Correct! Your turn.

List the 4 parts of the Viral Growth Curve and explain what happens in each step.

1. Lag - bacteria synthesize proteins and enzymes in preparation for growth.
2. Exponential growth/log phase - bacteria multiply exponentially, with death rates far outstripped by growth.
3. Stationary - due to lack of space, toxins, antibiotics, bacterial growth slows to 0 net growth.
4. Decline/death - Death rate exceeds growth, population drops.

That's describing a Bacterial Growth Curve. Although they are very similar, I'm looking for a viral growth curve.

TOTALLY MISREAD THIS AHHHHHHHHHHHHHHHHHH

1. Attachment/Inoculation - viral particles attach to host cell and prepare for penetration.
2. Eclipse - viral concentrations decrease because particles enter the host and begin hijacking the cellular machinery to produce more viral particles.
3. Maturation - viruses mature and begin to be released from host cell
4. Burst - virus induce lysis or escape the host, inducing a large spike in viral concentration. This is observed by the sudden onset of plaque formation.

This is an educated guess based off what you said about kidney failure and the shape of the cell. I actually found it on my DD notes and not my MM notes lol.

Is it enterohemorrhagic E. coli O157: H7 infecting a cell?

Yes, this was already answered. Apparently though, it's attaching itself to the intestinal mucosa.

Wait that's incredibly strange. Right after I posted that, the rest of the thread loaded, so beforehand I had no clue that that was already answered

Was this page open for a long time? It doesn't update automatically, and it would make sense if it refreshed only after you responded.

Lol didn't see your answer. That's correct... Your turn!
