Activity of partially purified preparations of aureocins 4181 and A70 against mastitic pathogens in broth

Mastitic pathogens	BU/mLa required for inhibition by		Effectiveness
	Aureocin A70	Aureocin 4181
S. aureus 4801	80	20	4
S. aureus 4802	80	20	4
S. aureus 4807	80	20	4
S. aureus 4819	160	80	2
S. agalactiae 4810	640	320	2
S. agalactiae 4824	> 640	640	≥ 2
S. agalactiae 4828	640	320	2
S. agalactiae 4923	> 640	640	≥ 2

^aMeans of two independent experiments which gave identical results

The numbers represent the minimal BU/mL required to inhibit at least 50% of the bacterial growth, when compared with the control with no aureocin added
