FAST FACT OF BOVINE TUBERCULOSIS
What is bovine tuberculosis and what causes it?
• Bovine tuberculosis (TB) is a chronic and debilitating disease of animals caused by bacteria called Mycobacterium bovis, (M.bovis) which is closely resembled to the avian and human tuberculosis causing bacteria. This disease is characterized by causing general state of illness, coughing and death.
• Cattle and buffalo are the main hosts of the bacteria.
• The name Tuberculosis derives from ‘tubercles’, which are present in the lymph nodes of affected animals.
• TB is a significant zoonotic disease (a disease of animals which can also infect humans).
• TB is a notifiable disease listed in the World Organization for Animal Health (OIE) Terrestrial Animal Health Code.
Where is the disease found?
• The presence of TB is throughout the world but disease is more prevalent in Africa, parts of Asia (like India) and of the Americas.
• The true hosts of M. bovis are cattle but disease has been reported also in many other domesticated and non-domesticated animals (buffaloes, sheep, goats, camels, pigs, equines a...
This extremely pathogenic zoonotic virus is now understood to travel from bat species, to equine intermediate hosts, to humans.[8, 10] The Hendra virus is listed as a Bio-Safety Level (BSL)-4, and can only be studied at a few adequately equipped laboratories worldwide due to its virulence.[1, 2] Case fatality rates

Normally, cows in Northern Europe in places such as Denmark live normal lives simply grazing on grass, and existing. However, there have been recent changes that have disrupted this normal activity. Generally the bluetongue virus (spread by Culicoides imicola, a biting midge) has been confined to Southern Europe and other places around the Mediterranean. But with the increase in temperature throughout the area, the midge has been allowed to migrate northward. This new pest is a nuisance and causes lots of difficulties to farmers in the area. When a cow contracts this disease, they usually also receive oral ulcers, salivation, stiffness, fever and eventually the inevitable- death (Merck Veterinary Manual NP). Because of the increase in temperature, midges have spread around the globe infecting livestock and creating terrible trouble for many farmers.
Signs and Symptoms of Active Tuberculosis Mycobacterium tuberculosis (MT) is a slender, rod-shaped, aerobic bacillus which causes tuberculosis. Tuberculosis (TB) is an airborn infection which is transmitted via inhaling droplet nuclei circulating in the air. These droplets are expelled from the respiratory secretion of people who have active TB through coughing, sneezing, and talking (Porth, 2011). Some bacilli stay in the upper airway and are swept out by mucus-secreting goblet cells and cilia on the surface of the airway.
Equine veterinarians are animal doctors who provide medical care for horses. They examine, test and occasionally operate on or euthanize the animals. Travel to ranches and farms is often necessary, and equine vets have to work outdoors in various types of weather conditions. Being an equine veterinarian is a pleasant career choice because of great interactions with varied types of horses and their owners , the basic information, and the pros and cons of an equine veterinarian.
Tuberculosis is a bacteria infection that affects many people over the world. Treatment for the disease helps people but it is limited. Vaccination is sought but, like treatment, is limited. Because of these limitations Tuberculosis spreads and kills easily. Tuberculosis can be cured by constant drug therapy.
TB germs enter the body, the immune system builds a wall around them. While TB
Exotic animals carry diseases and infections that can be potentially harmful or fatal to humans, jeopardizing the safety of the community. These diseases range in severity from common ringworm infections from African pygmy hedgehogs to lyssaviruses in p...
Tuberculosis or known as TB remains a leading cause of morbidity and mortality in the world, especially in developing countries. A combination of factors including high costs, limited resources and the poor performance of various diagnostic tests make the diagnosis of TB difficult in developing countries. According to Centers for Disease Control and Prevention (2014), one third of the world’s population is infected with tuberculosis. In 2012, nearly nine million people around the world become sick with tuberculosis disease, and there were around one point three million TB related deaths worldwide.
1. The specific organism should be shown to be present in all cases of animals suffering from a specific disease but should not be found in healthy animals.
Wear gloves and proper cloths if handling the infected animals to prevent the direct contact.
The purpose of this paper is to focus on a subject within my educational field that I can research and inform the public about. I plan to become a veterinarian .which would require my daily contact with humans and animals. Zoonotic diseases are risk factors that I have to be aware of in order to protect myself as well as my patients and their owners. Luckily developments in medicine have made it possible to cure zoonotic diseases and even prevent them from ever being contracted.
Tuberculosis is transmitted by inhalation of aerosols containing the tubercle bacilli. The required inoculum size for infection is usually high, but easily occurs with exposure to a patient who is currently infected. The products of dried aerosols, droplet nuclei, are particularly infectious because they remain in the air for an extended time, and upon inhalation easily move to the alveoli. The severe damage related to infection is caused by the reaction of the host. The tuberculosis infection has two phases, primary and secondary.
Tuberculosis is an infection caused by Mycobacterium Tuberculosis, an acid-fast Gram-positive bacillus, and “is characterized by progressive necrosis of the lung tissue” (Tamaro & Lewis, 2005). Tuberculosis is caused by many debilitating conditions like immunosuppression and chronic lung disease, among others. Nevertheless, human immunodeficiency virus (HIV), the virus that causes acquired immune deficiency syndrome (AIDS), remains the leading cause of tuberculosis worldwide. Tuberculosis can present in one of two types: active tuberculosis and latent tuberculosis. Prompt treatment prevents latent tuberculosis from evolving into active tuberculosis.
