An evaluation of sampling and laboratory procedures for determination of heterotrophic plate counts in dental unit waterlines.
BACKGROUND The high numbers of heterotrophic microorganisms that have been cultured from dental unit waterlines (DUWs) have raised concern that this water may exceed suggested limits for heterotrophic plate counts (HPCs). The main purpose of this investigation was to examine HPC variability in DUWs and to examine in detail the effect of laboratory processing of water samples on HPC values. ME...

متن کاملQuantitative analyses of pollution-indicator and pathogenic bacteria in Mumbai waters from ballast water exchange perspective.
As large numbers of ships either take in ballast from or discharge their ballast into the Mumbai Harbor region, it is pertinent to quantify microorganisms of health concerns and suggest on the suitability of water for ballasting purposes. To meet with this main aim, a selected set of general and pathogenic bacterial groups and their seasonal variations were studied from the Mumbai Harbor area. ...
متن کاملEvaluation of Bacterial Contamination in Dental Unit Water Lines in Zahedan in 2016-2017
Background & Aim: Due to a constant contact of dentists and patients with water and aerosols generated from the dental units, the quality of dental unit waters is very important. This study aimed to evaluate bacterial contamination of dental unit water lines in Zahedan in 2016-2017. Methods: In this descriptive analytical study, 2304 water samples from four parts of unit including cup filler, ...
متن کاملMicrobial biofilm formation and contamination of dental-unit water systems in general dental practice.
Dental-unit water systems (DUWS) harbor bacterial biofilms, which may serve as a haven for pathogens. The aim of this study was to investigate the microbial load of water from DUWS in general dental practices and the biofouling of DUWS tubing. Water and tube samples were taken from 55 dental surgeries in southwestern England. Contamination was determined by viable counts on environmentally sele...
