Peptidoglycan and Lipoteichoic Acid Induces Differential mRNA Response of Immune-Related Genes in PBMC of Crossbred, Tharparkar Cattle and Murrah Buffalo

ABSTRACTSubclinical mastitis, generally caused by Staphylococcus aureus, has a global economic impact all over the world. Hence, it needs to be resolved on higher priority which may be attained via. selection of mastitis resistant animals or inclusion of mastitis resistant trait into herd apart from management care. Diverse hosts with various genetic make-ups encounter pathogens in a diverse manner which in turn leads to contradicting outcome of the disease. Identification of species-wise or breed-wise differential expressed genes in response to S. aureus through relative evaluation of transcripts may be useful for judging the immuno-competency of a species or breed toward mastitis. The present study was undertaken to examine the stimulant effect of S. aureus peptidoglycan (PGN) and lipoteichoic acid (LTA) on Peripheral blood mononuclear cells (PBMC) harvested from blood samples of crossbred cattle, Tharparkar cattle, and Murrah buffaloes. After 6 h of in vitro stimulation qRT-PCR was used to measure the ...
