| [bacteriological and virological studies on the cause of sporadic acute gastroenteritis in tama, tokyo (1991-1996)]. | between may 1991 and december 1996, bacteriological and virological investigations on the fecal samples from patient of infantile diarrhea (155 cases), or infectious gastroenteritis (1,409 cases) diagnosed with 9 medical institutions in tama of tokyo were carried out. of 1,564 samples, 722 (46.2%) were enteropathogen positive cases, and mixed infection was also observed in about 15% of the positive cases. among 13 different kinds of enteropathogens identified, the most prevalent one was pathogen ... | 1998 | 9695470 |
| distribution and significance of heterotrophic marine bacteria with antibacterial activity. | bacteria with antibacterial activity were isolated from seawater, sediments, phytoplankton, and zooplankton of suruga, sagami, and tokyo bays and from soft corals and sponges collected from the taiwan coast. of the 726 strains isolated, 37 showed antibacterial activity against either vibrio parahaemolyticus (atcc 17802) or staphylococcus aureus (p209). sediment harbored the lowest number of these forms of bacteria, and those from tokyo bay did not show any activity. attached isolates showed grea ... | 1987 | 3435149 |
| comparative study of the aerobic, heterotrophic bacterial flora of chesapeake bay and tokyo bay. | a comparative study of the bacterial flora of the water of chesapeake bay and tokyo bay was undertaken to assess similarities and differences between the autochthonous flora of the two geographical sites and to test the hypothesis that, given similarities in environmental parameters, similar bacterial populations will be found, despite extreme geographic distance between locations. a total of 195 aerobic, heterotrophic bacterial strains isolated from chesapeake bay and tokyo bay water were exami ... | 1979 | 453838 |
| desulfovibrio marinisediminis sp. nov., a novel sulfate-reducing bacterium isolated from coastal marine sediment via enrichment with casamino acids. | to obtain amino acid-utilizing sulfate reducers, enrichment culture was carried out with a medium containing casamino acids and sulfate and inoculated with coastal marine sediment from the eutrophic tokyo bay, japan. a sulfate reducer, designated strain c/l2(t), was isolated from the sulfide-producing enrichment culture after further enrichment with lactate and sulfate by means of the agar shake dilution method. cells of strain c/l2(t) were vibrio-shaped, gram-negative, motile rods (0.7-1.0 mum ... | 2008 | 18842870 |
| multiple-locus variable-number of tandem-repeats analysis distinguishes vibrio parahaemolyticus pandemic o3:k6 strains. | a specific serotype of vibrio parahaemolyticus, o3:k6, has recently been linked to epidemics of gastroenteritis in southeast asia, japan, and north america. these pandemic o3:k6 strains appear to have recently spread across continents from a single origin to reach global coverage, based on profiling of strains by several molecular typing methods. in this study, variable-number tandem repeats (vntr)-based fingerprinting was applied to clinical and environmental v. parahaemolyticus o3:k6 strains i ... | 2008 | 18258320 |
| evaluation of ecotoxicity and fate of methylated butyltins in sediments and seawater from tokyo bay, japan. | we analyzed the fate of organotins in seawater and sediments from tokyo bay, japan, by gas chromatography/inductively coupled plasma mass spectrometry. we also measured the toxicity of methylated butyltins by in vitro bioassays, the retinoid x receptor (rxr) activation method, and the marine luminescent bacterium vibrio fischeri. concentrations of tributyltin (tbt) and tributylmonomethyltin (tbmmt) in seawater were 0.0636 to 0.419 and 0.0050 to 0.108 ng sn/l and in sediment were 7.51 to 17.8 and ... | 2007 | 18020680 |
| [basic studies on vibrio vulnificus infection: isolation of v. vulnificus from sea water, sea mud, and oysters]. | to clarify the environmental distribution of vibrio vulnificus, sea water, sea mud, and oysters were examined at 13 sites, i.e. 4 sites in the tokyo bay (eastern japan) and 9 sites (5 sites for oysters) in tokushima prefecture (western japan). 1. v. vulnificus was isolated from 80 (54.8%) of the 146 samples of sea water examined. it was isolated from 19 (41.3%) of the 46 samples from western japan and 61 (61.0%) of the 100 samples from eastern japan. 2. it was isolated from 40 (40.8%) of the 98 ... | 2002 | 12212318 |
| [the trends of vibrio parahaemolyticus foodborne outbreaks in tokyo: 1989-2000]. | the total number of foodborne outbreaks due to vibrio parahaemolyticus in tokyo during the last 12 years between 1989 and 2000 were 710. the number of outbreaks in a year was 55 in 1989, 75 in 1990, and there was a gradual decrease to 24 outbreaks in 1993 which was the smallest number during those 12 years. after 1994, the number of outbreaks increased dramatically year by year until 1998 (107 outbreaks). then they had decreased slightly to 74 in 1999, 65 in 2000. the monthly incidence of v. par ... | 2001 | 11494566 |
| [sporadic diarrhea caused by vibrio cholerae non-o1 and characteristics of the isolates]. | in 1996, we examined five domestic and eight imported cases of sporadic diarrhea caused by vibrio cholerae non-o1 in tokyo. the domestic cases occurred during the summer, from june to september, while the imported cases were seen throughout the year. the major clinical symptoms of the patients were watery diarrhea (100%) with an average frequency of 5.5 times/day, abdominal pain (77%), vomiting (31%) and fever (15%). a total of 13 strains isolated from these 13 cases had the typical biochemical ... | 1997 | 9483880 |
