Bacterial biofilms can be viewed as a specific type of persistent bacterial infection. After initial invasion, microbes can attach to living and non-living surfaces, such as prosthetics and indwelling medical devices, and form a biofilm composed of extracellular polysaccharides, proteins, and other components. In hosts, biofilm formation may trigger drug resistance and inflammation, resulting in persistent infections. The clinical aspects of biofilm formation and leading strategies for biofilm inhibitors will be discussed in this mini-review.

An Elizabethkingia meningoseptica infection was detected at the end stage of a patient with T-cell non-Hodgkin’s lymphoma. The complete genome of this isolated strain, FMS-007, was generated in one contig with a total size of 3,938,967 bp. A preliminary screening indicated that the genome contains drug resistance genes to aminoglycosides and β-lactams. A clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated proteins (CRISPR/Cas) system with 16 direct repeats and 15 spacers was identified.
