“…The antibiotic resistance of coliform bacteria to sulfamethoxazole and trimethoprim in the Yitong River was approximately 9-40%, which was similar to the resistance of E. coli isolates to sulfonamides found in our study [33]. Various studies indicate that solar radiation can inhibit some antibiotic-resistant E. coli, and therefore affect their dispersion [34,35]. The risk of the development of resistance to sulfamethoxazole in surface water was found to be higher compared to ciprofloxacin, which may explain the high prevalence of SXT-resistant E. coli found in our study [35].…”

The risk of the development of resistance to sulfamethoxazole in surface water was found to be higher compared to ciprofloxacin, which may explain the high prevalence of SXT-resistant E. coli found in our study [35]. Overall, the high prevalence of resistance to tetracyclines and sulfonamides found in site 1 indicates that outlets may serve as large reservoirs of antibiotic-resistant bacteria, and they may play an important role in transferring antibiotic resistance.…”

To determine the potential of the recreational marine environment as a dissemination vector of antibiotic-resistant microorganisms, the dissemination of antibiotic-resistant E. coli strains isolated from an urban coastal beach was studied. Sixty-nine and thirteen E. coli strains were isolated from the seawater and sand, respectively, in Fujiazhuang bathing beach, China. The average Antibacterial Resistance Index (ARI) value detected in the seawater is approximately three times that in beach sand. All the isolates from the sand were grouped into one cluster and only the isolates from the municipal sewage outlet were classified into three antibiogram clusters that were observed in the hetero-sites of the E. coli isolates. The E. coli strains with multiple antibiotic resistance (58% of total) were prevalent in the seawater, whereas the isolates from the sand were not detected with multiple antibiotic resistance. A significant association (p < 0.05) between all phenotypic and relative genotypic resistance profiles was observed in the isolates, except in the quinolones resistance genotype. The presence of a class 1 integron was significantly correlated with the resistance of E. coli to sulfonamides, streptomycin, and levofloxacin (p < 0.01). This study revealed that the municipal sewage discharge may impact the dissemination of antibiotic-resistant strains in the urban coastal beach, and that the class 1 integrons play an important role in mediating the resistance of E. coli to sulfonamide antibiotics.

“…As características biológicas do esgoto sanitário são determinadas por uma complexa variedade de patógenos que é excretada por humanos nas fezes, urina e descamação da pele (MARTÍNEZ-PUCHOL et al, 2020). A contaminação ocasionada por esses patógenos provenientes do esgoto contribui para a perda da qualidade da água (BETANCOURT et al, 2014;GARCÍA-ALJARO et al, 2018) e pode causar prejuízos à saúde pública, visto que os corpos hídricos receptores tornam-se reservatórios de microrganismos patogênicos resistentes à antibióticos (AMÉRICO-PINHEIRO et al, 2021;STORTO et al, 2021).…”

The treatment and disposal of domestic sewage is one of Brazil's main challenges. Sewage composition varies with the habits of the population and the frequency with which new contaminants are released into the environment. This study is a bibliographical review of the main aspects related to the characterization and composition of sanitary sewage, types of sewage treatment systems and pertinent legislation; and toxicity of domestic effluents. The review was based on publications available on Science Direct, Google Scholar and Scielo, as well as on printed publications, relevant legislation, and normative instructions. The research period adopted for the selection of publications was from 2005 to 2021. We found out that, in addition to the levels of organic matter from domestic sewage, residues from products used in daily life, such as pharmaceuticals and cleaning products, can be found in effluents in concentrations harmful to the environment. Often, the types of treatment used in municipal sewage treatment plants do not efficiently remove these contaminants. Thus, even if sewage is treated to meet the limits required for the physical-chemical and biological parameters established by law, domestic effluent can present a high potential for toxicity to various aquatic species such as microcrustaceans, mollusks and fish. Thus, ecotoxicological analyses represent a remarkable mechanism for indicating the efficiency of removal of emerging contaminants present in treated sanitary effluent, in addition to indicating the deleterious effects caused by these residues to the environment and ecosystems associated with the receiving water body.

“…These changes are well regulated and can be passed on to the next generations as well. The emergence of resistance against several anti-microbial drugs in numerous microorganisms is a good example of microbial adaptation (Américo-Pinheiro et al 2021;Storto et al 2021). The resistance to penicillin by Staphylococcus aureus was reported soon after its introduction and by 1990, 80% of S. aureus were reported as resistant to this drug (Lowy 2003).…”

Microorganisms are ubiquitous on Earth and can inhabit almost every environment. In a complex heterogeneous environment or in face of ecological disturbance, the microbes adjust to fluctuating environmental conditions through a cascade of cellular and molecular systems. Their habitats differ from cold microcosms of Antarctica to the geothermal volcanic areas, terrestrial to marine, highly alkaline zones to the extremely acidic areas, and freshwater to brackish water sources. The diverse ecological microbial niches are attributed to the versatile, adaptable nature under fluctuating temperature, nutrient availability, and pH of the microorganisms. These organisms have developed a series of mechanisms to face the environmental changes and thereby keep their role in mediate important ecosystem functions. The underlying mechanisms of adaptable microbial nature are thoroughly investigated at the cellular, genetic and molecular levels. The adaptation is mediated by a spectrum of processes like natural selection, genetic recombination, horizontal gene transfer, DNA damage repair, and pleiotropy-like events. This review paper provides the fundamentals insight about the microbial adaptability besides highlighting the molecular network of microbial adaptation under different environmental conditions.
