The Effect of Some Physical and Chemical Inhibitors on Growth of Legionella pneumophila

This study involved the effect of some physical inhibitors such as heat, ultraviolet light and microwave radiation as well as some chemical inhibitors such as ethyl alcohol, propanol alcohol, gluteraldehyde and formalin at different concentrations on inhibiting the bacterial growth of Legionella pneumophila which isolated from different water sources, cooling towers, waterbath showers water and sewage water and identified by using the primary and selective media.Then,the results showed that the bacteria cant grow in those concentrations of inhibitors which were subjected to it.
