Abstract:
... Pathogenic Aeromonas veronii results in great healthy and economic losses in fishes and human. The multiple drug tolerance of bacterial persister is the major cause for recurrent infections. Ubiquitous RNA-binding protein Hfq is liable for antibiotic tolerance and persisiter production. We showed that the hfq deletion in A. veronii retarded the growth, reduced the tolerances to diverse antibiotics ...

Abstract:
... Epidemiological data suggest that previous infections can alter an individual's susceptibility to unrelated diseases. Nevertheless, the underlying mechanisms are not completely understood. Substantial research efforts have expanded the classical concept of immune memory to also include long‐lasting changes in innate immunity and antigen‐independent reactivation of adaptive immunity. Collectively, ...

Abstract:
... Hosts can alter their strategy towards pathogens during their lifetime; that is, they can show phenotypic plasticity in immunity or life history. Immune priming is one such example, where a previous encounter with a pathogen confers enhanced protection upon secondary challenge, resulting in reduced pathogen load (i.e., resistance) and improved host survival. However, an initial encounter might als ...

Abstract:
... Bacterial persisters (defined as dormant, non-dividing cells with globally reduced metabolism) are the major cause of recurrent infections. As they neither grow nor die in presence of antibiotics, it is difficult to eradicate these cells using antibiotics, even at higher concentrations. Reports of metabolites (which help in waking up of these inactive cells) enabled eradication of bacterial persis ...
