Characterization of Shigella dysenteriae serotypes 11, 12, and 13.
We conducted serologic and biochemical studies on strains of three provisional Shigella serotypes. Included were 19 strains of serotype 3873-50 from three countries (1 from Mexico, 1 from Netherlands Antilles, and 17 from the United States), 13 strains of serotype 3341-55 from three countries (1 from Canada, 1 from Bulgaria, and 11 from the United States), and 19 strains of serotype 19809-73 fr...
متن کاملMolecular characterization of the SHV-11 beta-lactamase of Shigella dysenteriae.
A beta-lactamase with an M(r) of 29,000 and a pI of 7.6 was partially purified from a clinical isolate of Shigella dysenteriae. The bla gene encoded the SHV-11 enzyme carrying the substitution Leu-->Gln at position 35 and was linked to a strong promoter. This variant, unlike the prototype SHV-1 enzyme, hydrolyzed oxacillin, cloxacillin, and oxyiminocephalosporins such as cefotaxime.
متن کاملMolecular and phenotypic characterization of potentially new Shigella dysenteriae serotype.
From September 1997 to November 1998, the French National Center for Salmonella and Shigella received 22 Shigella isolates recovered from 22 different patients suffering from dysentery. None of these isolates reacted with any of the antisera used to identify established Shigella serotypes, but all of them agglutinated in the presence of antisera to a previously described potentially new Shigell...
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...
