In this study, antimicrobial-resistance patterns were analyzed in Escherichia coli isolates from raw (RW) and treated wastewater (TW) of two wastewater treatment plants (WWTPs), their marine outfalls (MOut), and mouth of the Vistula River (VR). Susceptibility of E. coli was tested against different classes of antibiotics. Isolates resistant to at l...
In this study, species distribution and antimicrobial susceptibility of cultivated Pseudomonas spp. were studied in influent (INF), effluent (EFF), and marine outfall (MOut) of wastewater treatment plant (WWTP). The susceptibility was tested against 8 antimicrobial classes, active against Pseudomonas spp.: aminoglycosides, carbapenems, broad-spectr...
Until recently, the data on the diversity of the entire microbial community from the Baltic Sea were relatively rare and very scarce. However, modern molecular methods have provided new insights into this field with interesting results. They can be summarized as follows. (i) Although low salinity causes a reduction in the biodiversity of multicellu...
The global crisis of the Coronavirus disease-2019 (COVID-19) pandemic has caused an enormous burden not only on the health, social, and economic sectors but also on many essential municipal services. Water distribution and wastewater management have faced increasing uncertainty due to the possible transmission of Severe Acute Respiratory Syndrome C...
Antimicrobial resistance (AMR) is one of the largest global concerns due to its influence in multiple areas, which is consistent with One Health’s concept of close interconnections between people, animals, plants, and their shared environments. Antibiotic-resistant bacteria (ARB) and antibiotic-resistance genes (ARGs) circulate constantly in variou...
Marine nitrogen cycle ultimately depends on the biological responses of oceanic microbial communities. It indirectly regulates primary production and influences the strength of the biological pump, which contributes to the oceanic uptake of atmospheric carbon dioxide (CO2). As the microbial community structure and functional capacities remain under...
In the high-throughput sequencing (HTS) era, a metabarcoding technique based on the bacterial V3–V4 hypervariable region of 16S rRNA analysis requires sophisticated bioinformatics pipelines and validated methods that allow researchers to compare their data with confidence. Many commercial laboratories conduct extensive HTS analyses; however, there...
Konsorcjum Mikrobiologów Morza (MIMO) zostało utworzone w dniu 09.07.2021 roku przez Uniwersytet Gdański, Instytut Oceanologii Polskiej Akademii Nauk w Sopocie, Politechnikę Gdańską, oraz Morski Instytut Rybacki - Państwowy Instytut Badawczy w Gdyni. Dnia 28.01.2022 roku do MIMO przystąpiły także: Akademia Pomorska w Słupsku oraz Gdański Uniwersyte...
COVID-19 - wywołany przez wirusa SARS-CoV-2, prowadzący m.in. do ostrej niewydolności oddechowej, spowodował kryzys w służbie zdrowia i istotne implikacje społeczno-gospodarcze. Główną drogą przenoszenia SARS-CoV-2 jest droga kropelkowa, czyli aerozole z dróg oddechowych, generowane przez kaszel, kichanie i mówienie. Zakażenie SARS-CoV-2 może nie t...
Environmental stressors are assessed through methods that quantify their impacts on a wide range of metrics including species density, growth rates, reproduction, behaviour and physiology, as on host-pathogen interactions and immunocompetence. Environmental stress may induce additional sublethal effects, like mutations and epigenetic signatures aff...
Microcystins (MCs) and nodularin (NOD), the hepatotoxic nonribosomal peptides (NRPs) produced by cyanobacteria, are considered as natural pollutants of many aquatic ecosystems. Removal of the toxins proceeds mainly through biodegradation and/or photolysis. In this study, microbial degradation of NOD and other NRPs produced by Nodularia spumigena wa...
Purpose
Mercury speciation in sediments is linked to environmental conditions and processes. Domination of particular mercury species depends on its source, displays considerable seasonal behavior, and may be further modified due to oxygen levels, icing conditions, or the input of fresh organic matter. The purpose of this study was to examine the c...
The aim of this study was to analyze the occurrence of sulfonamide-resistance genes (sul1-3) and other genetic elements as antiseptic resistance gene (qacEΔ1) and class-1 and class-2 integrons (int1-2) in the upper layer of substrate and in the effluent of microcosm constructed wetlands (CWs) treating artificial wastewater containing diclofenac and...
In this study, the susceptibility to erythromycin (E) and to trimethoprim/sulfamethoxazole (SXT) among isolates of Enterococcus spp. and Escherichia coli was tested, respectively. Both fecal indicators were detected and isolated from raw (RW) and treated wastewater (TW) as well as from samples of activated sludge (AS) collected in a local wastewate...
In this study removal rate of six antimicrobial compounds (belonging to folate pathway inhibitors and macrolides class) was analyzed in processes of local Wastewater Treatment Plant (WWTP) together with susceptibility patterns of Erythromycin (E) resistant Enterococcus spp. and trimethoprim/ Sulfamethoxazole (SXT) resistant Escherichia coli. Accord...
The presence of antibiotic substances in the marine environment is of high concern since it potentially accelerates widespread bacterial antibiotic resistance and may have negative effects on bacteria responsible for organic matter mineralization and processes of nitrification and denitrification. Thus concentration of the antibiotic residues and i...
The resistance of 49 strains of bacteria isolated from surface Baltic Sea waters to 11 antibiotics was analyzed and the resistance of selected strains to three metal ions (Ni2+, Mn2+, Zn2+) was tested. Most isolates belonged to Gammaproteobacteria (78%), while Alphaproteobacteria (8%), Actinobacteria (10%), and Bacteroidetes (4%) were less abundant...

A novel microbiological mutagenicity assay, based on bioluminescence of a marine bacterium Vibrio harveyi mutant strain, potentially suitable for monitoring and assessment of mutagenic pollution of marine environment, has been described recently. Here, we tested the use of this assay, in combination with either mussels (Mytilus sp.) or semipermeabl...
Mutagenic pollution of the natural environment, including marine waters, is a very serious ecological problem. However, since chemical mutagens usually occur and act at low concentrations, their detection and identification is technically difficult, laborious and time-consuming. Therefore, preliminary detection of mutagenic pollution is commonly ba...
Recently, we have developed a novel assay designed for detection of mutagenic pollution of the marine environment. This assay is based on the use of a series of genetically modified strains (named BB7, BB7M, BB7X and BB7XM) of a marine bacterium Vibrio harveyi. Sensitivity of the V. harveyi mutagenicity assay was found to be similar to, or even som...
