The characterisation of the antimicrobial activity of six antibacterial peptides, isolated from the venom of the neotropical wandering spider Cupiennius salei is reported. The peptides have a molecular weight, determined by electrospray ionisation-mass spectrometry, between 3 to 4 kDa, and they consist of approximately 26 to 35 amino acids. All six peptides lack cysteines but they are rich in lysine. Peptide 1 is very closely related to CSTX-4, a known bactericidal and insecticidal toxin from the venom of Cupiennius salei.
