Growth of typhoid and paratyphoid bacilli in intravenously infected mice.
The in vivo growth of Salmonella paratyphi A, S. paratyphi B, S. paratyphi C, and S. typhi, as well as of an S. typhi-typhimurium hybrid, was studied in three different strains of mice. S. paratyphi A and B and S. typhi demonstrated very little growth potential in any of the intravenously infected mice, even after as many as 20 serial mouse passages. It was noted, however, that small numbers of...
متن کاملInhibitory Action of Paratyphoid Bacilli on the Fermentation of Lactose by Bacillus Coli. I
Bacteria of the paratyphoid group may be divided into two classes according to the behavior of 4 day cultures in lactose bouillon after a second inoculation with certain types of Bacillus coli. One class includes all true hog-cholera bacilli, the other nearly all true paratyphoid and enteriditis types. Under the imposed conditions Bacillus coli produces the usual amount of gas in the presence o...
متن کاملA Study of Paratyphoid Bacilli Isolated from Cases of Hog-cholera
During the course of some experimental work on hog-cholera, paratyphoid bacilli were isolated from 16 per cent of the pigs. Culturally these organisms are the same as paratyphoid 18 isolated from man, while they show several differences from hog-cholera bacilli. In their slight pathogenic effect on rabbits they also differ from the hog-cholera bacillus. In their agglutination in sera produced b...
متن کاملThe Relation between Invasion of the Digestive Tract by Paratyphoid Bacilli and Disease
Hog cholera bacilli fed to mice disappear from the stomach within 24 hours, but remain and perhaps multiply in the ileum for at least several weeks. They promptly penetrate the mucosa and may be found in the spleen. Bacilli introduced subcutaneously quickly pass into the intestinal tract where they may be found for some weeks. Infected mice may harbor bacilli in the spleen for several months. M...
متن کاملA Group of Paratyphoid Bacilli from Animals Closely Resembling Those Found in Man
1. In addition to the paratyphoid bacilli already named there exists a group which occurs in a variety of animals and which culturally is the same as Bacillus schottmülleri. As a rule this group can be separated from the latter by the type of clumps formed when bouillon cultures are used as antigens, while other antigens and complement fixation tests have failed to differentiate it. Agglutinati...
