Mastitis is one of the shocking maladies of milch animals causing high production losses to livestock industry in Pakistan and elsewhere in the world. Mastitis has been familiar as one of the most inexpensively important diseases affecting dairy animal’s worldwide.
Susceptibility and resistance to mastitis is a complex trait and influenced by genetic variation of the immunity genes of animals. Among these variations, the polymorphisms in Toll-like receptor 4 gene (TLR4) play important role in the immune response to mastitis. Polymorphism in exon 3 of TLR4 gene is associated with mastitis susceptibility and resistance. It is a potential candidate gene for screening of the mastitis susceptible and resistant dairy cows.
The present study was designed for the identification of polymorphism in TLR4gene associated with mastitis. Blood samples from 20 Sahiwal cows having clinical and subclinical mastitis were sampled. Blood sample of 10 normal Sahiwal cows was also collected. DNA was extracted. Specific primers for amplification of TLR4 gene were designed from NCBI.
TLR4gene was amplified and sequenced to get the desire sequence of this gene. Comparative analysis of the resulted sequences using NCBI BLAST was done.
