Nonantibiotic strategies are urgently needed to treat acute drug-resistant bacterial pneumonia. Recently, nanomaterial-mediated bacterial cuproptosis has arisen widespread interest due to its superiority against antibiotic resistance. However, it may also cause indiscriminate and irreversible damage to healthy cells.

This review discusses the chemical properties, synthesis and detection, and biological functions of a molecular group of cis-2-unsaturated fatty acids, containing fatty acid carbon chains of various lengths and cis double-bond configurations, known as the diffusible signaling factor family (DSFF). Early postulation of the conserved nature of the DSFF among Gram-negative bacteria have now been challenged by the latest evidences that unraveled their presence in a various other distinct microorganisms. Over the last decade, a significant depth and breadth of understanding has been made on the multifaceted functions of DSFFs among bacteria, and their interactions with evolutionarily divergent fungi, plants insects and small animals.

This cell-cell signaling is necessary for intra- and interspecies behaviors such as virulence and biofilm formation. While QS has been extensively studied in bacteria, little is known about cell-cell communication in archaea.

Burkholderia contaminans SK875, a member of Burkholderia cepacia complex (Bcc), are known to cause lung infections in cystic fibrosis patients. To gain deeper insights into its quorum sensing (QS)-mediated pathogenicity, we employed a transposon (Tn) insertion-based random mutagenesis approach. A Tn mutant library comprising of 15,000 transconjugants was generated through conjugation between wild-type (WT) recipient B.
