I'm so sorry to hear this, while I'm glad a diagnosis has emerged I feel somehow that I should have engaged more on this topic than it apears I have.

One thing I learned....blood cultures are typically grown only 5 days. These rare type of bacterial will take longer to grow, so if you or a loved one even just suspect endocarditis, please insist that they keep and grow the blood culture for 2 weeks to be sure! What a simple thing could save a life, because who's to say they won't be a "rare" case too!
yes if I hadn't mentioned it on your threads then I'm sorry, I thought I had. I've definately mentioned it for others recently (perhaps by email or PM). My surgeon was having an argument with my infection specialist when I was in having post operative infection surgery. The microbiologist said there is no infection. The Surgeon replied well you didn't see all the green pus I pulled out of his chest, so you are wrong.
I've posted before that P Acnes (or fully Propionibacteria Acnes) is commonly the culprit for prosthetics and commonly is ignored in the results due to there being an assumption that it is found in the culture as an accidental contamination from the skin surface.
Its incerasingly recognised as a major source of infection in prosthetics.
I would ask what antibiotic regime your son is on. I would urge you to suggest that he be on antibiotics longer and I would ask you to submit that he is placed on a combo of rifampicin and penecillin. If the bacteria has developed into a biofilm (which I mentioned in my above post and in my view it most assuredly has) then that combination will be the most successful at treating it. If you have not already read my post on my own struggle with this (which thankfully has not as yet infected the prosthesis that we know of) I suggest you read it:

Research papers in mictobilogy suggest that infections by Propioni require co-administration of rifampicin and penecillin to be close to 100% successful at clearing the infection.
For your information I remain on antibiotics to this day ... 500mg 3x daily of amoxicillin. Despite my urging on this matter the specialist treating me has the view that he want's to hold that back for "the nuclear option".
Yet no one has the confidence to stop my existing regime of treatment it in case it is actually still there. Based on my reckoning (and I will remind you that I was actually trained in this) it still is likely to be there there and so I will in all likelyhood be on antibiotics for the rest of my life.
For the benefit of other as well some of my previous posts warning people on Propionibacteria:

Propioni is often not identified early because:
1) it has a long culture time
2) often requires a multi pronged strategy to identify it with choosing a variety of culture mediums
one almost has to be specifically looking for it because its a slow grower
Anne, do not be duped by your team, they may say "its a weak bacteria" ... but they confuse slow growing with weak.
Anyway, I'm glad a diagnosis has emerged.
Best Wishes
as I've offered before, please feel free to contact me if you wish, although I'm not sure there is much more I can offer now.
