Characterization of free-living and plankton-associated Vibrio cholerae strains isolated from environmental samples collected in Brazilian harbor areas.

Harbor areas	V. cholerae
	Free-living (F) or plankton-associated (A)	Serogroup	Genotype
Belém	F	O1	ctxA−/tcpA−
		Non-O1	ctxA+/tcpA+
Recife	F	O1	ctxA+/tcpA+, ctxA+/tcpA−
		Non-O1	ctxA+/tcpA+, ctxA+/tcpA−, ctxA−/tcpA+
	A	Non-O1	ctxA+/tcpA+, ctxA+/tcpA−, ctxA−/tcpA+
Itaguaí	F	Non-O1	ctxA−/tcpA−
Santos	F	O1	ctxA+/tcpA−
		Non-O1	ctxA+/tcpA+, ctxA+/tcpA−
	A	O1	ctxA+/tcpA+
		Non-O1	ctxA+/tcpA+, ctxA+/tcpA−
Paranaguá	F	O1	ctxA+/tcpA+
		Non-O1	ctxA+/tcpA+, ctxA+/tcpA−
	A	Non-O1	ctxA−/tcpA−

Genotypes ctxA and tcpA are genes codifying for cholera toxin and toxin co-regulated pilus, respectively.
