Research Abstract |
Legionellae cause pneumonia in humans. Microbes that cause pneumonia usually live in the upper-respiratory organs and infect humans by droplets. In contrast, Legionella organisms are living in the environment such as surface water and soil. Hence, to totally understand Legionella infection, it is important to know how Legionella survives under environmental stress. One of their remarkable characteristics is their ability to grow in amoeba. They also have other abilities to survive in environmental stresses like low temperatures, low nutrition, etc. In this study, we tried to elucidate(1) the molecular mechanism by which they are able to grow in the amoeba at low temperature,(2) glucose metabolism which enables intracellular growth, and(3) micromillieu for intracellular bacterial growth in the host cells.
