Encrypted antimicrobial peptides from proteins present in the plasma of the millipede Rhinocricus sp.

Millipedes are among the most diverse and abundant arthropods in terrestrial environments. However, little is known about their innate immune response against invading pathogenic microorganisms, which is very intriguing considering that the evolutionary success of millipedes is largely due to this complex and primitive defense system, since it allowed them to colonize a wide variety of microhabitats characterized by their high microbial proliferation. Accordingly, the aim of the present work was to determine the presence of antimicrobial peptides in the hemolymph of the millipede Rhinocricus sp.

Sarconesin II, a New Antimicrobial Peptide Isolated from Excretions and Secretions.

Antibiotic resistance is at dangerous levels and increasing worldwide. The search for new antimicrobial drugs to counteract this problem is a priority for health institutions and organizations, both globally and in individual countries. blowfly larval excretions and secretions (ES) are an important source for isolating antimicrobial peptides (AMPs).
