Environmental microbiology concerns planetary and human “health”. But it is not medical microbiology = how pathogenic microbes cause disease. How disease-causing microorganisms survive, evolve and spread in the environment is part of environmental microbiology but how they cause disease once they arrive at their “victim” and how their victim responds to the assault is not environmental microbiology, it is medical microbiology.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
