Life cycle of m.Leprae?

No such thing: Life cycles in biology refer to organisms that have different appearances and abilities in different generations. Leprosy bacteria grow best at cooler temperatures inside cells, and you will probably find them interesting; I have the idea that they are a modified tubercle bacillus that has lost much of its genome. But in spite of anything else you may read, all generations are the same, no cycle. ...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

Urgent! dr. Martin r,  TB heal 10yrs, last wk qtf-g+, nil0.13 iu/ml, mitogen-nil\u0026gt;10, tb-nil 4.3, active tb? Gamma globulin2.2, unshapen stool

TB: Active tuberculosis is characterized by fever, night sweats, chills, weight loss and dysfunction or inflammatory changes in the area of the body affected. You seem to be fixated on the possibility that you have this and it is very unlikely. If you continue to be otc about this either go and see a doctor or perhaps a psychiatrist or psychologist. Good luck. It is very doubtful you have active tb. ...Read more

Brain tapeworm, allergic to flagyl, has Crohn's as well. Expelled live worms after 1 month albendazole, is there a better treatment? How to eradicate?

Brain tapeworm, allergic to flagyl, has Crohn's as well. Expelled live worms after 1 month albendazole, is there a better treatment? How to eradicate?

Nerurocysticercosis: If this is Pork Tapeworm (T. Solium), a meta analysis of treatment compared albendazole with praziquantal, suggested that albendazole is the better treatment: "Albendazole versus Praziquantel in the Treatment of Neurocysticercosis: A Meta-analysis of Comparative Trials". PLoS Negl Trop Dis 2 (3): e194. http://www.ncbi.nlm.nih.gov/pubmed/18335068 Anti seizure therapy may be indicated too. ...Read more

How can you rid klebsiella in intestines? Took 10 days suprax (cefixime) for uti. Would this kill off the kleb. P? 2nd UTI since jan. W/ klep. P. Feces spread?

How can you rid klebsiella in intestines? Took 10 days suprax (cefixime) for uti. Would this kill off the kleb. P? 2nd UTI since jan. W/ klep. P.  Feces spread?

Normal flora: Klebsiella in the bowel is part of normal flora. But may become more resistant if antibiotics are used that attain high concentration in the bowel. If appropriate conditions that relate to a UTI such as poor bladder emptying, a foreign body such as a catheter, exist, the klebsiella in the stool can colonize the urethra and cause a uti. ...Read more

Can you tell me are epec, ehec, etec, and eaec extra-intestinal pathogenic e coli?

Can you tell me are epec, ehec, etec, and eaec extra-intestinal pathogenic e coli?

E. coli.: These are all different kinds of E. coli where the first E is always "entero" and the last two are always "E. coli." The second letter is what differs; hemorrhagic, toxigenic, etc. I'm not entirely sure what you mean by extra-intestinal E. coli though? E. coli are most commonly transmitted by a fecal-oral route as they reside in the intestine , but can infect other organs as well. ...Read more

Cdiff 4yrs ago - now have LUQ & soft/loose stools. CDIFF TOXIN/GDH W/REFL TO PCR Result: Toxigenic C. difficile detected
New infection or colonized?

Monitor: Once you have C. diff there is a reasonable chance you can be colonized. The criteria for infection include watery stools in excess of 3-4 times daily. The pain or discomfort is usually in the lower abdomen. Soft stools with a relatively low daily frequency usually are not indicative of C. diff. In summary, the presence of C. diff. in your stool in itself is not indicative of infection ...Read more
