| studies on the enteropathogenic mechanism of non-o 1 vibrio cholerae isolated from the environment and fish in toyama prefecture. | enteropathogenic mechanisms of non-o 1 vibrio cholerae were investigated using strains from the environment and those from fish in toyama prefecture. none of the 93 non-o 1 v. cholerae strains produced a detectable level of choleratoxin-like-enterotoxin (ct-like-enterotoxin) in syncase medium, while 23 strains showed a distinct fluid accumulation in the rabbit ileal loop test (ril). these ril-positive strains neither produced ct-like-enterotoxin in vitro in the other four kinds of media which ar ... | 1984 | 6493071 |
| ecology of non-o 1 vibrio cholerae in toyama prefecture. | the ecology of non-o 1 vibrio cholerae and vibrio mimicus as causes of cholera-like diarrhea or seafood-associated gastroenteritis has been investigated in toyama prefecture since 1980. the relationship between biological or serological characteristics of the isolates and their enteropathogenicity is discussed. overall isolation rates from river water, sea water, and fish were 24.0, 59.5, and 33.7%, respectively, the isolation frequency being, in general, extremely high in the summer season, alt ... | 1984 | 6738382 |
| widespread circulation of echovirus type 13 demonstrated by increased seroprevalence in toyama, japan, between 2000 and 2003. | to confirm the magnitude of an echovirus type 13 (e13) outbreak in 2002 and to evaluate whether genetic and antigenic changes in e13 influenced the occurrence of the outbreak, we measured titers of neutralizing (nt) antibody against the toyama, 2002-240-sf, and prototype del carmen e13 strains among inhabitants of toyama before and after 2002. the rate of positivity for nt antibodies against both 2002-240-sf and del carmen in 2003 made a remarkable upturn in children 0 to 14 years old, compared ... | 2010 | 20335430 |
