Isolation and identification of V. cholerae serogroups O1 and O139 can be
greatly enhanced when optimal laboratory media and techniques are employed.
The methods presented here are intended to be economical and to offer
laboratorians some flexibility in choice of protocol and media. Laboratories that
do not have sufficient resources to adopt the methods described in this chapter
should consider sending the specimens or isolates to other laboratory facilities
that routinely perform these procedures.
