Sixty-eight isolates of Campylobacter jejuni and C. coli isolated from patients with diarrhoea (n=630) and controls (n=220) at Tikur Anbassa Hospital, Addis Ababa, Ethiopia were serotyped on the basis of the heat-labile (HL) and the heat-stable (HS) antigens, by using 16 and 34 antisera, respectively, for the two methods. With the antisera against heat labile antigens, 89–3% of the C. jejuni and 75% of the C. coli were typable. The HL serotypes 1, 2, 3, 4, 5, 6 and 7 were the most common among the C. jejuni while HL serotypes 1 and 2 were dominant among the C. coli isolates. These serotypes accounted for 63·2% of all isolates. For the heat-stable antigens, 60% of the C. jejuni and 83·3% of the C. coli isolates were typable. The HS serotypes 1, 3, 8, 26 and 34 were most common among the C. jejuni, while serotypes 3 and 8 were dominant among C. coli isolates. This study shows that the most common HL and HS antigens among campylobacter isolates from Ethiopia correspond to the most frequent antigenic types from other parts of the world. A limited number of antisera were sufficient to identify the majority of the isolates.
