Curli loci of Shigella spp.
An unstable chromosomal element encoding multiple antibiotic resistance in Shigella flexneri serotype 2a was found to include sequences homologous to the csg genes encoding curli in Escherichia coli and Salmonella enterica serovar Typhimurium. As curli have been implicated in the virulence of serovar Typhimurium, we investigated the csg loci in all four species of Shigella. DNA sequencing and P...
متن کاملThe SHI-3 iron transport island of Shigella boydii 0-1392 carries the genes for aerobactin synthesis and transport.
In Shigella boydii 0-1392, genes encoding the synthesis and transport of the hydroxamate siderophore aerobactin are located within a 21-kb iron transport island between lysU and the pheU tRNA gene. DNA sequence analysis of the S. boydii 0-1392 island, designated SHI-3 for Shigella island 3, revealed a conserved aerobactin operon associated with a P4 prophage-like integrase gene and numerous ins...
متن کاملAntibiotic resistance of Shigella spp., Salmonella spp., and Yersinia spp. isolated in Quebec.
Salmonella spp., Shigella spp., and Yersinia spp. are important enteropathogenic bacteria. Antibiotic treatment is normally indicated for infections caused by Shigella spp. and only in the case of severe infections for Salmonella and Yersinia. Studies from a number of countries have reported the development of resistance of these bacteria to certain antibiotics. The new quinolones, such as cipr...
متن کاملEnteric bacteria Escherichia coli and Shigella spp
Gene clusters for biosynthesis of 24 of 34 basic O-antigen forms of Shigella spp. are identical or similar to those of the genetically closely related bacterium Escherichia coli. For 18 of these relatedness was confirmed chemically by elucidation of the O-antigen (O-polysaccharide) structures. In this work, structures of the six remaining O-antigens of E. coli O32, O53, O79, O105, O183 (all rel...
متن کاملOccurrence of integrons and resistance genes among sulphonamide-resistant Shigella spp. from Brazil.
OBJECTIVES To determine the occurrence of class 1 and 2 integrons and antimicrobial resistance genes among sulphonamide-resistant Shigella strains isolated in Brazil during 1999-2003. METHODS Sixty-two Shigella (Shigella flexneri, n = 47 and Shigella sonnei, n = 15) were tested against 21 antimicrobial agents. The presence of integrons classes 1 and 2 and antimicrobial resistance genes was in...
