Guest guest Posted September 2, 2005 Report Share Posted September 2, 2005 , Are you saying that all Bb is going to basically respond the same way to all abx? With only slight variations possible? This would certainly make it unique among bacteria and to me would seem to make it a much easier organism to fight then, if it's that predictable, which we certainly have not seen to be the case. I know that people claim that in vitro testing can't always predict what will happen in vivo, but still, it would be such a huge help, IMO, to test your organism's sensitivity in a petri dish first, rather than using yourself as the guinea pig. I'd rather go with the abx that's killing a lot, than the one that's sitting there doing nothing, or allowing the bugs to multiply. penny > > Whoa, really? Where? Who are they?

Guest guest Posted September 2, 2005 Report Share Posted September 2, 2005 I conclude that those organisms' surviving the therapy is not due to acquired resistance. It is due to some phenomena which have not been demonstrated outside the host enviroment. , Bb Cysts, blebs, granules? The Brorsons' studies etc Plenty to show that spiros do have mechanisms to ensure survival under "adverse circumstances" ie in the presence of most abx in-vitro. They can then be "reborn" from their mutated forms. In-vivo they also "flagelate" their way to sequestered sites very quickly and from there they can re-circulate and repopulate whenever they choose to. But of course that's only hearsay, since me, myself, personally have not got my own equipment in my backroom where I can play microbiologist and then scream at people that what "I don't see(or don't know enough about!) can't "possably"(sic) make you sick".

Because there is some variation between strains in natural sensitivity (I forget just how much).However, I have three papers in which Bb was isolated from the EM rash site both before and after treatment of EM, and MICs were done for both the before-treatment isolate and the after-treatment isolate.

Guest guest Posted September 2, 2005 Report Share Posted September 2, 2005 Yeah, I'm not even talking about " acquired " resistance, although it seems mind boggling to me that Bb wouldn't do what every other bacteria does. Adapt. I'm talking about having a way to look at which abx are most effective in vitro before GUESSING which abx to experiment with in vivo (on humans). At least it's a starting point. Otherwise, you've got people on Rocephin or doxy, (which for years was the standard lyme treatment) before deciding they're not all that effective (and getting slammed by the CDC and government in the process). Are the drugs effective in the petri dish? If not, I wouldn't start with those drugs. It's not just Tony saying that the petri dish is a good place to start. Most abx research starts there. Every microbiologist I've talked to say it's the best place to start. Infectious disease docs DEFINITELY utilize the petri dish in guiding treatment. Why aren't we? Because we haven't been able to culture the organisms, or show direct causal relationships. We're trying to convince the-powers-that-be, that the invisible illness we're fighting really exists based on research that the- powers-that-be can't be bothered to read, or maybe can't comprehend. We'd have a much stronger case to present to the government if we could show which drugs kill Bb in the petri dish and how resistant they are to drugs. Right now, lyme treatment is pretty much a big, EXPENSIVE, experiment, in the CDC's view, with not much proof to back it up. We'd be smart to rally push for something visible and simple. Like cultures and abx sensitivities. penny > I > conclude that those organisms' surviving the therapy is not due to > acquired resistance.

Guest guest Posted September 2, 2005 Report Share Posted September 2, 2005 Yes, lab studies exist which justify the typical ILADS choices of drugs. Mouse infection studies are possibly a better model than pure culture studies, and this paper found some very large differences between the set of drugs that can cure a stricken mouse and the set of drugs that can cure a stricken test tube: http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=174684 Thing is, none of these mice had refractory lyme. They could all be cured (at least for the duration of the experiment) with the right drug, which is not what we generally see in humans. While there may be more, I'm personally only aware of one animal ever getting refractory lyme, and thats one dog (of 23 or something) infected by Straubinger. A good bit of doxy failed to cure the dog. My first guess would be that refractory lyme disease is an accident. There is some site where Bb can lodge as a persistence form, possibly within phagocytes, and this ability evolved to slow down eradication by the immune systems of bird, mammal, and reptile hosts. However in some hosts this persistence form is very poorly cleared and therefore accumulates greatly, which does not occur in most hosts. Something (efflux?) gives this persistence form nonspecific drug resistance like the intraphagocytic survival forms of chlamydia in ReA. Just a guess. If there is a pecularity of the human immune system that allows this sort of thing to take place, it may have been forged by selective pressures arising from the unique lifestyle of humans. Some say smallpox killed more humans in the historical era than all other diseases put together, so I am trying to learn about it, but its not that well known. Anyways it may be we have more than our fair share of disease because of our extensive contact with sheep, chickens, dogs, rats etc, which is unique, and alos our degree of intra-species sociality, which is uncommon. Some say M. tuberculosis got us by way of the cow, so domesticating the latter was possibly not an unmixed smooth move. We may also have on average different *types* of diseases than our mammalian ancestors, not just more. I dont think either possiblity can be verified; we sure do know it all about human illness patterns, but illness in mammals in nature cant be studied well because god comes for the sick lil animals real real fast, blammo. When I had hypoglycemic attacks last summer and couldnt think clearly enough to find my way out of the grocery store, thats about when I would have noticed a tiger chewing on my neck if it werent for this whole civilization thing, and how theyre not allowed in the grocery store. <pennyhoule@y...> wrote: > Yeah, I'm not even talking about " acquired " resistance, although it > seems mind boggling to me that Bb wouldn't do what every other > bacteria does.

Guest guest Posted September 2, 2005 Report Share Posted September 2, 2005 Nelly Bacteria don't have a brain they just respond to chemical scenario's. I would think your cells and other factors are responsable for what they are or ain't capable of doing.It's not like they jump into a corner of your stomach to avoid something-THEY CAN " T THINK.Bacteria once there requirements are met start to multiply and the more fuel they have the more they can multiply.They are very fickle organisms and can only respond to SCENARIO " S not think and move, just basically the laws of nature.Also some really bad bugs like streptococcus can't stick to anything but the throat.If I tenderised your leg and fed you toxins to make your cells more bacteria friendly you can get bad bacteria sticking and causing damage away from there designated sites. > OK, if you say so, but spiros do " move " (spiral?) their way into whatever they elect as an interesting and sheltered area. > > Nelly > [infections] Re: borrelia culture available > > > Hi Nelly > What your describing as flagella in your spirochetes, is not > flagella, it only looks like flagella, it's unwinding of strands off > the spirochete.

There ARE a few studies I " ve seen, and some scientists & microbiologists HAVE observed, and patients HAVE reported, and even our very own Hagrid, er, I mean Tony (who's hobby and passion happens to be playing with nasty bacteria) that organisms develop resistance to an antibiotic, but after some months will sometimes become sensitive to it again, both in vivo and in vitro. So, this may support some of what is saying in some way, that there's some other mechanism at work besides pure antibiotic resistance being acquired. penny Quote Link to comment Share on other sites More sharing options...
