چکیده
In this paper, some evidence, exper imental or clinical, is presented on the fol lowing subjects : ( I ) The infectious power of a living, sensitized vaccine; (2 ) the absence of immuni ty in vaccinated rabbits to direct gall bladder infect ions; (3 ) the relative pathogenicity, virulence, and toxic i ty of the strain used in the A r m y vaccine; (4 ) local vaccine reactions a f te r typhoid fever and af te r immunizat ion; and (5) skin reactions as an index of immunity.

Observations on Antityphoid Vaccination
1. Metchnikoff and Besredka's living sensitized vaccine produces a typhoid cholecystitis when injected directly into the gall bladder of rabbits. It is therefore infectious. 2. Rabbits cannot be successfully immunized with this vaccine against direct gall bladder infections. Accordingly, rabbits cannot be used to test immunity in this way. 3. The strain used in the Army vaccine is pathogenic, r...
متن کاملAntityphoid and radical scavenging properties of the methanol extracts and compounds from the aerial part of Paullinia pinnata
Paullinia pinnata Linn (Sapindaceae) is a medicinal plant, locally used in the West Region of Cameroon for the treatment of typhoid fever. This work was designed to evaluate the antityphoid and antioxidant activities of the extracts and compounds of P. pinnata. The methanol extracts of the leaves and stems were tested for antityphoid and antioxidant activities. Compounds were isolated, and thei...
متن کامل"Straight back to barbarism": antityphoid inoculation and the Great War, 1914.
On 27 August 1914, just three weeks after the outbreak of the Great War, Sir William Osler, Regius Professor of Medicine at Oxford University, wrote a letter to the Times, in which he urged the necessity of compulsorily vaccinating British troops against typhoid. "In war," he pressed, "the microbe kills more than the bullet," and he reminded his readers that more men had died of dysentery and t...
متن کاملCross-reactions of Antityphoid and Antiparatyphoid B Horse Sera with Various Polysaccharides
A study was made of cross-reactions of synthetic polyglucose and of numerous plant and bacterial gums in an antityphoid and an antiparatyphoid B horse serum. The observed differences permit conclusions to be drawn regarding certain of the linkages likely to be found in the fine structures of each of the corresponding Salmonella polysaccharides:- 1. Cross-reactions of the antityphoid serum with ...
متن کاملA Study of the Dissociation of the Rawlins Strain of Bacterium Typhosum with Special Reference to Its Use in the Production of Anti-typhoid Vaccine
A study of the subcultures of the Rawlins strain of Bacterium typhosum used by twelve different laboratories for vaccine production showed that they all differed from recently isolated smooth strains in cultural characteristics, virulence and protective efficiency. Eleven of these Rawlins cultures gave both the flagellar and the somatic type of agglutination in anti-smooth rabbit serum, and the...
