Abstract

The Major Histocompatibility class II complex plays an extremely important role in disease resistance and susceptibility of Haemonchus contortus in sheep. Gastrointestinal nematodes constitute a major cause of morbidity and mortality in grazing ruminants. This study was designed to carry out the differential expression of DRB1 gene transcript in low and high fecal egg count animals by real time PCR. Animals were selected on the basis of fecal egg count (FEC). Blood was collected from jugular vein and mRNA was extracted by trizol method. Further, RT-qPCR was done to analyze the differential expression of DRB 1 exon 2 in Low FEC and high FEC animals. The expression level of DRB1 gene transcript was found to be higher in low FEC animals as compare to high FEC animals. Sheep showing resistance to Haemonchus contortus that is having Low FEC had lower (P < 0.05) DRB1*1101 expression than susceptible animals having high FEC.
