I must admit that I am an absolute medical layman, trying to keep myself informed at best though.
Today I had a consultation at my dermatologist about a bad healing wound I have, to talk about the results of a swab they did last week.
It turned out that the wound is infected by several bacteria, and he said
Worst is that we found some gram negative bacteria ... (some other facts) ... , pseudomonas in particular.
Back at home I looked up what gram negative actually means, and found out to my astonishment, that it mainly (merely?) means the reaction of these bacteria in a coloring test.
Of course I looked up pseudomonas as well, and it's a fact that these are well known to be highly resistant to antibiotics (and my doctor explained that as well of course), and sometimes hard to medicate.
Now I am wondering, why he mentioned gram negative in 1st place.
Is it that the gram negative reaction in general indicates such hard to medicate, antibiotics resistant strains of bacteria?
Please excuse my laymans wording, I'm also not a native english speaker. Feel free to edit my question for better wording.
