ARB presented diverse resistance to chlorine disinfection during NaClO exposure To observe the dynamics of ARB killing, the inactivation kinetics of four kinds of ARB—E. coli, P. aeruginosa, S. aberdeen and E. faecalis (with RP4)—were investigated during bench-scale inactivation experiments with NaClO, which were carried out in buffered disinfectant demand-free water at pH 7.2 and 20 °C.
Fitted chlorine decay curves and bacterial inactivation kinetics are shown in Supplementary Figs. S1–S3. Chlorine decay constants k′ with different initial NaClO concentrations, and the estimated efficiency factor Hom (EFH) model parameters are summarised in Supplementary Table S4. These data showed that the EFH model was a good fit for the inactivation data of all observed ARB, with R2 above 0.97. The inactivation curves of observed ARB (Fig. 1) were based on the Ct value calculated by fitting the EFH model. Killed ARB after NaClO exposure can donate transferable plasmids to surroundings.

FRONT. MICROBIOL 06/09/18 The Changing Face of Water: A Dynamic Reflection of Antibiotic Resistance Across Landscapes. Introduction Antibiotic resistance (AR) is recognized as a critical global health emergency, with expected increases in deaths worldwide from diseases that were once treatable (World Health Organization, 2014).
Antibiotics are routinely used in human and veterinary medicine to treat or prevent infectious disease. They are also often used in agricultural production systems where they can suppress bacterial diseases as well as promote the growth of livestock and crops. However, decades of misuse and over-consumption of antibiotics have exerted enormous selective pressures on bacterial communities, driving the evolution of resistance (Davies, 2007; Zhang et al., 2009). The wide range of antibiotics and the facility with which bacteria evolve and acquire resistance genes results in AR profiles that can range from resistance to a single antibiotic to multidrug resistance. Across environments, surface water remains a critical connecting resource. Methods Study Site. SCIENCE DAILY 10/10/18 Understanding water's role in antibiotic resistance emergence and dissemination in Africa. Greater access to antibiotic drugs, together with their misuse and overuse, has accelerated the emergence of antibiotic resistant bacteria worldwide.
A new study now suggests that surface water dynamics are a crucial contributor to this growing global health concern. Funded by the National Science Foundation, Kathleen Alexander and Claire Sanderson of Virginia Tech's College of Natural Resources and Environment, together with researchers from two other universities, have used the Chobe River, the only permanent surface water resource in northern Botswana, to explore antibiotic resistance emergence and dissemination. Alexander's unique field site in Botswana encompasses Chobe National Park, home to the largest population of African elephants in the world, as well as two townships.
More importantly, the site lacks commercial agriculture or large-scale medical facilities, both believed to be main contributors to antibiotic resistance. PEERJ 12/10/18 Agrichemicals and antibiotics in combination increase antibiotic resistance evolution. Significance Neither reducing the use of antibiotics nor discovery of new ones may be sufficient strategies to avoid the post-antibiotic era.
This is because bacteria may be exposed to other non-antibiotic chemicals that predispose them to evolve resistance to antibiotics more quickly. Herbicides are examples of some of the most common non-antibiotic chemicals in frequent global use. We previously showed that in some combinations the herbicides we tested made bacteria phenotypically resistant to higher concentrations of antibiotics, while in other combinations bacteria became susceptible at lower antibiotic concentrations. Here we demonstrate that in both cases the herbicides worked with antibiotics to accelerate genotypic resistance evolution.

Front Med (Lausanne). 2017 Oct 30;4:183. Infections Caused by Antimicrobial Drug-Resistant Saprophytic Gram-Negative Bacteria in the Environment. Introduction In 2013, the Centers for Disease Control and Prevention released a report “Antibiotic Resistance in the United States, 2013” that classified groups of drug-resistant microorganisms into “urgent threat,” “serious threat,” and “concerning threat” pathogens (1).
Drug-resistant Gram-negative bacterial (GNB) pathogens comprised 2 of the 3 “urgent threat” pathogens and 7 of 12 “serious threat” pathogens (1). GNBs cause about one-third of healthcare-associated (HCA) infections in the United States, and the proportion of multidrug-resistant and non-fermentative organisms (Pseudomonas aeruginosa, Acinetobacter baumannii) causing these infections has increased dramatically in the last 20 years, according to the National Healthcare Safety Network (NHSN) surveys (2). Most of the new antimicrobial drug-resistance mechanisms discovered during the last 20 years have been those found in GNBs (4–11). Saprophytes are environmental microorganisms that survive on dead organic matter. Methods.

Le fumier, un nouveau rôle dans l'antibiorésistanceDR L’épandage de fumier favorise l’émergence dans le sol de bactéries résistantes aux antibiotiques, qui contaminent les cultures.
Or ce phénomène se produit même lorsque les animaux n’ont pas été traités aux antibiotiques, révèle une étude publiée dans les Proceedings of the National Academy of Sciences (Pnas). Le fumier constitue une importante source d’antibiorésistance, rien de neuf là-dedans. Or on pensait qu’elle ne survenait qu’avec du fumier provenant d’animaux ayant reçu des antibiotiques, dont les excréments recèlent des germes rendus résistants. Mais ce n’est pas toujours le cas, comme le montrent Nikolina Udikovic-Kolic, biologiste à l’université Yale à New Haven (Connecticut), et ses collègues. Dans leur étude, les chercheurs montrent que même le fumier provenant d’animaux non traités favorise la prolifération dans le sol de bactéries résistantes qui s’y trouvaient déjà.
