How does doxycycline kill bacteria

Common Questions and Answers about How does doxycycline kill bacteria


hello, everyone~ so, i was reading burrascano's treatment guidelines re: antibiotics which i thought were interesting. i found the following passage: --begin quoted material-- There are four types of antibiotics in general use for Bb treatment. The tetracyclines, including doxycycline and minocycline, are bacteriostatic unless given in high doses. If high blood levels are not attained, treatment failures in early and late disease are common.
I am aware that people have allergic reactions to Lyme bacteria, so you see why I am confused. Does the fact that this reaction happened so quickly make it unlikely it is a herx reaction? Just would like to know other people's thoughts and experiences. Thank you!
I'm still not sure (my fault, maybe) if you only took doxy for 10 days or if you finished it 10 days ago "hello cave76 i have finished my medications only 10 days" But going under the assumption that you took doxy for ONLY 10 days----- then if it were me I'd be more concerned with the fact that I was under-treated.
Finally, I started noticing that I had to eat at least every two hours or I would get really lightheaded, and because I was nauseous a lot I had to force myself to eat. So that's how I felt from May to September with gradual improvement. In October, November, and December I felt better but hit a plateau. The main symptoms that lingered were the off and on lightheadedness, needing to eat frequently, on and off nausea, and gas pains. Then in January I started getting slightly worse...
otherwise, the Lyme bacteria hide in your body where the immune system cannot find and kill the bacteria, and so it becomes chronic. Other meds are then needed to break through the 'biofilms' the Lyme bacteria create to hide in, and those meds do not include doxycycline. In addition, about half of all 'Lyme' patients also got other infections from the 'Lyme' ticks, and each of those needs to be diagnosed separately and often treated with different antibiotics.
I am a 20 y/o male, whose been having health problems for 3 years. I have muscle swelling (inflammation), muscle twitching, brain fog, swallowing difficulties, balance problems, and fatigue. I don't ever remember having the characteristic bullseye rash. I've been tested for everything under the sun including Lymes (Though I'm not sure how accurate the tests in Canada are). I'm really not sure what is going on, But I was hoping someone who has been through something similar can maybe help.
It doesn't actually work for everyone, despite the treatment guidelines that say it does. Are you seeing a LLMD? How long have you been on the Doxy? How long have you been sick? All these factors matter. If Bartonella tests are negative, there are some anti-Bart herbals that can help figure out if Bartonella is present. An integrative LLMD can prescribe one or more of them to find out.
Somedays I cannot even get around. I haved asked many doctors if this stays with you or does it go away? Never got a straight answer. Does anyone know?
Lyme bacteria have the trick of hiding in areas of low blood flow, such as cartilage, where the immune system does not detect and kill. Also Lyme can form slimy shields called 'biofilms' in the body, where they also hide and do their dirty work. Piercing the biofilms requires a separate antibotic such as Flagyl, along with a regular antibiotic to then kill the exposed bacteria.
Then it appear a bacteria in my urine called enterobacter cloacae. My doctor prescribed me the antibiotics that can kill the bacteria, but when i made my last exam, i just got in the urine culture. My doctor said that it was very strange, so he wants to make me a citoscopy. I went to another doctor, and he made me a rectal exam and he found my prostate gland with imflamation.
I have to say, respectfully, that their treatment is not what I would want for myself, knowing what I know now about Lyme. A too small dose will just kill off the weakest bacteria and leave the strong to hide and come out later. (That's a bit over-simplified but gets the point across. That's why the best Lyme specialists here start with a very high dose and continue it for a long time.
Another thing that maybe helpful to some people is to realize that Azithromycin and Doxycycline work by not killing the bacteria, but actually by preventing the bacteria from reproducing. That means that your body's immune system actually has to kill the bacteria on its own. So for some of us this may take longer than others, and the bacteria may be present but not replicating after 7 days which may be why some of us still feel the symptoms. This should eventually go away.
I forgot to mention...doxycycline does indeed kill Lyme spirochetes, but it doesn't kill them when they are hiding in cysts or biofilms, which develop several months or years after initial infection. Because of this, it is often used by LLMDs in conjunction with other antibiotic(s) if you've had it more than a few weeks. I think that 200mg a day is lower than what is usually prescribed for Lyme. Did you feel any different when you started taking the doxy?
Does anyone know the difference between Doxycycline Mono and Doxycycline Hyclate?
i was reading the paper that comes with oracea~doxycycline and it says it doesnt kill bacteria now im getting worried because minocycline does kill bacteria now im worried i will break out more from the says its for rosacea but doest oracea work to kill acne to or no?and the differin gel 0.3% isnt this not as strong drying to dry up pimples as retin a micro 0.1%?
Bacteria on the skin feeds off this excess oil, blocking the pores and resulting in inflammed spots. Doxycycline will kill acne-causing bacteria on the skin and can be used in conjunction with Retin-a. Best Wishes, Eloise.
One of the main points to understand about bacteriostatic antibiotics [that is, those that stop bacteria from reproducing but do not kill the bacteria] is that they are usually effective in debilitating bacteria only when bacteria reproduce. "This is significant for two reasons. "First, it is believed that dormant Lyme bacteria don’t reproduce, which diminishes bacteriostatic antibiotic’s effectiveness in fighting Lyme disease.
My LLMD and LLND said that once a patient is asymptomatic for 3 months they stop treatment and the belief is that your own immune system has been built back up enough to continue the fight on its own, as it does with other bacteria on a daily basis. I know there are some of you who don't agree with that.
I agree with kathloj -- you could be 'Herxing', because as the antibiotics kill the Lyme bacteria, the dead bacteria release a bunch of chemicals etc. that are irritating to the human body. That reaction usually isn't REALLY awful, and it described in books as 'a temporary intensification of symptoms'. It means that the antibiotics are working, which is good, but if they are working too much and giving you really bad side effects, then the doc should be notified.
They did a strep swab, which was negative. The doctor gave me Doxycycline 100mg 2x/day for 10 days. Taking the Doxy I noticed my symptoms improved, however after a while my throat symptoms were not getting much better and seemed to stagnate. On 1/2 I saw my primary doctor and told her about the encounter. She ran a NAAT urine test for gonorrhea and chlamydia, and throat culture. All came back negative.
You are having trouble letting go of the idea that you have syphilis and it appears that my answers only fuel your concerns. This will be the last answer. The RPR a 6.5 weeks is highly accurate for syphilis, once again indicating that you do not have syphilis. Doxycycline for syphilis treatment is recommended at a dose of 100mg twice daily for 14 days. End of discussion.
Weirdly enough the onset took place after having a calzone and pizza. Does any think that it could be caused by the doxycycline, has anyone heard of gastritis from taking an antibiotic for such short period of time? -- I was prescribed Prevacid. If eat something "fattening" the pain does not travel all over like before but rather stays stationed on the left upper abdominal region.
My doctor said it burns when I stand because all the weight is pushing down but I do not feel comfortable with that explanation. 1.How long can the antibiotics usually take to kill the infection? 2. Is 15 days from the root canal enough even thought I have been taking for a long time prior to the root canal? 3. Why the burning only when I stand or walk? 4. What is your opinion of bee pollen for prostate health?

isi it possble not to have gonorhea if the result is only weak positve for chmlydia? her boyfriend gave her 2g of ZINNAT Cefuroxime to kill the bacteria, and she will take it for 2 days , 1g each day, now does it mean her chmydia is gone or cured? but before she wen to her doctor her boyfriend gave her this tablets, then when she got the result that she is postve for chmydia the doctor gave hera presciption of Doxycyline 2times daly for 7days... now what if (WHAT IF..
I don't know, but cutting down on the meds dosage gives the bacteria the chance to be only weakened and not killed, so the bugs that survive are developing immunity to the antibiotic. Not good. The saying "What doesn't kill you makes you stronger" applies to bacteria too.
This is the recommended dose for gonorrhea and twice the recommended dose for doxycycline. 2. I don't understand how, after having chlaymedia, which is not nearly as severe symptomatically as the clap, you can state that the severity can be low to high IN ME specifically. I've had NGUs before which were of the low severity in symptoms that I currently have and chlaymedia once which was SEVERE.
Low back pain can be from many reasons including the muscles, intestines, kidneys, pinched nerves and other causes. Antibiotics commonly kill good bacteria in the intestines leading to overgrowth of a bacteria called clostridium difficile which results in a watery diarrhea. It can happen right after or long after taking antibiotics.
Antibiotics would remain in your system for a day or two. However, you can only kill a bacteria once. I'm not sure you are asking this question. 2. In cases of epididymitis without obvious urethritis, does the std bacteria remain in the urethra and is thus detectable via urine test? If you had STI-related epididymitis (and I am not sure you did), the offending bacterial would be detectable in your urine. 3.
Due to concern about untreated STD (seemed like urethritis/chlymidia), I started a regimen of doxycycline (100mg 2x daily). I know it is not smart to self-treat, but benefit of early intervention seemed to outweigh risk of later treatment. I had taken 3-4 days of doxy by time of doctor's appointment. I was feeling better but still a sensation of something being "off" in penis.
