The Deciphering of Growth-Dependent Strategies for Quorum-Sensing Networks in .

is recognized as a significant cause of morbidity and mortality among nosocomial pathogens. In respiratory infections, acts not only as a single player but also collaborates with the opportunistic fungal pathogen . This study introduced a QS molecule portfolio as a potential new biomarker that affects the secretion of virulence factors and biofilm formation.

Killing Effect of FZB42 on a pv. (Xcc) Strain Newly Isolated from Cabbage Convar. (L.): A Metabolomic Study.

The potential use of FZB42 for biological control of various phytopathogens has been documented over the past few years, but its antagonistic interactions with xanthomonads has not been studied in detail. Novel aspects in this study consist of close observation of the death of pv. cells in a co-culture with FZB42, and quantification of lipopeptides and a siderophore, bacillibactin, involved in the killing process.

Bringing SEM and MSI Closer Than Ever Before: Visualizing and Infection in the Rat Lungs.

A procedure for processing frozen rat lung tissue sections for scanning electron microscopy (SEM) from deeply frozen samples initially collected and stored for matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) was developed. The procedure employed slow thawing of the frozen sections while floating on the surface and melting in a fixative solution. After the float-washing step, the sections were dehydrated in a graded ethanol series and dried in a critical point dryer.
