Furthermore, heavy metals have been used in medical treatments as antimicrobial and anti-parasitic agents to treat skin infections and leishmaniasis respectively; anti-inflammatory compounds to treat itchiness, and in chemotherapy to treat cancer patients (Rizzotto, 2012; Ndagi et al., 2017; Pal et al., 2017).

MDRAb gained media attention after being identified in American soldiers returning from Iraq and treated in US military facilities, where it was termed “Iraqibacter.” However, MDRAb is strongly associated in the literature with war injuries that are heavily contaminated by both environmental debris and shrapnel from weapons. 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).

This resulted in increased bacterial resistance to As via oxidation, reduction, methylation, efflux, and intracellular sequestration on cysteine-rich peptides (Silver and Phung le, 2005; Paez-Espino et al., 2009), and was associated with detrimental health effects ranging from cardiovascular disease, respiratory disorders, gastro-intestinal symptoms, hematological disorders, diabetes, neurological, and developmental anomalies (Chou et al., 2007; Tchounwou et al., 2012). *Correspondence: Antoine G.

When traveling through Arkansas and Oklahoma make sure you … Finally, metallochaperones like Cu chaperones (Cu1+ binding chaperone CusF, Cu1+, and Cu2+ periplasmic chaperones PcoC and PcoE) can bind, trap, and transport metal ions to metalloenzymes and thus, decrease their toxic effects and protect cellular compartments (Yang et al., 2010; Pal et al., 2017).

More importantly, heavy metals can induce selective pressure on microbial populations leading to antimicrobial resistance through a mechanism called “co-selection” which occurs via 3 major ways (Seiler and Berendonk, 2012). This is mediated by a plasmid-borne MT encoding gene, bmtA responsible for Pb sequestration (Naik et al., 2012; Sharma et al., 2017). ATSDR (2011). Rev. Available at: https://www.atsdr.cdc.gov/ (accessed March 22, 2019). (2013). (2005). However, changes in expression, either through mutations in promoter regions or efflux pump regulators, or inactivation of repressors, can lead to the over-expression of an efflux pump or confer resistance (Li et al., 2015; Blanco et al., 2016). Biophys. Available at: https://copperalliance.org.uk/benefits-copper/health/ (accessed March 22, 2019). In humans, Hg has no biological role and at very low concentrations it is fatal, leading to brain, lung, and kidney failure (Risher and Rob, 1999). Multidrug-resistant acinetobacter extremity infections in soldiers. Warfare is associated with significant heavy metal contamination of the environment, due to destruction of built infrastructure and consequent release of HM and direct contamination from exploded ordnance and leakage from unexploded ordnance. This strategy provides a “Pre-defense” strategy as it occurs outside the bacterial cell. Chou, S., Harper, C., ATSDR, Ingerman, L., Llados, F., Colman, J., et al. Microbiol.

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.

For example, Ni can complex with PO3–4, leading to its intracellular precipitation. 65 talking about this. This is achieved via Adenosine triphosphate (ATP) hydrolysis and/or through an electrochemical gradient of protons (Ianeva, 2009). J. Phycol. To actively function, the Pco system requires the action of CopA from the Cue system in addition to PcoA and PcoC. Studies reveal that P. aeruginosa and Alcaligenes eutrophus can extrude Cr6+ by active efflux through ChrA (Chromate) pump (Collard et al., 1994; Alvarez et al., 1999). High concentrations of heavy metal (HM) ions impact agronomic staple crop production in acid soils (pH ≤ 5) due to their cytotoxic, genotoxic, and mutagenic effects. The mer operon consists of a cluster up to 8 genes merTPCAGBDE. Staphylococcus aureus, Providencia spp., Vibrio harveyi, Shewanella spp., and Bacillus spp., can precipitate Pb as phosphate salts (Levinson et al., 1996; Smeaton et al., 2009; Shin et al., 2012). Further research into the role of heavy metals driving antimicrobial resistance, its influence in war zones, and the contribution of A. baumannii as a reservoir, are therefore warranted given the implications for addressing the global AMR crisis. In the periplasm, CueO oxidizes Cu1+ ions to the less toxic form Cu2+. 199–200, 314–320. When CH3-Hg+ enter the cytoplasm via non-specific porin proteins, MerB cleaves the Mercury-Carbon bond and releases Hg2+ in the cytoplasm.
