About this Research Topic
Environmental antibiotic and antibiotic resistance gene contamination is increasing due to human and animal use of these compounds. Various anthropogenic sources, such as wastewater treatment plant effluents and biosolids, reclaimed water, animal manures, and farm runoff, are responsible for the diffusion of antibiotic residues, resistant bacteria and genes in soil and water ecosystems. An ecological and multidisciplinary ‘One Health’ approach including humans, animals and their specific environments is necessary for understanding antibiotic overall impacts and assessing effective mitigation measures.
Several ecological aspects regarding the effects of antibiotics and homeostatic response of natural microbial communities need to be clarified. Microorganisms interact in both intra- and inter-species relationships, modulated by site-specific environmental conditions (e.g. temperature, humidity, multi-contamination), which make each ecosystem a unique one. Consequently, the effects of antibiotics (including at minimum selective concentrations and at minimum inhibitory concentrations) on natural microbial communities can be different and strongly linked to the bacterial resistance and resilience responses.
Environmental microorganisms not only play a key role in fundamental ecological processes such as biogeochemical cycling and organic contaminant degradation, but also in antibiotic removal and antibiotic resistance spread. Antibiotics can persist in soil or water depending on their inherent physic-chemical properties (e.g. water solubility, lipophilicity), site-specific environmental factors (e.g. temperature, light, pH) and the presence and activity of microorganisms able to biodegrade them. Antibiotic occurrence in the environment can compromise or change microbial community structure and activities in different ways. Microorganisms interact in both intra- and inter-specific relationships, modulated by site-specific environmental conditions (e.g. temperature, humidity, multi-contamination), which make each ecosystem a unique one. Consequently, the effects of antibiotics on ecosystems can be variously and strongly linked to the bacterial resistance and resilience responses to their occurrence. This Special Issue addresses a wide range of microbial ecology aspects of antibiotic occurrence, persistence, effects and resistance spread in natural microbial communities, including the plant microbiome.
This Research Topic will collect studies on the effects of antibiotics on natural microbial communities and all the biotic and abiotic factors which influence antibiotic persistence and bacterial resistance.
