Influence of chemical speciation and divalent cations on cadmium toxicity during microbial biodegradation of crude oil

Microbial metal toxicity had been attributed to metal concentration and bioavailability, the later factor being dependent on speciation; the distribution of metals into various physicochemical forms. This research was aimed at establishing a correlation between the nature of predominating ligands in natural environments which can associate with metals and influence toxicities to biodegrading microbes. Cadmium, a known...

Effect of amoxycillin/clavulanic acid (Augmentin 625®) on antioxidant indices and markers of renal and hepatic damage in rats

Amoxycillin/clavulanic acid (Augmentin 625®) is an antibiotic which is being advocated by WHO as a drug for treatment of infection. Its efficacy and potential to inhibit microorganisms had led to their increased use. There is the possibility that the drug may have potential toxic effects on humans following consumption. The present investigation was therefore undertaken to study the status of antioxidant defense...
