Cell wall of Mycobacterium tuberculosis amplified numerous times by electron microscopy
Tuberculosis (TB) is an infectious-contagious disease transmitted primarily by air and can reach all organs of the body, but as the bacterium reproduces and develops rapidly in areas of the body with much oxygen, the lung is the main organ struck by disease.
The sneezing or coughing of an infected person throws in the air about two million bacilli that remain in suspension for hours
PROBLEM OF MODERN BACTERIAL RESISTANCE
Of the 100 million annual prescriptions (14 tonnes), 50% are unnecessary.
About 60% of the antibiotics used in the USA are used in agriculture (20 tons / year).
Currently, about 70% of the bacteria responsible for hospital infections are resistant to at least one commonly used drug.
