          Abstract

          In 2003 Mycobacterium pinnipedii was described as responsible for producing tuberculosis (TB) in living otariid pinnipeds from Argentina and Australia. It is the only member of marine origin within the Mycobacterium tuberculosis Complex (MTBC), which also affects other domestic and wild mammals, and humans. Based on several pre-Columbian records of human tuberculosis in South America, in 2010-2011 a new hypothesis about the origin of this zoonosis through otariid pinnipeds arose. In 2014, this hypothesis was confirmed based on the study of ancient DNA from three mummies (700-1,000 years BP) of the Chiribaya culture (Peru). Since there were no records of TB bone lesions in zooarchaeological samples of otariid pinnipeds from South America and the rest of the world, our study aimed at examining zooarchaeological samples of pinnipeds from coastal sites of the Beagle Channel (Tierra del Fuego, Argentina), being the oldest Túnel I (6,400-4,300 years BP). A total of 4,138 vertebrae were analyzed, of which 0.46% showed lesions compatible with TB. In addition, we propose a new hypothesis on possible mechanisms of Mycobacterium pinnipedii dissemination that would explain the transmission routes to the different otariid pinniped species of the Southern Hemisphere. Mycobacterium pinnipedii is one of the most aggressive mycobacteria of the MTBC and of high risk for humans.

          En 2003 fue descripto Mycobacterium pinnipedii como responsable de producir tuberculosis (TB) en pinnípedos otáridos de Argentina y Australia. Esta especie es la única de origen marino del Mycobacterium tuberculosis Complex (MBTC), que afecta también a otros mamíferos domésticos, silvestres y humanos. Debidoa numerosos registros de tuberculosis humana precolombina en Sudamérica, surge en 2010-2011 una nueva hipótesis sobre el origen de esta zoonosis a través de los pinnípedos otáridos. En 2014 esta hipótesis fue confirmada a través de estudios de ADN antiguo de tres momias (700-1.000 años AP) de la cultura Chiribaya (Perú). En virtud de no existir registros de TB ósea en muestras zooarqueológicas de pinnípedos de Sudamérica y del resto del mundo, nuestro estudio tuvo como finalidad examinar muestras zooarqueológicas de pinnípedos otáridos de sitios costeros del Canal Beagle (Tierra del Fuego, Argentina), siendo el más antiguo Túnel I (6.400-4.300 años AP). Se analizó un total de 4.138 vértebras, de las cuales el 0,46% mostró lesiones compatibles con TB. Complementariamente, se propone una nueva hipótesis sobre posibles mecanismos de diseminación de Mycobacterium pinnipedii, planteando las posibles rutas de transmisión a las diferentes especies de pinnípedos otáridos del Hemisferio Sur. Mycobacterium pinnipedii es una de las micobacterias más agresivas del MBTC y de mayor riesgo para los humanos.
