title: Studies on the major histocompatibility complex of indigenous cattle in the Ivory Coast.
abstract: The MHC (BoLA) type has been determined for cattle from three breeds in West Africa. Seventy Baoule, 50 N'Dama and 30 Zebu cattle from the centre and north of the Ivory Coast were tested. Lymphocytes from these cattle were tested in a lymphocytotoxicity test with alloantisera detecting all of the internationally recognised BoLA sera. 78 sera prepared in Edinburgh and 57 in Jouy-en-Josas were used in the study. The results showed that sera prepared in Europe detect similar specificities in West Africa. Although with some specificities the frequencies differ from those seen in Europe. The frequency of null alleles is higher than in Europe in the Ndama and Zebu animals indicating the existence of additional specificities which will require the production of alloantisera in these breeds. However in the Baoule the null allele frequency is lower even then in some European breeds. The population data in which no animals have more than two workshop specificities is consistent with a single locus control in West Africa as in Europe.
