“…Also, in both phases, the abundance of bacteria was higher in H1 than in H2. Our results are also in line with previous reports that have shown a higher bacterial richness in sediments than in the water column of several environments (Ye et al, 2009;Dai et al, 2016;Narciso-da-Rocha and Manaia, 2016). The lower abundances found in the H2 samples on both media might be due to the possible presence of toxic pollutants emitted by nearby industries.…”

“…The most frequent profiles included resistance to eight antibiotics (128 isolates and 22 profiles), while the most diverse included resistance to 6 or 7 antibiotics (26 profiles each). 92.7% of the isolates were MRB [resistance to 4 or more antibiotic classes (Narciso-da-Rocha and Manaia, 2016)]. Table 1 summarizes the profiles/isolates ratios in each group.…”

“…Eleven antibiotics representatives of different mechanisms of action were chosen. The antibiotic concentrations to use for susceptibility testing of environmental bacteria have not been standardized; and the reported studies used different concentrations (D'Costa et al, 2006;Bhullar et al, 2012;Voolaid et al, 2012;Narciso-da-Rocha and Manaia, 2016;Jardine et al, 2017). In this study, we wanted to focus on the ARs that might be relevant for the ecosystem and for clinical microbiology.…”

Bacterial resistance to antibiotics is an ever-increasing phenomenon that, besides clinical settings, is generally assumed to be prevalent in environmental soils and waters. The analysis of bacteria resistant to each one of 11 antibiotics in waters and sediments of the Huelva's estuary, a multi-contaminated environment, showed high levels of bacteria resistant mainly to Tm, among others. To further gain knowledge on the fate of multi-drug resistance (MDR) in environmental bacteria, 579 ampicillinresistant bacteria were isolated tested for resistance to 10 antibiotics. 92.7% of the isolates were resistant to four or more antibiotic classes, indicating a high level of multi-resistance. 143 resistance profiles were found. The isolates with different MDR profiles and/or colony morphologies were phylogenetically ascribed based on 16S rDNA to phyla Proteobacteria, Firmicutes, Actinobacteria, and Bacteroidetes, including 48 genera. Putative intrinsic resistance was detected in different phylogenetic groups including genera Altererythrobacter, Bacillus, Brevundimonas, Erythrobacter, Mesonia, Ochrobactrum, and Ponticaulis. Correlation of the presence of pairs of the non-intrinsicresistances in phylogenetic groups based on the kappa index (κ) highlighted the co-habitation of some of the tested pairs at different phylogenetic levels. Maximum correlation (κ = 1.

“…Rivers are thus often contaminated with antibiotic-resistant bacteria. A wide range of the bacterial diversity including antibiotic-resistant bacteria and genes in urban rivers has been investigated Narcisoda- Rocha and Manaia, 2016;Proia et al, 2018 . It was suggested that bacterial communities shift due to changes in water quality, affecting the abundance and diversity of antibiotic-resistant genes Zhou et al, 2017 . Fecal coliforms are generally used as an indicator of bacteriological water quality for drinking.…”

Antibiotic-resistance of Fecal Coliforms at the Bottom of the Tama River, Tokyo

We investigated the midstream bottom of the Tama River, which flows through Tokyo, to evaluate the occurrence and degree of antibiotic-resistant fecal coliforms including multidrug-resistant fecal coliforms. The genera Klebsiella and Escherichia were the major isolates among the fecal coliforms. For the genus Klebsiella, the highest antibiotic resistance was observed for ampicillin 100% , followed by kanamycin, tetracycline, cefotaxime, and cefoxitin. The highest resistance to E. coli was found for kanamycin 44.4% , followed by ampicillin, tetracycline, chloramphenicol, amoxicillin-clavulanate, cefotaxime, ceftazidime, and aztreonam. Multidrug resistance MDR was observed in three E. coli isolates. A double disc synergy test confirmed the production of extended-spectrum-lactamases by the six-antibiotic-resistant isolate E. coli hfa7, and the strain had CTX-M-1 group gene. Assessments of antibiotic-resistant fecal coliforms at the bottom of the Tama River are important toward the goals of preventing the spread of antibioticresistant fecal coliforms in humans, animals, and the environment.

“…It has been documented that water is one of the most important habitats on Earth and serves as a significant reservoir of antibiotic resistance [35,36]. It has also been reported that water is the primary receptor and serves as a path to disseminate bacteria from human and animal origin [37]. An impressive number of studies have demonstrated that treated and untreated urban, and hospital effluents, wastewater treatment plants (WWTP), and rainfall play an essential role in the spread of antibiotic resistance in the aquatic environment [38][39][40][41][42][43].…”

In the past few decades, infectious diseases have become increasingly challenging to treat, which is explained by the growing number of antibiotic-resistant bacteria. Notably, carbapenem-resistant Enterobacteriaceae (CRE) infections at global level attribute a vast, dangerous clinical threat. In most cases, there are enormous difficulties for CRE infection except a few last resort toxic drugs such as tigecycline and colistin (polymyxin E). Due to this, CRE has now been categorized as one among the three most dangerous multidrug resistance (MDR) pathogens by the US Centres for Disease Control and Prevention (CDC). Considering this, the study of the frequency of CRE infections and the characterization of CRE is an important area of research in clinical settings. However, MDR bacteria are not only present in hospitals but are spreading more and more into the environment, thereby increasing the risk of infection with resistant bacteria outside the hospital. In this context, developing countries are a global concern where environmental regulations are often insufficient. It seems likely that overcrowding, poor sanitation, socioeconomic status, and limited infrastructures contribute to the rapid spread of MDR bacteria, becoming their reservoirs in the environment. Thus, in this review, we present the occurrence of CRE and their resistance determinants in different environmental compartments in India.
