Rabbits are susceptible to infection by different species of the genus Mycobacterium. Particularly, development specific lesions and isolation Mycobacterium avium subsp. paratuberculosis, both subspecies M. complex, has been reported in wildlife conditions. Although, rabbit meat production worldwide is 200 million tons per year, microbiological data on this source lacking more specifically reports mycobacterial presence industrially reared for human consumption have not published. To end, we sought mycobacteria histopathological methods paying special attention paratuberculosis rabbits from commercial rabbitries North East Spain. was detected either culture or PCR. However, 15.15 % (10/66) hominissuis 1.51 (1/66) gut associated lymphoid tissue sampled animals PCR, whereas caecal contents were negative. 9 (6/66) presented gross suggestive activation, 6 (4/66) granulomatous 3 (2/66) contained acid fast bacilli. Mycobacterial samples achieved, although colonies Thermoactinomycetes sp. identified 16s rRNA sequencing animals. Apparently healthy farmed that go slaughter may carry tissue.
