Abstract EN
Mycobacterium avium subsp.
hominissuis is an environmental bacterium causing opportunistic infections in swine, resulting in economic losses.
Additionally, the zoonotic aspect of such infections is of concern.
In the southeastern region of Norway in 2009 and 2010, an increase in condemnation of pig carcasses with tuberculous lesions was seen at the meat inspection.
The use of peat as bedding in the herds was suspected to be a common factor, and a project examining pigs and environmental samples from the herds was initiated.
Lesions detected at meat inspection in pigs originating from 15 herds were sampled.
Environmental samples including peat from six of the herds and from three peat production facilities were additionally collected.
Samples were analysed by culture and isolates genotyped by MLVA analysis.
Mycobacterium avium subsp.
hominissuis was detected in 35 out of 46 pigs, in 16 out of 20 samples of peat, and in one sample of sawdust.
MLVA analysis demonstrated identical isolates from peat and pigs within the same farms.
Polyclonal infection was demonstrated by analysis of multiple isolates from the same pig.
To conclude, the increase in condemnation of porcine carcasses at slaughter due to mycobacteriosis seemed to be related to untreated peat used as bedding.
