The development of treatment strategies for periodontitis that maximise the
effectiveness of antibiotics is highly desirable. Azithromycin is proving to be an effective antibiotic
for treatment of refractory periodontitis which works by binding to the outer membrane of Gramnegative bacteria and subsequently inhibits protein synthesis. Lactoferrin is a membrane-active
host antimicrobial protein and so the objective of this study was to determine whether the effect
of azithromycin (AZM) against example periodontopathogens (Porphyromonas gingivalis and
Tannerella forsythia) could be potentiated by lactoferrin. (Copied from article).
