[Campylobacter jejuni infections in slaughterhouse workers].
Complement fixing (C.F.) antibodies to Campylobacter jejuni were detected in 83 slaughterhouse workers and 83 blood donors. Workers were aged 18-65 years (mean, 41.7 +/- 12.3) and had worked in the slaughterhouse for 2-40 years (mean, 17.5 +/- 5.1). C.F. antibodies were detected according to Mosimann's method and by including five antigens: Campylobacter jejuni, Yersinia enterocolitica types 03 and 09, Yersinia pseudotuberculosis and Brucella. Positive titers were found in 12.1% of workers and in 2.4% of control subjects (p less than 0.01); values ranged from 1:10 to 1:40. Frequent and close contact with animals or their products was significantly associated with seropositivity. No association was found with the time of employment. Sixty per cent of seropositive workers referred rheumatological symptoms. These findings confirm that slaughterhouse workers exposed to potential sources of C. jejuni have elevated titers of antibodies. Attention has, therefore, to be focused on breaking the chain of transmission as a means of control.
