Mycobacterium avium subsp. hominissuis Infection in Swine Associated with Peat Used for Bedding

Figure 1

An unrooted tree showing genetic relationship between isolates of Mycobacterium avium subsp. hominissuis originating from peat, sawdust, and lymph nodes from slaughtered pigs in Norwegian herds. The dendrogram is based on eight-locus MLVA analysis [17]. The tree was created in BioNumerics 6.1, using categorical data and the unweighted pair group method with arithmetic mean (UPGMA). Mycobacterium avium subsp. avium ATCC 25291 was used as a reference strain. The different MLVA profiles are named A–P.
