UTP25 and bacterial infectious disease: In addition, the expression levels of known D. melanogaster AMP genes, including attacin A (attA), attacin B (attB), diptericin (dpt), defensin (def), drosocin (dro), cecropin A1 (ce-A1), and cecropin A2 (ce-A2) were also examined together with wap gene in t6 experimental and control groups under normal culture conditions and bacterial infection by qRT-PCR.
