Article Synopsis
- - Microbiologically contaminated water poses a risk of infections, especially from Pseudomonas aeruginosa (PSA), which can survive in water and resist disinfectants; this study focuses on how PSA adheres to materials used in mineral water extraction wells.
- - Water samples were collected from three wells in Brazil, and their physicochemical properties, like strontium and iron concentrations, were analyzed, revealing that PSA adhered more to hydrophobic materials like HDPE and PVC.
- - The study found that higher concentrations of certain elements (Sr, Fe, Si, SO, Cl) positively correlated with PSA adhesion on hydrophilic materials, while higher oxidation-reduction potential (ORP) negatively affected PSA attachment to PVC,
Gelatin, a versatile protein derived from collagen, is widely used in the food, pharmaceutical and medical sectors. However, bacterial contamination by spore-forming bacteria during gelatin processing represents a significant concern for product safety and quality. In this study, an investigation was carried out to explore the heat and chemical resistance, as well as the identification and characterization of spore-forming bacteria isolated from gelatin processing.

The resistance to chlorine-based sanitizers, ability to attach to stainless steel surfaces, and antibiogram profile of a large set of S. aureus strains (n = 585) were assessed.

Methods: This is a subanalysis of a previously published study. In anesthetized and mechanically ventilated sheep, we measured the respiratory quotient by indirect calorimetry and its systemic, renal, and intestinal surrogates (the ratios of the venous-arterial carbon dioxide pressure and content difference to the arterial-venous oxygen content difference.
