Through PCR-DNA sequencing in Baladi goats with and without pneumonia, SNPs linked to pneumonia susceptibility and resistance were discovered in the immunological (SLC11A1, CD-14, CCL2, TLR1, TLR7, TLR8, TLR9, defensin, SP110, SPP1, BP1, A2M, ADORA3, CARD15, IRF3, and SCART1) genes [41]. This evidence concerns the gene TLR7 and pneumonia.
