Distilled for clarity.
W4U, let's make sure there's no further confusion about this, all right?

Ok, I would certainly welcome that. It seemed you narrowed it down to the digestive tract only, but I have seen many references to good and bad bacteria inside our organs.
Perhaps I should use the term microbiota and microbiomes instead of bacteria, which tends to be a specific micro-organism?
I do want to be correct in this, I started a tread on this and am responsible for its general correctness. A daunting task......Please Register or Log in to view the hidden image!

If you look through that list, you'll see that everyone of those inhabits our exterior and/or our digestive tract.
They do get into our internals, but when they do, they make us sick, and our bodies defend themselves.
Beneficial microbiotics do not make us sick, they keep us healthy, but not by killing bad bacteria, i.e. virulence. They do not fight with other bacteria. They just crowd them out. It's part of the "quorum sensing" ability of all bacteria.

I'll stop here with this . It is getting too far removed from the OP question.
Love to discuss it more in Biology and Genetics under "Microbiomes".
Some bacteria are good; some bacteria are bad.
Some plants are healthy; some plants are poisonous.
Cats purr; dogs bark.
People undergoing heavy course of antibiotics have trouble digesting their food. "Intestinal flora" need to be reestablished.
Oh my god, how can you keep missing this?
All those locations are physiologically exterior. Including the stomach, intestine and rectum.
I am not missing this. I know the digestive tract is an exterior surface. But by that generalization so is the respiratory system. The point is that once inside the body these surfaces are no longer exposed to the exterior environment, and the microbiome creates its own environment, responsible for a host of different beneficial functions, affecting the entire health of the host. To reduce this to a mere surface function is short-changing the functional symbiosis between human cells and non-human bacterial cells.
The bacteria exist both on the outside surfaces and on the inside outside surfaces.
You are stating an absolute that is just not true. The majority of bacteria live in our digestive tracts, true, but not ALL.
And what about other organisms? Plant growth and resistance to internal and external infection, photosynthesis in leaved plants.
How is it that the Hawaiian Bobtail Squid has evolved an entirely new organ which houses live bioluminescent bacteria and flushes out dead bacteria in accordance to the circadian rhythm? Do they know something humans don't?
The squid uses the light properties of the bacteria to hide itself from predation, while it provides a completely separated nutrient rich safe environment for the bacterium, a whole new application of mutually beneficial symbiosis.
Can a mod transfer this discussion on microbiomes to my thread "Microbiomes" in Biology and Genetics, please. That's where it belongs.
Does anybody here own any tarantulas, spiders, or arachnids?
I'm very fond of cellar spiders, pholcids, which share my place.
We get some big spiders over the spring and summer here in New Jersey. In the house they are usually small and easy to catch and release outside. Spiders help kill the insect pests in your house, if they get in.
I recently saw maybe the biggest variety here in southern OH, in my shed.
That is cool! My favorite type of spider is the jumping spider. We have them here in New Jersey. I have read their venom is not dangerous to humans, should they bite you.
The dog/cat person thing had me thinking of it how I'm autistic and naturally less social, making me identify as a cat person/personality.
It was a nursery web spider! Big but possibly generally harmless. I like jumping spiders too, a lot because of how they seem harmless. That way with cellar spiders I like so much--having harmlessness and a cute type of helplessness, but yet not minding me much at all unless I accidently bump their webs, when they move away quickly. I liked to watch the small jumping spiders walking, and turning around a lot, on the orange brick walls of my parent's house when I was young.
But cats, when given the opportunity, will form creches where the queens share responsibility for the kittens. Barn cats have been found to have quite a complex society. Being semi-feral they have the option to leave if they wish.
I wonder how the male cats fit in.
Tom, ahem, come and go. Please Register or Log in to view the hidden image! But seriously, folks, toms float around the periphery, and learn to not too near the creche. They sometimes club up, but they can move across country when pheromones demand it.
