“…It is also possible that other variables that were not included in our study could be contributed to the bacterial community variability in the Billings reservoir. The observed bacterial richness and diversity indices in this study were comparable to those in other reservoirs (21). Taxonomical composition revealed that the Proteobacteria phyla were most common, followed by Cyanobacteria and Actinobacteria .…”

Here, we describe the microbial diversity and physicochemical properties in freshwater samples from the surface and bottom layer of Billings reservoir in São Paulo state, Brazil. Twenty-two matched samples were characterized using the 16S rRNA gene Illumina MiSeq platform. Taxonomical composition revealed an abundance of Cyanobacteria phyla, followed by Proteobacteria, with 1903 and 2689 known bacterial genera in the surface and deep-water layers, respectively. Shannon diversity index ranging from 2.3 - 5.39 and 4.04 - 6.86 in the surface and bottom layer, respectively. Among the 120 pathogenic genera identified, Flavobacterium was the most predominant genus. Temperature and phosphorus concentration were the most influential factors in shaping the microbial communities of both layers. Predictive functional analysis suggests that the reservoir is enriched in motility genes involved in the flagellar assembly. The overall results present new information on the significantly altered diversity composition of the bacterial community detected in Billings freshwater reservoir.

“…The majority of ARGs reported are those that confer resistance to β-lactam antibiotics, aminoglycosides, fluoroquinolones and macrolides. However, of the studies, 12 (17.6%) did not have precise information on the types of ARGs found, as is the case for the reports made by Port et al [ 27 ], Han et al [ 48 ], Fang et al [ 51 ], Pan et al [ 54 ], Chen et al [ 55 ], Eduardo-Correia et al [ 57 ], Quintela-Baluja [ 42 ], Clarke et al [ 61 ], Fernandes Cardoso de Oliveira et al [ 62 ], Coutinho et al [ 45 ], Miranda et al [ 63 ], Lu et al [ 64 ], Jiang et al [ 65 ], and Qu et al [ 66 ].…”

Aquatic environments have been affected by the increase in bacterial resistant to antibiotics. The aim of this review is to describe the studies carried out in relation to the bacterial population structure and antibiotic resistance genes in natural and artificial water systems. We performed a systematic review based on the PRISMA guideline (preferred reporting items for systematic reviews and meta-analyzes). Articles were collected from scientific databases between January 2010 and December 2020. Sixty-eight papers meeting the inclusion criteria, i.e., “reporting the water bacterial community composition”, “resistance to antibiotics”, and “antibiotic resistance genes (ARG)”, were evaluated according to pre-defined validity criteria. The results indicate that the predominant phyla were Firmicutes and Bacteroidetes in natural and artificial water systems. Gram-negative bacteria of the family Enterobacteraceae with resistance to antibiotics are commonly reported in drinking water and in natural water systems. The ARGs mainly reported were those that confer resistance to β-lactam antibiotics, aminoglycosides, fluoroquinolones, macrolides and tetracycline. The high influence of anthropogenic activity in the environment is evidenced. The antibiotic resistance genes that are mainly reported in the urban areas of the world are those that confer resistance to the antibiotics that are most used in clinical practice, which constitutes a problem for human and animal health.

“…These results are consistent with other Brazilian studies that describe the microbial communities in the Amazon basin [24][25][26] and Tocantins River [27] but somewhat different from those previously described for reservoirs in China. For instance, Qu J et al [23] used the 16S rDNA Illumina approach and showed that Firmicutes, Proteobacteria, Cyanobacteria, and Bacteroidetes were the dominant bacterial phyla in the Miyun Reservoir, which is considered the largest man-made reservoir in North China. These differences of dominant phyla may be due to a variety of environmental factors including air, soil, and water pollution, rainfall-induced nutrient uctuations, and changes in local conditions.…”

Here, we describe the microbial diversity and physicochemical properties in freshwater samples from the surface and bottom layer of Billings reservoir in São Paulo state, Brazil. Twenty-two matched samples were characterized using the 16S rRNA gene Illumina MiSeq platform. Taxonomical composition revealed an abundance of Cyanobacteria phyla, followed by Proteobacteria, with 1903 and 2689 known bacterial genera in the surface and deep-water layers, respectively. Chroobacteria, Actinobacteria, Betaproteobacteria, Alphaproteobacteria, Sphingobacteriia, and Acidimicrobiia were the most dominant classes. Shannon diversity index ranging from 2.3 - 5.39 and 4.04 - 6.86 in the surface and bottom layer, respectively. Among the diverse pathogenic genera identified, Flavobacterium was the most predominant genus.
