A medium for Shigella dysenteriae under anaerobic conditions.
enzyme preparations cannot be aged and reactivated in a convincing way (Williams and McIntyre, J. Biol. Chem., 217, 467, 1955). The action of certain of these factors such as adenosine and glucose is now regarded as a membrane effect (Trudinger, Australian J. Exptl. Biol. Med. Sci., 33, 67, 1955; and Smith and Lichstein, Proc. Soc. Exptl. Biol. Med., 86, 586, 1954). The mode of action of biotin...
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 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 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...
