Abstract
- An animal laboratory in a teaching hospital is a possible cause of cross infection. We aimed to assess the infection control in our animal laboratory and evaluate the disinfectant effects of a portable pulsed xenon ultraviolet (PX-UV) machine. Samples were taken from the surface of research tables, other high touch places, such as doorknobs, weighing scales, and handles of trolleys, and from air in the barrier system pre- and post-manual cleaning and post-PX-UV disinfection. The bacteria types were identified. We found that routine manual cleaning significantly reduced bacterial colony form unit (CFU)/cm2 (P = .02), and the median of CFU/cm2 reduced from 0.5 pre-cleaning to zero post-cleaning. PX-UV disinfection also significantly reduced residual bacterial counts (P = .002), with the highest counts 10 pre-PX-UV disinfection and 1 afterwards. Without manual cleaning, PX-UV disinfected surfaces significantly (P<br />Highlights • An animal laboratory in a teaching hospital is a possible cause of cross infection. • The disinfectant effect of manual cleaning and portable pulsed xenon ultraviolet (PX-UV) was compared in our laboratory. • Manual cleaning significantly reduced bacterial counts on surfaces and PX-UV significantly reduced residual bacterial counts. • PX-UV, without manual cleaning, significantly reduced bacterial counts on surfaces. • PX-UV significantly reduced bacterial counts in the room air.
