Nylon membrane after hybridization between the labeled probe and the DNA from C. perfringens control strains used in this study (AHL 311 and ATCC 13124); positive hybridization signals were observed for AHL 311 only. Red square is showing the DNA demonstrating a positive hybridization signal.

Article Snippet: Three distinct DNA extractions were performed: two DNA extractions from the cpepositive C. perfringens AHL 311 control strain that yielded 27.9 ng/μL and 33.3 ng/μL of DNA and one DNA extraction from the cpe-negative ATCC 13124 C. perfringens reference strain yielding 28.0 ng/μL of DNA.
