Studies on the mode of action of the pyrithione biocides
Sodium and zinc pyrithiones (NaPT and ZnPT respectively) are inhibitors of both pathogenic fungi and bacteria and are widely used in the cosmetics industry as preservatives. However, little is known of their mode of action. Growth inhibitory data exhibited NaPT to be a poorer growth inhibitor of …

Studies on the mechanism of zinc pyrithione resistance in Pseudomonas aeruginosa PAO1
… with consecutive passages in sub-MIC of the Pyrithione group of antimicrobial agents and whether or not such passages yielded comparable outer membrane protein shifts.<br/><br/><i>Pseudomonas aeruginosa</i>, an opportunistic Gram-negative bacteria known for its resistance to a wide range of …

Extraction and analysis of pharmaceutical residues in environmental samples using SPE with LC-MS/MS
… the antifouling and anti-dandruff agent zinc pyrithione and a range of illicit drugs and abused pharmaceuticals. As a pre-requisite to all the developed methods, a SPE sample enrichment procedure was also developed focusing upon either off-line formats using modern hydrophilic lipophilic …

Studies on the development of antimicrobial tolerance in monospecies and binary biofilms
… selected antimicrobial agents (including Zinc Pyrithione (ZnPT), Sodium Pyrithione (NaPT), Cetrimide, Benzisothiazolone (BIT) and Thiomersal) and investigating the possibility of cross-resistance between these biocides. This was followed by observation of the action of BIT in binary biofilms …

Copper as an Antibacterial Agent and Disruptor of Protein Stability
… how Cu and a small molecule ionophore called pyrithione (PT) kill bacteria. First, we present antibacterial susceptibility assays that demonstrate PT and a β-lactamase-activated prodrug of PT called PcephPT kill bacteria in a Cu-dependent manner. Cu hyperaccumulated in cells that were …

Acute Toxicity and Sub-Lethal Effects of Non-Point Source Pollutants on Invertebrates
Non-point source pollution is not generated from any single source, rather can arise from a mixture of agricultural, residential, and industrial activities. As a result of these activities millions of tons of chemicals enter into aquatic environments annually with the potential to disrupt the …
