  1. Quantitation of free-living amoebae and bacterial populations in eyewash stations relative to flushing frequency.

    Article - En anglais

    This study investigated the concentration of amoebic and bacterial populations in eyewash station water relative to various flushing regimens.

    Amoebae concentrations averaged approximately 200 amoebae/100 mL in 13 of 15 stations positive for amoebae and consisted of Hartmannella and Acanthamoeba.

    Bacterial concentrations ranged from 10° to more than 105 colony forming units per mL.

    Amoebic concentrations differed notably between stations located in Buildings X and Y (p<0.0001).

    Further study indicated that removal of diffusing screens did not substantially change (p>0.05) the concentration of amoeba.

    Amoebic and bacterial concentrations temporarily decreased with the various flushing regiments tested.

    Lower amoebic concentrations were not sustained by a weekly 3-minute or a monthly 1-minute flushing regimen.

    However, weekly 3-minute flushes appeared to be more effective in maintaining lowered bacterial concentrations (p<0.0001).
