Bacteria become more virulent in a space shuttle?

Will bacteria become more dangerous if they travel in the space in a “weightless” environment?
Why would bacteria travel to space to start with? Obviously it could only happen in a space shuttle!

I found this story on the BBC web site

“Wherever humans go, microbes go; you can’t sterilise humans. Wherever we go, under the oceans or orbiting the Earth, the microbes go with us, and it’s important that we understand… how they’re going to change,” Cheryl Nickerson, from the Center for Infectious Diseases and Vaccinology at Arizona State University, US, told the Associated Press.

    that is so weird
    how possibly can the bacteria actually sense changes in the gravity & the surrounding environment

  2. RKA Says:

    Bacteria, being “living organisms,” have to sense their environment in different ways to respond to it accordingly. Sensing the environment is vital to bacteria and to all other living cells. It allows them to find food, to respond to the availability or lack of nutrients, to protect themselves from various dangers, etc…

    Although sensing is not a part of the Basic Microbiology and Immunology course, you may be interested in reading more about it:

    The story was concluded by(there is no vaccine available or Salmonella food borne infections in human)


    what about TAB vaccine?Isn’t it for Salmonella?

  5. RKA Says:

    this is a good point; let’s discuss it.
    What’s the TAB vaccine against? Which Salmonella species? Which diseases?

    Most likely the article is referring to Salmonella food poisoning rather than enteric fever.

  6. samarkabeel Says:

    TAB vaccine(typhoid and paratyphoid A and B)

    A suspension of killed typhoid and paratyphoid A and B bacilli.
