""\\"Abstract. INTRODUCTION:. . Recent findings propose that Mycobacterium avium subsp. paratuberculosis (MAP) infection could act as risk factor in favoring multiple sclerosis (MS) progression. SLC11A1 is a gene associated with mycobacterial survival in the host and it may be involved in the induction and maintenance of autoimmune disease.. METHODOLOGY:. . In this preliminary study, 100 MS patients and 100 healthy controls (HCs) from Sardinia were enrolled. Eight single nucleotide polymorphisms (SNPs) in the SLC11A gene were searched by PCR RFLP-genotyping. IS900 specie specific PCR was undertaken to search for MAP presence. Indirect ELISA was performed to asses if MS patients displayed a stronger humoral response against MAP2694 protein compared to the HCs.. RESULTS:. . Only rs2276631 SNP was associated with MS. MAP DNA was detected in 23 out of 100 MS patients (23%) and in 7 out of 100 HCs (7%). A strong humoral response against MAP2694 protein was detected in 36% of MS patients and only in 3% of HCs. A correlation between ELISA sero-positivity and the rs2276631 SNP was also found.. CONCLUSION:. . Our preliminary results suggest that the Sardinian population might be prone to develop autoimmune disease due to polymorphisms in immunomodulating the SLC11A1 gene, which is important in the immune response against intracellular bacteria such as MAP.\\"""
