Environ . Sci . Technol . 40 7440-7444Purpose of the studyLegionella-like amoebal pathogens (LLAP ) ar known to gain infections in human beings . Since these organisms ar found to infect amoebae and these amoebae are found in urine bodies like temperature reduction towers , the authors dodgy to whether there is any difference in the occurrence of LLAP afford amoebae between change tower water and water from infixed sources in presence of the varied conditions . This is of interest because determinations from this study whitethorn show whether alter towers are reservoirs of this bacterium , and whether these towers located at hospitals , industries , universities and different buildings are capableness sources of respiratory infections like pneumonia . If these modify towers are found to harbour these microorganisms , these could be a probable breeding ground for many infections , where the etiology is not confirmedMethods adoptedFor acquiring an answer to their research question , the authors took water samples from cooling towers and inseparable sources , and compared the presence of infected bacteriae . They also measured five environmental parameters prevailing in both these sources , which are associated with the occurrence of bacteria , to verify whether these conditions in cooling towers and immanent water sources could organise the occurrence of infected amoebaeMajor results of this studyThe authors collected water samples from cooling towers and infixed sou! rces in sterile withstanders . They also measured pH , warp organic carbon , temperature at the time of sample accumulation In to a greater extent than 50 of cooling tower samples (22 protrude out of 40 , infected amoebae were found . In simile , 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 venture to find infected amoebae in cooling towers than in natural sources and these amoebae from cooling to wer 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 say of environmental conditions in cooling towers . The results mean that cooling towers are sources of unhealthful pathogens like LLAPs that can produce respiratory infections . This supports the supposal that cooling towers are potential public health threats as they wee the breeding grounds for amoeba associated bacteriae . The results imply that we should consort for the mishap that novel amoeba associated microorganisms could be developed in cooling towers under the prevailing conditions . The authors conclude by say that these cooling towers carry the potential to lead to the evolution of new bacterial pathogens...If you want to get a full essay, coordinate it on our website: OrderCustomPaper.com< br/>
