Figure 3: Specific polymerase chain reaction amplification for P. thornei (288 bp) and P. neglectus (144bp) from pure cultures using species-specific primers PTHO/PENG. DNA templates from the isolates Pt1, Pt2, Pt3, Pt4, Pn1, Pn2, Pn3, Pn4; Nc: negative control without DNA template; L: 1000-bp DNA molecular weight ladder.
