| molecular epidemiology of shigella infections: plasmid profiles, serotype correlation, and restriction endonuclease analysis. | plasmid isolation was used to refine the epidemiologic analysis for 168 shigellosis cases in pima county, ariz. plasmids of less than 20 kb were used for comparison of plasmid profiles. plasmid patterns for each species were distinct. a total of 57 of 74 (77%) shigella flexneri strains could be placed into seven plasmid patterns, 70 of 79 (89%) shigella sonnei strains could be placed into seven patterns, 12 shigella boydii strains could be placed into six patterns, and each of 3 shigella dysente ... | 1991 | 1847148 |

| current status of immunofluorescence techniques for rapid detection of shigellae in fecal specimens. | polyvalent shigella conjugates were prepared for shigella groups a, b, c, and d. after preliminary testing with pure cultures of both homologous and heterologous organisms, these reagents were used in three evaluation studies. fecal specimens from patients hospitalized with diarrhea, from children involved in an institutional outbreak of dysentery due to s. sonnei, and from patients with diarrhea in arizona were screened by fluorescent-antibody (fa) tests and were cultured. specimens were examin ... | 1965 | 14339269 |
