Treatment. — As the disease usually attacks hunting packs in ken- 

 nels, and there is constant reinfection, treatment is, as a rule, not suc- 

 cessful. It is most important that care be exercised as to cleanliness of 

 the kennel. Where possible, the sick should be removed to other quar- 

 ters. Water and food should be given from buckets or troughs which 

 are thoroughly flushed out after each meal, and the j-ards should be 

 kept free from pools and nmd. As medicinal treatment, the usual 

 vermifuges reconunended for dogs may be tried. 



Other Strongylinae. — Two other strongylines occasionalh' found in 

 sheep and cattle may be mentioned. 



1. Bunostomum trigonocephalum (Uncinaria cernua; Dochmius 

 cernuus). StrongyliniP (p. 280). — Yellowish or reddish in color; 

 cuticle transversely striated. The 

 buccal capsule has a long dorsal tooth 

 projecting forward. The mouth is 

 surrounded by six papillae; cephalic 

 extremity curved dorsall}-. The 

 vulva of the female is near the middle 

 of the body. 



The female is 20-28 mm. (3/4-1 1 '8 

 inch) in length; male, 15-18 mm. 

 (5/8-11/16 of an inch). 



Para.sitic in the small intestine of 

 rimiinants, particularh' sheep and 

 goats. 



2. Bunostomum phlebotomum 

 (Uncinaria radiata; Dochmius radi- 

 atus). Fig. 157. Strongylime (p. 

 280).— Dark in color. The dorsal 

 buccal tooth is short; two ventral 

 buccal teeth and two subventral 

 buccal teeth or lancets. The cephalic 

 extremity is curved. 



The female is 24-28 mm. (15/16-1 1/8 inch) in length; male, 10-16 mm.

 Syugamus trachealis and Syn. bronchialis. The last named is somewhat 

 the larger and inhabits the air passages of water fowl.
