El genotipo de Mycobacterium bovis mayoritario en la Argentina lo es también en las islas Británicas: la tuberculosis bovina provino de Gran Bretaña? / [The genotype of the principal Mycobacterium bovis in Argentina is also that of the British Isles: did bovine tuberculosis come from Great Britain?]

Bovine tuberculosis is a highly prevalent animal disease in Argentina. In this work evidence was obtained showing that a major Mycobacterium bovis group in Argentina had been introduced with the bovine bulls imported from the United Kingdom at the end of the XIX century. This evidence came from two sources: historical, obtained by bibliographical references, and from laboratory results, using a molecular typing method called spoligotyping. These strains are also present in other countries that introduced cattle from the same origin.
