A low-molecular-weight recombinant B. abortus protein, reactive with antibodies from a variety of naturally and experimentally infected hosts and T lymphocytes from experimentally infected mice, was identified and designated BA14K. The gene encoding BA14K was cloned and characterized, and the predicted amino acid sequence of this immunoreactive protein showed no significant homology with previously described proteins. Sequences homologous to the cloned fragment encoding BA14K were identified by Southern blot analysis of genomic DNAs from representatives of all of the currently recognized Brucella species. It is suggested that studies using BA14K should contribute to the better understanding of the antigenic specificity of protective immunity to brucellosis. The EMBL/GenBank/DDBJ accession number for the new nucleotide sequence is U62541.
