Background: Failures in the processes of cleaning and disinfecting health service surfaces may result in the spread and transfer of pathogens that are often associated with healthcare-related infections and outbreaks.
Aims: To assess the effectiveness of environmental surface cleaning and disinfection in a hospital clinic.
Method: The study was conducted in a nursing ward with 45 beds. A total of 80 samples from five high-touch surfaces were evaluated before and after cleaning and disinfection, using the following methods: visual inspection, adenosine triphosphate bioluminescence assay, aerobic colony count, colony count, and evaluation of resistance to methicillin. The data analysis used nonparametric comparative and correlative tests to observe any differences in the pre- and post- cleaning and disinfection results for the surfaces assessed.
Results: Effective cleaning and disinfection had a significant effect on only two surfaces when measured for the presence of adenosine triphosphate, the inner bathroom door handle (=0.007) and the toilet bowl (=0.01). When evaluated for colony count, the toilet flush handle also demonstrated a significant effect (=0.04).
Conclusion: The effectiveness of cleaning and disinfection of the surfaces tested was not satisfactory. An educational intervention is recommended for the cleaning and disinfection staff and the nursing team at the healthcare facility.
Relevance To Clinical Practice: The data in the study revealed that daily hospital cleaning and disinfection in the sampled sites are not sufficient in medical and surgical wards. Hospital cleanliness must be reevaluated from the point of view of materials, such as an adequate supply of clean cloths, in addition to establishing more precise cleanliness protocols and accurate monitoring systems.

Background: Biosecurity measures are crucial to the introduction and spread of pathogens both within and between farms. External biosecurity focuses on preventing pathogens from entering or leaving the farm, while internal biosecurity aims to limit or stop the spread of pathogens within the farm. Implementing biosecurity measures not only protects animals from disease but also has positive effects on productivity, welfare and farm profitability.

This study evaluated the effectiveness of a biosafety cabinet equipped with an ozone generator, particularly during the transition periods between the production of cell products. As living cell products cannot undergo sterilization, maintaining an aseptic manufacturing environment is paramount. Raw materials, often derived from human tissues, are frequently contaminated with various resident bacteria, necessitating environmental resets after each process.

Introduction: The storage of reusable medical devices (RMDs) is the final reprocessing phase and the step that directly precedes point-of-care delivery. Reusable medical devices, including surgical tools necessitating sterilization and semicritical devices such as endoscopes, undergo high-level disinfection. The rigorous reprocessing protocols and subsequent storage of RMDs are crucial in preserving their sterility and asepsis.

Introduction: In children, polymethylmethacrylate (PMMA) is a commonly used material for fabrication of dental prostheses, such as obturators, removable space maintainers, habit-breaking appliances, removable orthodontic appliances, and removable partial and complete dentures. Regular cleaning of such prostheses is vital for maintaining the health of the oral tissues as well as the longevity of the prosthesis. The chemical method of disinfection, using different chemical cleansers, is commonly used for cleaning a dental prosthesis.
