“…Those results from the rivers with or without receiving wastewater compared together indicated that dominant bacterial phyla in river environments were influenced by antibiotic contaminations. Furthermore, the ubiquitous presence of Deltaproteobacteria, Epsilonproteobacteria, Clostridia, and Bacilli in sediment and water samples also indicated that the Liuxi River was contaminated by antibiotics, since Li suggested that Deltaproteobacteria, Epsilonproteobacteria, Clostridia, and Bacilli might be specifically associated with antibiotic containing environment (Li et al, 2011). In the present study, some phyla such as Synergistetes and TM7 were recently recognized, and were reported for the first time in river environments by using metagenome analysis.…”

Antibiotic resistance genes (ARGs) in the environment have paid great concern due to their health risk. We investigated antibiotics concentrations (tetracyclines, sulfonamides, and fluoroquinolones), ARGs abundances (tetracycline, sulfonamide, and plasmid-mediated quinolone resistance (PMQR) genes), and bacterial community composition in sediment and water samples in the Liuxi River, China. Antibiotics concentrations were determined by ultra-performance liquid chromatography-electrospray tandem mass spectrometry. ARGs abundances were quantified by a culture-independent method. Bacterial community composition was analyzed by metagenomic approach based on Ion Torrent Personal Genome Machine platform. Antibiotics concentrations were at the levels of 1.19-622 ug kg −1 in sediment samples and below the limit of detection to 127 ng L −1 in water samples. Relative abundances (ARGs copies/16S rRNA gene copies) of detected ARGs were at the range of 10 −5 to 10 −2 . The dominant phyla were Proteobacteria, Bacteroidetes, and Verrucomicrobia in sediment samples, and were Proteobacteria, Actinobacteria, and Bacteroidetes in water samples. The results indicated that the river environment was contaminated by antibiotics and may be as a reservoir of ARGs. This study provided quantitative data on antibiotics, ARGs and bacterial community composition in the Liuxi River, a geographical location different from the reported studies.

“…A higher abundance of phylum Chloroflexi was observed in the HWW, compared to the DWW. The phylum Chloroflexi was found in the downstream, receiving the treated penicillin and oxytetracycline production wastewater under long-term antibiotic pressure [31]. The phyla Deinococcus-Thermus and Cyanobacteria were only present in the HWW, indicating that those two phyla were not reported previously in hospital wastewater.…”

“…Interestingly, Cytophagia (14.8%) and Anaerolineae (7.6%) were predominant classes in the HWW, compared to the DWW (1.4% Cytophagia and 1.2% Anaerolineae). Anaerolineae was reported as having high resistance to antibiotics (i.e., tetracycline) [31,36], corresponding to the characteristics of the HWW receiving major antibiotics from hospital chemicals and clinics. In terms of taxonomic classification of class levels, influent characteristics seem to affect microbial richness and diversity, but further investigation is required regarding what types of antibiotics influence microbial communities.…”

Abstract:The community of whole microbes and antibiotic resistance bacteria (ARB) in hospital wastewater treatment plants (WWTP) receiving domestic wastewater (DWW) and hospital wastewater (HWW) was investigated. Samples from an influent of a secondary clarifier, at each treatment train, were characterized for the whole microbial community and ARB on the antibiotic resistance database, based on high-throughput pyrosequencing. The pyrosequencing analysis revealed that the abundance of Bacteroidetes in the DWW sample was higher (~1.6 times) than in the HWW sample, whereas the abundance of Proteobacteria in the HWW sample was greater than in the DWW sample. At the top twenty of the genus level, distinct genera were observed-Saprospiraceae in the DWW and Zoogloea in the HWW. Apart from the top twenty genera, minor genera showed various antibiotic resistance types based on the antibiotic resistance gene database.

“…Epsilonproteobacteria have the ability to oxidize sulfur and sulfide into sulfate, as well as the ability to degrade some toxic substances [64,65]. Additionally, Deltaproteobacteria were shown to be closely related to sulfate reduction in sediment [66].…”

Different characteristics of wastewater have different effects on the diversity and abundance of bacteria and archaea in rivers. There are many creeks around Taihu Lake, and they receive a large volume of industrial wastewater and domestic sewage, which is discharged into these creeks, and finally into Taihu Lake. The present study determined Illumina reads (16S rRNA gene amplicons) to analyze the effects of industrial wastewater and domestic sewage on the bacterial and archaeal communities at the different sampling sites along two creeks. The bacterial and archaeal diversity of the creek receiving sewage was higher than that of the creek receiving industrial waste. Proteobacteria dominated the microbial communities of all samples in both creeks. Betaproteobacteria dominated in the sewage creek, and its abundance declined along the creek. Certain pollutant-resistant classes were more abundant at the site near to the pollution source of the industry creek (e.g., Epsilonproteobacteria and Flavobacteria). Halobacteria belonging to the phylum Euryarchaeota was the dominant archaea at all sites in both creeks, while Methanobacteria was more abundant in the industry creek. The bacterial community was more affected by the distance between the sampling site and the pollutant source than the archaeal community, indicating that bacterial diversity and abundance could be a good index to distinguish domestic and industrial pollution, especially when the main pollution sources are difficult to identify.
