The genome of the organism that produces the world's most lethal toxin has been revealed. This toxin is the major weapon in the genome of Clostridium botulinum: less than two kg is enough to kill every person on the planet.
pneumothorax. entry of air into the pleural cavity in sufficient quantity to cause collapse of the lung and consequent respiratory embarrassment. If it is unilateral there is a mediastinal shift with displacement of the heart to the other side of the chest. Breath sounds are absent from the affected side. Pneumothorax.
Pneumothorax. A pneumothorax is a rupture of the air sacs, or alveoli, in the lung. As the baby breathes air into the lungs, some of that air goes through the rupture and into what is called the pleural space or cavity that surrounds the lung.The air that enters this cavity puts pressure on the lung from the outside, squeezing and squashing the underlying lung, making breathing more difficult.s the baby breathes air into the lungs, some of that air goes through the rupture and into what is called the pleural space or cavity that surrounds the lung.
