摘要:

SummaryMethods of production and characterization of immune typing reagents reactive with the erythrocytes of the dog are described. Five of the reagents (agglutinins) were reactive with previously unknown blood group factors and were shown by statistical and genetic tests on 222 random samples and 28 families to belong to 5 previously unrecognized blood group systems. The five new systems were one‐blood factor, two‐allele, three‐genotype systems like the B, C, D and F systems. These were arbitrarily named J, K, L, M

摘要:

SummaryA previously unrecognized canine red cell antigen, tentatively named O, was found after absorption analysis of an alloimmune antiserum and absorption of several immune or naturally occurring cross‐reacting heteroantibodies from man, cattle and swine. The serological results and genetic analysis of a limited number of complete dog families indicated that the new factor probably belongs to the Tr blood group system. No individual possessed both factors Tr and O, and a large proportion of animals was negative for both factors. The serological pattern for the new Tr system obtained was consistent with similar systems observed in sheep (A‐O), pig (R‐O) and man (Bombay) in which the gene for one factor was dominant over and masked the gene for the second factor in the system. The negative phenotype was accounted for by the actions of an epistatic

摘要:

SummaryBlood samples were collected from more than 100 animals in each of 2 Spanish cattle breeds (Retinto and De Lidia), 2 Portuguese breeds (Alentejana and Mertolenga), and American Longhorn cattle. All samples for the 4 Iberian breeds were tested for 20 polymorphic systems; American Longhorn were tested for 19 of the 20. For each breed an average inbreeding coefficient was estimated by a comparison of the observed and expected heterozygosity at 7 or 8 codominant systems tested. All breeds had positive values but only 3 breeds had estimates of inbreeding that were statistically significantly different from 0: De Lidia with f̄= 0.17, Retinto with f̄= 0.08 and Mertolenga with f = 0.05. The De Lidia breed especially may be suffering from inbreeding depression since this high value is greater than expected if all of the animals were progeny of half‐sib matings. Genetic distances were calculated from the gene frequency data on these 5 breeds plus 9 other European breeds. Analyses of these distances show a closely related group of the 4 Iberian breeds and American Longhorn, confirming the close relationships among the Iberian breeds and the Iberian, probably Portuguese, origin of American Longhorn cat

摘要:

SummaryThe blood protein polymorphism of serum albumin, haptoglobin, transferrin, ceruloplasmin and haemoglobin have been studied in 135 samples from one‐humped Arabian camel(Camelus dromedarius)of the Sudan by starch gel electrophoresis. Only the serum albumin and haptoglobin systems exhibited polymorphism with the estimated frequencies of 0.0222, 0.2227 and 0.7773 for Albv, Hp1Hp0respectively. The frequency of Hp was 0.0325. No electrophoretic variant was observed at transferrin, ceruloplasmin and haemoglobin loci in the camel. The activity of the ceruloplasmin of the camel sera was wea

摘要:

SummaryA total of 146 East African Zebu, 41 Zebu‐Hereford crosses and 24 Ayrshire‐Norwegian Red Cattle crosses have been investigated with cattle red cell reagents characterizing blood factors in eleven systems. With a battery of 36 selected reagents the average number of blood factors in Zebu was 20.1 which differs significantly from the average of 12.5 in the Ayrshire crosses. Factor frequencies for the A, C and S systems and gene frequencies for the F, L, M, Z, R' and T' systems are presented. The B system factors in four Zebu bulls could be grouped into eight different phenogroups by utilizing the blood types of dam‐offspring

摘要:

SummaryAlthough chymotrypsin treatment eliminated the reactivity of many antigenic determinants on the bovine red cell, haemolytic inhibition tests, double diffusion in agar tests, and immunizations provided no conclusive evidence of any of the affected determinants in the soluble digest. Chymotryptic digestion unmasked an apparent cryptantigen, rendering Q‐positive cells reactive with a previously Q‐negative antise
