What tests can differentiate shigella boydii and shigella flexneri without doing serological tests?

What tests can differentiate shigella boydii and shigella flexneri without doing serological tests?

Shigella: I don't know how technical you want to get. Initially, culture will reveal one of the four shigella species. Then there are many laboratory protocols to separate them if necessary. One way is to use agglutination tests for each of the species. Check out appendix D of this manual: http://www.antimicrobialresistance.dk/data/images/protocols/gfn_shigellaserotypification-final-29-06-10.pdf ...Read more

Could plaquenil (hydroxychloroquine) for UCTD make me susceptible to Serratia marcescens and Stenotrophomonas maltophilia in two sinus cultures?

Could plaquenil (hydroxychloroquine) for UCTD make me susceptible to Serratia marcescens   and Stenotrophomonas maltophilia  in two sinus cultures?

Maybe but less likel: Plaquenil (hydroxychloroquine) is an immunomodulator and can certainly increase the chance for certain infections. I don't think it is a very significant amount of increase though. On the other hand, Stenotrophomonas tend to be seen in individuals that have had recurrent exposure to different antibiotics. I would guess you might have had recurrent sinusitis (or other infections) where you were treated with abx. ...Read more

Hi, if a person has scalp & genital myiasis, what is the protocol? Concern for intestinal infestation. Success w/ occlusion & Bactrim, (sulfamethoxazole and trimethoprim) not ivermectin.

Hi, if a person has scalp & genital myiasis, what is the protocol? Concern for intestinal infestation. Success w/ occlusion & Bactrim, (sulfamethoxazole and trimethoprim) not ivermectin.

Not invasive: Fly larvae need to be surgically removed by a medical profession. After removal, the wound is left open and should be cleaned well at least daily. Proper hygiene of wounds is very important when treating myiasis. Sometimes medication is given, depending on the type of larva that causes the problem. The fly larvae of myiasis remain just under the skin and do not move into other areas in the body. ...Read more

What are the tests for clostridium difficile infection?

C. diff: Both the bacterial toxin and the gene coding for the toxin can be found in the diarrheal stool. Additionally, the diarrhea has a peculiar mousy/musty aroma. ...Read more

Was advised by my doc to take bactrim (sulfamethoxazole and trimethoprim) as the parasite has a symbiotic relationship with bacteria. Ivermectin reduces symptoms. Request for a cure.

What parasite?: You have asked questions like this before but have not provided the name of the parasite about which you are concerned. Give more info and perhaps can provide a more specific response. ...Read more

What are the tests for clostridium difficile infections?

What are the tests for clostridium difficile infections?

Stool test: The most commonly used tests for c diff are two different stool tests. One test looks for the unique toxin which c diff produces that causes the diarrhea. The other test searches for the gene (dna) that is specific to c diff and encodes the information to produce the toxin. ...Read more

What are the tests for norwalk virus infection?

What are the tests for norwalk virus infection?

RT-PCR of stool: Tests for norovirus are not generally needed as clinical picture, self limited nature of disease and treatment don't require a specific diagnosis. If a diagnosis is required, reverse transcription PCR of stool is rapid and fast. Epidemiologists absolutely need to know who has what to prevent further spread and identify sources so PCR has a role there. ...Read more

Can 16s sequencing of my intestinal bacteria identify any/all of following infections: h. Pylori, c. Jejuni, toxoplasma gondii?

Can 16s sequencing of my intestinal bacteria identify any/all of following infections:  h. Pylori, c. Jejuni, toxoplasma gondii?

Yes but...: Dna sequencing can identify most of the bacteria and also the % of those present. What you are going to use this for is perhaps the most important question and where are they located? I would check with your physician, find out what testing facility they are using and how extensive is the test. Some of the test only look for a few of the bacteria and don't measure them all. ...Read more

Neg for gon/chlam 3 times as well as trich, hiv, syph, and uti. I suspect myco/ureaplasma. What is the best antibiotic course? No tests where I live..

Neg for gon/chlam 3 times as well as trich, hiv, syph, and uti. I suspect myco/ureaplasma. What is the best antibiotic course? No tests where I live..

NGU?: Ureaplasma is normal in the genital tract. So are most mycoplasmas, except M. genitalium. There are no approved tests in the US, but CDC has guidelines for Rx of NGU and M gen if doxycycline or azithromycin don't work. However, the symptoms you list as "conditions" are not those of continuing NGU if you don't have urethral discharge. Best to see an STD or infectious disease specialist. ...Read more

Can a combination of bactrim (sulfamethoxazole and trimethoprim) and flagyl cure an std?

Can a combination of bactrim (sulfamethoxazole and trimethoprim) and flagyl cure an std?

Depends on the STD: There are 20-30 bacteria and viruses that cause STDs. Some would be cured with these antibiotics but others would not. Only one, trichomonas, is reliably cured by metronidazole (Flagyl). Bactrim (sulfamethoxazole and trimethoprim) would work against some cases of gonorrhea or chlamydia, but not against anything else -- and it is not the best drug for any STD. Sounds like you'd better check back with the doctor who prescribed them. ...Read more

Will a cystoscopy with bladder stretching and tissue biopsy include testing for candida fungi and Lyme spirochetes in bladder? I have both conditions

Will a cystoscopy with bladder stretching and tissue biopsy include testing for candida fungi and Lyme spirochetes in bladder?  I have both conditions

Discuss with doctor: The individual performing endoscopy is the person to discuss the nature of the testing they plan to perform. I am not aware of anybody who examines for the presence of spirochaetes in the bladder, although if you insist upon this there are specialty labs which may perform this. It is not by any means a standard test, nor is it likely to be of any benefit in the management of your condition. ...Read more
