This study assessed the expression of an important TLR9 gene in spontaneous bovine sub-clinical and clinical mastitis caused by E. coli. The total RNA was isolated from milk somatic cells converted as cDNA using oligo (dT) primers. Relative quantitation of mRNA of TLR9 was analysed by RT-qPCR system. The mRNA expression of TLR9 gene in sub-clinical mastitis was higher ( fold) than clinical case ( fold) when compared to normal bovine case. |
