Insights into lantibiotic immunity provided by
22 The lantibiotic lacticin 3147 has been the focus of much research due to its broad spectrum of 23 activity against many microbial targets, including drug resistant pathogens. In order to protect 24 itself, a lacticin 3147 producer must possess a cognate immunity mechanism. Lacticin 3147 25 immunity is provided by an ABC transporter, LtnFE, and a dedicated immunity protein, LtnI, 26 both of w...
متن کاملEnteric Bacteria
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 کاملInfrared spectrophotometry of enteric bacteria.
Infrared spectrophotometry is rapidly assuming an important place in the biological sciences. Its value derives from the fact that each organic compound has a characteristic and distinct infrared spectrum that can be used to identify it (Randall et al., 1949). The biologist working with cells or tissues is confronted by a highly complex mixture of substances. The infrared spectrum of a cell, th...
متن کاملEnteric Bacteria in Aquatic Ecosystems
were prepared from two enteric bacterial species, Escherichia coli and Enterococcus faecalis. Counts of CFU of NSB and RSB and total numbers of RSB and FLB were monitored over time, both in the presence and in the absence of natural microbiota. In the presence of natural microbiota, no differences were observed between CFU counts of NSB and RSB, but RSB total numbers were 1 to 4 orders of magni...
