New blood group factors Es, Et and a new allele Ebdgjmt (E16) in the pig E blood group system.
By immunizing a miniature sow a monovalent reagent (later designated anti-Es) was prepared, detecting an alternative antigen to the Ej. Blood group factors Ej and Es thus form the fifth genetically closed E subsystem. Analyses of selected raw sera containing anti-Ej led to the determination of a further Ej subgroup (designated Et) which is antithetical, mutually excluding with the blood factor Er. New blood factor Et is inherited by alleles Edeghjmnt (= E9) and (= E16). The investigation in pig breeds kept in CSFR indicated that allele Edeghjmnt occurs in Black and White Prestice breed (qE9 = 0.076 +/- 0.010) while allele Edeghjmnr (= E14) only in miniature pigs (qE9 = 0.147 +/- 0.011) and in wild pigs. In an élite herd of Swedish Landrace kept in CSFR a new complex allele Ebdgjmt (= E16) was found. Its frequency in the population studied was 0.058 +/- 0.022.
