Future studies will need to examine the potency of the antimicrobial peptide repertoire of additional species, especially in growth inhibition assays against B. dendrobatidis . The skin of a frog may have 10–20 antimicrobial peptides with different size, sequences, charges, hydrophobicity, tridimensional structures and spectrum of action, and this armament differs between frogs belonging to different families, genera, species or even subspecies, consequently, no two species with the same panoply of peptide antibiotics have yet been found . Secretions of amphibian skin glands contain numerous antimicrobial peptides that play a crucial role in the defense against microorganisms. The location of these glands on the surface of the animal makes them a useful model for in vivo studies of the relationships between the innate immune system and the natural flora. In the present study, two brevinin-1 peptides (Brevinin1 HYba1 and 2; B1 and B2 for ease) identified from the skin secretion of the frog Hydrophylax bahuvistara and their analogs (B1A1, B2A1, B1A2, B2A2) were tested against two multi host Gram-negative pathogens such as Pseudomonas aeruginosa and Vibrio vulnificus.

Antimicrobial peptides are active against a wide spectrum of pathogens, including multidrug-resistant bacteria, fungi, viruses and parasites. Thus, they are promising candidates for treatment of various skin infections, also infections caused by bacteria such as methicillin resistant Staphylococcus aureus and vancomycin resistant enterococci. Antimicrobial peptides due to their antimicrobial activity not only kill skin pathogens but also initiate a potent host response to skin infection. This response results in cytokine release, inflammation and in consequence leads to a cellular response. These features of AMPs are actively involved in maintaining of the skin barrier homeostasis. In the skin, both resident and infiltrating cells synthesize and secrete small peptides that demonstrate broad-spectrum antimicrobial activity against bacteria, fungi, and enveloped viruses. Antimicrobial peptides also act as multifunctional immune effectors by stimulating cytokine and chemokine production, angiogenesis, and wound healing.

In addition, association of AMPs with skin Antimicrobial peptides and the skin In recent years, hundreds of naturally occurring peptide antibiotics have been discovered based on their ability to inhibit the growth of microbial pathogens. These antimicrobial peptides (AMPs) participate in the innate immune response by providing a rapid first-line defence against infection. Despite these microbial threats, skin is surprisingly highly resistant against infections. Various studies in the last decade discovered a chemical cutaneous defense system based on the production of antimicrobial proteins.

The magainins are antimicrobial peptides that are found in the skin glands of amphibians, such as frogs.

Fundamental differences exist between prokaryotic and eukaryotic cells that may represent targets for antimicrobial peptides.These peptides are potent, broad spectrum antibiotics which demonstrate potential as novel therapeutic agents. Peptides can help ease inflammation, repair damaged skin, and even out skin tone.
