The use of alternative container materials and added oxidants accelerated the inactivation of MS2 coliphage and Escherichia coli and Enterococcus spp. bacteria during solar water disinfection (SODIS) trials. Specifically, bottles made from polypropylene copolymer (PPCO), a partially UVB-transparent plastic, resulted in three-log inactivation of these organisms in approximately half the time required for disinfection in bottles made from PET, polycarbonate, or Tritan(®), which absorb most UVB light. Furthermore, the addition of 125 mg/L sodium percarbonate in combination with either citric acid or copper plus ascorbate tended to accelerate inactivation by factors of 1.4-19. Finally, it was observed that the inactivation of E. coli and enterococci derived from local wastewater was far slower than the inactivation of laboratory-cultured E. coli and Enterococcus spp., while the inactivation of MS2 was slowest of all. These results highlight the importance of UVB in SODIS under certain conditions, and also the greater sunlight resistance of some viruses and of bacteria of fecal origin, as compared to the laboratory-cultured bacteria commonly used to model their inactivation. Furthermore, this study illustrates promising new avenues for accelerating the inactivation of bacteria and viruses by solar disinfection.

Purpose: Urinary tract infections (UTIs) in neonates pose notable challenges in diagnosis and management because of non-specific clinical manifestations and unique physiological characteristics. Understanding the clinical features and pathogen characteristics of UTIs in this population is crucial for tailored diagnostic and therapeutic strategies. This study aimed to investigate varying clinical features and pathogen characteristics of UTIs, thereby offering a holistic perspective on the multifaceted aspects of UTIs in neonates.

Background: Healthcare-associated infections (HAI) caused by multidrug-resistant organisms have emerged as a significant global issue, posing substantial challenges to healthcare systems. Low- and intermediate-level disinfectants are extensively utilized for cleaning and disinfecting surfaces in hospitals to mitigate environmental transmission of HAI. Therefore, the need for more effective and environmentally safe disinfectants is increasing.

Background: Periprosthetic joint infections (PJI) are one of the most devastating complications of total knee arthroplasty (TKA). Patients who have chronic kidney disease (CKD) are more vulnerable to PJI. We aimed to answer the following questions: 1) What are the commonly observed pathogens in PJI after TKA in CKD patients, and do they differ from those in non-CKD patients? and 2) What are the risk factors for PJI after TKA in CKD patients?
Methods: Patients who underwent surgery due to a chronic PJI of the TKA were retrospectively enrolled.
