Molecular characterization of TLR4 genes of swamp and riverine types of water buffaloes was conducted to determine unique genotypic characteristics specific to each type of water buffalo and provide baseline information for explaining differences in disease resistance between each type. The nucleotide sequence of the riverine TLR4 gene produced 2,526 bp, whereas the swamp TLR4 sequence produced 2,322 bp. Riverine and swamp buffalo TLR4 nucleotide sequences were 99% similar to that of B. bubalis sequence from GenBank. The translated amino acid sequence of TLR4 showed that the riverine buffalo TLR4 sequence had a higher percentage similarity to B. bubalis sequence as compared to the swamp buffalo TLR4 amino acid sequence. Phylogenetic analysis confirmed the degree of relationship between the bubaline species and showed the distinctness of each breed. The predicted functional domains identified were 13 LRRs and a single LRRCT. Transmembrane protein and globular cytoplasmic domain TIR1 were found to be conserved regions.
