonoids. alkaloids, resins, glycosides, tannins, saponins, ...

Thirteen indole-producing, swarming strains of Proteus were identified by additional biochemical testing as being Proteus mirabilis. These strains were characterized by 40 biochemical tests and by susceptibility testing to 11 antibiotics. All produced ornithine decarboxylase and were susceptible to members of the penicillin-cephalosporin groups of antibiotics. These indole-positive strains are ...

Aron, H. (University of California, Santa Barbara), H. H. Yonenaka, and H. I. Nakada. Glucosamine-6-phosphate degradation by Proteus vulgaris and isolation of phosphoglucosaminisomerase. J. Bacteriol. 87:1123-1128. 1964.-The presence of the enzyme, phosphoglucosaminisomerase, was demonstrated in a strain of Proteus vulgaris. Fructose-6-phosphate and ammonia were shown to be the primary reaction...
