Survival of Shigella dysenteriae on fomites
Studies have shown that various objects, such as utensils, toys, and clothes, can serve as vehicles for transmission of Shigella spp. Shigellae can become viable but non-culturable (VBNC) when exposed to various environmental conditions as shown in earlier studies. The present study was carried out to detect VBNC Shigella dysenteriae type 1 on various fomites by direct viable counting, polymera...
متن کاملStudies on the nutritional requirements of bacteria. II. On the nutrition of Shigella dysenteriae.
The synthetic medium for Shigella dysenteriae which has hitherto been known contains many amino acids and also niacin-amide, although the necessity of which remains obscure (5, 11,12) . We have been examining the process of the evolution of the bacterial nutrition (or the retroevolution), especially about the nitrogen source. It is the purpose of this paper to report the nutritional nitrogen so...
متن کاملThe Specificity of the Agglutinin Reaction for Shigella dysenteriae: II. Agglutinin Absorption Relationships between Shigella dysenteriae and Escherichia coli.
In a previous communication (Mackie, 1938) we have reported observations upon the Shigella dysenteriae agglutinin curves in a group of patients presenting the intestinal pathology of chronic bacillary dysentery and bacteriologic or serologic evdence of infection by these organisms. Fluctuation of the titre curves in individual patients, the common finding of higher titres in the culture-negativ...
متن کاملStudies on lysogenesis. II. The effect of temperature on the lysogenization of Shigella dysenteriae with phage P1.
Sensitive bacteria, when infected with a temperate phage, either lyse or become lysogenic. With the temperate phage Pl and its host Shigella dysenteriae, the outcome of infection is affected strikingly by temperature. The discovery of this temperature effect has allowed us to study some features of the lysogenization process; these will be described in this paper. The definitions of certain ter...
