Feedback mechanisms between interferons α and λ (IFNs) may be affected by single nucleotide polymorphisms (SNP) in interleukin 28B (IL-28B; IFN-λ3) promoter region and may influence cytomegalovirus (CMV) replication. We associated IL-28B SNPs with the risk of CMV replication after...

Biofilm-related infections account for at least 65% of all human infections, but there are no available antimicrobials that specifically target biofilms. Their elimination by available treatments is inefficient since biofilm cells are between 10- and 1,000-fold more resistant to conventional...
