BIOL 252 Lab - 9-10-09

We learned a lot in lab today, and I specifically found new information about Staphylococcus and Streptococcus bacteria strains. One particular strain of Streptococcus would not grow on an MSA (mannitol-salt agar) plate. This is because there is a high concentration of salt within the agar. An area with a lot of salt content is not a good environment for Streptococcus to grow. This now makes sense why so many doctors and nurses recommend salt water gargles when patients test positive for Strep throat. I wish I was told this would actually kill the bacteria in my throat, instead it was only a suggestion (that would be good information for doctors/nurses to tell their patients).

I also found some interesting finds about MRSA (Methicillin-Resistant Staphylococcus Aureus) on the Associated Press website. For the first time, scientists have found dangerous strains of this particular Staph on 5 beaches throughout the coast of Washington. This is showing evidence of MRSA in other areas, rather than in hospital/clinic locations. This is also a hint where MRSA may grow and is more evidence for people to shower after swimming by beaches.
