title: Polymorphism of the PE domain of PE/PE_PGRS sequences in clinical isolates of Mycobacterium bovis in Mexico.
abstract: Polymorphism of the PE domain of PE/PE_PGRS sequences was studied in Mycobacterium bovis isolates from different Mexican states. Samples were analyzed by spolygotyping and RFLP using IS6110 and a 235-bp fragment of the PE domain of PE/PE_PGRS as probes. With the PE probe, three different genotypes were observed, one being predominant in all states. These results confirm the high conservation of the PE domain and suggests a potential role for PE sequence as a stable genetic marker for bovine tuberculosis.
