Several studies have revealed the association between NRAMP-1 and iNOS genes against disease resistance, including the associations with tuberculosis in humans (Medapati et al, 2017;Mahmud et al, 2017), salmonella disease in mice (Bauler et al, 2017;Reventun et al, 2017), tuberculosis in cattle (Pereira-Suárez et al, 2006;Delgado et al, 2010), the nature of immunity in pigs (Dai et al, 2017;Yan et al, 2017), Rhodococcus equi pneumonia in horses (Halbert et al, 2006), salmonella and viruses in goats and sheep (Lantier et al, 2012;Dincel & Kul, 2015;), and S. enteritidis in chickens (Kramer et al, 2003;Tohidi et al, 2013;Jin et al, 2015;Psifidi et al, 2016;Sun et al, 2017).…”
