title: Identification of Brucella abortus in formalin-fixed, paraffin-embedded tissues of cows, goats, and mice with an avidin-biotin-peroxidase complex immunoenzymatic staining technique.
abstract: An avidin-biotin-peroxidase complex immunoenzymatic staining technique was evaluated for light microscopic detection of Brucella organisms in formalin-fixed, paraffin-embedded tissues. Tissues from cows, goats, and mice inoculated with B abortus strain 2308 were examined, using rabbit antiserum to Brucella cell surface protein as primary antibody. Stained organisms were identified histologically in tissue sections containing B abortus, as detected by bacteriologic examination of duplicate nonprocessed tissue samples. Bacillus sp, Corynebacterium pyogenes, Escherichia coli, Listeria monocytogenes, Pasteurella haemolytica, P multocida, Salmonella typhimurium, Staphylococcus sp, and Streptococcus sp did not stain with this system, using anti-Brucella cell surface protein primary antibody, thus indicating specificity for Brucella organisms.
