Natural transformation allows transfer of SCCmec-mediated methicillin resistance in Staphylococcus aureus biofilms

Nature Communications, 2022
SCCmec is a large mobile genetic element that confers resistance to β-lactam antibiotics in methicillin-resistant Staphylococcus aureus. Here, the authors show that biofilm growth conditions enhance the efficiency of natural transformation in S.

β-Glucan-Producing Pediococcus parvulus 2.6: Test of Probiotic and Immunomodulatory Properties in Zebrafish Models

Frontiers in Microbiology, 2018
Lactic acid bacteria synthesize exopolysaccharides (EPS), which could benefit the host’s health as immunomodulators. Furthermore, EPS could protect bacteria against gastrointestinal stress, favoring gut colonization, thus protecting the host against ...
