Biological tests demonstrated that the inactivation of Nosema bombycis (N. bombycis) spores by chlorine dioxide (ClO(2)) occurs very fast and is highly sensitive. The lowest effective inactivation dosage and time was 15mg/mL for 30min. The inactivation of spores was additionally verified by using double color fluorescence stain and spore germination testing. A series of biological changes, including a large number of substrates that were leaked out from the spores included proteins, DNA, polysaccharide, K(+), and Ca(2+), occurred a short time after N. bombycis spores were treated with ClO(2). In addition, the lipid of spores was disrupted and ATPase activity was inhibited, which resulted in the destruction of the inner structure of the spores.

Introduction: Opportunistic infections (IO) are infections of microbiota (fungi, viruses, bacteria, or parasites) that generally do not cause disease but turn into pathogens when the body's defense system is compromised. This can be triggered by various factors, one of which is due to a weakened immune system due to Diabetes Mellitus (DM), which increases the occurrence of opportunistic infections, especially in the oral cavity. Fungal (oral candidiasis) and viral (recurrent intraoral herpes) infections can occur in the oral cavity of DM patients.

Chlorine dioxide (ClO) is a powerful disinfectant widely regarded as a safe and effective hygienic agent in pharmaceutical plants and other manufacturing facilities that require sterility. However, the efficacy of low concentrations of ClO gas on sterilizing spore-forming bacteria remains uncertain. In this study, we investigated the optimal conditions for disinfection of spore-forming bacteria with low concentrations of ClO gas using biological indicators.

Considering the demand for organosulfur materials and the challenges associated with currently used oxidation processes, in this study, we evaluated the counter-cation of sodium chlorite (Na+ClO2-) with tetrabutylammonium chloride (Bu4N+Cl-) to synthesise tetrabutylammonium chlorite (Bu4N+ClO2-). Bu4N+ClO2- exhibited good solubility in organic solvents like chloroform (1.6 g mL-1) and ethyl acetate (0.
