Identification of new IS 711 copies in B. abortus B12, B16, B49 and B50 by Southern blot. The new IS711 copies found in field isolates and the additional IS711 present in 2308 and RB51 are indicated on the left. The IS711-nomenclature proposed by Ocampo-Sosa et al. (2008) and the fragment size are indicated on the right (note that x-08 fragment includes both the additional 2308 strain and 3a copies). The signals marked with an * correspond to IS other than IS711 which show cross-hybridization. Capital letters at the bottom indicate the RFLP IS711 AvaI-ClaI profile (Table 1).
