| bactericidal activity against vibrio cholerae of chemical products used in lemon production in tucumán, argentina. | the present research was set up to verify whether the chemical products used in lemon production (from cultivation until packaging) have a bactericidal or a bacteriostatic ability against vibrio cholerae o1. the studied products were: copper oxychloride, benomil (a carbamate), active chlorine, sodium-o-phenylphenoate, guazatine (a polyamine mixture), imazalil (an imidazole) and lemon peel. the latter was studied with and without treatment using the above mentioned chemicals. different dilutions ... | 1997 | 9331994 |
| action against vibrio cholerae o1 tox+ of chemical products used in the lemon production. | tucuman is the first lemon exporting province in argentina and the fourth lemon exporter in the world. the present work was set up to study the survival of vibrio cholerae o1 tox+ after application of different chemical products used in the lemon production (from its cultivation until its packing). the following products were studied: copper oxychloride, benomil (a carbamate), active chlorine, sodium-o-phenylphenoate, guazatine (a polyamine mixture), imazalil (an imidazole) and fresh and dehydra ... | 1998 | 10932739 |
| genetic diversity of vibrio cholerae o1 in argentina and emergence of a new variant. | the genetic diversity of vibrio cholerae o1 strains from argentina was estimated by random amplified polymorphic dna (rapd) analysis and pulsed-field gel electrophoresis (pfge). twenty-nine isolates carrying the virulence genes ctxa, zot, ace, and tcpa appeared to represent a single clone by both typing methods; while 11 strains lacking these virulence genes exhibited several heterogeneous rapd and pfge patterns. among the last group, a set of isolates from the province tucumán showed a single r ... | 2003 | 12517837 |
| detection of viable and viable nonculturable vibrio cholerae o1 through cultures and immunofluorescence in the tucumán rivers, argentina. | vibrio cholerae has been sporadically isolated from rivers in tucumán, argentina, since the outbreak in 1991. the aim of this study was to determine the environmental reservoir of the bacterium in these rivers, assessing the presence of vibrio cholerae non-o1 and o1 (the latter both in its viable culturable and non culturable state) and its relationship to environmental physicochemical variables. 18 water samplings were collected in the salí river (in canal norte and banda) and the lules river b ... | 2007 | 17876456 |
