... plants. Legionella Water suppliers provide water free of microbiological contamination. Nonetheless, time and again there are reports in the press of legionella being found in large quantities in individual buildings. The new drinking water ordinance prescribes that public buildings, such as schools...

.../MIT biocide versus Legionella bacteria and the protozoa associated with their growth. These studies included a wide range of conditions, including single organisms in cooling water and complex model systems with bacteria, biofilms, and protozoa. Overall, low levels of CMIT/MIT (1-10 ppm active...

... INTRODUCTION ABSTRACT Control of Legionella bacteria came into focus after 1976. Oxidizing and non-oxidizing biocides already approved for use in cooling towers were tested in the laboratory to determine their efficacy against Legionella bacteria. This paper summarizes some...

... ABSTRACT "The Japanese Guideline for Prevention of Legionellosis" will be introduced and the status of Legionella inhibition in cooling water systems in Japan will be discussed. About 9,000 sampling data on Legionella in cooling water systems will be discussed. Seasonal trend was observed...

... ABSTRACT The threat of litigation is present whenever the presence of Legionella bacteria results in illness. Liability may arise against a variety of defendants and under a number of different legal theories. While there is no sure way to protect against liability, an examination...

..., with a MLC of 62,500 ppm. A ciliate and an amoeba species were also exposed to bromochlorodimethylhydantoin. The MLC for the ciliate species was 1 ppm of the biocide product, and the MLC was 30- 40 ppm for the amoeba trophozoites. Since amoebae can expel vesicles containing live Legionella, experiments were...
