Soil Bacteria Show High Resistance to Antibiotics
Miraba writes "Microbiologists have found that soil-dwelling bacteria are highly resistant to antibiotics, even ones that they've never been exposed to before. While this information suggests that superbugs could arise from these bacteria, it also provides the opportunity for testing new techniques in drug development for the future."
The specualtion about super bugs seems misplaced. So far antibiotics work quite well, albeit with limited lifespans of usefulness before resistance is induced. If dreaded "super bugs" were goinf to emerge from soils they would already exist or would have come about from these resistant bugs already. It has not happened.
Taking a wild ass guess I would be unsurprised if it turned out that the reason soil based bugs show such resistance is because some other bug is already using this antibiotic and they had to develop resistance to survive. For example, look at Penicilin which is naturually produced by mold presumably for this very reason: to kill bacteria.
So this has been going on millions of years before we came along. If a super bug was going to out there we would have found it already.
Some drink at the fountain of knowledge. Others just gargle.
Just like weeds picking up resistance to herbicides. With the rampant application of weed killer, we're actually breeding tougher weeds.
There's a reason they survive. It's because they're tough and adaptable. Sets up an interesting situation. We depend on modern herbicides and pesticides to maintain the food production it takes to feed a planet that's already over-crowded. But the weeds and insects we're trying to kill aren't sissies. At some point the chemicals we have to use to kill them are start going to take a toll on us.
Or maybe they already are.

According to TFA; the real danger is if the dirt bacteria cross with bacteria that can infect humans. They seem to imply that this is likely to happen and may have already happened (resistant staph infections).
Why this would suddenly come to light may have more to do with research funding coming up than any real danger. After all humans have been around dirt for a long time.
But I'm the suspicious type.
So, go ahead and have another serving of dirt;-)
When I took high school biology we learned that many antibiotics were developed from soil molds. So maybe soil bacteria are highly exposed to same fungi and have natually developed defences?
Fortunately soil bacteria stays in the soil and doesn't attack people very often.
Next topic please.
Bacteria might be resistant to antibiotics, but soap still kills them fine. All soap makes a great "anti-biotic", even the ones that don't say so. So if you still want to keep eating dirt, just wash your mouth out with soap - which would be a good idea in any case.
After all, otherwise you're going to be talking dirty all the time :-)
Now why anyone would want to eat dirt is beyond me. Is that what dirt farmers grow?
Let's call it what it is, Anti-Social Media.
If you research where antibiotics come from, where drug companies have for 50 years or more looked for new antibiotics, it's in the dang soil!
yes, scientists figured out long ago to not just set out pertri dishes and hope for new varieties of spores to come to them-- they've gone out into the world collecting soil and the concomitant spores. IIRC the majority of antibiotics in use were found in the soil of various places, all over the world.
Nothing new here.
... you just have to trust your immune system. The whole "hygienic" germ-free hysteria that our culture promotes (and which has been promoted for many years by many corporations that sell relevant products) is a self-fullfilling prophecy. If you don't eat some dirt as a kid, you won't ever develop the appropriate defenses.
/. readership is probably engineer-types, and that is engineer thinking. Biology is way, way more complicated. ;-) I feel like I'm one of the few biologists/ecologists here...
:-)
If you don't grovel around in the real world and exercise the ol' immune system, you'll have all kinds of allergies and asthma and whatnot. When I was a kid... oh, never mind. No, DO mind. When I was a kid, hardly anyone had allergies, or asthma, or ear-aches, or any of that crap.
Blanket overuse of antibiotics is exactly the same as pesticides and herbicides ending up with pesticide and herbicide resistant pests and weeds. You can't just make "negative" manifestations of nature go away like that. Most of the
Anyway, e.g., the polio outbreak of the 40's and 50's was actually due largely to too much cleanliness. Very young children would typically develop resistance to the (totally ubiquitous, endemic) polio virus in earlier times (via eating dirt), but "modern" notions of hygiene precluded this.
So, eat dirt or die!

I hate to belabor the obvious, but it's no wonder soil bacteria are resistant to antibiotics: they live in close proximity with the same fungi that evolved antibiotic chemicals to combat them. While we humans are doing a pretty poor job of judiciously using antibiotics and we are probably creating some real long-term problems by polluting the environment with antibiotics and disinfectants, we shouldn't forget that we didn't invent antibiotics, we discovered them. There are going to be lots of bacteria that are resistant to antibiotics simply because they evolved in an environment rich in fungi that produce them.
If you want to worry about antibiotic resistant bacteria capable of causing disease in humans, hospitals are a much bigger breeding ground than soil, which harbors innumerable species of bacteria that are harmless to us or even beneficial agriculturally, and only a few that can do us harm.

A few years ago I was working in my garden and my leg started itching, there was a small red dot mid-calf and minor swelling around it. I figured it was a bug bite. Within an hour the entire calf had turned red and was warm to the touch. I made a trip to Urgent Care and the doctor perscribed an anti-biotic and told me to go home and soak the leg in the hottest water I could stand. The next day I went into see my own doctor, by now my calf looked like an over-cooked hot dog and I was afraid the skin was litterally going to split open.
They drew blood and attempted to locate some pus to drain but found that it was not in sacks but more or less distributed though the leg (so the attempt to lance did not result in much drainage). I was given another kind of anti-biotic and was told to continue with the frequent hot water soaks. This time the anti-biotic seemed to help because the swelling started to reduce but soon enough, the swelling started up again and I found myself back in the clinic. This time my leg had started to lose it's pulse and my foot was grayish. They ran an anti-biotic in through an IV and had me elevate my leg for a few hours in the clinic. I was given another perscription and sent home with instructions to keep my leg elevated and to give it more hot soaks. I was told to come in to be checked the following day and to cancel any plans that I had for the weekend. These last anti-biotics worked and the swelling in my leg stayed down. The following day, I dutifully returned to the doctor and was told that had the swelling not shown such dramatic improvment, I would have lost my leg.
Through all of this, I never ended up in the hospital. I was treated with a barage of very powerful anti-biotics (the same exact ones that they use for "flesh eating bacteria") and my doctor told me that the bug I had was very closely related to that bug, he said that it was soil-borne and probably entered the skin though a bug bite.
I was even able to keep my weekend plans but I did not walk much and had to keep the leg up a lot (I went camping but not too far away). It took well over a year for my leg to return to it's normal color and I lost some tissue below the skin, these "things" are still with me (the best that I can describe it is it is like a scar underneath the skin, you can see some roughness in the skin and there is a different texture to the area but all the muscles and everything seem just fine.
I think my experience brings out the best and the worst of the HMO style medical system. I'm pretty confident that had I had a regular kind of insurance, I would have been in the hospital. On the other hand, the clinic was well staffed and had access to the right lab equipment and drugs to treat me. I'm glad it came out like it did and I really have to credit my doctors for everything that they did. They saved my leg.
