“…Thus, it is not surprising that the higher abundance of Arcobacter cryaerophilus in the Pinheiros River may indicate heavy fecal contamination. Nevertheless, our results replicate the findings of the recent metagenomic sequencing studies that revealed a higher prevalence of Arcobacter in sewage ecosystems and wastewater treatment plants [48][49][50] and provides further support to the suggestion that Arcobacter is primarily planktonic 51 . In one study, a metagenomic assembly of the near-complete genome of Arcobacter cryaerophilus from untreated sewage influent samples recovered 25 putative antibiotic resistance genes 52 .…”

“…The sources of Arcobacter in wastewater are not well described, but it is possible that the bacteria grow in biofilms in the sewer systems, as they attach to pipe surfaces (29), or that they grow in the wastewater (30). Some studies suggest that sewers may hold a unique habitat, where Arcobacter thrives, which indicates that sewers potentially hold a large reservoir of pathogens (5,12,25,26).…”

“…Microbial biofilm diversity and community composition have been addressed in several urban drinking and draining water distribution systems, and enrichments of specific communities within biofilms have been reported (Bertelli et al ., ; Bruno et al ., ; Douterelo et al ., ; Douterelo et al ., ; McLellan and Roguet, ). Interestingly, in the street gutter biofilms/mats, we identified 21 OTUs (3 Arcobacter , 12 Acinetobacter , 5 Aeromonas and one Trichococcus ) from genera that were previously shown to be dominant in sewer pipe (McLellan and Roguet, ). Among these OTUs, 5 of them (one Arcobacter , 2 Acinetobacter , one Aeromonas and one Trichococcus ) were among the 50 most abundant OTUs in our dataset.…”

“…This bacterial order that presents interesting metabolic pathways, including carotenoid pigment synthesis (Siddaramappa et al, 2018), was found in various environments from the caves (Marques et al, 2019) to thermal springs (Pedron et al, 2019) and clouds (Amato et al, 2017), and recently, in the drinking water distribution system in Paris (Perrin et al, 2019). Microbial biofilm diversity and community composition have been addressed in several urban drinking and draining water distribution systems, and enrichments of specific communities within biofilms have been reported (Bertelli et al, 2018;Bruno et al, 2018;Douterelo et al, 2018;Douterelo et al, 2019;McLellan and Roguet, 2019). Interestingly, in the street gutter biofilms/ mats, we identified 21 OTUs (3 Arcobacter, 12 Acinetobacter, 5 Aeromonas and one Trichococcus) from genera that were previously shown to be dominant in sewer pipe (McLellan and Roguet, 2019).…”
