We investigated the microbial contamination of suction tubes attached to wall-type suction instrument. Microbial contamination of suction tubes used for endoscopy or sputum suction in wards was examined before and after their disinfection. In addition, disinfection and washing methods for suction tubes were evaluated. Suction tubes (N=33) before disinfection were contaminated with 102-108 colon...

This paper examines the microbial quality of treated RBC (Rotating Biological Contactor) and MBR (Membrane Bioreactor) light greywater along a continuous pilot-scale reuse system for toilet flushing, quantifies the efficiency of UV disinfection unit, and evaluates the regrowth potential of selected microorganisms along the system. The UV disinfection unit was found to be very efficient in reduc...

During the COVID-19 pandemic, use of disinfectants, alcohol-based hand sanitizers, and antiseptic wash has surged. As a precaution, many authorities have also increased chlorine dosage in wastewater disinfection to achieve free residual concentration greater than 6.5 mg/liter (1), despite evidence that just above 0.5 can completely inactivate human coronavirus (2). These chemicals reach aquatic...

In infectious diseases we can discern a cause and effect chain, which in particular offers the practicable perspectives of prophylaxis and treatment. However, to date we have not been able to control them. Apart from new epidemics, such as those caused by HIV and SARS, long-forgotten scourges like TB are enjoying a comeback. Furthermore, the advances made in clinical medicine mean that induced ...

Background/Aim. There is no standard protocol for cleaning and desinfection of used endodontic instruments before their sterilization reuse. The aim this study wss to check the efficiency different methods removing biological debris from type hand stainless steel instruments. Methods. A total 120 (forty Kerr-Reamers, Kerr-Files Hedstr?m-Files) (Shenzhen Denco Medical Co., Ltd. Guangdong, China)...
