Cross-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 ...

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...

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 fe...
