Metal-Binding Properties of Bacitracin A
Bacitracin A is a cyclic dodecapeptide antibiotic produced by Bacillus licheniformis. Bacteriocidal activity requires the presence of divalent metal cations such as Zn('2+). The metal-bacitracin A complex binds to bactoprenylpyrophosphate, a lipid intermediate required for cell wall biosynthesis …

Effects of subtherapeutic doses of antibiotics on poultry intestinal bacteria
… in species associated with antibiotic (zinc bacitracin, 55 ppm) treatment. The ileal flora also was predominantly lactobacilli (average 75% of the flora). The most common lactobacilli from the turkey intestinal tract were several previously undescribed Lactobacillus species followed by L. …

Efficacy of exogenous phytase and protease enzymes on performance and gastrointestinal health in broiler chickens
… in combination, or in combination with AGP, zinc bacitracin on performance and intestinal morphology in broilers was tested. Broilers were fed a diet containing nutrients at recommended levels (positive control, PC) with no enzyme supplementation or a diet with lower nutrient density than PC, …
