| [isolation of vibrio strains in french coastal waters and infection with vibrio cholerae non-o1/non-o139]. | although the incidence in france of v. cholerae non-o1/non-o139 infection in man has increased since 1996, it remains low (7 cases in 1999). after the death in 1994 of an immunodepressed patient presenting a skin lesion showing superinfection by a strain of non-o1/non-o139 v. cholerae following exposure to seawater, we examined 22 samples of sea-water collected from 20 french coastal areas (mediterranean coast). | 2001 | 11346901 |
| evolutionary and functional analyses of variants of the toxin-coregulated pilus protein tcpa from toxigenic vibrio cholerae non-o1/non-o139 serogroup isolates. | the toxin-coregulated pilus (tcp) is a critical determinant of the pathogenicity of vibrio cholerae. this bundle-forming pilus is an essential intestinal colonization factor and also serves as a receptor for ctxphi, the filamentous phage that encodes cholera toxin (ct). tcp is a polymer of repeating subunits of the major pilin protein tcpa and tcpa is found within the vibrio pathogenicity island (vpi). in this study genetic variation at the tcpa locus in toxigenic isolates of v. cholerae was inv ... | 2002 | 12055286 |
| distribution of virulence markers in clinical and environmental vibrio cholerae non-o1/non-o139 strains isolated in brazil from 1991 to 2000. | one hundred seventy nine vibrio cholerae non-o1/non-o139 strains from clinical and different environmental sources isolated in brazil from 1991 to 2000 were serogrouped and screened for the presence of four different virulence factors. the random amplification of polymorphic dna (rapd) technique was used to evaluate the genetic relatedness among strains. fifty-four different serogroups were identified and v. cholerae o26 was the most common (7.8%). pcr analysis for three genes (ctxa, zot, ace) l ... | 2006 | 16699625 |
| [aeromonas associated with an acute diarrhea outbreak in são bento do una, pernambuco]. | an acute diarrhea outbreak, with 2170 cases, was described during january to july, 2004, in são bento do una, pernambuco. 582 stools were examined and an enteric pathogen was recovered in 25% (145 patients). aeromonas species were the most frequent (114-19.5%) and the main isolates were aeromonas caviae (57-9.8%), aeromonas veronii biovar sobria (23-3.9%), aeromonas veronii biovar veronii (15-2.6%) and other species (19-3.2%). the other isolated enteropathogens were vibrio cholerae o1-ogawa toxi ... | 2006 | 16699653 |
| [molecular-epidemiological characteristic and possible origin of vibrio cholerae non o1/non o139 with complete and limited set of virulence genes]. | study of molecular-epidemiological characteristics of vibrio cholerae non o1/non o139 serogroup with complete and limited set of virulence genes was performed. differences of their genes composition as compared to these of o1 serogroup (classic and el tor biovars) were revealed, which points to their origin from avirulent environmental cholera vibrios. | 2007 | 18038543 |
| rapid growth of planktonic vibrio cholerae non-o1/non-o139 strains in a large alkaline lake in austria: dependence on temperature and dissolved organic carbon quality. | vibrio cholerae non-o1/non-o139 strains have caused several cases of ear, wound, and blood infections, including one lethal case of septicemia in austria, during recent years. all of these cases had a history of local recreational activities in the large eastern austrian lake neusiedler see. thus, a monitoring program was started to investigate the prevalence of v. cholerae strains in the lake over several years. genetic analyses of isolated strains revealed the presence of a variety of pathogen ... | 2008 | 18245230 |
| identification and characterization of a novel type iii secretion system in trh-positive vibrio parahaemolyticus strain th3996 reveal genetic lineage and diversity of pathogenic machinery beyond the species level. | vibrio parahaemolyticus is a bacterial pathogen causative of food-borne gastroenteritis. whole-genome sequencing of v. parahaemolyticus strain rimd2210633, which exhibits kanagawa phenomenon (kp), revealed the presence of two sets of the genes for the type iii secretion system (t3ss) on chromosomes 1 and 2, t3ss1 and t3ss2, respectively. although t3ss2 of the rimd2210633 strain is thought to be involved in human pathogenicity, i.e., enterotoxicity, the genes for t3ss2 have not been found in trh- ... | 2009 | 19075025 |
| multiresistant vibrio cholerae non-o1/non-o139 from waters in south india: resistance patterns and virulence-associated gene profiles. | from different aquatic locations in alleppey district, kerala, south india a number (n = 36) of multiresistant non-o1, non-o139 v. cholerae strains were isolated. water samples were filtered through 0.22 mum membrane filters, enriched in alkaline peptone water and plated onto thiosulfate-citrate-bile salts-sucrose (tcbs) agar. the isolates were resistance to cefotaxime (50%), nalidixic acid (44.4%), streptomycin and tetracycline (41.6%), trimethoprim (38.8%), co-trimoxazole (33.3%), furazolidone ... | 2009 | 19810041 |

| an acute gastroenteritis outbreak of vibrio parahaemolyticus o4:k55 in nursing college, thailand. | a cluster of acute gastroenteritis among nursing students was noticed on 13th september 2005. between 13th and 17th september 2005, a retrospective cohort study was then conducted to identify the most likely cause of gastroenteritis at a nursing college in bangkok, thailand. self-administered questionnaires, interviews, environmental investigations, and rectal swabs from all participants were carried out. in the investigation, 98.9% female nursing students were investigated and had completed the ... | 2010 | 20962724 |
| interaction of vibrio cholerae non-o1/non-o139 with copepods, cladocerans and competing bacteria in the large alkaline lake neusiedler see, austria. | vibrio cholerae is a human pathogen and natural inhabitant of aquatic environments. serogroups o1/o139 have been associated with epidemic cholera, while non-o1/non-o139 serogroups usually cause human disease other than classical cholera. v. cholerae non-o1/non-o139 from the neusiedler see, a large central european lake, have caused ear and wound infections, including one case of fatal septicaemia. recent investigations demonstrated rapid planktonic growth of v. cholerae non-o1/non-o139 and corre ... | 2010 | 21049271 |
