Phylogenetical relationship based on groE genes among phenotypically related Enterobacter, Pantoea, Klebsiella, Serratia and Erwinia species.

Escherichia, Klebsiella, Enterobacter,Serratia, Citrobacter, and Proteus

Nosocomial Infections: Coliform and Proteus bacilli currently cause 29 percent of nosocomial (hospital-acquired) infections in the United States. In order of decreasing frequency, the major sites of nosocomial infection are the urinary tract, surgical sites, bloodstream, and pneumonias. This group of nosocomial pathogens are responsible for 46% of urinary tract and 24% of surgical site infectio...

Preliminary observations on the rapid differentiation of the Klebsiella-Enterobacter-Serratia group on bile-esculin-agar.

A total of 232 isolates of Enterobacteriaceae and 19 Pseudomonas species were tested on bile-esculin-agar. Only the Klebsiella-Enterobacter-Serratia group produced blackening of the medium.

Klebsiella, Enterobacter, and Serratia: biochemical differentiation and susceptibility to ampicillin and three cephalosporin derivatives.

Three hundred twenty-nine strains of the tribe Klebsielleae were compared by several biochemical tests and by susceptibility to selected antibiotics. Biochemical tests included urease, amino acid decarboxylase, and hydrogen sulfide production; fermentation of lactose and dextrose; motility; and tests in the IMViC (indole, methyl red, Voges-Proskauer, citrate) series. The isolates were: Klebsiel...

Differentiation of Klebsiella-Enterobacter (Aerobacter)-Serratia by biochemical tests and antibiotic susceptibility.

Studies were undertaken for the differentiation of members of the Klebsiella-Enterobacter (Aerobacter)-Serratia division by biochemical tests and antibiotic susceptibility. A total of 67 cultures were tested. Strain identification was readily accomplished with the use of motility tests and arabinose fermentation. In addition, a practical schema, based on sensitivity pattern, proved valuable in ...
