Biological Typing of 161 Strains of Campylobacter Jejunum/Coli

One hundred and sixty one strains of Campylobacter jejunum/coli were isolated from human and anmals in Haizhu district of Guaagzhou city from June through October is 1984. These microbes were biologically typed according to Butzler's method(i,e based on the results of rapid hippurate hydrolysis,rapid H₂S and DNA hydrolysis tests, these microbes were divided into eight biological types) and their distributions in human and animals were compared. The results showed that Campylobacter jejunum type I was the predominant strain in both sick and healthy persons,amouated to 57.13% and 59.57% respectively.Campylobacter coli especially former type I, amounting to 69.23%.II came next, amounting to 12.77%-25.53% each.
