The detection of Salmonella infection in calves by the fluorescent antibody test.
The fluorescent antibody test (FAT) was used for the direct detection of salmonellas in 182 lymph nodes from adult cattle and from calves submitted for autopsy or used for experimental purposes. Salmonellas were detected in 22 samples by the FAT and in 18 by culture examination. The predictive value of the FAT was 68% and it was concluded that the test could be used for the rapid presumptive diagnosis of bovine salmonellosis.
