Serological data for Salmonella and Infectious Bursal Disease Virus (IBDV) were recorded for 760 indigenous Ethiopian village chickens raised in two distinct geographical regions, Horro and Jarso. Chickens were genotyped with a 620K SNP array. A multidimensional scaling analysis showed that the two populations were genetically distinct. In Horro, genome-wide scans revealed nine SNP with chromosome-wide significant association with Salmonella resistance and seven SNP with genome-wide significant association with IBDV resistance. In Jarso, these scans revealed one SNP with genome-wide and two SNP with chromosome-wide significant association with Salmonella resistance, and one SNP with genome-wide and three SNP with chromosome-wide significant association with IBDV resistance. All significant SNP for each region for either disease were located on different chromosomes. Most of these SNP had a significant additive effect and were located close to annotated genes that are known to impact the immune response in chickens.
