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 کاملProperties of cephalosporinase from Proteus morganii.
The cephalosporin beta-lactamase (cephalosporinase) was purified from a strain of Proteus morganii which showed resistance to cephalosporins. The optimal pH was about 8.5, and the optimal temperature was 40 degrees C. The isoelectric point was 8.7 and the molecular weight was estimated to be about 41,000 from sodium dodecyl sulfate-acrylamide gel electrophoresis. The enzyme activity was inhibit...
متن کاملPurification and properties of beta-lactamase from Proteus morganii.
The cephalosporin beta-lactamase was purified from a strain of Proteus morganii that showed resistance to beta-lactam antibiotics and produced the enzyme constitutively. The purified enzyme preparation gave a single protein band on polyacrylamide gel electrophoresis and consisted of a single polypeptide of molecular weight 38,000 to 40,000 from gel filtration of Sephadex G-100 and sodium dodecy...
متن کاملFunction of pyridoxal phosphate in desulfhydrase systems of Proteus morganii.
It has been reported (1) that cystine is metabolized by resting cells of Proteus vulgaris and Proteus morganii to pyruvate, ammonia, and hydrogen sulfide, Toluene-killed cells of P. morganii also carried out the reaction and to a lesser degree attacked homocysteine, yielding hydrogen sulfide, ammonia, and some unidentified product. Inasmuch as the use of toluene-killed cells may not obviate ent...
