*2.4. CST as a Potential Therapy for Bacterial Diseases*

AMPs derived from CgA display antimicrobial activities by lytic effects at micromolar range against Gram-positive bacteria, filamentous fungi, and yeasts. Interestingly, CSTderived peptides can kill "superbugs" and more particularly *S. aureus* [44]. Considering the actions of CST on *E. coli*, it could be useful as a therapeutic target for the Gram-negative bacteria that cause many serious infections, including Cholera [45], *E. coli* [46], *Yersinia* [47], *Campylobacter* [48], *Legionella* [49], *Salmonella* [50], *Klebsiella* [51], *Pseudomonas* [52], *Francisella tularensis* [53], *Salmonella typhi* [54], and microbes associated with drug resistance [55–57], and CST might be used as a therapeutic target for the above diseases.
