Comparison of bacterial counts in glove juice of surgeons wearing smooth band rings versus those without rings

Factors interfering with the microflora on hands: a regression analysis of samples from 465 healthcare workers

“…In particular, several studies failed to show differences after surgical hand antisepsis (Jacobson et al. 1985, Waterman et al. 2006, Wongworawat & Jones 2007).…”

Antibacterial Efficacy of Several Surgical Hand Preparation Products Used by Veterinary Students

“…Bacterial colony forming units (CFU)/mL was calculated using direct counting methods with a range from 0 to 300. Plates that yielded growth of >300 colonies were excluded for CFU determination and individual colony isolation . Bacterial colonies on all agar plates were manually counted by the primary investigator with no repetition.…”

“…Plates that yielded growth of >300 colonies were excluded for CFU determination and individual colony isolation. 17,18 Bacterial colonies on all agar plates were manually counted by the primary investigator with no repetition. Bacterial log CFU (logCFU) were determined and reduction in logCFU from the glove juice at each sampling time point (POST and END) were calculated by subtracting the POST or END logCFU from the PRE logCFU.…”

Bacterial and fungal contamination of dental hygienists' hands with and without finger rings

“…However, when washing with soap and rubbing was prolonged up to 25 s, cleaning level around fingers with and without rings was similar 23 . In a sample of twenty veterinary medical students, ten wearing plain rings, ten not wearing rings, no difference in viable flora was detected be tween ring and nonring hands 24 . In a sample of 200 healthcare workers from an intensive care unit, ring wearers showed almost double prevalence of Gram negative bacteria and En terobacteriaceae than nonwearers, but no dif ference with respect of S. aureus 25 .…”
