The density and size of air-borne Serratia marcescens.
During an investigation of air-borne microorganisms, the net electric charges carried by individual cells at various relative humidities were studied using a Millikan apparatus (1947), a device in which the vertical rates of movement of the cells under gravity and under imposed electric fields were measured. Cell size and charge could have been calculated directly from such measurements if the ...
متن کاملSerratia marcescens.
Over the last 30 years, Serratia marcescens has become an important cause of nosocomial infection. There have been many reports concerning the identification, antibiotic susceptibility, pathogenicity, epidemiological investigations and typing of this organism. Accurate identification is important in defining outbreaks. The API 20E system has been used widely, but is not individually satisfactor...
متن کاملSerratia marcescens
The nucleotide sequence of the proBA operon from a proline-hyperproducing mutant of Serratia marcescens was determined. Two base substitutions were found: one in theproBstructura1 gene, coding for y-glutamyl kinase (GK), and a second one in the promoter region of the operon. The former base substitution led to a change of the predicted amino acid at position 117 from an alanine to a valine in G...
متن کاملSerratia marcescens meningitis.
A case of Serratia marcescens meningitis in a 66-year-old man is reported. The infection occurred 4 weeks after apparently successful otic surgery, and a nidus of infection in the middle ear was established at autopsy. This is the second case of S. marcescens meningitis following ear surgery reported in the English-language literature.
متن کاملChitinases from Serratia marcescens
Serratia marcescens is one of the most effective bacteria for degradation of chitin, a 1,4-β-linked polymer of N-acetyl-β-Dglucosamine (GlcNAc). Chitinolysis by S. marcescens involves at least four enzymes and a chitin-binding protein. Studies of the enzymology and the structures of the enzymes provide insight in how a natural set of chitinolytic enzymes may be built up. S. marcescens chitinase...
