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

such places as ancient Rome, Egypt, India and China. 2 3 4 5 The disease can be caused by different mycobacterium such as Mycobacterium bovis, M. africanum, M. canettii, M. microti, and most commonly, M. tuberculosis; although the five are highly similar and are together termed the Mycobacterium tuberculosis complex (MTBC). Recently, two additional organisms. Mycobacterium pinnipedii and Mycobacterium caprae have also been implicated with the disease in humans. 6, 7 Members of the MTBC are gram-positive
BACKGROUND Types of Silica Crystalline silica may be of several distinct types. Quartz, a form of silica and the most common mineral in the earth's crust, is associated with many types of rock. Other types of silica include cristobalite and tridymite. Potential for Exposure During Construction Concrete and masonry products contain silica sand and rock containing silica. Since these products are primary materials for construction, construction workers may be easily exposed to respirable crystalline
Introduction: Tuberculosis is an infectious disease which causes millions of death in humans. In India approximately 500,000 deaths occurs now and then. TB is an air borne disease which is caused by Mycobacterium tuberculosis. Apart from M. tuberculosis, there are many strains of Mycobacterial species like M. bovis , M .africanum , M. microti, M. caprae , M. pinnipedi i, M. canetti and M. mungi. Together these species are known to be M. tuberculosis complex. The main target of tuberculosis is the lungs
The discovery of genome sequencing by Fredrick Sanger and his team of researchers in the early 70’s gave rise to one of the most empirical research methods that was ever to exist. This revolutionary research technique has allowed scientists to finally encode organisms down to their most basic properties; helping massively in our understanding of pathways, reactions and functions of organisms. The technique involves analysing the DNA of an organism’s genome and therefore all the genes that compose
The problem: Tuberculosis has been known to mankind since ancient times. Earlier this disease has been called by numerous names including ‘consumption’ (because of the severe weight loss) and ‘the white plague.’ Mycobacterium tuberculosis (the bacteria that causes TB), existed 15,000 to 20,000 years ago. In the 18th century in Western Europe, tuberculosis reached its peak with a occurrence as high as 900 deaths per 100,000.2 What is tuberculosis (TB disease)? Tuberculosis is a contagious airborne
Treatment for Tuberculosis Tuberculosis has many forms that can invade the body. Many cures involve drugs and multiple combinations of the drugs. Drugs are used in combinations because tuberculosis can travel to different parts of the body. One of the causes for the spread of tuberculosis around the world is the emergence drug- resistance strain. Tuberculosis can become resistant to most, if not all, of the drugs that are used to treat tuberculosis. Tuberculosis is a bacteria infection
(about 6hoursAnother way of acquiring Tuberculosis is by drinking unpasteurized milk, milk straight from cow, although this is not a common mode of transmission, it can be found in rural areas. Ingestion of contaminated cow milk transmits Mycobacterium Bovis, the animal form which is still potent enough to cause tuberculosis in humans. ). Tuberculosis transmission is affected by exposure, socioeconomic status of person, proximity, immune status of uninfected individual (%&&%&? CDC). Tuberculosis

INTRODUCTION Nature of the Bacteria Mycobacterium tuberculosis (M. tuberculosis) is the bacterium that causes the disease tuberculosis (TB). A distinctive characteristic of the genus Mycobacteria is the presence of a thick lipid-rich cell wall and resistance to the decolourization step of the gram stain (being acid-fast). The acid-fast characteristic of the M. tuberculosis is the result of a waxy, lipid-rich cell wall. The cell envelope of the tubercle bacilli contains a layer beyond the peptidoglycan
Microorganisms play an important role in our life: helps us to digest our food, decompose wastes and participate in various life cycles. They are diverse and have adapted to inhabit different environments including extreme conditions, such as hot vents under the ocean to ice caps; hence known as extremophiles. There are more microorganisms present in us than there are cells, and the various microorganisms are bacteria, viruses, fungi and protozoa. Many people associate microorganisms as death and
is currently infected with the TB bacillus. How TB Spreads: TB is a contagious disease. Like the common cold, it spreads through the air. A person acquires a tuberculosis infection by inhaling tiny droplets of moisture contaminated with the Mycobacterium Tuberculosis bacteria. The source of these droplets is frequently from infectious individuals who expel thousands of water droplets into the air every time they cough, sneeze, talk or spit. A person needs only to inhale a small number of these
