“…However, other groups that comprise bacteria with recognized ubiquity and genome plasticity, demonstrated by the acquired capacity to degrade xenobiotics or to resist to some antibiotics, such as members of the genera Pseudomonas, Acinetobacter, or family Sphingomonadaceae, are commonly found in tap water (Vaz-Moreira et al 2014). In general, it is difficult to demonstrate the origin of bacteria found in tap water, for in-stance if their occurrence results from the survival to the dis-infection process or if they can enter the system along the distribution network Narciso-da-Rocha et al 2013). Although culture-dependent methods do not suggest that drinking water is an important habitat for bacteria with acquired antibiotic resistance, intrinsic antibiotic resistance is commonly found in tap water in members of groups such as the family Sphingomonadaceae or the genera Pseudomonas or Ralstonia (Vaz-Moreira et al 2014).…”

Over the last decade, numerous evidences have contributed to establish a link between the natural and human-impacted environments and the growing public health threat that is the antimicrobial resistance. In the environment, in particular in areas subjected to strong anthropogenic pressures, water plays a major role on the transformation and transport of contaminants including antibiotic residues, antibiotic-resistant bacteria, and antibiotic resistance genes. Therefore, the urban water cycle, comprising water abstraction, disinfection, and distribution for human consumption, and the collection, treatment, and delivery of wastewater to the environment, is a particularly interesting loop to track the fate of antibiotic resistance in the environment and to assess the risks of its trans-mission back to humans. In this article, the relevance of different transepts of the urban water cycle on the potential enrichment and spread of antibiotic resistance is reviewed. According to this analysis, some gaps of knowledge, research needs, and control measures are suggested. The critical rationale behind the measures suggested and the desirable involvement of some key action players is also discussed.

“…It is worth noting that strain SFA10 was isolated from Songhua River water (China); thus, it may be speculated that this strain represents an Acinetobacter species that is widely distributed in water throughout China. Most of the strains isolated from the middle stream site B were related to A. lwoffii, which has been detected in water treatment plants and in tap water (Narciso-da- Rocha et al, 2013). Most of the strains isolated from the downstream site C were related to A. guillouiae.…”

“…A. johnsonii, A. lwoffii and A. guillouiae represent the most abundant component of Acinetobacter populations of the upstream, middle stream and downstream sites of the river, respectively, based on culture-dependent methods. These members have been detected previously in many aquatic environments (Narciso-da-Rocha et al, 2013;Peleg et al, 2007). However, a greater degree of similar diversity among the three different sites was identified based on culture-independent methods.…”

“…are frequently detected in natural aquatic environments, such as rivers, lakes and tap water. These habitats constitute important sources of bacteria with the potential to infect humans (Narciso-da- Rocha et al, 2013). Therefore, elucidation of the diversity of Acinetobacter populations in aquatic environments is a prerequisite for an improved understanding of the potential health risk or biotechnological applications of Acinetobacter.…”

This study aimed to explore the diversity of river water Acinetobacter populations using culture-dependent and -independent methods. Pyrosequencing indicated that 1.5% of the total sequences from Qiandeng River water were classified as Acinetobacter. Twelve Acinetobacter strains were isolated from three different sampling sites of the Qiandeng River. Based on culture-dependent methods, A. johnsonii, A. lwoffii and A. guillouiae were the most abundantly represented Acinetobacter strains among the upper, middle and downstream populations of the river. Probing of three Acinetobacter-enriched 16S rRNA gene libraries with the Acinetobacter specific probe Act660F revealed 42 unique 16S rRNA gene sequences exhibiting a similarity of 94.9 99.9% with the known Acinetobacter strains. Among the uncultured Acinetobacter sequences, 50%, 58.3% and 68.8% of those obtained from upstream sampling site A, middle stream sampling site B and downstream sampling site C were phylogenetically located within Group I. This Group represented the most abundant strains of Acinetobacter populations in river water based on culture-independent methods. The results indicated that culture-independent methods provide more detailed information on the diversity of Acinetobacter populations than that based on culture-dependent methods. Therefore, the development of new and efficient isolation methods to identify uncultured Acinetobacter species is required.

Abstract. The study presents a review of the occurrence of genetic determinants of antibiotic resistance in tap water. The aim of this study was also to compare the applied methods for antibiotic resistance genes (ARGs) investigations in tap water. As the concentration of ARGs in treated, drinking water is expected to be very low and may cause problems in a standard isolation procedure, the special emphasis is placed on the applied procedures of DNA extraction and their efficiency. The study presents the first attempts to obtain DNA directly from tap water. Further efforts must be put to determine the final amount of obtained DNA and the presence of chosen ARGs among the molecules.
