STRONGYLINJE 



and the symptoms are finally terminated by death in a state of coma or 

 it may be in convulsions. 



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 yards should be 

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

 vermifuges recommended for dogs may be tried. 



Other Strongylinae. — Two other strongylines occasionally found in 

 sheep and cattle may be mentioned. 



1. Bunostomum trigonocephalum (Uncinaria cernua; Dochmius 

 cernuus). Strongylinae (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 dorsally. 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). 



Parasitic in the small intestine of 

 ruminants, particularly sheep and 

 goats. 



2. Bunostomum phlebotomum 

 (Uncinaria radiata; Dochmius radi- 

 atus). Fig. 157. Strongylinae (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. 

 (3/8-5/8 of an inch). 

 Parasitic in the small intestine of cattle.

Tracheal Strongylosis op Chickens. Syngamosis 



Two species of strongylines invade the trachea and bronchi of fowl, — 

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

 the larger and inhabits the air passages of water fowl.
