Table 1. Antibacterial assays of catestatin (bovine, bCAT and human, hCAT) and cateslytin (bovine, bCTL) against different S. aureus strains, compared to the cathelicidin antimicrobial peptide-18 (LL-37).

Antimicrobial peptides	MIC (µg/mL)
	S. aureus ATCC49775	S. aureus ATCC25923	S. aureus S1 (MRSA)	S. aureus S2 (MSSA)
bCAT	100 aA	100 aA	100 aA	115 bA
hCAT	125 aB	135 aB	130 aB	150 bB
bCTL	37 aC	40 aC	37 aC	45 bC
LL-37	30 aD	30 aD	30 aC	35 bC

Results are presented as MIC (µg/mL) of each peptide against four S. aureus strains. Values represent the means of the triplicate (n = 3) wells. Means with same letters are not significantly different (p<0.05). Small letters (a, b, c) represents significance between different S. aureus strains, while capital letters (A, B, C) represent significantly difference between peptides.
