Strep is a weird bug. We had some run-ins with it, mostly me & easy child at various times. Strep B normally lives in the throat and nose area and grows aerobically (ie with lots of oxygen). According to my microbiologist mate, when you culture strep that's been growing aerobically, you get largish patches of colonies.
Our problems happened when we got strep under the skin, growing anaerobically - without oxygen. Conditions had to be just right for this to happen - there were other bug involved (more later). But when this is cultured (usually only aerobically, since strep prefers oxygen unless it's had to adapt to manage without it), they often will report back a nil finding, even though they grew SOMETHING - because anaerobic strep tends to grow smaller colonies when cultured.
What happened with us - we got an initial staph infection. Everyone has staph aureus on their skin. People panic when you mention 'golden staph' but the REALLY scary one they mean, is the antibiotic resistant strains of golden staph (staph aureus). Pimples - staph aureus. But for easy child, and later me on a few occasions, we got a tiny break in the skin, so tiny you could barely see it. Staph entered, began to multiply and slight swelling immediately closed off the tiny opening. The bugs then, to survive, had to begin growing anaerobically, without oxygen. These can turn into really nasty, painful boils.
But the real nasty happens when you have somehow got a strep B infection in the same spot. These two bugs, growing anaerobically, begin to do nasty things. The strep actually moves into the tissues at the edge of the wound and soften it up. The skin begins to lift away at t his edge, which allows the anaerobic staph to move in as well. The swelling from the staph then gives the strep more room to advance.
Basically, this can quickly turn into something resembling flesh-eating bacteria. And because of the localised swelling, blood-borne antibiotics have trouble getting in to the wound area. Applying antibiotics topically is also difficult because the wound is still closed.
Nasty.
Now, this is still the gospel according to my microbiologist - to treat this effectively, you open the wound (it's blasted painful anyway) and drain it. Culture the muck and request that it be cultured aerobically AND anaerobically. They should also do a sensitivity.
Once it's been opened the swelling should reduce and the oral antibiotics should be more able to get to the infection. To help though, hot packs or hot salt water every three hours helps to dilate blood vessels and let the blood carry more antibiotics to the problem area.
I had to have surgery on my toe because I kept getting repeated anaerobic staph infections. Fortunately, I only ever once had the strep B associated with it and got onto it fast. easy child had a couple - one on her finger, which took some time to recover. Nothing for fifteen years.
Whenever you're watching surgeons on TV, especially makeover shows and the like, keep an eye out for the naughty surgeons who stick their nose above their masks. According to my micro mate, this is how strep infections can end up in surgical wounds - from being breathed out the surgeon's nose directly onto the surgical site.
Most of the time, strep infections will manifest as a sore throat, but these bugs are opportunistic, they will try to grow wherever they can, under whatever conditions they have to. If I could get it in my big toe, deep in the tissues...
These days a lot of pathology labs have automated as much as possible, even to reading the size of colonies grown. If you have concerns, don't hesitate to ask for a consult with the microbiologist who is in charge of the lab. You should at least be able to talk to him/her over the phone. It's saved me a lot of grief at times, to get the results confirmed (or otherwise) from the horse's mouth, so to speak.
Having a microbiologist as a neighbour was very useful at times! Entertaining, too, just not at the dinner table...
