In this study, chemically synthesized tick defensins and cathelicidin-derived mammalian peptides were used to investigate the activity spectrum against Borrelia garinii and symbiotic Stenotrophomonas maltophila. Synthetic tick defensins showed antimicrobial activity against Staphylococcus aureus but not B. garinii and S. maltophila. Mammalian peptides which have cationic property similar to tick defensins, showed antimicrobial activity similar to tick defensins. The antimicrobial peptides in ticks and mammalian hosts have common characteristics against microbial invasion in the innate immune system.
