LEGIONELLA, a review

Legionella is the subject of particular interest of scientific community, for two main reasons:

  •   Legionellosis incidence rates in Italy have been increasing steadily since ’97, as well as for greater diagnostic clinical capabilities, but in fact the increase is continuous;
  •  This is a world still to be discovered: beyond the aspects related to the treatment of patients, whose improvements are linked to the greater sensitivity of the experts and clinical equipment, much must still be done in the containment of environmental risk. In fact there is not yet a protocol of prevention and “elected” technical intervention of efficacy which we don’t pretend to define absolute, but at least definitely superior to all the others. The difference also in this case is measurable in the ability of the expert in the matter, to sensitize himself to the specific critical issues of each case to be treated.

In this sense, using a method of intervention rather than another is a choice which depend from a profound analysis of pros and cons in terms of results, collateral damage to things and people, economic feasibility and cost support.

Global Trading have made a choice considering all the aspects known today, nevertheless we keep constantly updated. Today, reading what can be found in the relevant scientific literature, especially in Italy in the field of water treatment, we know that:

  • The treatments which historically have been used, such as hyper-chlorination, can be inexpensive, but also more harmful to systems and users. Another of these historians is the thermal shock, very invasive for systems users health as well as expensive. Finally, the efficacy of both relative to the last defined protocols intervention is lower. On the other hand, the last approvals are not yet the panacea of all ills: see, for example, microfiltration systems that can be installed directly to water taps, which aren’t harmful to users health, but they are very expensive and require maintenance continuously, more than any other kind of treatment.
  • The efficacy of the treatments is determined in how it is possible to attack the biofilm and the sediments naturally formed inside the water ducts. The definitive elimination of the bacterium is extremely improbable: the remediation and disinfection done “today” of a water circuit, can’t prevent the natural rebirth of these sediments “tomorrow”, which is why maintenance and inspection must both be periodic. It is also true that, as studies show, legionella could be dangerous when proliferates and forms ever larger numbers of colonies, finding feed and defense within the biofilm itself. Therefore, eliminating the biofilm and breaking down the number of colonies are the main aims to be achieved in each intervention, ultimately also as form of “preventive treatment” not only in cases of “emergency”.

References about this can be found in field magazines, in Ministry updating notices, but also in academic studies carried out from north to south (University of Naples, Pisa, Modena and Reggio Emilia etc.) especially in recent years, which have proven these data.

We believe in our standards and protocols that we have established working by ten years in this field. Sure that if properly applied to each case, our protocol of intervention guarantees results, low environmental and health impact, and a low costs. It is also sure that there must always be attention and flexibility of which we were discussing above, but which we believe to be one of our particular strengths, combined with the ability to adapt to the customers needs.
