A total of 145 strains of thermophilic Campylobacter spry. isolated from the fecal specimens of 108 cattle, 120 pigs and 104 chickens.
The isolation rates of camplobacter jejuni from cattle, pigs and chickens were 36.1%, 38.3% and 28.8%, respectively.
In the biotyping of 115 strains of C. jejuni, 49.6% were belonged to biotype I, 33.9% biotype II, 10.4% biotype IV and 6.1% biotype III. Twenty-eight strains of C. coli were 78.6% of biotype I, 21.4% biotype II Two strains of C. laridis belonged to biotype I and II
One hundred of 105 C. jejuni cultures were typeable serologically and represented 13 serogroups. Serotype 4, 5, 26, 27 and 36 were encountered most frequently.
Eighteen of 23 C. coli cultures were typable serologically and represented 6 serogroups. Serotype 8, 20, 21 and 31 were encountered most frequently.
In the comparison of frequency of serotype between animal species, serotypes 4, 30, 5, 26 and 27 were encountered relatively common in the cattle source isolates, serotypes 26 and 36 in the pigs, and 36 and 17 in the chickens. The serotypes of C. coli encountered most frequently were serotype 8 and 31.
