Abstract

Microbial infections still represent one of the major causes of mortality and morbidity worldwide. Irrational usage of antimicrobials has lead to increased resistance, causing clinical, social and economical disabilities. Therefore, one of the major challenges of scientists is to develop novel alternative methods to handle infections and reduce resistance and other side effects produced by the actual therapies. The aim of this book is to offer a perspective on novel approaches to handle infections by using naturally-derived products in order to modulate the virulence of pathogens, without the risk of developing resistance. We intend to highlight the utility of microbial, vegetal and animal–derived compounds with potential antimicrobial activity by exploiting their effect on microbial virulence. Furthermore, this book aims to reveal the potential to assimilate recent bio-technological findings, like the usage of nanotechnology as efficient shuttles for stabilizing, improved targeting and the controlled release of natural products in order to efficiently fight infections.

Abstract

Cancer survival rates and successful organ transplantation in patients continues to increase due to improvements in early diagnosis and treatments. Since immuno-suppressive therapies are frequently used, the mortality rate due to secondary infections has become an ever-increasing problem. Opportunistic fungal infections are probably the deadliest threat to these patients due to their difficult early diagnosis, the limited effect of antifungal drugs and the appearance of resistances. In recent years, a considerable effort has been devoted to investigating the role of many virulence traits in the pathogenic outcome of fungal infections. New virulence factors (hypoxia adaptation, CO2 sensing, pH regulation, micronutrient acquisition, secondary metabolites, immunity regulators, etc.) have been reported and their molecular mechanisms of action are being thoroughly investigated. The recent application of gene-editing technologies such as CRISPr-Cas9, has opened a whole new window to the discovery of new fungal virulence factors. Accurate fungal genotyping, Next Generation Sequencing and RNAseq approaches will undoubtedly provide new clues to interpret the plethora of molecular interactions controlling these complex systems. Unraveling their intimate regulatory details will provide insights for a more target-focused search or a rational design of more specific antifungal agents. This Special Issue is show significant discoveries, proofs of concept of new theories or relevant observations in fungal pathogenesis and its regulation.
