Quantitative Analyses of Certain Enteric Bacteria and Bacterial Extracts: II. Discrimination of Sonic Extracts by Interfacial Densitometry of Precipitin Systems.
Bacterial extracts prepared by ultrasonic disruption were reacted with both narrow- and broad-spectrum reference (homologous) and cross-reacting (heterologous) precipitins produced in rabbits. Quantitation of the reaction was obtained by densitometry of the antigen-antibody interface. Comparisons were made of sonic extracts from various starting populations all equated to the same nitrogen conc...

Biochemical confirmation of salmonellae by conventional tube methods usually requires 2 to 3 days of incubation time preceded by preparation of tubed media and transfer of cultures. The principles of heavy inocula and increased substrate concentrations have been used by Sanders et al. (1) to speed up reaction times and thus reduce the time necessary in the laboratory for analysis. To characteri...
متن کاملGlycogen of enteric bacteria.
In the course of an investigation of the use of infrared spectrophotometry for bacterial identification (Stevenson and Bolduan, 1952; Levine et al., 1953b), it has been found that a characteristic set of absorption bands appears in the spectra of Enterobacteriaceae and other bacteria under certain cultural conditions. Since this set of bands is common to many organisms, it is important in ident...
متن کاملAnti-Bacterial Property and Cytotoxicity of Allium Sativum and Myrtus Communis Extracts against Nosocomial Bacterial Infections
Background: Microbial infections and the resistance to antibacterial drugs are on the rise, and scientists are in search of the safest and most effective approach to overcome them. Medicinal plants are potentially effective against many microorganisms. Therefore, this study was planned to examine the antibacterial properties and cytotoxicity of the extracts of Allium sativum and Myrtus communis...
