An anaerogenic strain of Bacterium paratyphosum C
Published online by Cambridge University Press: 15 May 2009
Extract
1. The existence of an anaerogenic strain of Bact. paratyphosum C is recorded in Egypt.
2. It was isolated in August 1937, together with an aerogenic strain, from the urine of a patient suffering from enteric fever.
3. Biologically the anaerogenic strain was identical with the aerogenic except that it did not produce gas from any “sugar”.
4. The anaerogenic strain retained its inability to produce gas from “sugars” for the three years during which tests were carried out, subculturing on various fluid media containing different sugars failing to cause any gas production.
5. Serologically there was no indication of any antigenic difference between the anaerogenic and the aerogenic strains.
6. The anaerogenic strain contained the Vi antigen and retained it for three years when kept at room temperature.
