Abstract

Bacterial surface contamination is an important reservoir for micro-organisms and a potential route for transmission. ATP bioluminescence is a relatively new method to assess environmental contamination, and gives direct results.

Highlights

  • Bacterial surface contamination is an important reservoir for micro-organisms and a potential route for transmission

  • ATP bioluminescence was expressed in relative light units (RLU), AAC was expressed in cfu/cm2; for the analysis a Natural Logarithmic transformation was performed to obtain an normal distribution of the values (LnRLU and LnCFU)

  • Toilet seats were significantly associated with higher RLU (P

Summary

Introduction

Bacterial surface contamination is an important reservoir for micro-organisms and a potential route for transmission. ATP bioluminescence is a relatively new method to assess environmental contamination, and gives direct results. The ATP and ACC results of the 98 paired samples showed a good correlation between LnRLU and LnCFU (R2=0.277; P
