Detection of a group II intron without an open reading frame in the alpha-toxin gene of Clostridium perfringens isolated from a broiler chicken.

A DNA insertion of 834 bp, designated CPF-G2Im, was identified within the alpha toxin gene (cpa) of Clostridium perfringens strain CPBC16ML, isolated from a broiler chicken. Sequence analysis of CPF-G2Im indicated that it was integrated 340 nucleotides downstream of the start codon of cpa. However, the insertion did not abolish the phospholipase C and… (More)
