Anatomy & Physiology Respiratory #18
Which serious respiratory condition is caused by a bacillus pathogen?
Asthma is a respiratory condition manifested by bronchial spasm which leads to dyspnea. This condition is usually caused by allergic reaction or other forms of hypersensitivity, not a bacillus pathogen.
Influenza is a highly contagious viral, not bacillus pathogen infection of the respiratory passages. Manifestations often include body aches, fever, and a cough.
Laryngitis is an inflammation of the larynx, often caused by a viral, not bacillus, pathogen. Manifestations include harsh breathing, loss of the voice, and a painful cough.
Tuberculosis, or TB, is an infectious disease caused by a bacillus pathogen. Manifestations are caused by nodules that grow in the tissues of the body which most often impacts the lungs.
A respiratory condition is a type of disease that affects the lungs or other parts of the respiratory system.
Tuberculosis (TB) is caused by a bacterium called Mycobacterium tuberculosis, a bacillus pathogen. This bacteria often infects lung tissue and therefore respiratory function. Primary symptoms associated with TB include:
a bad cough lasting greater than or equal to three weeks
a cough that produces blood or sputum
pain in the chest.
