Antimicrobial activities of Agave fructans against multi-resistant and biofilm-producing Staphylococcus aureus isolated from bovine mastitis

Bovine mastitis is an emerging disease that causes large economic losses. Staphylococcus aureus its main etiological agent, is multi-resistant to antimicrobials and produces biofilm. The objective of this study was to investigate the effect of Agave fructans (AF), a type of prebiotic, on multi-resis...

Description
Summary:Bovine mastitis is an emerging disease that causes large economic losses. Staphylococcus aureus its main etiological agent, is multi-resistant to antimicrobials and produces biofilm. The objective of this study was to investigate the effect of Agave fructans (AF), a type of prebiotic, on multi-resistant and biofilm-forming isolates of S. aureus . Ten isolates of S. aureus from bovine subclinical mastitis previously characterized as highly resistant to antimicrobials and biofilm formers were used in this study. The growth kinetics of S. aureus in the presence of AF was evaluated by the Baranyi and Roberts microbial growth model using the DMFit program. The antibacterial activity of AF against S. aureus was studied by the well-diffusion method and the effect on biofilm formation by the crystal violet method. All assays were performed in triplicate for each isolate and an ANOVA with Tukey’s post hoc was performed considering p
