  1. Comparison of free-living amoebae in hot water systems of hospitals with isolates from moist sanitary areas by identifying genera and determining temperature tolerance.

    Article - En anglais

    Legionella-contaminated hot water systems and moist sanitary areas in six hospitals were sampled for amoebae by following a standardized collection protocol.

    Genus identifications and temperature tolerance determinations were made.

    Amoebae identified as Hartmannella vermiformis (65%), Echinamoebae spp. (15%), Saccamoebae spp. (12%), and Vahlkampfia spp. (9%) were detected in 29 of 56 (52%) hot water samples.

    Twenty-three of 49 (47%) swabs obtained from moist areas were amoeba positive.

    The following genera were identified :

    • Acanthamoeba (22%),

    • Naegleria (22%),

    • Vahlkampfia (20%),

    • Hartmannella (15%), and Vanella (7%). The temperature tolerance of amoebae from hot water systems was strikingly different from that of amoebae from moist areas.

    At 44°C on agar, 59% of amoebic isolates sampled from hot water systems showed growth.

    The corresponding value for isolates from moist areas was only 17%. Six Acanthamoeba isolates from the moist areas were considered potential pathogens.

    Four Hartmannella and two Saccamoeba isolates from hot water could be cultured at 53°C.
