[Serologic typing of strains of Pasteurella haemolytica isolated from sheep].

Typed were a total of 85 strains of Pasteurella haemolytica isolated from lambs, weaned lambs, and adult sheep in cases of septicemia and broncho-pneumonia applying the hemagglutination-inhibition reaction and making use of capsule antigens and anti-capsule hyperimmune sera. It was found that 74 strains belong to biotype A, five belong to biotype T, and six remained untyped. Most wide spread in this country proved serotype A2--35 strains, followed by serotype A6--14 strains.
