Vorkommen von Legionellen in Warmwassersystemen in Sachsen-Anhalt.
Traduction en anglais : Incidence of Legionella in warm water systems in Sachsen- (Saxony-) Anhalt, Germany.
The incidence of Legionella in warm water systems of Sachsen- (Saxony-) Anhalt was investigated.
The Legionella were isolated from water samples using plate cultures followed by serotyping methods.
In high-risk areas of Legionella infections such as hospitals and homes for the aged, 48% respectively 43% of the samples were positive.
Warm water systems of 61% of the hospitals and 43% of homes for aged people were found to be contaminated with Legionella.
The number of Legionella were most frequently (50.7%) between 10 and 100 colony-forming units/ml (cfu/ml).
High-level Legionella contamination (>1000 cfu/ml) were detected only in 0.6% of the samples.
Legionella pneumophila serogroup 1 (L. p. SG 1) was identified rarely.
The reasons for positive Legionella findings are old drinking water heating systems and conduits.
To decrease Legionella growth, reconstruction of the old systems according to the recommendations [1,2] is imperative.
