“…Meanwhile, other contaminants with significant antimicrobial activities could not be ignored in shaping bacterial communities and accordingly selecting antibiotic resistance. Growing evidence has demonstrated the selection of ARB and ARGs by heavy metals (Baker-Austin et al, 2006), as well as by some organic contaminants, e.g., polychlorinated biphenyls (Lo Giudice et al, 2013), pesticides (Anjum and Krakat, 2016), and disinfectants (Karatzas et al, 2007). It is well believed that more organic contaminates will be found to have significant selection for the ARB and ARGs.…”

The prevalence of antibiotic resistance genes (ARGs) in modern environment raises an emerging global health concern. In this study, soil samples were collected from three sites in petrochemical plant that represented different pollution levels of polycyclic aromatic hydrocarbons (PAHs). Metagenomic profiling of these soils demonstrated that ARGs in the PAHs-contaminated soils were approximately 15 times more abundant than those in the less-contaminated ones, with Proteobacterial being the preponderant phylum. Resistance profile of ARGs in the PAHs-polluted soils was characterized by the dominance of efflux pump-encoding ARGs associated with aromatic antibiotics (e.g., fluoroquinolones and acriflavine) that accounted for more than 70% of the total ARGs, which was significantly different from representative sources of ARG pollution due to wide use of antibiotics. Most of ARGs enriched in the PAHs-contaminated soils were not carried by plasmids, indicating the low possibilities of them being transferred between bacteria. Significant correlation was observed between the total abundance of ARGs and that of Proteobacteria in the soils. Proteobacteria selected by PAHs led to simultaneously enriching of ARGs carried by them in the soils. Our results suggested that PAHs could serve as one of selective stresses for greatly enriching of ARGs in the human-impacted environment.

“…The continual use of antibiotics over a long period of time evokes an intense selective pressure on bacteria and triggers antibiotic resistance dissemination among bacteria [2,9,10]. Although most of the bacteria are killed due to the use of antibiotics, sometimes, some bacteria with a vantage are viable as a consequence of conjugative transfer of resistance genes among bacterial communities and high antibiotic resistance competence, respectively [1,10-13,].…”

“…These multi-drug resistance bacteria cause threat to patients in hospitals. Also live stocks have been identified as a serious source for the spread of pathogenic antibiotic resistant bacteria in the environment [3][4][5]10].…”

“…Another important aspect is the co-selection of antibiotic resistances provoked by the presence of heavy metals or xenobiotics, anthropogenically introduced into the environment [10][11][12]18]. This co-resistance could occur due to the fact that the presence of resistance genes of heavy metals, xenobiotics and antibiotics are often located on plasmids which are either transferable or mobilizable.…”

“…This co-resistance could occur due to the fact that the presence of resistance genes of heavy metals, xenobiotics and antibiotics are often located on plasmids which are either transferable or mobilizable. Especially plasmid-mediated horizontal gene transfer (HGT) plays an important role in the emergence of new pathogens [1,9,10,16,19].…”

Antibiotics are used irresponsibly at every opportunity to treat mild or even viral infections. Accordingly antibiotics have been used in massive amounts in agriculture as a preventive provision against bacterial diseases and to promote the growth of animal feedstock such as poultry, beef and pigs, respectively. Consequently many reports of the past decades contained numerous treatises on bacteria's ability to become resistant to antibiotics what in turn is a growing issue in health care. For example a diverse set of clinical pathogens which includes multi-drug-resistant strains of Mycobacterium tuberculosis, Staphylococcus aureus and various Enterococci species are now nearly untreatable with standard antibiotics and pose a growing threat to patients in hospitals and the community at large. Furthermore, antibiotic resistance genes (ARGs) are prevalent in environments resulting in enhanced health hazard risks. Moreover, conjugative transfers of ARGs help to disseminate multiple antibiotic resistant pathogens which pose a serious threat to humans if allowed to enter the food chain. Thus, better knowledge and more information on the fate of antibiotics as well as the development and spread of antibiotic resistance bacteria and genes in the environment are required to understand underlying processes. This review is an effort to emphasize how biotic environments become polluted initiated by several antibiotic applications via human beings.
