seroepidemiology of cholera in gulf coastal texas. | single serum samples from 559 volunteers from a texas gulf coast area were examined for vibriocidal antibody to vibrio cholerae o1 (biotype el tor, serotype inaba) by a microtiter method. elevated levels of vibriocidal antibody were present in 14% of the subjects. also, 6.8% of the subjects had elevated levels of antibody to the enterotoxin of v. cholerae o1 by the immunoglobulin g enzyme-linked immunosorbent assay. recent infection, defined on the basis of elevations in both vibriocidal and ant ... | 1988 | 3415232 |
persistence of cholera in the united states: isolation of vibrio cholerae o1 from a patient with diarrhea in maryland. | a case of cholera was identified in baltimore county, md., in october 1984. the vibrio cholerae o1 isolate from the patient was hemolytic, biotype el tor, serotype inaba, and was toxigenic by the y-1 adrenal cell assay; on southern blot analysis, the strain had a unique hindiii restriction site in the cholera toxin gene identical to that of other u.s. v. cholerae o1 isolates. two days before he became ill, the patient had eaten meat from crabs harvested along the texas coast. | 1986 | 3958151 |
clinical and laboratory features of an outbreak of vibrio cholerae o1 infections in the united states. | a point source outbreak of vibrio cholerae o1 el tor inaba infections occurred aboard an oil rig south of port arthur, texas, in september 1981. sixteen crew members had v. cholerae o1 infections as determined by serology or stool specimens; 15 were symptomatic. the high percentage of symptomatic infections was attributed in part to the ingestion of a large number of v. cholerae o1 organisms by susceptible individuals. symptoms included diarrheal stools (100%), weakness (60%), abdominal cramps ( ... | 1985 | 3979022 |
molecular evolution of the seventh-pandemic clone of vibrio cholerae and its relationship to other pandemic and epidemic v. cholerae isolates. | genetic variation and molecular evolution within the seventh-pandemic clone of vibrio cholerae o1 and its relationship to other v. cholerae isolates were examined by studying 58 clinical isolates that were epidemiologically unassociated and isolated from patients in different countries over 62 years (1931 to 1993). the sample consisted of 45 isolates from the seventh cholera pandemic (1961 to the present), 3 from the sixth pandemic, 3 from sporadic el tor outbreaks prior to the seventh pandemic, ... | 1994 | 7928989 |
