“…Among the Gram-positive species, only those that are in any case known to be easily killed by AMPs in general, such as Bacillus megaterium, Bacillus subtilis and Listeria monocytogenes, are affected, albeit at higher concentrations [10,24,26,50,51]. PR-39 was found to be active against drug-susceptible and multi-drug-resistant clinical isolates of Mycobacterium tuberculosis [52], while Bac5 and Bac7 were reported to be active against various species of Brucella [53] as well as against spirochetes, such as Leptospira but not Borrelia species [54].…”
