Environ . Sci . Technol . 40 7440-7444Purpose of the pick upLegionella-like amoebal pathogens (LLAP ) ar known to driving force infections in human beings . Since these organisms argon put up to infect amoebae and these amoebae are found in body of peeing bodies like diversify towers , the authors precious to whether there is any difference in the happening of LLAP infect amoebae between change tower water and water from inseparable sources in presence o f the varied conditions . This is of interest because findings from this study whitethorn show whether cool down towers are reservoirs of this bacteria , and whether these towers located at hospitals , industries , universities and other buildings are potency sources of respiratory infections like pneumonia . If these modify towers are found to harbour these microorganisms , these could be a potency breeding ground for many infections , where the etiology is not confirmedMethods adoptedFor lay outting an answer to their research question , the authors took water samples from cool down towers and ingrained sources , and compared the presence of septic bacteriae . They likewise metrical five environmental parameters ordinary in both these sources , which are associated with the occurrence of bacteria , to verify whether these conditions in cooling towers and inborn water sources could assure the occurrence of infected amoebaeMajor results of this studyThe authors coll ected water samples from cooling towers and ! natural sources in sterile containers . They also thrifty pH , turn organic degree Celsius , temperature at the term of sample array In more than 50 of cooling tower samples (22 fall aside of 40 , infected amoebae were found . In comparison , in only 7 .5 (3 out of 40 ) of natural water samples , infected amoebae were found .

It was also found that as pH and dissolved organic carbon increases , the likelihood of finding infected amoebae increases . The authors concluded that there is 16 times more find to find infected amoebae in cooling towers than in natural sources and these amoebae from cooling tower samples were infected with legionella species bacteriae or other LLAPsOutcomes of the studyThe authors interpret that water from cooling towers frequently contain amoeba associated bacteriae and these bacteriae are found at wide range of environmental conditions in cooling towers . The results typify that cooling towers are sources of infectious pathogens like LLAPs that can make up respiratory infections . This supports the hypothesis that cooling towers are potential cosmos health threats as they pull in the breeding drive for amoeba associated bacteriae . The results imply that we should check for the surmisal that new amoeba associated microorganisms could be developed in cooling towers under the prevailing conditions . The authors conclude by saying that these cooling towers carry the potential to lead to the evolution of new bacterial pathogens...If you want to get a full essay, order it on our website: OrderEssay.net
