New strategies must be explored by the scientific community in order to create new treatment alternatives. Animal venoms are a good source for antimicrobial peptides (AMPs), which are excellent candidates for new antimicrobial drug development. Cathelicidin-related antimicrobial peptides (CRAMPs) from snake venoms have been studied as a model for the design of new antimicrobial pharmaceuticals against bacterial infections.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In this study we present an 11 amino acid-long peptide, named pseudonajide, which is derived from a\n                      <jats:italic>Pseudonaja textilis<\/jats:italic>\n                      venom peptide and has antimicrobial and antibiofilm activity against\n                      <jats:italic>Staphylococcus epidermidis<\/jats:italic>\n                      . Pseudonajide was selected based on the sequence alignments of various snake venom peptides that displayed activity against bacteria. Antibiofilm activity assays with pseudonajide concentrations ranging from 3.12 to 100\u2009\u03bcM showed that the lowest concentration to inhibit biofilm formation was 25\u2009\u03bcM.
