Patent ID: 7785778

Claim:
A method for identifying if a pig is resistant or non-resistant to an E. coli pathogen carrying fimbriae F4ac or F4 ab, the method comprising i) obtaining a sample from said pig, said sample comprising genomic material, ii) detecting in said genetic material the genotype of alleles of a genetic polymorphism indicative of resistance or susceptibility to said E. coli pathogen; iii) determining that said pig is resistant to said E. coli pathogen if the pig is homozygous for an allele of the genetic polymorphism indicative of resistance to ETEC; iv) determining that said pig is non-resistant to said E. coli pathogen and a non-carrier of resistance to said E. coli pathogen if the pig is homozygous for an allele of the genetic polymorphism indicative of non-resistance to said E. coli pathogen; and v) determining that said pig is non-resistant to said E. coli pathogen and a carrier of resistance to said E. coli pathogen if the pig is heterozygous and contains both an allele of the genetic polymorphism indicative of resistance to ETEC and an allele of the genetic polymorphism indiciative of non-resistance to said E. coli pathogen, wherein the allele of a genetic polymorphism indicative of resistance to ETEC is selected from the group consisting of: G at position 1849 of SEQ ID NO: 8; T at position 2129 of SEQ ID NO: 8; A at position 2997 of SEQ ID NO: 83; and C at position 3277 of SEQ ID NO: 83, and wherein the allele of a genetic polymorphism indicative of non-resistance to ETEC is selected from the group consisting of: C at position 1849 of SEQ ID NO: 8; C at position 2129 of SEQ ID NO: 8; G at position 2997 of SEQ ID NO: 83; and G at position 3277 of SEQ ID NO: 83.
