A semi-empirical precision control criterion for duplicate microbial colony counts
Letters in Applied Microbiology, 1996A simple precision criterion (Z) of the logarithmic range (R) of duplicate microbiological determinations was developed. It is based on a freely selected relative technical uncertainty and the observed mean colony count. The model takes into account the different character of the technical and distribution uncertainty.

AbstractIntroductionSome countries have implemented reuse of laparoscopic instruments for cost‐effective purposes. An accurate cleaning as the first step of reprocessing would lead to the effective sterilization. The purpose was to evaluate the effect of cleaning guidelines implementation on microbial load of laparoscopic instruments which were used in

American Journal of Infection Control, 2018
Inadequate environmental disinfection represents a serious risk for health care-associated infections. Technologic advancements in disinfection practices, including no-touch devices, offer significant promise to improve infection control. We evaluated one such device, portable pulsed xenon ultraviolet (PX-UV) units, on microbial burden during an ...

Food Hygiene and Safety Science (Shokuhin Eiseigaku Zasshi)
The upper and lower limits of microbial colony count on agar plate are essential for microbial cell calculation of food samples. In the present study, the limits presented by the three standards of Ministry of Health, Labor, and Welfare of Japan, Food and Drug Administration of US (FDA), and Japanese Industrial Standards (JIS) were studied from the ...

Quaderni Sclavo di diagnostica clinica e di laboratorio, 1986
The quantity of bacteria of 500 urocultures was analyzed in the Laboratory of Clinical Pathology of the "Regina Elena" Institute of Rome (Italy). These evaluations were carried out both by the classic agar colony-count method (CC) and by a new colorimetric system (Dye test, Dt), recently introduced on the market.

[Microbial contamination of water by pipe and hose material. 1. Detection of colony count changes].
Zentralblatt fur Bakteriologie, Mikrobiologie und Hygiene. Serie B, Umwelthygiene, Krankenhaushygiene, Arbeitshygiene, praventive Medizin, 1988Materials may produce a growth of microorganisms by contact with water. Pipes and hoses with a narrow diameter have not yet been tested on their influence on the microbial colonization of the water. A harmful change has been discussed especially in dental treatment units. Pipes and hoses were tested in their influence on the microbial growth for half a
