| day care-related outbreaks of rhamnose-negative shigella sonnei--six states, june 2001-march 2003. | during june 2001--march 2003, outbreaks of shigella sonnei infections were reported in delaware, maryland, new jersey, north carolina, south carolina, and virginia. five- to fortyfold increases in statewide shigellosis rates were observed during this period. these increases were attributed primarily to outbreaks in multiple day care settings that became prolonged and community wide. s. sonnei isolates from these states, as well as from new york city and philadelphia, were similar genetically by ... | 2004 | 14749615 |
| application of a geographic information system to the tracking and control of an outbreak of shigellosis. | a personal computer-based commercial geographic information system (gis) was applied to an outbreak of shigella sonnei infection at fort bragg, north carolina. we used a database consisting of demographic, temporal, and home-address information for all recognized cases of s. sonnei that occurred among health care beneficiaries from 23 may 1997 through 14 august 1997. we imported this database into the gis, which contained a digitized basemap of the local community. through simultaneous examinati ... | 2000 | 11017823 |

| a large outbreak of antibiotic-resistant shigellosis at a mass gathering. | in july 1987, a large outbreak of shigellosis occurred among attendees at a mass gathering in a national forest, the annual rainbow family gathering. sanitation in the campsite was poor, allowing widespread transmission of disease, probably by food, water, and person-to-person spread. the attack rate may have been greater than 50% among the estimated 12,700 attendees. the outbreak was caused by shigella sonnei, resistant to ampicillin, tetracycline, and trimethoprim-sulfamethoxazole; the organis ... | 1990 | 2230262 |
| novel dihydrofolate reductases isolated from epidemic strains of trimethoprim/sulfamethoxazole-resistant shigella sonnei. | two strains of trimethoprim-resistant shigella sonnei bearing r plasmids pbh600 and pbh700 each elaborated a dihydrofolate reductase (dhfr) and were moderately resistant to trimethoprim (minimum inhibitory concentrations, 128 and 256 micrograms/ml, respectively). neither plasmid hybridized to probes for dhfr types i, ii, or iii. the trimethoprim resistance genes from the r plasmids resided on a 1600-base pair (bp) psti fragment of pbh600 and an 1800-bp psti fragment of pbh700. isoelectric focusi ... | 1990 | 2197340 |
