[Serologic survey of brucellosis in the personnel of an abattoir in San Luis, Argentina].
Blood samples obtained from 256 workers of an abattoir were tested for brucellosis antibodies and 11.7% were found reactive. The highest rate was 44.2% among those who had contact with blood and viscera, and 26.1% among workers at slaughter section. Four tests were used: plaque agglutination (PA), tube agglutination (TA), card test (CT) and complement fixation (CF). The highest number of positive reactions was obtained by the PA and TA tests, with a complete coincidence in both results. When both test titers were the same or less than 50 IU, CF and CT yielded less percentage of positive results. When titers were higher than 50 IU, CT but CF showed concordance between the results.
