Relationship between transferrin and ceruloplasmin polymorphism and the frequency of diarrhoea in piglets

Abstract. The relationship between a phenotype of transferrin (Tf) and ceruloplasmin (Cp) and the frequency of diarrhoea occurrence was analysed in 317 piglets. It was observed that diarrhoea caused by haemolytic Escherichia coli strains including K88 ab and K88 ac occurred with greater frequency in piglets with phenotypes Tf AB and Cp AB than in piglets with phenotypes Tf BB and Cp BB. It is believed that Polymorphie type of Tf A and Cp A is related with piglets susceptibility to colibacteriosis which is caused by strains E. coli K88 ab and K88 ac.
