An in-vitro study investigating current and novel antimicrobial agents as potential topical treatments for cutaneous infections caused by bacteria, fungi and Leishmania
… assays. Results Polyhexamethylene biguanide (PHMB) is a widely used antiseptic and treatment agent. MIC/MBC and time-kill assays revealed no significant difference in activity between PHMB, polyamidopropyl biguanide (PAPB), and polyhexamethylene guanide (PHMG) (p > 0.05) for both bacterial …

Establishing an ex vivo model of acanthamoeba keratitis and investigating the phenotypic similarities between the protozoan acanthamoeba and human macrophages
… of doxycycline and polyhexamethylene biguanide (PHMB) in stopping the disease progression and the results demonstrated the ability of PHMB to inactivate Acanthamoeba trophozoites with minimal toxicity to the corneal epithelium. Doxycycline was not found to have any major antimicrobial effect on …

Alpha-galactosidase from Lactobacillus salivarius: Isolation, purification, and biochemical characterization
… below pH 4.5. Enzyme activity was inhibited by PHMB, HgCl$\sb2,$ and CuSO$\sb4.$ It appeared that a thiol group is required for catalytic activity. The substrate (pNP-$\alpha$-G) had a protective effect against inhibition by iodoacetamide and NEM. Based on $\rm K\sb{i}$ values against the …

Assimilatory sulfur metabolism in marine microorganisms
… The effect of the suIfhydryl reagent pHMB is similarly much less pronounced than in P. halodurans. These and other differences indicate that the sulfate transport system of A. luteo-violaceus is unique among microorganisms. (2) Growth experiments with P. halodurans and A. …
