SA, L.L.C.; VALE, E.R.V.; GARZA, D.R.  and  VICENTE, A.C.P.. Vibrio cholerae O1 from superficial water of the Tucunduba Stream, Brazilian Amazon. Braz. J. Microbiol. [online]. 2012, vol.43, n.2, pp. 635-638. ISSN 1517-8382.  http://dx.doi.org/10.1590/S1517-83822012000200027.

Isolation and genetic characterization of an environmental Vibrio cholerae O1 from the Amazon is reported. This strain lacks two major virulence factors - CTX and TCP - but carries other genes related to virulence. Genetic similarity with epidemic strains is evaluated and the importance of V. cholerae surveillance in the Amazon is emphasized.
