Cr6+ exists in the form of Oxyanions Chromate (CrO42–) and Dichromate (Cr2O72–). Ba, Sb, and B are weapon priming compounds, (Fitchett, 2019) and W is a kinetic bombardment due to its high density (19.3 g/cm3) (Rowlatt, 2014). Lead (Pb) is predominantly released into the environment from human activities such as manufacturing pipes, X-ray shields, lead-acid storage batteries, munitions, and bullets (Abadin et al., 2007; Jaroslawiecka and Piotrowska-Seget, 2014). 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).

Increased resistance appears linked to armed conflicts, notably since widespread media stories amplified clinical reports in the wake of the American invasion of Iraq in 2003. In addition to Apo-PcoA, the periplasmic Cu-chaperone PcoC transports Cu1+ to the periplasm, where CopA from the Cue system and PcoA oxidize Cu1+ to the less toxic form Cu2+. (2002). (2016).

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).

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). Emerg. Amsterdam: Elsevier. Moreover, the DsbA-DsbB (Disulfide Bond) multi-drug efflux system in Burkholderia cepacia induces cross-resistance to β-lactams, kanamycin, erythromycin, novobiocin, ofloxacin, and Zn2+ and Cd2+ metal ions (Hayashi et al., 2000). 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). However, many bacteria developed Cr resistance via 5 reported mechanisms that are mostly plasmid encoded (Camargo et al., 2005; Joutey et al., 2015). This could increase exposure to Cu in wartime and might explain increased observation of A. baumannii in studies conducted in these settings (Davis et al., 2005; Calhoun et al., 2008; Williams et al., 2016).

Folia Microbiol. 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). 79, 129–133. PcoD is an inner membrane Cu transporter that is involved in Cu uptake. This system induces resistance to Zn2+, Cd2+, and Co2+ by activating the expression of czcCBA (Cobalt Zinc Cadmium) efflux pump and to the carbapenem imipenem by suppressing expression of the OprD porin encoding gene (Perron et al., 2004).

FRONTIER - Bite The Bullet. doi: 10.1016/bs.ampbs.2017.02.001, Panda, J., and Sarkar, P. (2012). (2017). Essential heavy metals are required in many biological processes at low concentrations, where they serve as cofactors for metalloenzymes. The Cus system consists of 4 genes forming the cusCFBA operon, which is regulated by a two-component regulatory system (CusS/CusR) (Franke et al., 2003; Silver and Phung le, 2005; Pal et al., 2017). doi: 10.1007/s11356-016-7436-0, Gilmour, M. W., Thomson, N. R., Sanders, M., Parkhill, J., and Taylor, D. E. (2004). The mer operon is present on plasmids and transposons and consists of a cluster of 8 genes merTPCAGBDE regulated by MerR (Silver and Phung le, 2005; Hobman and Crossman, 2014). Cellular targets and mechanisms in the cytotoxic action of non-biodegradable engineered nanoparticles. 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).
