Clonal relationships among Shigella serotypes suggested by cryptic flagellin gene polymorphism.
The presence of cryptic fliC alleles in the genomes of 120 strains representative of the four Shigella species was investigated. One fragment was obtained by PCR amplification of fliC, with a size varying from 1.2 to 3.2 kbp, depending on the species or serotype. After digestion with endonuclease HhaI, the number of fragments in patterns varied from three to nine, with sizes of between 115 and ...
متن کاملanalysis of clonal relationships among shigella spp. isolated from children with shigellosis in ahvaz, iran
shigellosis is one of the important gastrointestinal bacterial infections, particularly among children of developing countries such as iran. antibiotic susceptibility pattern and genetic typing for epidemiological purposes are of significant issues in shigella infectious control. the aim of this study was to investigate the antibiotic susceptibility and genetic relationship among shigella strai...
متن کاملStrategy for cross-protection among Shigella flexneri serotypes.
Based upon the lipopolysaccharide (LPS) structure and antigenicity of Shigella group B, a strategy for broad cross-protection against 14 Shigella flexneri serotypes was designed. This strategy involves the use of two S. flexneri serotypes (2a and 3a), which together bear the all of the major antigenic group factors of this group. The novel attenuated strains used in these studies were S. flexne...
متن کاملShigella boydii serotypes in Egypt.
While Shigella boydii serotypes have been reported on numerous occasions from many parts of the world (Weil and Saphra, 1953), they rarely have comprised more than a small proportion of the total number of Shigella found, and knowledge of their distribution, cultural characteristics, immunological relationships and pathogenicity is incomplete in some respects. This is particularly true of the m...
متن کاملAnalysis of HL and O serotypes of Campylobacter strains by the flagellin gene typing system.
We recently developed a molecular typing system for Campylobacter jejuni and Campylobacter coli based on restriction fragment length polymorphism analysis of the flagellin gene,flaA (I.Nachamkin, K. Bohachick, and C.M. Patton, J. Clin. Microbiol. 31:1531-1536, 1993). We extended the typing system to 83 flagellin types (designated flaA-1,flaA-2, etc.) on the basis of analysis of 404 isolates of ...
