Biological properties of Shigella flexneri 2A toxin and its serological relationship to Shigella dysenteriae 1 toxin.
A toxin extracted from heat-inactivated, alkaline-treated Shigella flexneri 2a showed biological properties similar to those of Shigella dysenteria 1 toxin. The S, flexneri 2a toxin was lethal to mice, enterotoxic for ileal loops of rabbits, and cytotoxic for HeLa cells. A serological relationship between S. flexneri 2a and S. dysenteriae 1 toxin was shown with cross neutralization tests.
متن کاملSurvival 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 کاملShigella dysenteriae Serotype 1, Kolkata, India
Since July 2002, bacteriologically confirmed shigellosis cases have increased, and multidrug-resistant Shigella dysenteriae serotype 1 strains have reemerged in patients hospitalized with diarrhea in Kolkata, India. The isolated strains of S. dysenteriae 1 showed resistance to chloramphenicol (80%), ampicillin (100%), tetracycline (100%), co-trimoxazole (100%), nalidixic acid (100%), norfloxaci...
متن کاملSibling sRNA RyfA1 Influences Shigella dysenteriae Pathogenesis
Small regulatory RNAs (sRNAs) of Shigella dysenteriae and other pathogens are vital for the regulation of virulence-associated genes and processes. Here, we characterize RyfA1, one member of a sibling pair of sRNAs produced by S. dysenteriae. Unlike its nearly identical sibling molecule, RyfA2, predicted to be encoded almost exclusively by non-pathogenic species, the presence of a gene encoding...
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...
