NOD2 and susceptibility to pneumonia measurement: In Baladi goats with pneumonia and healthy control group, PCR-DNA sequencing revealed SNPs linked to pneumonia susceptibility and resistance in immunological genes (SLC11A1, CD-14, CCL2, TLR1, TLR7, TLR8, TLR9, defensin, SP110, SPP1, BP1, A2M, ADORA3, CARD15, IRF3, and SCART1) [115].
