Skin test reactions to a phenol-soluble antigen of Brucella abortus among veterinary students, Lyon, France, 1984.
In December 1984, 424 students at the National Veterinary College, Lyon, France, were skin-tested with a phenol-soluble antigen of Brucella abortus B19. Of all students, 2.6% had a positive intradermal reaction indicating previous contact with Brucella. Prevalence of positive reactions was significantly lower among students from the three first school years (less than 2%) compared with students in their last school year (5.9%). These results are discussed and compared to the prevalence of brucellosis among cattle. Specificity (94%) of the intradermal testing resembles that of serological testing but its sensitivity (75%) seems to be better.
