The discs certainly seem like they would speed up the diagnostic process by causing isolation of microbes within an area around the disc which can then be subbed vs. having to attempt to sub a colony that is underneath or surrounded by other bugs. Proteus mirabilis in a mix is the king of annoyances as far as isolation goes.
I always though MacConkey was a near equivalent of EMB. I’m just surprised because I’ve used EMB for years and across the country, though I can see the advantage of vanc chocolate agar, particularly in the isolation of Haemophilus and Gonococci, from a specimen area not rich in Lactobacillus.
The discs on primary plates are for diagnostic purposes. For example, the presence of the chloramphenicol disc will show up the presence of yeasts on plates which might be clogged up with bacteria, and as most bacteria are sensitive to chloramphenicol, it is quite useful.
Also, the hospital I work at don’t have EMB agar and instead use vancomycin chocolate agar for the selection of GNBs.
I know you don’t read this, wouldn’t expect you to, but I can’t help but ask: How does a person not care? True, I don’t really know you, but I know the pictures of the stories. I’ve seen them before and lived them before. To live life is to deal with problems, but sometimes the inability to see past the problem is worse than the problem itself. And when people sit and stare at a problem, it worries me. I see the glued up broken glass because broken glass is what I know. Broken glass is why I am who I am, and why I can cut those who come too close.
Changing looks doesn’t change who you are, and trust me I’ve tried many times with various masks from the classics of theater.
I obsessed over memories. I still do to a degree because I lost so much, but how can somebody move forward if they always seem to be looking back. But then again, I probably just displace myself on others, and see what I used to be, rather than what is. I focus on the weakness and fail to see the true strengths, because I don’t really see myself as having that strength.
At the end of the day, I feel stupid for how I said what I said, at the same time though, I honestly don’t know how not to be concerned. It’s never been my nature.
