| molecular epidemiology of non-o1 vibrio cholerae and vibrio mimicus in the u.s. gulf coast region. | ten toxigenic vibrio cholerae non-o1 and v. mimicus strains isolated from clinical and environmental sources in the u.s. gulf coast region were examined for genetic relatedness. restriction digest patterns of chromosomal dna and southern blot analysis with a cholera toxin gene probe revealed that the strains exhibited greater genetic divergence than the highly conserved v. cholerae o1 strains isolated from clinical and sewage samples in this region. | 1986 | 3007571 |
| 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 |
| a case of cholera in texas, 1973. | the first naturally acquired case of cholera reported in the united states since 1911 occurred in a 51-year-old resident of port lavaca, texas. extensive epidemiologic investigation of the patient's contacts and environment did not identify a cholera carrier of elucidate a pathway of transmission, but several avenues of investigation suggested possible means by which the patient may have acquired his infection. no secondary spread resulted from this case, and its occurrence did not endanger the ... | 1974 | 4447110 |
| isolation of nontoxigenic vibrio cholerae o group 1 from a patient with severe gastrointestinal disease. | a nontoxigenic strain of vibrio cholerae o group 1 was isolated in florida from the stool of a patient with severe diarrhea. the strain had the same hemolytic and unique phage-sensitivity pattern as all toxigenic isolates from recent cases of cholera in texas and louisiana. identical strains were transiently isolated from sewerage systems in two other florida communities, suggesting that multiple human infections had occurred. this is the first indication that v. cholerae o1 strains which do not ... | 1984 | 6199370 |
| molecular epidemiological studies of united states gulf coast vibrio cholerae strains: integration site of mutator vibriophage vca-3. | environmental and clinical vibrio cholerae o-1 strains isolated from the u.s. gulf coast region were found to be lysogenic for a vibriophage which we have designated vca-3. comparison of vca-3 with the previously described vibriophages vca-1 and vca-2 has shown that vca-1 and vca-3 are homoimmune, have extensive sequence homology, but have markedly different restriction endonuclease digestion patterns. vca-3 was found to randomly integrate into the v. cholerae rv79 chromosome and to introduce st ... | 1983 | 6618665 |
| cholera on a gulf coast oil rig - texas. | | 1981 | 6796815 |
| cholera on a gulf coast oil rig. | a single case of severe diarrhea on a floating texas oil rig was followed two days later by what proved to be the largest outbreak of cholera in the united states in over a century. after isolation of toxigenic vibrio cholerae el tor inaba of the typical united states phage type from the index patient's stool, the ensuing investigation detected 14 additional cases of cholera and one asymptomatic infection serologically. infection was associated with eating rice on the oil rig on a particular day ... | 1983 | 6877323 |
| cholera on the texas gulf coast. | cholera is being increasingly recognized in the gulf coast region. this report describes two cholera cases of classic clinical presentation. both cases were caused by toxigenic vibrio cholerae, one of an 01 serotype and one of a non-01 serotype. vibrio cholerae was also isolated from the home environments of both patients. these findings indicate that cholera continues to be detected on the gulf coast, that non-01 v cholerae infections may be clinically indistinguishable from v cholerae 01 infec ... | 1982 | 7062464 |
| incidence of vibrio species associated with blue crabs (callinectes sapidus) collected from galveston bay, texas. | bacteria were readily isolated from the hemolymph of a majority (88%) of the blue crabs collected from galveston bay, texas. the hemolymph of most crabs contained moderate (greater than 10(3) bacteria/ml) to heavy (greater than (10(5) bacteria/ml) infections. large variances were observed in the bacterial number associated with individual crabs, but no significant difference was observed between the mean bacterial levels in the hemolymph of crabs collected during different seasons of the samplin ... | 1982 | 7103475 |
| molecular epidemiology of vibrio cholerae in the u.s. gulf coast. | enterotoxigenic strains of vibrio cholerae o-1, biotype el tor, isolated from a case of cholera in texas in 1973, an outbreak of cholera in louisiana in 1978, and louisiana sewage samples in 1980 and 1981 were analyzed for their genetic similarities. chromosomal dna was isolated from each strain, digested with restriction endonuclease, and analyzed by the southern blot technique. a radioactive probe consisting of escherichia coli heat-labile enterotoxin dna detected cholera toxin gene sequences ... | 1982 | 7107852 |
| cholera--a possible endemic focus in the united states. | in september and october 1978, after a case of cholera had been discovered in southwestern louisiana, 10 more vibrio cholerae o-group 1 infections were detected in four additional clusters. all 11 infected persons had recently eaten cooked crabs from five widely separated sites in the coastal marsh, and a matched-triplet case-control study showed a significant relation between cholera and eating such crabs (p = 0.007). v. cholerae o1 was isolated from estuarine water, from fresh shrimp, from a l ... | 1980 | 7350497 |
| 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 |
| pulmonary cholera due to infection with a non-o1 vibrio cholerae strain. | we present 2 cases of primary pulmonary non-o1 vibrio cholerae infection. we believe that these are the first documented cases of primary pulmonary infection due to this organism from a freshwater source. | 2006 | 16954301 |
| freshwater non-o1 vibrio cholerae infection. | it is not appreciated by most physicians that vibrio infections can be acquired from freshwater exposure. a case of non-o1 vibrio cholerae urinary tract infection associated with freshwater exposure is reported. the potential for vibrios to grow in brachish water and for summer heat to cause evaporation leading to relative increased salinity in freshwater bodies and the broad geographic range of these occurrences to include north american and both eastern and western europe is noted. a literatur ... | 2010 | 20818301 |
| vibriosis, not cholera: toxigenic vibrio cholerae non-o1, non-o139 infections in the united states, 1984-2014. | toxigenic strains of vibrio cholerae serogroups o1 and o139 have caused cholera epidemics, but other serogroups - such as o75 or o141 - can also produce cholera toxin and cause severe watery diarrhoea similar to cholera. we describe 31 years of surveillance for toxigenic non-o1, non-o139 infections in the united states and map these infections to the state where the exposure probably originated. while serogroups o75 and o141 are closely related pathogens, they differ in how and where they infect ... | 2016 | 27510301 |
