“…We previously reported that measurement of the adenosine triphosphate (ATP) level was useful as a simple method to evaluate infusion fluid contamination with microorganisms 17 , 37 . Since infusion fluid contamination can be estimated in a few minutes by measuring the ATP level, infusion fluid that is being administered should be checked using a simple detection method with ATP in patients in whom sepsis is suspected based on findings, such as a high procalcitonin level.…”

In Japan, China, and Singapore, several studies have reported increased incidences of peripheral venous catheter-related bloodstream infection by Bacillus cereus during the summer. Therefore, we hypothesized that bed bathing with a B. cereus -contaminated “clean” towels increases B. cereus contact with the catheter and increases the odds of contaminating the peripheral parenteral nutrition (PPN). We found that 1) professionally laundered “clean” towels used in hospitals have B. cereus (3.3×10 4 colony forming units (CFUs) / 25cm 2 ), 2) B. cereus is transferable onto the forearms of volunteers by wiping with the towels (n=9), and 3) B. cereus remain detectable (80∼660 CFUs /50cm 2 ) on the forearms of volunteers even with subsequent efforts of disinfection using alcohol wipes. We further confirmed that B. cereus grow robustly (10 2 CFUs /mL to more than 10 6 CFUs /mL) within 24hours at 30°C in PPN. Altogether we find that bed bathing with a towel contaminated with B. cereus leads to spore attachments to the skin, and that B. cereus can proliferate at an accelerated rate at 30°C compared to 20°C in PPN. We therefore highly recommend ensuring the use of sterile bed bath towels prior to PPN administration with catheter in patients requiring bed bathing.

Rapid adenosine triphosphate (ATP) hygiene monitoring tests have been widely employed in the food industry to ensure that adequate cleanliness is maintained. In this article, the practical applications and limitations of these tests were discussed, while recent technological progress made to facilitate their more accurate control was also outlined. The presence of ATP on a surface indicates improper cleaning and the presence of contaminants, including organic debris and bacteria. In particular, food residues have been recognized as indicators of insufficient cleaning as well as direct hazards that may cause bacterial contamination because they may harbor bacteria, provide sources of nutrients for bacterial growth, interfere with the antimicrobial activity of disinfectants, and support the formation of a biofilm. Moreover, allergenic food residues on a surface may increase the risk of allergen cross-contact. However, it should be noted that ATP tests cannot detect bacteria or allergenic proteins directly. In order to ensure their efficient use, it is necessary to have an in-depth knowledge of their practical applications, methods of setting pass/fail limits, and the differences in the performance of various commercially available ATP tests. Conventional ATP tests, however, have certain limitations as ATP may be hydrolyzed to adenosine diphosphate (ADP) and adenosine monophosphate (AMP), which further hinders the identification of food residues. To overcome this problem, a total adenylate test was developed that could detect ATP+ADP+AMP (A3). The A3 test is suitable for the detection of adenylates from food residues and useful for the verification of hygiene levels. Using the A3 test in conjunction with other test methods, such as microorganism and food allergen tests, may be a useful strategy to diagnose the cause of uncleanliness and facilitate effective hygiene management.
