Piglet diarrhea is one of the primary factors that affects the benefits of the swine industry. Recent studies have shown that exon 2 of the swine leukocyte antigen-DQA gene is associated with piglet resistance to diarrhea; however, the contributions of additional exon coding regions of this gene remain unclear. Here, we detected and sequenced variants in the exon 3 region and examined their associations with diarrhea infection in 425 suckling piglets using the polymerase chain reaction-single-strand conformational polymorphism and sequencing analysis.

Swine leukocyte antigen class II genes (SLA-DRA, SLA-DRB1, SLA-DQA, SLA-DQB1) polymorphism and genotyping in Guizhou minipigs

Z. Z. Liu, Xia, J. H., Xin, L. L., Wang, Z. G., Qian, L., Wu, S. G., Yang, S. L., and Li, K., Swine leukocyte antigen class II genes (SLA-DRA, SLA-DRB1, SLA-DQA, SLA-DQB1) polymorphism and genotyping in Guizhou minipigs, vol. 14, pp. 15256-15266, 2015.

The swine leukocyte antigen (SLA) complex harbors highly polymorphic gene clusters encoding glycoproteins that are involved in responses to vaccines, infectious disease, and production performance. Pigs with well-defined SLA class II genes are useful for the study of disease, immunology, and vaccines. In this study, we analyzed four SLA class II genes (SLA-DRA, SLA-DRB1, SLA-DQA, SLA-DQB1) in 22 founder Guizhou minipigs using a sequence-based typing method.
