[Serology and culture diagnosis of Campylobacter jejuni infections]

Campylobacter jejuni is known today as one of the most common pathogens in acute infectious enteritis. In 77 patients serological testing by complement fixation as well as stool cultures were performed. A campylobacter jejuni infection was identified in 53% by culture and in 64% by serology, only in 17% the diagnosis was made with both methods. We conclude, that because of these data stool culture and serological testing should be used simultaneously. The complement fixation technique shows an increase in serum titer one to three weeks after beginning of the illness and a decrease in serum titer after four to eight weeks. For this reason it is an appropriate method for the identification of acute infections.
