(2) Reducing Pb accumulation via intracellular and extracellular precipitation. Inorganic As occurs as pentavalent Arsenate (As5+), trivalent Arsenite (As3+), elemental Arsenic (As0), and Arsenide (As3–) with As3+ and As5+ being the most toxic inorganic forms and most prevalent in nature (Nies, 1999; Paez-Espino et al., 2009; Tchounwou et al., 2012). Risher, J., and Rob, D. (1999). The role of this pathway in A. baumannii is poorly understood. In Gram-negative bacteria, the mer operon is regulated by MerR, which is in turn activated by increased Hg2+ levels in the cytoplasm. “I am awakened,” says James Durbin. Rep. 53, 1063–1066. Resistance to Copper via the Cue and Cus systems.

Because of this critical development associated with the loss of the therapeutic potential of antibiotics, some reports are already describing the start of the post-antibiotic era with the consequence of rising difficulties in the treatment of infectious diseases (Alanis, 2005). Bacterial antimicrobial metal ion resistance. Heavy metals are a group of non-biodegradable metals and semi-metals (Metalloids) with high atomic weight and a density greater than 5 g/cm3. Dunham, W. (2019). The former encodes an intracellular ATPase which binds ArsB to form an ArsA-ArsB ATPase Efflux Pump, while the latter is a metallochaperone that binds and delivers As3+ and Sb3+ to ArsA-ArsB complex for efflux, in addition to its role as a trans-activating co-repressor of the ars operon along with ArsR (Silver and Phung le, 2005; Paez-Espino et al., 2009; Hobman and Crossman, 2014). doi: 10.1007/s11738-009-0455-4.

In fact, on the finale, he appeared with undisputed metal gods Judas Priest for rousing renditions of “Livin’ After Midnight” and “Breaking The Law”. Besides As toxicity, bacteria belonging to the Shewanella spp., Sulfurospirillum spp., Clostridium spp., and Bacillus spp., use As5+ as a final electron acceptor during anaerobic respiration by reducing it to As3+, while other bacteria use As3+ as an electron donor and oxidize it to As5+ during aerobic oxidation (Paez-Espino et al., 2009). Many reports highlighted the importance of WGS as an effective tool to detect genome-wide modifications and the emergence of heavy metal resistance genes.

Molecular analysis of the copper-transporting efflux system CusCFBA of Escherichia coli. copA and cueO are activated by a cytoplasmic transcriptional Cu-responsive Regulon (CueR) upon sensing increased Cu concentrations (Hobman and Crossman, 2014; Delmar et al., 2015; Pal et al., 2017; Figure 1). The use of next generation sequencing for improving food safety: translation into practice. Co-resistance occurs when genes encoding resistance to heavy metals and antimicrobial agents are physically linked/located in close proximity to each other on mobile genetic elements such as plasmids, genomic islands (GIs), transposons, or integrons (Trevors and Oddie, 1986; Seiler and Berendonk, 2012; Yu et al., 2017). PENDER, Nebraska 68047 . Pb binding-MTs were reported in Pb resistant P. aeruginosa strain WI-1 and Providencia vermicola strain SJ2A. The mechanisms described above, whereby heavy metals may produce antimicrobial resistance in their absence, identifies a potential pathway driving global antimicrobial resistance that would not be addressed through improved antimicrobial stewardship.

Bacterial resistance to As is mainly encoded by efflux via the ars operon, which can be plasmid or chromosomally driven, even though it can also be encoded by other genetic determinants such as arr genes and aox genes (Figure 4; Silver and Phung le, 2005; Paez-Espino et al., 2009). 199–200, 314–320. 578, 202–209. 8, 9–14.

Furthermore, heavy metals can act as competitive inhibitors leading to the displacement of essential ions from their target sites (Ianeva, 2009; Jan et al., 2015). Arsenic (As) is released into the environment from soil and rock erosion, volcanic eruptions, mining, and crops treated with pesticides and herbicides (Paez-Espino et al., 2009; Tchounwou et al., 2012).

When in excess, Pb, Cd, Cu, As, Ag, and Zn can induce oxidative damage in bacterial cells which leads to the production of free radicals that cause DNA damage and destabilize membranous integrity through lipid peroxidation (Szivák et al., 2009; Jaroslawiecka and Piotrowska-Seget, 2014; Williams et al., 2016).

For example, ATP Binding Cassettes (ABC) play a role in the efflux of metal ions and antimicrobial agents driven by ATP hydrolysis, while RNDs and SMRs pump out metal cations and antimicrobial agents via Chemiosmosis/Proton motive force (Silver and Phung le, 2005; Kourtesi et al., 2013; Abbas et al., 2017). For example, the arsenic resistance cassette, arsRCDAB, present on a class 1 integron and mobilized on a conjugative plasmid was detected in two Salmonella enterica isolates from Singapore with high tolerance to arsenate (Wilson et al., 2019). The epidemiology and control of Acinetobacter baumannii in health care facilities. The solubility and oxidizing potential of Cr6+ makes it 1000× more toxic to humans as compared to Cr3+, and this makes it a strong factor associated with nasal and bronchogenic carcinomas (International Agency for Research on Cancer [IARC], 1990; Ahemad, 2014). doi: 10.1128/jb.181.23.7398-7400.1999, Appenroth, K.-J.

Essential and non-essential heavy metals become toxic when exceeding specific concentrations that vary between different metals (Appenroth, 2010). Microbiology 160(Pt 1), 12–25. At this point, Hg2+ is reduced to Hg0 that diffuse outside the bacterial cell (Nies, 1999; Boyd and Barkay, 2012; Hobman and Crossman, 2014; Pal et al., 2017). Genomic Sci.

S. aureus, Providencia spp., and Pseudomonas spp., can precipitate Pb intracellularly in the form of Lead(II) phosphate [Pb3(PO4)2], while in Citrobacter freundii, extracellular Pb precipitation is mediated by phosphatase. No use, distribution or reproduction is permitted which does not comply with these terms. (2014). Due to the widespread Pb contamination, bacteria have developed Pb resistance mechanisms (Levinson et al., 1996; Jaroslawiecka and Piotrowska-Seget, 2014). Explosives harbor huge amounts of Pb and Hg [Mercury(II) fulminate] (Navy U. S., 2008; Gebka et al., 2016). A., de Carvalho, M. A., de Souza, S. A., Dias, P. M., da Silva Filho, R. G., de Meirelles Saramago, C. S., et al. US Military Targets Toxic Enemy #1: Hexavalent Chromium. Lead resistance and sensitivity in Staphylococcus aureus. Copper and zinc, biological role and significance of copper/zinc imbalance. In addition, resistance to antimicrobial agents, Co, and Cu is mediated via the CmeABC multi-drug efflux pump in Campylobacter jejuni (Lin et al., 2002). Lead resistance in micro-organisms.
