This is a very old (relatively) research sample of lanthanum hexaboride. If that chemical name means anything to you, then you likely belong to the 0.01% of the living human population that has been privileged enough to have experience in the realm of electron microscopy, or possibly some other advanced technology involvingthe precise blasting of electrons.
Well-scrubbed hands. University of Buffalo researchers in New York published a study December 27 in the journal Infection and Immunity that found that Streptococcus pneumoniae and Streptococcus pyogenes can live on surfaces such as toys, books and cribs for weeks or even months.
In theory, the contagious period for pneumonia lasts about two weeks, although a person tends to be most contagious when symptoms are at their worst -- which is usually around day two to four of the infection. A person with either viral or bacterial pneumonia is contagious.However, that person's germs are more likely to cause an upper respiratory infection (such as the common cold or the flu) in another person than pneumonia.hese germs are usually found in the mouth and nose of the infected person. They can be spread easily to another person, either through the air or by touching a contaminated surface. Most often, they enter the person's body through the mouth, nose, or eyes.
