Effects of growth in the presence of subinhibitory concentrations of dicloxacillin on Staphylococcus epidermidis and Staphylococcus haemolyticus biofilms

Article Abstract:

The changes in the physiology of CoNS triggered by biofilm formation in the presence of a low concentration of dicloxacillin, a major antibiotic used to treat staphylococcal infections in Portugal, is evaluated. The oxygen contents were decreased in Staphylococcus epidermidis, whereas these parameters were increased in Staphylococcus haemolyticus and also the increase in resistance to several antibiotics were observed for the cells within biofilms formed in the presence of dicloxacillin

Streptococcus thermophilus and its biosurfactants inhibit adhesion by Candida spp. on silicone rubber

Article Abstract:

A study was conducted on the adhesion of Candida tropicalis and Candida albicans strains to silicone rubber with and without the presence of the biosurfactant-releasing dairy isolate Steptococcus thermophilus. Results show that the adhering bacteria's biosurfactant release inhibit yeast adhesion. Mid-exponential and early-stationary-phase bacteria had the highest amounts of released biosurfactants.

Influence of biosurfactants from probiotic bacteria on formation of biofilms on voice prostheses

Article Abstract:

The biofilms were formed on the voice protheses that were trained beforehand with biosurfactants procured from probiotic bacteria called lactococcus lactis 53 and streptococcus thermophilus A in a hypothetical throat model. This study indicates the existence of a policy, which ensures the elongated lifespan of voice protheses.
