Photocatalysis Inhibits the Emergence of Multidrug-Resistant Bacteria in an Antibiotic-Resistant Bacterial Community in Aquatic Environments

Bacterial antibiotic resistance has recently attracted increasing amounts of attention. Here, an artificially antibiotic-resistant bacterial community (ARBC) combined with five different constructed bacteria (ARB) single resistance, namely, kanamycin (KAN), tetracycline (TET), cefotaxime (CTX), polymyxin B (PB), or gentamicin (GEM), was studied for the stress response to photocatalysis. With photocatalytic inactivation, transfer and diffusion genes (ARGs) in ARBC decreased, fewer multidrug-resistant (MDRB) emerged aquatic environments. After several days inactivation Luria broth cultivation, >90% ARB were transformed antibiotic-susceptible by discarding ARGs. Bacteria double dominant species (99%) residual ARB. The changes ARG abundance varied, decreasing GEM TET KAN genes. change level consistent abundance. Correspondingly, point mutations occurred KAN, CTX PB after which might be reason why these persisted longer ARBC. In summary, could reduce some ARGs inhibit emergence MDRB as well block This work highlights advantages long-term controlling facilitates a better understanding communities real

Researchers have extensively studied the effect of oxygen on growth and survival bacteria. However, impact bacterial community structure, particularly its ability to select for taxa within context a complex microbial community, is still unclear. In 21-day microcosm experiment, we investigated aerobic exposure fecal structure succession pattern in broiler, calf, piglet feces (

Abstract Background Aquaculture is an important food source worldwide. The extensive use of antibiotics in intensive large-scale farms has resulted resistance development. Non-intensive aquaculture another aquatic feeding model that conducive to ecological protection and closely related the natural environment. However, transmission resistomes non-intensive not been well characterized. Moreover, influence on human health needs be further understood. Here, metagenomic approach was employed identify mobility estimate potential risks health. Results results demonstrated antibiotic genes (ARGs) were widely present systems multidrug type most abundant accounting for 34%. ARGs environments mainly shaped by microbial communities 51%. Seventy-seven genera 36 mobile genetic elements (MGEs) significantly associated with 23 ARG types ( p < 0.05) according network analysis. Six defined as core (top 3% occurrence frequency > 80%) which occupied 40% abundance fish gut samples. Seventy-one ARG-carrying contigs identified 75% them carried MGEs simultaneously. qacEdelta 1 sul formed a stable combination detected simultaneously humans. Additionally, 475 high-quality metagenomic-assembled genomes (MAGs) recovered 81 MAGs ARGs. bacitracin MAGs. Strikingly, Fusobacterium _A (opportunistic pathogen) carrying both system guts, indicated transfer. Conclusions pathogenicity explored approach. Given observed co-occurrence between environment human, more stringent regulation may required.
