Alshae Logan-Jackson and Joan B. Rose Highlights Pathogenic Legionella species grow optimally inside free-living amoebae to concentrations that increase risks to those who are exposed. The study screened a complete drinking water system and cooling towers for the occurrence of Acanthamoeba and Naegleria fowleriand their cooccurrence with Legionella pneumophila, L. anisa, L. micdadei, L. bozemanii, and L. longbeachae. fowleri was detected more often in… Read more »
By using the readily available system temperature hot water supply (>60C), the patented ILTDU, In-Line Thermal Disinfection Unit, from Horne Engineering facilitates the only effective thermal disinfection of showers, taps, TMVs, their associated pipe-work feeds, ancillary fittings, mixed water deadleg and terminal outlet fitting. In conjunction with high velocity flushing, which shears excess biofilm from internal pipework surfaces (and represents 95% of the water system’s total bio-load) thus improving water quality, regular operation of the ILTDU further aids the risk-management of retrograde pathogens, e.g. opportunistic Pseudomonas Aeruginosa, Non-Tuberculous Mycobacteria and others.
