Why do these agar plates always have two intersecting lines on one side and nothing on the other side? Is it like an environment control thing?
Prove your humanity.

The standard way to streak a plate involves creating a resevoir of the sample you are studying, then using a sterile tool to streak through that at a steep angle. Then you streak through the first streak with another sterile tool, and so on and so forth.
As you streak through lines, the amount of bacteria pulled along is reduced until you are able to isolate individual colonies.

Normal flora can become pathogenic if it finds a way to a part of your body in which it doesn’t normally reside. For example, E. coli is NOT pathogenic when it’s in your lower intestines; different story when it finds a way into your bladder. …and even within the normal ‘home’ of a microbe in question, if your internal chemistry or immune system get out of whack, sometimes that resident flora can get out of control. This is basically ‘opportunistic pathogens’ in a nutshell.
So… every square.

Yeast infections of the vulva/vagina spring to mind as an example of resident flora getting out of control

Bad parseability is a bug in itself.

Looks like the raw output of a decompiler.

Computers are probably better on this than humans by now.

I happen to know that they infact are. One of the actual uses of AI.
Millions of images from specimens collected over decades have been fed into these nueral networks.
Essentially, when used for anything other than chatbots AI should do one specific job extremely well. This is because it is trained in the same manner as any human. You give it images of specimens and the diagnosis (bit more complicated than that, but it’s the important part).

I know some people from uni that made a startup doing exactly this type of stuff, they seem to be very successful. It’s impressive stuff, really.

Its a trick question, if there was a pathogen there the guy wouldn’t be holding it open like that haha… right guys ?
