Chemical Detoxification of Flexner Dysentery Antigen: II. Studies of Accelerated Growth Rates.
A major problem which arises in work on the chemistry of bacteria is that of obtaining adequate amounts of organisms with the facilities of the ordinary research laboratory. For this purpose, in growing bacteria for chemical studies on Flexner dysentery organisms (Barnes, Dewey, Henry, and Lupfer, in press), a method was developed for obtaining large amounts of this organism rapidly, and in hig...
متن کاملChemical detoxification of Flexner dysentery antigen; a mouse test to measure toxicity relative to antigenicity.
The problem of developing a detoxified Flexner dysentery antigen for use in the armed forces during the recent war (Barnes, Dewey, Henry, and Lupfer, 1947; Barnes and Dewey, 1947) required a test by which the results of a given chemical or physical manipulation of the antigen could be evaluated with respect to both toxicity and protection. It was necessary to do this with such precision and def...
متن کاملThe Biochemical Target of Flexner Dysentery Somatic Antigen
The effect of various harmful substances on proteins of living cells and the response of the proteins to stimulus from such compounds are of interest in many biological problems, such as growth, immunity, disease processes, etc. The little-known stimulus and response phenomena in this field could be investigated if there were available some specific system composed of a purified protein as the ...
متن کاملA Small Epidemic of Flexner (?) Dysentery
To the Editor, The Indian Medical Gazette. Sir,?In some villages near Mandya in Mysore District, a few cases of dysentery were reported and the health officer in charge of the rural unit sent seven motions from patients suffering from the attack, and two water samples from wells that were reported to have caused dysentery after use, for bacteriological analysis. A relevant portion of this lette...
متن کاملDivisions of the so Called Flexner Group of Dysentery Bacilli
From these data it is seen that ill defined divisions of the so called Flexner group exist. The divisions do not appear to be sufficiently distinct to warrant the use of separate names. To avoid confusion all mannitol-fermenting dysentery bacilli should be called Bacillus dysenteriae Flexner and the subdivision noted. There are two methods for this division, one by the fermentation of carbohydr...
