Antibiotics and antibiotic resistant bacteria enter wastewater treatment plants (WWTPs), an environment where resistance genes can potentially spread and exchange between microbes. Several antibiotic resistance genes (ARGs) were quantified using qPCR in three WWTPs of decreasing capacity located in Helsinki, Tallinn, and Tartu, respectively: sulphonamide resistance genes (sul1 and sul2), tetrac...

In this study, we formulate the concept of “mining maximal-size frequent subgraphs” in the challenging domain of visual data (images and videos). In general, visual knowledge can usually be modeled as attributed relational graphs (ARGs) with local attributes representing local parts and pairwise attributes describing the spatial relationship between parts. Thus, from a practical perspective, su...

The global widespread use of antimicrobials and accompanying increase in resistant bacterial strains is of major public health concern. Wastewater systems and wastewater treatment plants are considered a niche for antibiotic resistance genes (ARGs), with diverse microbial communities facilitating ARG transfer via mobile genetic element (MGE). In contrast to hospital sewage, wastewater from othe...

The conversion of cattle manure into biogas in anaerobic digestion (AD) processes has been gaining attention recent years. However, antibiotic consumption continues to increase worldwide, which is why antimicrobial concentrations can be expected rise and digestate. This study examined the long-term synergistic effects antimicrobials on manure. prevalence resistance genes (ARGs) changes microbia...

The main objective of this review is to evaluate the performance constructed wetlands (CWs) used reduce antibiotic-resistant genes (ARGs) during sewage treatment. To accomplish objective, statistical and correlation analyses were performed using published data determine influence operational design parameters on ARG reduction in CWs. effects parameters, such as different CW configurations, seas...

The effluents of wastewater treatment plants (WWTPs) are major contributors nutrients, microbes—including those carrying antibiotic resistance genes (ARGs)—and pathogens to receiving waterbodies. effect the effluent a small-scale activated sludge WWTP treating municipal on composition and abundance microbial community as well resistome in sediment water stream river was studied using metagenome...

Abstract The perennial ice-covered lakes of the Antarctic McMurdo Dry Valleys harbour oligotrophic microbial communities that are separated geographically from other aquatic systems. Their microbiomes include planktonic microbes as well lift-off mat emerge ice. We used ShortBRED protein family profiler to quantify antibiotic resistance genes (ARGs) metagenomes mats emerging ice and filtered wat...
