abstract         background and objective: paratuberculosis has been repeatedly reported from iranian ruminant herds. the extrem fastidious nature of mycobacterium avium subspecies paratuberculsos hinders genomic diversity studies of the pathogen. short sequence repeat analysis is one of the genome-based approches recently developed to overcome this difficulty. in this study we describe the app...
