Abstract
Duclos P J (Ecole Nationale Vetérinaire de Lyon BP31-69752, Charbonnières les Bains, Cédex, France), Bentejac M-C, Serre A and Bascoul S. Skin test reactions to a phenol-soluble antigen of Brucella abortus among veterinary students, Lyon, France, 1984. International Journal of Epidemiology 1989, 18: 446–450. In December 1984, 424 students at the National Veterinary College, Lyon, France, were skin-tested with a phenol-soluble antigen of Brucella abortus B 19. 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 (<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.Keywords
