TB is short for Tuberculosis, a serious, non-treatable disease in people and livestock. It is a chronic infectious disease that is characterized by nodules (tubercules) that may calcify or turn into abcesses. The disease spreads very slowly, and affects mainly the lymph nodes. There are three kinds of TB bacili: Human, Bovine, and Avian. Practically every species of animal is subject to one or more of the three kinds.
Symptoms may not show until the animal is older. There may be a gradual loss of weight and condition as well as swelling of the joints, particularly in older animals. If the respiratory system is affected, there may be a chronic cough and laboured breathing. Next to the lungs and the lymph nodes, the udder is most frequently affected, showing increased size and swelling of the supra mammay lymph gland. Other areas of infection are the genitals, central nervous sytem, and the digestive system.
Since there is no treatment that is feasible for animals, often the best alternative is to have them be put down.

Which microbe causes TB in cattle?
Mycobacterium tuberculosis
Why would culling badgers have an effect on TB control?
Badgers are blamed for carrying TB and passing it on to other animals, such as cattle.
What would happen to cattle if they caught TB?
The cow would pass the TB on to its milk and humans could catch if the milk wasn't treated. All cows that have TB have to be slaughtered and burned.
Why is TB in cattle a problem?
TB affects the digestive system which makes animals eat less and gain less. TB can also affect the lungs, reproductive organs, lymph nodes, and central nervous system. The cost of treatment of TB in cattle is too costly and impractical, plus TB is very contagious so animals must be quarantined. All cattle that are tested positive for Tuberculosis and any other animals that came in contact with that TB-positive animal either directly or indirectly must all be humanely euthanized. Usually this involves having the WHOLE herd euthanized. That is why TB is a huge problem.

What does the tb vaccination do?
The BCG vaccine contains a strain of mycobacterium bovis, which is a bacterium that causes tuberculosis (TB) in cattle. The bacteria have been altered so that they do not cause a TB infection but make your immune system produce antibodies. These make you immune (resistant) to the disease.
Why are badgers pests on the farm?
because the badgers have TB (Tuberculosis) and they pass it onto their cattle. If the badgers do get culled then the farmers won't have to worry as much about their cattle getting TB. Hope this has been helpful!! :)
How do cattle contract tuberculosis from badgers?
British farmers and successive governments have long believed that bovine TB was being spread by badgers and infecting the national dairy herd, and since the 1970s badgers have been culled by gassing (now ceased) and shooting in attempts to prevent this spread. Tests carried out by the Ministry of Agriculture in the early 1970s showed that TB was more common in badgers than in other species. In the first Badger Act (1973), meant that licenses had to be issued for the killing of badgers. However, there are various other theories concerning the transmission of TB to cattle, and badger culling remains a contentious issue in the UK. Research into the specific mechanisms of how cattle contract bovine TB from badgers and into normal levels of transmission when culling is not practised is scanty.
What is a disease of cattle or sheep?
Transmissible Spongiform Encephalopathy: Scrapie in sheep and Mad Cow disease (or Bovine Spongiform Encephalopathy), cows can get TB and sheep can get foot and mouth
How many years of scientific research was carried out in the UK into the transmission of TB in cattle by badgers before the scientists published the Bourne report?
about 10 to 15 years
