Biotypes of Proteus rettgeri.
Examination of 729 isolates of Proteus rettgeri showed that 674 reacted positively in tests for phenylalanine deamination, indole production, growth on citrate, and acid production from meso-inositol, and negatively for L-ornithine decarboxylation and acid production from lactose, maltose, D-xylose, and L-arabinose. Only 51 isolates differed in one, and four differed in two of these ten reactio...
متن کاملl-amino acid oxidases of Proteus rettgeri.
Proteus rettgeri has been found to contain two separable 1-amino acid oxidases. Both enzymes are particulate in nature, neither being ribosomal bound. One of these enzymes appears to have broad specificity, being active toward monoaminomonocarboxylic, imino, aromatic, sulfur-containing, and beta-hydroxyamino acids. The other enzyme has more limited specificity, catalyzing the oxidative deaminat...
متن کاملA Serological Study of Proteus Rettgeri and Similar Organisms.
In 1942 a report was made on the studies of a group of citrate-positive organisms, isolated from fecal specimens in the course of examinations for enteric pathogens, that could not be classified biochemically or serologically in any of the established groups (Cope and Kilander, 1942). They were gram-negative anaerogenic bacilli, resembling shigellae in most of their biochemical reactions. Lacto...
متن کاملBiochemical characteristics of lactose-fermenting Proteus rettgeri from clinical specimens.
250-ml Florence flasks. The mature cultures were centrifuged and the cells resuspended in 1 to 2 ml of the supernatant fluid. Except for the tubes in which the suspensions were dried, the drying technique was then carried out as with leptospirae. Briefly, small volumes (0.04 ml) of equal parts of the treponemal suspension and 20% glucose were dried from the liquid state in vacuo over P205. The ...
متن کاملTransduction of R factors in Proteus mirabilis and P. rettgeri.
Phage 34 transduces some R factors to Proteus mirabilis strain 13. These transductants can transmit the R factor by conjugation. Transduction frequencies vary from I x I ~-~/plaque-forming unit (p.f.u.) adsorbed (higher than .chromosomal marker transduction) to 5 x Io-8/p.f.u. adsorbed. Transduced drug resistance markers of other R factors were detected only in the presence of resident$factors ...
