MpsAB is important for Staphylococcus aureus virulence and growth at atmospheric CO2 levels
No full textThe mechanisms behind carbon dioxide (CO2) dependency in non-autotrophic bacterial isolates are unclear. Here we show that the Staphylococcus aureus mpsAB operon, known to play a role in membrane potential generation, is crucial for growth at atmospheric CO2 levels. The genes mpsAB can complement an Escherichia coli carbonic anhydrase (CA) mutant, and CA from E. coli can complement the S. aureus delta-mpsABC mutant. In comparison with the wild type, S. aureus mps mutants produce less hemolytic toxin and are less virulent in animal models of infection. Homologs of mpsA and mpsB are widespread among bacteria and are often found adjacent to each other on the genome. We propose that MpsAB represents a dissolved inorganic carbon transporter, or bicarbonate concentrating system, possibly acting as a sodium bicarbonate cotransporter. © 2019, The Author(s)
Tox-Box: securing drops of life - an enhanced health-related approach for risk assessment of drinking water in Germany Tox-Box: Die Tropfen des Lebens bewahren - Gesundheitsbasierte Risikobewertung für Trinkwasser in Deutschland
No full textThis article introduces ‘Tox-Box’, a joint research project designed to develop a holistic approach towards a
harmonized testing strategy for exposure- and hazard-based risk management of anthropogenic trace substances in
drinking water to secure a long-term drinking water supply. The main task of the Tox-Box consortium is to enhance
the existing health-related indicator value concept (German: GOW-Konzept - Gesundheitlicher Orientierungswert)
through development and prioritization of additional end point-related testing strategies for genotoxicity,
neurotoxicity, germ cell damage, and endocrine effects. In this context, substance-specific modes of action will be
identified and characterized. Toxicological data collected by the 12 Tox-Box subprojects will be evaluated and
weighted to structure a hierarchical testing strategy for an improved risk assessment. A technical guidance
document for exposure and hazard-based risk management of anthropogenic trace substances in drinking water
will eventually be prepared
