| chronic vulvovaginitis in children due to shigella flexneri. | although previous reports have implicated shigella flexneri in resistant or chronic cases of vulvovaginitis in children, no authors have described the clinical findings of this condition. the report presents four cases of persistent vulvovaginitis in prepubertal indian girls from different reservation communities in arizona. s. flexneri was isolated in pure culture from the vaginal discharge of each patient. all four cases were characterized by a prolonged vaginitis with a bloody, purulent disc ... | 1975 | 1098002 |
| 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 |
| the epidemiology of s. sonnei and s. flexneri in pima county, arizona: an exploratory study. | investigation of 189 cases of shigellosis reported to the pima county, arizona health department in 1986 revealed that 23 per cent of cases could be attributed to travel to mexico, and 10 per cent to day care attendees and their household contacts. no source of infection or high-risk activity could be demonstrated for 43 per cent of the cases. households in which s. flexneri occurred were more likely to be characterized by crowded living situations and to have no known source of infection. | 1988 | 3044149 |
| enteric bacterial growth rates in river water. | enteric bacteria, including stocked strains of pathogenic species and organisms naturally present in the stream, were capable of growth in a chemostat with autoclaved river water taken 750 m below a sewage outfall. maximal specific growth rates for all organisms occurred at 30 c, whereas culture generation times ranged between 33.3 and 116 hr. of the six laboratory strains of enteric species used, escherichia coli and enterobacter aerogenes grew at generation times of 34.5 and 33.3 hr, respectiv ... | 1972 | 4561100 |

| high frequency of hla-b27 and reiter's syndrome in navajo indians. | eighteen cases of reiter's syndrome were found in a population of approximately 6,000 navajo indians. the phenotype frequency of hla-b27 in this population was found to be 36%. the area in which these people live is endemic for shigellosis, shigella flexneri being the most common species isolated. presumably the high frequency of hla-b27 and shigella infections account for the high incidence and prevalence of reiter's syndrome in this population. | 1980 | 7205829 |
