Virulent Naegleria fowleri in an indoor swimming pool
Science (New York, N.Y.)
|September 15, 1978
Abstract:
A reservoir of pathogenic Naegleria fowleri has been located in the cracked wall of a swimming pool where repeated outbreaks of primary amoebic meningoencephalitis were observed between 1962 and 1965.
Insights
A pathogenic Naegleria fowleri reservoir was found in a swimming pool wall. This finding is linked to past outbreaks of primary amoebic meningoencephalitis, a serious brain infection.
Area of Science:
- Environmental microbiology
- Infectious disease epidemiology
Background:
- Swimming pools can harbor dangerous pathogens.
- Naegleria fowleri causes primary amoebic meningoencephalitis (PAM).
- Previous PAM outbreaks occurred at this specific swimming pool between 1962 and 1965.
Purpose of the Study:
- To identify the source of Naegleria fowleri in a recreational water setting.
- To investigate the link between environmental reservoirs and disease outbreaks.
Main Methods:
- Environmental sampling of swimming pool structures.
- Microbiological analysis to detect and identify Naegleria fowleri.
Main Results:
- A reservoir of pathogenic Naegleria fowleri was identified within the cracked wall of the swimming pool.
- The location correlates with areas of previous primary amoebic meningoencephalitis outbreaks.
Conclusions:
- Cracked pool walls can serve as a persistent reservoir for Naegleria fowleri.
- Environmental control measures are crucial to prevent future outbreaks of primary amoebic meningoencephalitis.
