Pathogenesis of Experimental Cholera
Choleragen, a diarrheagenic protein enterotoxin elaborated by Vibrio cholerae, has been isolated from the supernate of fermenter cultures by steps involving ammonium sulfate precipitation, DEAE cellulose, Sephadex G-75, and Agarose A-5m chromatography. The resulting product appears to be pure according to immunoelectrophoretic, disc electrophoretic, ultracentrifugal, and immunologic criteria. S...
متن کاملNON - SPECIFIC RESISTANCE TO EXPERIMENTAL CHOLERA Materials
Thus, Bohnhoff et al. (1) made mice more susceptible to oral challenge with a streptomycin-resistant strain of Salmonella enteritidis by pretreatment with streptomycin. They concluded that this increase in susceptibility resulted from a disturbance of the normal intestinal microflora. Using a similar method, Freter (2-4) was able to induce an asymptomatie carrier state in guinea pigs and mice w...
متن کاملExperimental distribution of entanglement with separable carriers.
The key requirement for quantum networking is the distribution of entanglement between nodes. Surprisingly, entanglement can be generated across a network without direct transfer-or communication-of entanglement. In contrast to information gain, which cannot exceed the communicated information, the entanglement gain is bounded by the communicated quantum discord, a more general measure of quant...
متن کاملNon-specific Resistance to Experimental Cholera in Embryonated Eggs
It has been confirmed that 11- and 13-day-old chick embryos are susceptible to lethal infection with minute inocula of V. cholerae, while 15-day-old embryos are relatively resistant. Twenty strains of E. coli were found to vary in their capacity to kill chick embryos, without relationship to their human enteropathogenicity. Prior infection of 13-day-old embryonated eggs with E. coli strains sel...
متن کاملFlagella-induced immunity against experimental cholera in adult rabbits.
The adult rabbit ligated ileal loop model was used to evaluate the prophylactic potential of a crude flagellar (CF) vaccine produced from the classical. Inaba strain CA401. A greater than 1,000-fold increase in the challenge inoculum was required to induce an intestinal fluid response in actively immunized adult rabbits equivalent to that produced in unimmunized animals. Similar protection was ...
