Classification, identification, and clinical significance of Proteus, Providencia, and Morganella.
This review presents the current taxonomy of the genera Proteus, Providencia, and Morganella, along with the current methods for the identification of each species within the three genera, incorporating both conventional biochemical and commercial methods. While all of these organisms are ubiquitous in the environment, individual case reports and nosocomial outbreak reports that demonstrate the...
متن کاملSynergy between cephalosporin and aminoglycoside antibiotics against Providencia and Proteus.
Clinical isolates of Providencia and Proteus with relative aminoglycoside resistance were tested for susceptibility to combinations of gentamicin or tobramycin with cephalothin or cefazolin. The minimal bactericidal concentration of aminoglycoside for one-third of the strains was reduced by fourfold or more in the presence of one-fourth of the minimal bactericidal concentration of either cephal...
متن کاملUnusual Enterobacteriaceae. "Proteus rettgeri" that "change" into Providencia stuartii.
A blood culture bottle from a patient with bacteremia contained both Proteus rettgeri biogroup 5 and Providencia stuartii (described in Bergey's Manual of Determinative Bactiology [8th ed., 1974] as Proteus inconstans), which had the same unusual antibiotic resistance pattern. Single colonies of this P. rettgeri biogroup 5 isolate were shown to produce urea- clones. If current taxonomy is used,...
متن کاملPolymorphism of Esterase Isozyme Zymograms of Melozdogkve Populations Detected by Phastsystem
Esterase isozyrne patterns obtained with an automated electrophoretic apparatus have been used to detect phenotypic variability of forty-one Meloidogyne populations collected from countries throughout the world. Three previously undetected phenotypes have been found along with those commonly ascribed to the four most diffused species M. iucognita, M. jauanica, M. arenaria and M. hapla. Two of s...
متن کاملMolecular characterization of the genera Proteus, Morganella, and Providencia by ribotyping.
The so-called Proteus-Providencia group is constituted at present by three genera and 10 species. Several of the recognized species are common opportunistic pathogens for humans and animals. Different methods based on the study of phenotypic characters have been used in the past with variable levels of efficiency for typing some species for epidemiological purposes. We have determined the rRNA ...
