Broth and slant properties? I hope this is what you are looking for... Mycobacteria tuberculosis (M. tb) grows well on Lowenstein-Jensen media (LJ media), which is an egg based media that contains malachite green (among other chemicals) to inhibit other types of bacterial growth. It also grows well on a Middlebrook medium(labeled 7H-10 or 7H-11). It grows slowly, if at all, on Blood Agar. Colonies are non-pigmented, roughish and raised on the various media. Under a microscope, the colonies appear similar to a cross-section of a brain, or a cauliflower... For broths, M. tb grows best in Middlebrook (7H-9) broths, but can also grow in Sodium thiosulfate broths as well. Colonies have the same appearance as they do on solid media, although they do float in clumps in liquid media. M. tb grows at 25-37 degrees Celsius, although it prefers 35 degrees. Growth is enhances slightly with CO2, depending on the specific strain. Hope this helps! This info pertains only to Mycobacterium tuberculosis, other types of mycobacteria have different characteristics. Check the CDC website for pictures and further information: www.cdc.gov

Yes, they certainly should be! isolation precautions are always used in patients with TB. http://www.uphs.upenn.edu/bugdrug/antibiotic_manual/infctl%20tuber.htm
2 :
Yes, for active TB patients. TB patients are put on what is called Respiratory Isolation because TB is highly contagious. There are new strains out there that are resistant to drugs. In a hospital, people entering the room would need to wear masks to prevent infection. Obviously, they are in a private room. When leaving the room, the TB patient wears a mask. This is called reverse respiratory isolation. Note: TB tends to go dormant and form capsules in the lungs. Someone with this won't demonstrate the coughing/night sweating symptoms and aren't usually considered contagious

not sure what it is but i know its contagious dont share drinks or anything cause u can get it with his saliva
2 :
I'd be concerned about the TB more than the HIV too. However, since there are different strains, I'd advise you to contact your local health authorities for advice. You can often find them in the blue page sof the phone book or simply call a doctor's office, hospital or public library to find such a contact.
3 :
There is a likelihood of you catching TB. The method of catching it is through cough droplets, and you need to be in constant contact with the person. So if you have alot of contact with this person just Take care.
4 :
The HIV is not an issue on its own. The tuberculosis on the other hand is extremely contagious and is a airborne disease. If he does have a active TB infection he needs to go to a hospital. TB is nothing to joke around with. Also----- TB has to be active in order for it to be infectious. I was exposed years ago and to this day I will test positive for TB even though I do not have a active infection. A chest X-ray is how they diagonis a active TB infection. I hope this helps -Dan EMT
5 :
Get checked for TB,-- simple skin test (or blood test in some cases) is done; and, sometimes person might need a chest x-ray to r/o posibility of active pulmonary TB. If you were just exposed to active TB/ got infected, you DON'T have a TB disease yet and you are not infectious or danger to others. It changes when you get sick/develop active TB (depending on form). Your physician may offer a preventative treatment to kill TB bacteria in your body; that treatment is free in many states.
6 :
Unless you are having unprotected sex with him, there is no rik for HIV. You need to consult a Doctor about the TB as I would think there is a high risk there.
7 :
You need to (1) tell your roomate to get treatment for the TB as soon as possiable, I had tb back in 1998 it is highly contagious and you should avoid being around your roommate immeadiatlly. TB can become dormat with medication therefore making it non contagious, if your roommate refuses to seek treatment you need to contact your local health department and inform them of his or her status. It is illegal to knowinglly putting others at risk without informing them. In 2006 I found out that I was hiv+ and am extremlly carefull not to infect others and if your roomie takes precautions as to not infecting others there should not be any worries about catching HIV from them
8 :
You need to find out if it is latent (not contagious) or active (contagious). Active TB is such a big deal that probably the health department would have contacted you by now if you were exposed to it, but it is best not to assume that. Either way you should get a TB test, even if he is not contagious, because as a member of his household it is possible that whoever exposed him might have exposed you

Also, if the x-ray of this person is done later after a few years ,Is is normal to see scarring What is quantiferon test ? What will be the result of a quantiferon test done on a person prior treated for tuberculosis?

It will be positive for life.
2 :
I have TB, and I also went through the nine month treatment of Isoniazid. Although you go through that treatment, it is possible for TB to be come active again. And unfortunately, active or latent, you will always have a positive skin test. Chest x-rays must be done in order to determine if the infection has become active. I think you should talk to your doctor, or to whomever you were referred for treatment. TB is something that has to be reported to the CDC, go to their clinics, and build a relationship with them and ask them to put it in your terms, not their medical jargon. I've never had to go through the rest of it, so I'm not sure, and I'm also an RN, but not specialized in that area, but turn to your healthcare providers, talk to them. There are tests that can be done to determine if your strain of TB was a resistant strain, and there is different medication for that, however it is quite expensive. But get more tests! Talk to your physician! And best of luck!
3 :
You should never take another skin test. If the person had actual TB, it would be normal to see leftover scarring.
4 :
The QuantiFERONÂ®-TB Gold test (QFT-G) is a whole-blood test for use as an aid in diagnosing Mycobacterium tuberculosis infection, including latent tuberculosis infection (LTBI) and tuberculosis (TB) disease. it works by taking a blood sample that is mixed with TB antigens . If the person is infected with M. tuberculosis, their white blood cells will release IFN-gamma in response to contact with the TB antigens. The QFT-G results are based on the amount of IFN-gamma that is released in response to the antigens.
5 :
I had "Valley Fever" (Coccidioidomycosis) when i was 8. I've always tested positive for tuberculosis with the skin test. My work, after a positive test, had me take an x-ray to verify I was free of disease. I worked with children infant to twenty-two. When I have an x-ray I have to explain to technicians that the scarring is from when I was a child. A quantiferon test is a test to determine if you have tuberculosis. Since this test is a test that looks at the white blood cells within your blood system. I'd think that it wouldn't give you a false-positive. However I really do not know for sure. Best of luck and good health to you

Is there a drug-free way to get rid of tuberculosis

Is there a drug-free way to get rid of tuberculosis?
I had a TB test two days ago and I think it's positive (Red, itchy, swollen, bump, hard like a mosquito bite the size of a dollar coin). I go back to the hospital next week for my second test.. Is there a drug-free way to treat tuberculosis? ex. many cancer patients were cured by becoming raw foodists.

there is none. treatment for tuberculosis will take at least 2 drugs because there are a lot of different bacteria to kill. Multiple-drug therapy to treat TB usually involves taking four antibiotics at the same time. This is the standard treatment for active TB. The four most commonly chosen medications are: Isoniazid (IHN, Nydrazid). Rifampin (Rifadin, Rimactane). Pyrazinamide. Ethambutol (Myambutol). the first 2 will kill latent tb infection. to further enhance the effectivity of the first 2 meds above, Pyrazinamide is added on the regimen to stop cell division of bacteria. the skin test will tell you if you are infected (if, according to US specifications, the transverse measurement of your "bump" not the whole redness measures more than 10mm.) to confirm if you are contagious, you should undergo a PPD to check if your sputum contains TB. i hope this helps. i have tuberculosis myself and i've started the 6-month treatment for LTBI (latent tb infection)
2 :
Yeah, cowee's right. Don't take a chance with "herbal" remedies. They don't work and the TB just has more time to grow. TB was once a scourge that made people die a horrible death. Now the docs can sure it so it's not a problem for you at all. God bless

It seems to be a very serious illness. I have Googled and found many medical journals discussing this disease. I am not sure I am qualified to interpret what is written in them but I suggest you look it through and see what you can find http://www.google.com/search?q=ovarian+tuberculosis&sourceid=ie7&rls=com.microsoft:en-US&ie=utf8&oe=utf8 I also think your lady-kin is under medical surveilance and probably her doctors know all these answers and if she hasn't asked these questions maybe its time to go with her with a prepared list of questions. Good luck

what happens inside the body when infected by tuberculosis

what happens inside the body when infected by tuberculosis?
i keep looking up sites, but i can't find the results

Once the TB bacteria has been inhaled via a carriers saliva or mucus droplets the particles travel to the lungs where they can multiply and cause infection (typically pneumonia). The bacteria may then, if not resisted by the immune system through fibrosis (scar tissue), attempt to spread to other regions of the body but this bacteria grows quite slowly unfortunately it dies just as slowly as it spreads requiring months of antibiotics to ensure the infection remains dormant

How do you completely clean a house from Tuberculosis

How do you completely clean a house from Tuberculosis?

I do not know where you live so I have no idea what strain of TB you have in your area. What you should do it contact your local health department and ask them for a copy of their suggestions for cleaning a residence where TB was noted to be present. They have specific guidelines for the TB infections they see in the area. Great question and I hope you get the answer you are looking for.
2 :
You don't have to clean a hours from Tuberculosis. The germ doesn't hang around that long. So if it's been over a day, you don't have to try to kill the germ, it's already dead. No danger. You would have more of a chance of catching TB just waking down the street and someone with TB coughed on you. Even that way is not very likely. Besides, unless you have HIV most people have to have continuous exposure for a long time. My brother lived with me for 2 years coughing all the time, then we found out he had TB. None of us caught if from him even then. Most people can fight off TB before it starts if they have a good immune system
