| [molecular epidemiological characteristics of salmonella typhi strains isolated in china. i. analysis of salmonella typhi strains isolated in china by multilocus enzyme electrophoresis]. | multilocus enzyme analysis by polyacrylamide gel electrophoresis (page) was used to analyse 335 isolates of s. typhi from several provinces where high morbidity of typhoid fever was observed in recent years. we analysed 7 metabolic enzymes encoded by chromosome. the results showed that all the enzyme loci were polymorphic. the average alleles per locus was 7.4 (2-19): the mean genetic diversity per locus was 0.498 (0.198 0.883). there were 147 distinctive electrophoretic types (ets) in 335 isola ... | 1994 | 7834706 |
