You have to be real carefull on this one and I dont therefore think quick
and easy is a option. One shot diagnostics are something to beware of given
the various complexity and factors effecting accurate differentiation of
Salmonella species and C/F.
Quick and accurate is an option if you have the tech support and
accesability to PCR or Ribotyping facillities.
Being realliably informed and confindent would invovle full biochemical
screening ( a la API or some such kit or LIA in combination with TSIA)
together with serological screening to group or species level.
If you want more detailed help mail me.
