110 PARASITOLOGY. 
BRONCHIAL AND PULMONARY STRONGYLOSIS. 
This condition is also called Verminous Bronchi- 
tis, or Verminous Pneumonia. 
In Bronchial Strongylosis the worms are found 
coiled in small balls in the bronchial tubes; their 
presence causes bronchitis and may occlude the 
bronchial tube. 
In Pulmonary Strongylosis the worms find their 
way to the air saccules and produce a like condition. 
Broncho-pneumonia may develop as a result of in- 
festation of both bronchi and air saccules. The 
bronchial type of the disease is most often found in 
the young animals, while the pulmonary form is 
found in the old ones. All animals are infested by 
their respective species of the genus Strongylus. 
Symptoms.—At autopsy, a few worms have been 
found in the lungs of animals that showed no signs 
of disease during life. The symptoms are slight at 
the commencement of an attack; there is a loss of 
appetite and an unthrifty appearance of the animal, 
and finally emaciation. There is arise of tempera- 
ture; accelerated respiration due to the plugging of 
the bronchi with worms and mucus. 
It is accompanied by a cough which becomes more 
painful as the disease progresses. In later stages 
the fits of coughing are accompanied with convul- 
sions, and the animal finally dies of suffocation. The 
animal may expectorate ova or larvae. Upon aus- 
cultation mucus rales may be heard; dullness may be 
noted on percussion. 
Treatment.—The. problem of medicating large 
numbers of cattle, sheep or hogs infested by the lung 
worms is somewhat difficult. In horses and asses
