ABSTRACT:The importance of paratuberculosis, an infectious bowel disease of ruminants, and Crohn's disease, a type of inflammatory bowel disease in humans with suspected links with Mycobacterium avium subsp. paratuberculosis, is evident from the steadily increasing number of publications on these topics. Data from the Web of Science databases were analysed by authors, institutions, countries and funding agencies, involved in research. A summary of the descriptive data for the most frequently cited publications are presented here.
