Environ . Sci . Technol . 40 7440-7444Purpose of the studyLegionella-like amoebal pathogens (LLAP ) argon known to earn infections in human beings . Since these organisms argon found to infect amoebae and these amoebae are found in urine bodies like temperature reduction towers , the authors valued to whether there is any difference in the occurrence of LLAP hold up amoebae between change tower water and water from midland sources in presence of the varied cond itions . 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 alter towers are found to harbour these microorganisms , these could be a probable breeding ground for many infections , where the etiology is not confirmedMethods adoptedFor acquire an answer to their research question , the authors took water samples from cooling towers and internal 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 lifelike water sources could purpose the occurrence of infected amoebaeMajor results of this studyThe authors collected water samples from cooling towers and innate(p) s! ources in sterile check overerers . They also measured pH , gambol organic carbon , temperature at the time of sample gathering In to a greater extent than 50 of cooling tower samples (22 puffiness out of 40 , infected amoebae were found . In equivalence , 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 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 reaching 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 speculation that cooling towers are potential public health threats as they wee the breeding grounds for amoeba associated bacteriae . The results imply that we should check for the mishap that unfermented amoeba associated microorganisms could be developed in cooling towers under the prevailing conditions . The authors conclude by axiom that these cooling towers carry the potential to lead to the evolution of new bacterial pathogens...If you want to get a full essay, instal it on our website: Order CustomPaper.com
