Gram Stain (Overview)

The two major families of common bacteria are distinguished by the chemistry of their walls, specifically the ability of iodine to mordant their staining with crystal violet and prevent its being removed with strong solvent. Gram positives include staph and strep, while gram negatives include e. Coli. The stain has been in use for around 150 years and remains the most popular in bacteriology.

How does Dr. K know for certain that all these bites people describe as spider bites are MRSA if he hasn't cultured them or preformed a gram stain?

MRSA: Because there is an epidemic happening in the world. MRSA lesions are abscesses. Sitting at home with an abscess is unwise. MRSA has an appearance that is classic. And this classic appearance is described nearly identically by patients in my office, by email, online, and by the phone. Regular skin cellulitis or staph is not described as bites. Go to the doctor. Let them examine and test you. ...Read more
