Reemerging waterborne pathogen

Water is essential element for all living feature including microorganisms. Many microbes can survive and replicate in different type of water with minimal nutrients and can be transferred to humans. Therefore, water could serve as a niche for transmission of many infectious diseases. As the epidemiology of waterborne diseases is changing, there is a growing global public health concern about new and reemerging infectious diseases. New microbial pathogens have emerged, and some have spread worldwide. In the last decades, industrialization, population growth and climate change have influenced the water resources and new or reemerging waterborne disease. Some of the microorganisms that has reemerged are pathogens such as Legionella pneumophila and Francisella tularensis. They are both gram negative bacterium, and cause serious disease in humans. These bacteria are able to survive in different types of water by various mechanisms. They life cycle, adaptation to aquatic environment and human cells are peculiar and is still under intensive research. In this lecture the interesting aspect of environmental persistence, pathogenesis of the disease and mechanisms of infection will be presented.
