| distribution of vibrio cholerae virulence genes among different vibrio species isolated in sardinia, italy. | the members of the genus vibrio include harmless aquatic strains as well as strains capable of causing epidemics of cholera. diarrhoea caused by vibrio cholerae is attributed to cholerae enterotoxin (ct) codified by the ctx operon and regulated by a number of virulence genes such as toxt, toxr and toxs. fifty-two vibrio strains were isolated from different aquatic environments in and around sardinia and searched by pcr for the presence of ctxa, zot, ace, toxr, toxs, toxt, tcpa and vpi virulence ... | 2000 | 10747228 |
| hygiene and health risks associated with the consumption of edible lamellibranch molluscs. | edible lamellibranch molluscs are frequently the cause of very serious outbreaks of food poisoning. microbiological suitability for human consumption, according to ec reg. n. 1441/2007, is only based on two faecal bacteriological contamination parameters (escherichia coli and salmonella) and does not consider other microorganisms which are naturally present within the marine environment and are potentially pathogenic such as those belonging to the genus vibrio. in this study, a total of 540 samp ... | 2015 | 25744696 |
