The Evidence of Brucella abortus Infection in Slaughterhouse Men

Men engaged in slaughtering and dressing meat show a higher incidence of Brucella abortus agglutinins than those in similar age and sex groups who are otherwise employed, where titres of 1 in 20 and upwards are observed. This applies especially to men who deal with cattle and sheep; no such increased incidence has been noted in men dealing with pigs. It would seem that a titre in the vicinity of 1 in 40 serves to indicate evidence of Brucella infection definitely greater than that likely to be found in the generality of the community.
