depending on how long ago you had the test done, you might have TB, but give it some time. It also depends on if you have had the TB shot before
2 :
If it does swell and is large then you do have a problem... no swelling is normal
3 :
You need to go back at your appointed time (48-72 hours after the test was placed) and have it read. Reactions outside of this time frame do not count, nor do areas of redness. The only thing that should be measured at the appropriate time is any hard, raised area

Mycobacterium tuberculosis

Mycobacterium tuberculosis?
Im looking for detailed info on growing M tuberculosis; I know that Lowenstein-Jensen slants are used, but I can't find anything that says what they are etc. Links/refrences would be great. Oh, and no wikipedia: if nothing else i drew a blank there. haha. Im starting a research project in a few weeks for my degree, and im going to be looking for potential new targets for drugs, which is all the more important with the spread of Extreme drug resistance TB

Bacteria boy Try this location, and could you put in a PS Explaining what in the heck are you going to do with this culture of a deadly Bacterium? Possibly start your own epidemic? if you are let us know so we can buy stock in the company that makes the anti bacterial that is most effective http://www.personal.psu.edu/faculty/w/x/wxm15/Online/Bacteriology/bacteriology_lec00.

Mycobacterium - a genus of rod-shaped acid-fast bacteria. Tuberculosis - a specific infective disease caused by the bacteria ( mycobacterium). Some links or reference: 1. www sanger.ac.uk/Projects/m_tuberculosis 2. www micro.msb.le.ac.uk/video/mtuber.html
4 :
A good starting point is: Biosafety in Microbiological and Biomedical Laboratories, a joint publication of the CDC/NIH. Your next stop should be a major University Hospital medical library. The librarian will help you find the most recent publication on cultures and propagation and testing for drug resistance. Then visit the Hospital Lab where this is done.

Several media both solid and liquid have been described for the growth of tubercle bacilli Solid media contain egg (Lowenstein-jensen, Petragnini,Dorset egg medium Blood (Tarshis), Serum (Leoffler's serum slope), Potato (Pawlowsky) The medium most commonly used is Lowenstein Jensen's medium W/o starch. This contains coagulated Hen's egg, mineral salt solution, asparagine,and malachite green, the last acting as selective agent inhibiting other bacteria. Liquid media include- Dubos',Middlebrook's,Proskauer and Beck's. liquid media are generally not used for routine cultivation, but are used for sensitivity testing, chemical analyses and preparation for antigens and vaccines The bacilli grow slowly, the generation time in vitro being 14-15 hrs. Colonies appear in about 2 weeks, and may sometimes take upto 8 weeks. Optimum temp is 37 C and growth does not occur below 20C or 40 C.Optimum pH IS 6.4-7. On solid media M. Tuberculosis forms dry, rough raised irregular colonies with a wrinkled surface. They are creamy white, becoming yellowish or buff coloured on further incubation.They are tenacious and not easily emulisified. In liquid media without dispersing agents growth begins at the bottom,creeps up the sidesand forms a prominent surface pellicle which may extend along the sides above the medium. Diffuse growth is obtained in Dubo's medium containing Tween 80. Virulent strains tend to form serpentine cords in liquid media, while avirulent strains grow in a more dispersed manner

Is tuberculosis contagious

Is tuberculosis contagious?
My grandma just went to a specialist. He told her that she has pulmonary tuberculosis, and it is not contagious. She babysits my son on a regular basis. According to my research online it is contagious. They told her not to worry that they can take care of it with antibiotics. Is there any other forms that she might have that may not be contagious?

Yes it is..Tuberculosis is contagious..Pulmonary tuberculosis is just that..... Tuberculosis.... it's def contagious
2 :
it is, but only if you drink out of the same cup, cough and then touch. you know that sort of stuff.
3 :
It depends if it's latent or active. TB can lie dormant in people for many years without making them ill. If she's tested positive for the bacteria, but has no physical symptoms, she isn't contagious. However, if she has a cough or is sneezing (from active TB), then she can pass the bacteria onto others. Edit: People who have the TB bacteria in their bodies sometimes never get sick, but they are treated for them since they have the potential to become ill. TB can flare up something like 20 years after the first exposure.
4 :
It depends on the type of tuberculosis she has. If she has Latent TB it means it is inactive and not contagious. If it is Active TB then it is contagious

My girlfriend is scared. A tuberculosis question, please help

My girlfriend is scared. A tuberculosis question, please help!?
my girlfriend told me a few days ago that her two friends had visited someone in the hospital with Tuberculosis. When they came home, they spoke with my girlfriend, who was unaware they had visited someone with TB. After a small talk, the two friends told my girlfriend that they had visited someone with TB and that before they left the hospital, the doctor told them that since they visited the TB patient, they might want to be tested just in case they got it now! WTF???!!! THEN THE TWO DUMB BITCHES TELL MY GIRLFRIEND AFTER TALKING WITH HER!!!! We are all roomates in a house. However, the two dumb bitches live upstairs and my girlfriend and I live downstairs. The two dummies brushed it off and they said they aren't going to go get tested. My girlfriend is frieghtened now. I don't know what the hell to do. Should my girlfriend get tested or are we just overreacting? Do you think my girlfriend got contracted when The 2 dummies said they wore face masks when visiting. Please help

Tell her not to be scared, but to go the the health dept. or primary physician & have a TB skin test also called a PPD.
2 :
If the patient in the hospital truely had TB, he/she would have been in an isolation room. Vistors would be required to wear gowns, masks and gloves while visiting, and to remove them when leaving the room. It is not likely that any hospital would let a TB patient have random visitors, nor does their encounter with the "physician" sound realistic either. That kind of third-hand exposure should not put your girlfriend at risk. On the other hand, if your girlfriend is concerned, a TB test is a simple matter. You can get one from your doctor or a public health clinic.
3 :
her 2 friends were not infected from the patient so your girlfriend wasn't infected because TB is not transmitted by inhalation but by direct contact with sputum of patient with open pulmonary TB so your gf is totally free if she is afraid she can take rifampicin 300mg tablet twice daily for one week
4 :
TB usually results when contact with the infected individual is continuous over an extended time, like if you lived or worked with the person. Like mentioned above, visitors would be stictly advised to "suit up" before entering her room. It is very unlikely she could have caught this form contact with a person who had just visited the person with TB and they took the proper precautions, the other two girls would have to have an active case of TB to transmit the infection your gf. TB remains inactive in the body until the immune system is weakened for whatever reason or may never become active. If she is really worried she contracted TB she could be tested, it is a painless called a mantoux. A standard dose of 5 Tuberculin units (0.1 mL) is injected intradermally (into the skin) and read 48 to 72 hours later. A person who has been exposed to the bacteria is expected to mount an immune response in the skin containing the bacterial proteins. The reaction is read by measuring the diameter of induration (palpable raised hardened area) across the forearm.
5 :
Nice room mates! (not!) Just have your girlfriend go to a doctor and get a TB test done. I get one done every year. All they do is inject some serum under the skin on the underside of the forearm. She'll have to go back 48 hours later to have it checked. If there is no rash or marking where the serum was injected, then your girlfriend does not have TB. I would suggest for her to get it done ASAP because TB is serious. Good luck!
6 :
TB is transmitted through the air. A person with TB disease of the lungs or larynx can release droplets containing Mycobacterium tuberculosis (M. tb) into the air by coughing, sneezing, talking, or breathing. These droplets, called droplet nuclei, can cause TB infection if inhaled by anyone who shares air with the person who has infectious TB. For TB transmission to occur, three things are required, a TB patient, an air path, and a susceptible person. It is assumed that a single TB droplet may be able to cause infection. Therefore, unlike many airborne pollutants, TB has no safe exposure level. TB is relatively difficult to become infected with compared to most diseases that are transmitted through the air, such as measles. The source of TB infection may not be identified. Most TB transmission is probably from undiagnosed TB patients. The likelihood of TB transmission occurring depends on the following three factors. 1. Source Patient Patients are not equally infectious. Depending on individual factors, such as the strength of the patient's cough, how watery their mucus is, and perhaps the particular strain of TB that the person is infected with. The most important patient factor is whether or not the patient is on effective chemotherapy. Effective therapy dramatically reduces the number of infectious droplets released by a patient. 2. Exposure Time The probability of infection is directly proportional to the amount of time spent in the high-risk setting. Usually, but not always, a person must spend a long time in the company of a TB patient before becoming infected. For people working in high-risk institutions, the risk is cumulative over time. That is, the more years you work, the more likely you are to become infected. 3. Environment The environment determines the path that TB droplet nuclei take after they have become aerosolized. This determines whether or not a susceptible individual can inhale these particles and possibly become infected with TB. Characteristics of the environment include the size of the space and the ventilation. Obviously, the smaller the space and the poorer the ventilation, the higher the risk. TB does not spread all that easily. The risk factor here is negligible, but if concerned see your GP and demand a test. If you live in fear of contracting something from these two that live upstairs, there's a great solution on this website and here's the coverage... The New Silver Solution product is the only patented engineered nano-silver particle product in the United States. Two U.S. construction patents have been issued. The unique SilverSol Technology(TM) now has a patented construction process [U.S.Patent #6214299], patented particle sizes and many patented end uses [U.S.Patent #7135195]. This patent covers a wide range of pathogens, including: Anthrax and the bacteria that cause Bubonic plague; and Viruses such as Hepatitis B and HIV; and, Parasitic diseases such as Malaria. The patent also includes more common infectious agents and ailments including MRSA , TB, skin infections, ear and eye infections, upper respiratory tract infections, STD's, and others.

I WOULD GET TESTED JUST TO BE ON THE SAFE SIDE, if a dr recommended they get tested they are STUPID for not being tested. it is very likly nothing will come out of it but better safe then sorry

Tuberculosis, Cholera and Dengue Fever effects

Tuberculosis, Cholera and Dengue Fever effects?
Hey everyone, I'm currently doing a biology assignment on Pathogens and their effect on humans as an organism. My chosen diseases/pathogens to investigate are Tuberculosis, cholera dengue fever in my chosen country India. I have to talk about whether the indigenous population, people who live in India, would be more affected by these diseases than those who traveled to India for a period of time. Having trouble finding information, so anyone who has even a small answer or suggestion would be greatly appreciated! thank you :)
