How does doxycycline kill bacteria

Common Questions and Answers about How does doxycycline kill bacteria


Avatar f tn 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.
Avatar f tn 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!
Avatar n tn 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.
Avatar f tn I am getting worried now that the antibiotics may not have worked properly so was wondering if anyone could advice how long after taking doxycycline you start to feel better. My doctor did say see how I go after finishing them and if I'm still not good then go back to see him and he will contact the specialist to find out the next step (as he was honest and admitted he doesn't know much about lyme). I don't know whether I should go back sooner or give it a couple of weeks and just see.
Avatar m tn I got diagnosed with epididymitis a week ago and the pain has just now began to leave. Is this common and how long does it normally take for the pain to go completely away along with the swelling? My scrotum hasn't swollen and i've had a ultrasound, blood test, and urine sample and all came back negitive for cancer or a tumor. I'm really frightened about it and hope that this is just epididymitis.
Avatar m tn blot and ELISA tests are structured to look in your blood for *antibodies* made by your immune system to kill the Lyme bacteria, but there is a problem with this straightforward view: the Lyme bacteria can and do *suppress* the creation of the antibodies. Result: if the W.
Avatar f tn 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...
10506901 tn?1431354357 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.
Avatar m tn 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.
6402846 tn?1391067348 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.
Avatar f tn 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?
Avatar f tn My lumbar puncture test came back negative as well, but my test from Germany came back +14. What does that mean? How accurate is it? I attached a photo of my test result and hoping someone can explain it for me.. Can the test show false positives?
755322 tn?1330272714 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.
Avatar f tn The most important part of the treatment was finding a wise and experienced Lyme doctor who knew how Lyme and its companion infections operate and how to kill them off for good.
Avatar n tn 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.
Avatar m tn 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.
Avatar m tn 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?
1138687 tn?1360980244 Does anyone know the difference between Doxycycline Mono and Doxycycline Hyclate?
Avatar f tn 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.
Avatar m tn 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%?
Avatar n tn 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.
Avatar f tn 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.
Avatar f tn 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.
Avatar f tn 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.
Avatar m tn 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.
Avatar m tn 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.
Avatar f tn the Lyme bacteria are hiding in the biofilms, where the immune system cannot reach -- hence the need for biofilm-busters so the antibiotics can get to the Lyme bacteria and kill them. This understanding of how Lyme shields itself from the human immune system (thus requiring antibiotics to break through) is the basis of LLMD approaches to eradicate Lyme in patients.
Avatar n tn 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?
Avatar f tn I seen that both partners should be treated for urethritis so I went back to my doctors and got doxycline and she got doxycycline too but we have not had sex so that we can both kill the bacteria. I’m on my last day of the ten day doxycycline and throughout the 10 days the shiny bump felt like it had crust on it like it was healing like how a scab would be. 7 days into the treatment we just made out and I was wearing jeans and she was just feeling my penis vigorously.
