In enzootic areas the prevalence estimates of canine leishmaniosis are high whereas only a proportion of dogs exhibit the clinical disease, thus implying a role of host genetics. The type of the triggered immune response remains a crucial determining factor for the diverse outcome of this parasitosis. The Solute Carrier Family 11 member 1 (SLC11A1) is a protein, which plays a central role in macrophage function and is implicated in the regulation of the immune response. An extended study with 73 resistant and 75 susceptible to Leishmania dogs was conducted. A fragment of the promoter region of the canine SLC11A1 gene was amplified and digested providing the different genotypes for three previously recorded single-nucleotide polymorphisms (SNPs) (SNP1 T151C, SNP2 Α180G, SNP3 G318A) for each animal. Statistical analyses revealed that SNP2 Α180G in heterozygosity (AG) as well as SNP3 G318A in homozygosity (AA) are correlated with susceptibility to canine leishmaniosis.
