Production of Escherichia coli-specific hybridomas by using gnotobiotic mice.
Monoclonal antibodies provide a rapid and specific means of direct detection of microorganisms in water and food samples. However, monoclonal antibodies specific for some bacteria are difficult to obtain; a good example of such a bacterium is Escherichia coli. Gnotobiotic BALB/c mice immunized with whole-cell preparations of heat-treated strains of E. coli and subjected to high-frequency antige...
متن کاملCopper import in Escherichia coli by the yersiniabactin metallophore system
Copper plays a dual role as a nutrient and a toxin during bacterial infections. While uropathogenic Escherichia coli (UPEC) strains can use the copper-binding metallophore yersiniabactin (Ybt) to resist copper toxicity, Ybt also converts bioavailable copper to Cu(II)-Ybt in low-copper conditions. Although E. coli have long been considered to lack a copper import pathway, we observed Ybt-mediate...
متن کاملImmunocompromise in gnotobiotic pigs induced by verotoxin-producing Escherichia coli (O111:NM).
A verotoxin-producing Escherichia coli serotype O111:NM strain (strain 10049; verotoxin 1 positive) persistently infected experimentally inoculated gnotobiotic pigs, causing attaching-effecting intestinal lesions and chronic diarrhea. Experiments were performed to determine whether persistent infection might be associated with immunocompromise of the host of this organism. Pigs inoculated with ...
متن کاملIntestinal Strangulation in Escherichia coli-Monocontaminated Gnotobiotic Rats.
The natural course of ischemic and hemorrhagic intestinal strangulation in previously germ-free rats individually monocontaminated with one of five separate strains of Escherichia coli was investigated. In addition, the effect of intraintestinal homologous heparinized blood upon the course of ischemic intestinal strangulation in E. coli-monocontaminated rats was studied. It was found that (i) E...
متن کاملInteraction between Escherichia coli and Shigella flexneri in the digestive tract of "gnotobiotic" mice.
When a strain of Shigella flexneri and then a strain of Escherichia coli were implanted at an interval of 1 day in the digestive tract of germfree mice, the S. flexneri was eliminated in 8 days. However, when S. flexneri was mono-associated with germfree mice in the absence of E. coli, a population of S. flexneri appeared which was resistant to the antagonistic effects of E. coli in vivo. The e...
