Hybridization between Escherichia coli and Shigella.
Genetic recombination by mating has been demonstrated among a variety of strains classified as Escherichia coli (Lederberg and Tatum, 1946; Cavalli et al., 1953). The possibility of genetic transfers among bacteria currently classified in different species or genera has been proved by transformation and transduction experiments (Lederberg and Edwards, 1953; Schaeffer and Ritz, 1955; Lennox, 195...

متن کاملWidespread antibiotic resistance of diarrheagenic Escherichia coli and Shigella species
BACKGROUND Antibiotic resistance of enteric pathogens particularly Shigella species, is a critical world-wide problem and monitoring their resistant pattern is essential, because the choice of antibiotics is absolutely dependent on regional antibiotic susceptibility patterns. During summer 2013, an unusual increase in number of diarrheal diseases was noticed in Isfahan, a central province of Ir...
متن کاملRestriction in genetic crosses between Escherichia coli and Shigella flexneri.
Shigella flexneri restricts Escherichia coli deoxyribonucleic acid (DNA) and can modify phage DNA so that it is restricted in E. coli.
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...
