And a ring and elasticity; infection 15d ~ 18d, due to the large population of mites in the trachea, conditions became clear, pale yellow trachea start,
Covered with irregular black spots, elasticity is damaged, this time for the second phase of mite infestation; 27d ~ 30d after infection, the airway is not full
Same stage of mites, tracheal wall turned black and loss of elasticity become brittle, this time for mite infestation third stage.
