Yeah, it depends on what strains you are culturing. MRSA is multidrug resistant, however if it is run of the mill staph, you have a better chance at treating it. Pseudo can be really tough because it has a slimy coat over the bacteria, thus making it hard for the antibiotic to penetrate. Also pseudo likes to clump together. I grow staph (not MRSA), PA, cepacia and steno....sometimes not all at once (always the cepacia and staph...the other colonies might be too low to detect but they are invariably there) , sometimes all at once. Depends on what is going on with my lungs. TOBI suppresses the PA to an extent, but then I find that the steno and cepacia colonies increase (both are resistant to TOBI). Interesting.....
