Abstract
The bovine Major Histocompatibility Complex (MHC), also known as the Bovine Leucocyte Antigen (BoLA) complex, is the genomic region that encodes the most important molecules for antigen presentation to initiate immune responses. The first evidence of MHC in bovines pointed to a locus containing 2 antigens, one detected by cytotoxic antiserum (MHC class I) and another studied by mixed lymphocyte culture tests (MHC class II). The most studied gene in the BoLA region is the highly polymorphic BoLA-DRB3, which encodes a β chain with a peptide groove domain involved in antigen presentation for T cells that will develop and co-stimulate cellular and humoral effector responses. BoLA-DRB3 alleles have been associated with outcomes in infectious diseases such as mastitis, trypanosomiasis, and tick loads, and with production traits. To catalog these alleles, 2 nomenclature methods were proposed, and the current use of both systems makes it difficult to list, comprehend and apply these data effectively. In this review we have organized the knowledge available in all of the reports on the frequencies of BoLA-DRB3 alleles. It covers information from studies made in at least 26 countries on more than 30 breeds; studies are lacking in countries that are important producers of cattle livestock. We highlight practical applications of BoLA studies for identification of markers associated with resistance to infectious and parasitic diseases, increased production traits and T cell epitope mapping, in addition to genetic diversity and conservation studies of commercial and creole and locally adapted breeds. Finally, we provide support for the need of studies to discover new BoLA alleles and uncover unknown roles of this locus in production traits.

Abstract
Mastitis is one of the most frequently encountered diseases in dairy cattle, negatively affecting animal welfare and milk production. For this reason, contributions to understanding its genomic architecture are of great interest. Genome-wide association studies (GWAS) have identified multiple loci associated with somatic cell score (SCS) and mastitis in cattle. However, most of the studies have been conducted in different parts of the world on various breeds, and none of the investigations have studied the genetic architecture of mastitis in Romanian dairy cattle breeds up to this point in time. In this study, we report the first GWAS for SCS in dairy cattle breeds from Romania. For GWAS, we used an Axiom Bovine v3 SNP-chip (>63,000 Single Nucleotide Polymorphism -SNPs) and 33,330 records from 690 cows belonging to Romanian Spotted (RS) and Romanian Brown (RB) cattle. The results found one SNP significantly associated with SCS in the RS breed and 40 suggestive SNPs with -log10 (p) from 4 to 4.9 for RS and from 4 to 5.4 in RB. From these, 14 markers were located near 12 known genes (AKAP8, CLHC1, MEGF10, SATB2, GATA6, SPATA6, COL12A1, EPS8, LUZP2, RAMAC, IL12A and ANKRD55) in RB cattle, 3 markers were close to ZDHHC19, DAPK1 and MMP7 genes, while one SNP overlapped the HERC3 gene in RS cattle. Four genes (HERC3, LUZP2, AKAP8 and MEGF10) associated with SCS in this study were previously reported in different studies. The most significant SNP (rs110749552) associated with SCS was located within the HERC3 gene. In both breeds, the SNPs and position of association signals were distinct among the three parities, denoting that mastitis is controlled by different genes that are dependent according to parity. The current results contribute to an expansion in the body of knowledge regarding the proportion of genetic variability explained by SNPs for SCS in dairy cattle.

Abstract
Background: The dairy sector is one of the leading in agricultural production sectors in the world and the bovine herpesvirus 1 (BoHV-1) is an important pathogen that causes great losses in most production systems. Moreover, BoLA DRB3 immunological gene presents different alleles related to protection against many pathogens. Methods: Serological diagnosis was carried out to determine the BoHV-1 infection and through PCR-RFLP 506 Holstein cows from several municipalities of Antioquia were genotyped for BoLA DRB3.2 gene polymorphisms. Results: Alleles 8, 16, 22, and 24 were the most common out of the 42 alleles found. By indirect ELISA technique, a 58.7% prevalence of BoHV-1 infection in this population was diagnosed and Odd ratios for found alleles were calculated by logistic regression; the only significant association was held for allele 37, which showed that it effects confers susceptibility to infection. On the other hand, by using generalized linear models, a significant association between BoLA DRB3.2 gene and milk and fat yield in primiparous and services per conception in multiparous was found, with the most favorable alleles being 11 and 28 in primiparous and 22 and 28 in multiparous; allele 37 was unfavorable only in primiparous. Conclusion: BoLA DRB3.2 gene polymorphisms have shown high variability and significant effects on Holstein cattle and their performance in production systems in Antioquia are at both sanitary or health and productive levels.

Abstract
Genetic polymorphisms and diversity of BoLA-DRB3.2 are essential because of DRB3 gene's function in innate immunity and its association with infectious diseases resistance or tolerance in cattle. The present study was aimed at assessing the level of genetic diversity of DRB3 in the exon 2 (BoLA-DRB3.2) region in African, American and Asian cattle breeds. Amplification of exon 2 in 174 cattle revealed 15 haplotypes. The breeds with the highest number of haplotypes were Brangus (10), Sokoto Gudali (10) and Dajal (9), while the lowest number of haplotypes were found in Holstein and Sahiwal with 4 haplotypes each. Medium Joining network obtained from haplotypic data showed that all haplotypes condensed around a centric area and each sequence (except in H-3, H-51 and H-106) representing almost a specific haplotype. The BoLA-DRB3.2 sequence analyses revealed a non-significant higher rate of non-synonymous (dN) compared to synonymous substitutions (dS). The ratio of dN/dS substitution across the breeds were observed to be greater than one suggesting that variation at the antigen-binding sites is under positive selection; thus increasing the chances of these breeds to respond to wide array of pathogenic attacks. An analysis of molecular variance revealed that 94.01 and 5.99% of the genetic variation was attributable to differences within and among populations, respectively. Generally, results obtained suggest that within breed genetic variation across breeds is higher than between breeds. This genetic information will be important for investigating the relationship between BoLADRB3.2 and diseases in various cattle breeds studied with attendant implication on designing breeding programs that will aim at selecting individual cattle that carry resistant alleles.

Abstract
Productivity in dairy cattle and buffaloes depends on the genetic factors governing the production of milk and milk constituents as well as genetic factors controlling disease resistance or susceptibility. The immune system is the adaptive defense system that has evolved in vertebrates to protect them from invading pathogens and also carcinomas. It is remarkable in the sense that it is able to generate an enormous variety of cells and biomolecules which interact with each other in numerous ways to form a complex network that helps to recognize, counteract, and eliminate the apparently limitless number of foreign invading pathogens/molecules. The major histocompatibility complex which is found to occur in all mammalian species plays a central role in the development of the immune system. It is an important candidate gene involved in susceptibility/resistance to various diseases. It is associated with intercellular recognition and with self/nonself discrimination. It plays major role in determining whether transplanted tissue will be accepted as self or rejected as foreign.

Abstract
The present study was performed to evaluate the genetic polymorphism of BoLA-DRB3.2 locus in Malnad Gidda, Hallikar and Ongole South Indian Bos indicus cattle breeds, employing the PCR-RFLP technique. In Malnad Gidda population, 37 BoLA-DRB3.2 alleles were detected, including one novel allele DRB3*2503 (GenBank: HM031389) that was observed in the frequency of 1.87%. In Hallikar and Ongole populations, 29 and 21 BoLA-DRB3.2 alleles were identified, respectively. The frequencies of the most common BoLA-DRB3.2 alleles (with allele frequency > 5%), in Malnad Gidda population, were DRB3.2*15 (10.30%), DRB3*5702 (9.35%), DRB3.2*16 (8.41%), DRB3.2*23 (7.01%) and DRB3.2*09 (5.61%). In Hallikar population, the most common alleles were DRB3.2*11 (13.00%), DRB3.2*44 (11.60%), DRB3.2*31 (10.30%), DRB3.2*28 (5.48%) and DRB3.2*51 (5.48%). The most common alleles in Ongole population were DRB3.2*15 (22.50%), DRB3.2*06 (20.00%), DRB3.2*13 (13.30%), DRB3.2*12 (9.17%) and DRB3.2*23 (7.50%). A high degree of heterozygosity observed in Malnad Gidda (H(O) = 0.934, H(E) = 0.955), Hallikar (H(O) = 0.931, H(E) = 0.943) and Ongole (H(O) = 0.800, H(E) = 0.878) populations, along with F(IS) values close to F(IS) zero (Malnad Gidda: F(IS) = 0.0221, Hallikar: F(IS) = 0.0127 and Ongole: F(IS) = 0.0903), yielded nonsignificant P-values with respect to Hardy-Weinberg equilibrium probabilities revealing, no perceptible inbreeding, greater genetic diversity and characteristic population structure being preserved in the three studied cattle populations. The phylogenetic tree constructed based on the frequencies of BoLA-DRB3.2 alleles observed in 10 Bos indicus and Bos taurus cattle breeds revealed distinct clustering of specific Bos indicus cattle breeds, along with unique genetic differentiation observed among them. The results of this study demonstrated that the BoLA-DRB3.2 is a highly polymorphic locus, with significant breed-specific genetic diversities being present amongst the three studied cattle breeds. The population genetics and phylogenetic analysis have revealed pivotal information about the population structure and importance of the presently studied three Bos indicus cattle breeds as unique animal genetic resources, which have to be conserved for maintaining native cattle genetic diversity.

Abstract
The role of the major histocompatibility complex (MHC) in the immune response makes it an attractive candidate gene for associations with disease resistance and susceptibility. This study describes genetic variability in the BoLA-DRB3 in Iranian buffaloes. Heminested PCR-RFLP method was used to identify the frequency of BoLA-DRB3 alleles. The BoLA-DRB3 locus is highly polymorphic in the study herd (12 alleles). Almost 63.50% of the alleles were accounted for by four alleles (BoLA-DRB3.2 ∗48, ∗20, ∗21, and obe) in Iranian buffalo. The DRB3.2 ∗48 allele frequency (24.20%) was higher than the others. The frequencies of the DRB3.2 ∗20 and DRB3.2 ∗21 are 14.52 and 14.00, respectively, and obe and gbb have a new pattern. Significant distinctions have been found between Iranian buffalo and other cattle breed studied. In the Iranian buffaloes studied alleles associated with resistance to various diseases are found.

Abstract
In the present study, the exon 2 and 3' end sequence of intron 1 of BoLA-DRB3 gene of 211 Beijing Holstein cows was amplified and a uniform fragment of 284 bp was obtained. The genetic polymorphism was investigated by PCR-RFLP using two restriction endonucleases HaeIII and BstYI. Seven genotypes were detected by digesting the PCR products with HaeIII. The frequency of AA, AB, AC, AD, BB, BC and BF genotypes was 0.4638, 0.0193, 0.0193, 0.3478, 0.0290, 0.0386 and 0.0822, respectively. Three genotypes were found by digesting the PCR products with BstYI. The frequency of AA, AB and BB genotypes was 0.0569, 0.2844 and 0.6587, respectively. The relationship between the polymorphisms in exon 2 of BoLA-DRB3 gene and somatic cell score (SCS) in Beijing Holstein cows was analyzed by least squares linear model. No significant difference was detected among least squares means of SCS for seven HaeIII-RFLP genotypes (P > 0.05). As for BstYI-RFLP analysis, least squares mean of SCS for AA was significantly lower than that for AB (P < 0.05) or BB (P < 0.05), and no significant difference was detected between AB and BB genotypes (P > 0.05). BstYI AA was the most favorable genotype and BstYI BB was the most unfavorable genotype for mastitis resistance. The information found in the present study is very important for improving mastitis resistance in dairy cattle by marker assisted selection.

Abstract
The association of the polymorphism of bovine leukocyte antigen (BoLA-DRB3) genes identified by the polymerase chain reaction sequence-based typing (PCR-SBT) method with resistance and susceptibility to mastitis caused by pathogenic bacteria was investigated. Blood samples for DNA extraction were collected from 194 Holstein cows (41 healthy cows and 153 mastitis cows including 24 mixed-infection cows infected with 2 or 3 species of pathogens) from 5 districts of Chiba prefecture, Japan. Sixteen BoLA-DRB3 alleles were detected. The 4 main alleles of DRB3*0101, *1501, *1201, and *1101 constituted 56.8% of the total number of alleles detected. Mastitis cows were divided into 2 groups: group 1 with single-infection cows and group 2 with all mastitis cows including 24 mixed-infection cows. The differences in the frequencies of BoLA-DRB3 alleles and the number of cows homozygous or heterozygous for each BoLA-DRB3 allele between healthy cows and the 2 groups of mastitis cows were evaluated. Furthermore, similar comparisons were performed between healthy cows and the 2 groups of mastitis cows for each mastitis pathogen. It was considered that the 4 alleles, namely, DRB3*0101, *1501, *1201, and *1101 had specific resistance and susceptibility to 4 different mastitis pathogens. Thus, DRB3*0101 might be associated with susceptibility to coagulase-negative Staphylococci and Escherichia coli, and DRB3*1501 might be associated with susceptibility to Escherichia coli. However, DRB3*1101 might be associated with resistance to Streptococci and coagulase-negative Staphylococci, and DRB3*1201, with resistance to Streptococci, Escherichia coli, and Staphylococcus aureus.

Abstract
The major histocompatibility complex (MHC) is a gene complex closely linked to the vertebrate immune system due to its importance in antigen recognition and immune response to pathogens. To improve our understanding of the MHC and disease resistance in dairy cattle, we gathered 5119 test day records of somatic cell count (SCC) and performance traits of 262 Holstein dairy cows to determine whether the DRB region of the MHC contains alleles that are associated with elevated SCC, milk yield, protein and fat percent of milk. To this purpose, genotyping of animals for DRB3 gene was investigated by polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP) assay. A two-step PCR was carried out so as to amplify a 284 base-pair fragment of exon 2 of the target gene. Second PCR products were treated with three restriction endonuclease enzymes RsaI, BstYI and HaeIII. Twenty-eight BoLA-DRB3 alleles were identified including one novel allele (*40). The results in general are in good accordance with allele frequencies of Holstein cattle populations reported by previous studies. Analyses of associations were modeled based on repeated measurement anova and generalized logistic linear methods for production traits and SCC data, respectively. The results of this study showed a significant relationship between the elevated SCC reflecting an increased probability of occurrence to subclinical mastitis and DRB3.2 allele *8 (p < 0.03). The results also revealed significant positive relationships of alleles*22 (p < 0.01) and allele*11 (p < 0.05) with milk fat percent as well as of alleles*24 (p < 0.03) and *22 (p < 0.05) with protein percent. The present study failed to find any association between milk yield and tested alleles. Because of the lack of consistency among results of similar studies, we suggest further investigations to determine the precise nature of these associations with the high polymorphic bovine MHC region to be performed based on haplotypes.

Abstract
Bovine leukocyte antigen DRB3 alleles from Holstein x Zebu crossbred dairy cows (n = 409) were analyzed using the PCR-RFLP technique. Exon II of DRB3 was amplified using locus-specific primers (HLO30/HLO32), followed by digestion with 3 restriction enzymes (RsaI, BstyI, and HaeIII). Forty alleles were found with frequency ranging from 0.005 to 0.139. The most frequently detected alleles of Holstein x Zebu were DRB3*16, *51, *23, *11, *8, and *1, accounting for 61.12% of the alleles in the population. Detection of candidate alleles for clinical mastitis occurrence was performed by logistic regression. It was found that percentage of Holstein fraction in crossbred cows had a nonsignificant effect (P > 0.05). However, parity had a significant effect on mastitis occurrence. In addition, DRB3*1 and *52 were the most associated with the occurrence of clinical mastitis, whereas *15, *51, and *22 were associated with resistance in crossbred populations. This is the first report of association of DRB3*15 and *51 with mastitis resistance. The association was validated by examining the candidate alleles in another commercial population. Highly susceptible (n = 43) and resistant (n = 42) groups of Holstein x Zebu cows were investigated. The result confirmed that DRB3*1 and *52 could be considered as susceptibility alleles, whereas *15, *51, and *22 could be considered as resistant alleles in Holstein x Zebu raised under tropical conditions. In addition, allele effects on 305-d milk production were estimated by BLUP. It was shown that most alleles associated with high clinical mastitis occurrence were related to increased milk yield. This study revealed that allele DRB3*10 had the greatest effect on increasing milk yield with moderate resistance to clinical mastitis, which could be used as a potential marker for selection in dairy genetic evaluation.

Abstract
Bovine lymphocyte antigen DRB 3.2 (BoLA-DRB3.2) gene encodes for the beta chain of the major histocompatibility complex (MHC) class II molecule in cattle, which is a glycoprotein present on the surface of antigen-presenting cells. This locus shows extensive polymorphism in it. The objective of the present study was to genotype the BoLA-DRB3.2 locus in Kankrej cattle (n = 50) by PCR-RFLP. Bovine DNA was isolated from aliquots of whole blood. Primers specific for exon 2 of the bovine lymphocyte antigen (BoLA)-DRB3 gene were used to amplify the region. The 304-bp amplified product of the DRB3 gene was separately digested with restriction endonucleases RsaI, BstYI, and Hae III. Twenty-four BoLA-DRB 3.2 alleles were identified with frequencies ranging from 1 to 22.0%. Twenty-one alleles of the total 24 alleles were similar to those reported earlier; 3 alleles were new and had not been reported previously. The allele BoLA-DRB3.2*34 occurred at the highest frequency of 22% (approx.) in the Kankrej animals studied. Six alleles (BoLA-DRB3.2 *34, *15, *06, *20, *37, and *20) accounted for almost 71% of the total alleles observed to be present in the Kankrej animals. All the new alleles observed were present at frequencies of 1%. The results obtained in the present study demonstrated that the BoLA DRB3.2 locus is highly polymorphic in the Kankrej cattle.

Abstract
Genotyping of bovine leucocyte antigen DRB3.2 (BoLA-DRB3.2) in a total of 523 Norwegian Red (NR) cows from two groups selected for high protein yield and low clinical mastitis, respectively, identified 27 previously reported BoLA-DRB3.2 alleles across the groups. Significant differences in BoLA-DRB3.2 allele frequencies were found between the selection groups. Alleles *13, *18, *22 and *27 had a significantly higher frequency in cows selected for low clinical mastitis, while alleles *3, *9, *11 and *26 had a higher frequency in cows selected for high protein yield. Associations between BoLA-DRB3.2 alleles and clinical mastitis were analysed based on mastitis data from 741,072 first-lactation NR cows, of which 452 were genotyped. Alleles *22 and *26 were found to be associated with increased clinical mastitis, while alleles *7, *11, *18 and *24 had a favourable effect on mastitis resistance. Contradictory results from different studies investigating associations between BoLA-DRB3.2 alleles and mastitis indicate that future studies should focus on associations of mastitis with BoLA haplotypes rather than with single BoLA genes.

Abstract
Major Histocompatibility Complex (MHC) class II locus DRB3 was investigated by PCR based restriction fragment length polymorphism (PCR-RFLP) assay. A total of 262 Holstein cows participating in the national recording system were sampled from 10 herds. A two-step polymerase chain reaction was carried out in order to amplify a 284 base-pair fragment of exon 2 of the target gene. Second PCR products were treated with three restriction endonucleas enzymes RsaI, BstYI and HaeIII. Digested fragments were analyzed by polyacrylamid gel electrophoresis. Twenty-eight BoLA-DRB3 alleles were identified. Identified alleles are: BoLA-DRB3.2 *3, *6, *7, *8, *9, *10, *11, *12, *13, *14, *15, *16,20, *21, *22, *23, *24, *25, *26, *27, *28, *32, *36, *37, *40, *51, *iaa and *ibb. The BoLA-DRB3.2*40 allele that was observed in this study has not been reported previously. The calculated frequencies were as follows: 2.29, 1.34, 0.19, 14.5, 0.38, 3.05, 12.21, 1.34, 2.29, 1.34, 2.48, 9.16, 0.95, 0.77, 6.68, 9.16, 17.94, 1.15, 0.57, 1.15, 0.95, 0.57, 0.38, 1.91, 0.38, 5.73, 0.19 and 0.95% respectively. The six most frequently observed alleles (BoLA-DRB3.2 *8, *11, *16, *22, *23 and *24) accounted for 69.65% of the alleles in these 10 herds. The results of this study confirm the allelic distribution of six most frequent alleles in Holstein population's worldwide.

Abstract
A associação entre os alelos do loco BoLA-DRB3.2, identificados pela técnica de PCR-RFLP, e a produção de leite na raça Gir foi estudada por meio da análise de dados moleculares e fenotípicos de 424 vacas Gir, utilizando um modelo misto, sob modelo animal. Os dados moleculares consistiam dos genótipos dos animais para os alelos do loco BoLA-DRB3.2 e os dados fenotípicos eram referentes à produção de leite em até 305 dias de lactação. O loco é altamente polimórfico nesta raça, sendo identificados sete alelos (BoLA-DRB3.2*4, *8, *11, *19, *28, *41 e *48) que não haviam sido encontrados em animais zebuínos. Dois alelos (*16 e *29) estavam significativamente associados com maiores produções de leite, sugerindo que o próprio loco BoLA-DRB3.2 ou um QTL a ele ligado influencia a produção de leite de vacas Gir.

Abstract
BoLA-DRB3 is a gene of the major histocompatibility complex (MHC) in cattle. The product of the BoLA-DRB3 gene is a beta chain of an MHC class II molecule, a glycoprotein expressed on the surface of antigen-presenting cells (APCs). Responses of CD4+ T lymphocytes to peptides are dependent on the presentation of peptide ligands bound to class II molecules on APCs. Genotyping of the BoLA-DRB3 gene is relatively complex due to the extensive polymorphism of this locus. Current techniques for assignment of genotypes are polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), direct sequencing of PCR products, cloning-sequencing, polymerase chain reaction using sequence-specific oligonucleotide probes (PCR-SSOP), and denaturant-gradient gel electrophoresis. These techniques are time-consuming, do not discriminate all possible alleles, or are not readily reproducible. The objective of this study was to genotype BoLA-DRB3 using temperature-gradient gel electrophoresis (TGGE) to separate alleles before sequencing. PCRs using 28 DNA samples from Gir Dairy cattle (a Brazilian breed of Bos indicus) were submitted to TGGE. New PCR products were generated from separated alleles, purified, and sequenced. Allele separation was possible in 21 out of 26 heterozygote samples (81%). Results indicate that two sequence reads (forward and reverse) were sufficient for accurate genotyping of BoLA-DRB3 alleles. Separation of alleles by TGGE provides high-throughput, reliable typing of BoLA-DRB3, which is critical in disease association studies in cattle.

Abstract
We sequenced exon 2 of the major histocompatibility complex (MHC) class II DRB3 gene from 471 individuals in four different Japanese populations of cattle (201 Japanese Black, 101 Holstein, 100 Japanese Shorthorn, and 69 Jersey cattle) using a new method for sequence-based typing (SBT). We identified the 34 previously reported alleles and four novel alleles. These alleles were 80.0-100.0% identical at the nucleotide level and 77.9-100.0% identical at the amino acid level to the bovine MHC (BoLA)-DRB3 cDNA clone NR1. Among the 38 alleles, eight alleles were found in only one breed in this study. However, these alleles did not form specific clusters on a phylogenetic tree of 236-base pairs (bp) nucleotide sequences. Furthermore, these breeds exhibited similar variations with respect to average frequencies of nucleotides and amino acids, as well as synonymous and non-synonymous substitutions, in all pairwise comparisons of the alleles found in this study. By contrast, analysis of the frequencies of the various BoLA-DRB3 alleles in each breed indicated that DRB3*1101 was the most frequent allele in Holstein cattle (16.8%), DRB3*4501 was the most frequent allele in Jersey cattle (18.1%), DRB3*1201 was the most frequent allele in Japanese Shorthorn cattle (16.0%) and DRB3*1001 was the most frequent allele in Japanese Black cattle (17.4%), indicating that the frequencies of alleles were differed in each breed. In addition, a population tree based on the frequency of BoLA-DRB3 alleles in each breed suggested that Holstein and Japanese Black cattle were the most closely related, and that Jersey cattle were more different from both these breeds than Japanese Shorthorns.

Abstract
The ovine major histocompatibilty complex (Ovar) class II DRB1 second exon was amplified by polymerase chain reaction (PCR) from DNA samples of 52 Suffolk sheep. Polymerase chain reaction products were characterized by the restriction fragment length polymorphism (RFLP) technique using nine restriction enzymes, RsaI, HaeIII, SacI, SacII, DdeI, NciI, Hin1I, EcoRI, and BstNI, yielding 13 types. Sequencing of cloned PCR products identified 16 Ovar-DRB1 alleles. Collectively, all PCR-RFLP patterns exactly matched those predicted from DNA sequences. These findings strongly indicate that the PCR-RFLP method using a combination of nine restriction endonucleases is a very powerful tool in Ovar typing.

Abstract
To investigate the genetic diversity of the sheep MHC (Ovar) class II DRB1 locus, we amplified exon 2 of Ovar-DRB1 alleles by polymerase chain reaction (PCR) and determined the nucleotide sequences of both resultant strands after cloning. In our study of a total of 97 sheep of three breeds, namely, Suffolk, Cheviot and Corriedale, we identified 18 previously published alleles and 17 new alleles. These alleles were 83.4 to 94.1% identical at the nucleotide level and 71.4 to 90.9% identical at the amino acid level to Ovar-DRB1*0101. We identified six new alleles in Cheviot sheep and 11 new alleles in Suffolk sheep. Furthermore, we identified 15, 6 and 1 allele in Suffolk, Cheviot and Corriedale sheep, respectively, that have only been found in these breeds to date. Analysis of the frequencies of the various Ovar-DRB1 alleles in each breed indicated that Ovar-DRB1*0702 was the most frequent allele in Suffolk sheep (23.9%), Ovar-DRB1*0203 was the most frequent allele in Cheviot sheep (27.5%) and Ovar-DRB1*0201 was the most frequent allele in Corriedale sheep (25.0%). A comparative analysis of the positions of polymorphic residues in the first extracellular domain of the DRB genes of sheep, humans and mice revealed an extraordinary similarity amongst the positions of polymorphic residues that are associated with the antigen recognition site (ARS). Moreover, the extent of polymorphism seems to be similar in sheep, humans and mice.

Abstract
Brazilian dairy Gir (Bos indicus) cattle are a tropical, well-adapted breed, for which no information on the major histocompatibility complex (MHC) is presently available. The second exon of the bovine lymphocyte antigen (BoLA-DRB3) was amplified by polymerase chain reaction (PCR) of DNA samples from 28 Brazilian dairy Gir cows. Two experimental genotyping approaches were used: direct sequencing of PCR gene products (PCR-DS) and sequencing of cloned PCR fragments (S-CLO). Results demonstrate the viability of both typing approaches. PCR-DS allowed typing of 39% of the animals while the remainder were genotyped by S-CLO. Seventeen BoLA-DRB3 alleles were assigned, including some that were only recently described for zebu cattle. Allelic frequencies ranged from 0.02 to 0.18. The most frequent alleles were *3601 (frequency = 0.18), *2201 (0.14) and *2101 (0.11).

Abstract
A study was made of exon 2 of the bovine leukocyte antigen BoLA-DRB3 gene of 176 Japanese Shorthorn cattle at six farms in Japan using polymerase chain reaction-sequence-based typing (PCR-SBT). An initial round of PCR using conserved locus-specific primers, a second round of PCR using a locus-specific primer, and at least one sequence-specific primer (SSP), followed by direct sequencing of products of PCR with SSP were conducted. Twenty-one BoLA-DRB3 alleles were identified with frequencies ranging from 0.3 to 19.6% in 176 individuals, and two of these alleles were new alleles that have not been reported previously. The three most frequently observed alleles (DRB3*1201, *0301, and *0801) accounted for 43.8% of the alleles in the population of these herds. Next, we tested the products of amplification by PCR of BoLA-DRB3 exon 2 with RsaI, BstYI, and HaeIII, and identified 18 previously described PCR-restriction fragment length polymorphism (RFLP) types. The PCR-RFLP types reflected the results of PCR-SBT exactly. Our results indicate that exon 2 of the BoLA-DRB3 gene is highly polymorphic in Japanese Shorthorn cattle.
