Description

Erythromycin B, EvoPure® is a highly purified form of erythromycin B,  an active component of the macrolide antibiotic, erythromycin. Erythromycin is composed of sevaral related components including erythromycin A, B, C, and D. Erythromycins A and B have similar MICs with A being slightly more active than B. Erythromycins C and D have slightly less than half the activity of erythromycins A and B. Erythromycin A contains a hydroxyl group at C12 that erythromycin B lacks. This minor difference accounts for the ability of erythromycin B to retain much of its antibacterial activity in an acidic environment where erythromycin A does not.
