Does this still happen?
You can get DNA tests for under $100 these days. A commander could test everyone on a ship for a few grand. If the Navy has people's DNA on file, it would be even easier.
theres probably no way to get a non-contaminated sample of dna from literal shit. i am just talking out of my ass though, i'm not a scatologist
Why not? It doesn't need to be clean, just unique to the individual.
theres a trillion bacteria in there, how would you separate the human dna from the bacteria dna
e: it turns out you can get dna from poop, at least from what I saw from googling. crazy stuff
I think there are at least two basic techniques. You can isolate the human DNA and that will generally be isolated to a single person (ignoring amorous encounters). Or you could profile the entire gut biom.
If this is a carrier, you are looking at thousands of DNA tests and probably closer to $40,000 dropped to maybe find a match.
If it's a carrier it may cost closer to half a million. But that's a drop in the bucket compared to the insane operating expenses of a carrier.
It's also worth it to catch someone who's risking the health of an entire carrier.
Indeed. Fixed my maths error!
