Avian salmonellosis: detection and characterization of serologic response to major serogroup infections

Serologic procedures for the diagnosis of salmonella infections in poultry flocks have evolved from laboratory and field macrotest procedures to recently reported microtests with savings of cost, time, and space. Microtest methods when used as the sensitive and specific microantiglobulin test provide a means of effectively detecting birds exposed to salmonella serogroup B, C, and D infections. Progress will be made in the better detection and control salmonella infections in poultry when attention is given to all major salmonella serogroups rather than a few selected serotypes.
