Effect of azithromycin on a red complex polymicrobial biofilm

Abstract: Azithromycin has recently gained popularity for the treatment of periodontal disease, despite sparse literature supporting efficiency in treating periodontal bacterial biofilms. The aim of this study was to evaluate the effect of azithromycin on biofilms comprised of Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia in comparison to an amoxicillin and metronidazole combination. P. gingivalis W50, T. denticola ATCC35405, and T. forsythia ATCC43037 grown under anaerobic conditions at 37°C w… Show more

“…Ong and co-workers [46] evaluated the efficacy of AZM on mono- and polymicrobial biofilm formations consisting of P. gingivalis , T. denticola, and T. forsythia in comparison to AMX + MTZ in combination in vitro. The antibiotics were dispersed using deionized water and final antibiotic concentrations in the range between 0.01–100 mg/L were tested in the respective supernatants of the microbial cultures.…”

“…The metabolic activity was reduced 84% through AMX + MTZ whereas only by 17% through AZM [65]. The MIC and MBIC of AMX + MTZ in combination was found to be almost 10-fold lower than the one of AZM [46].…”

“…A determinação da concentração mínima de inibição de biofilme (CMIB) e da concentração mínima de erradicação de biofilme (CMEB) foi realizada pela técnica de CBD (ONG et al, 2017;KANNAPPAN et al, 2017;BENTHALL et al, 2015), que foi constituída por 3 etapas:…”

“…Cada tampa contendo os biofilmes previamente formados foi transferida para a nova microplaca contendo os diferentes antimicrobianos. Cada placa foi incubada a 37ºC por 24 horas, sem agitação (Ong et al, 2017;Kannappan et al, 2017). A concentração equivalente ao poço onde não foi observado crescimento bacteriano através da turbidez do meio foi considerada como concentração mínima de inibição de biofilme (CMIB).…”
