"482 Worms in the Intestinal Tract. 



due to H. perspicillum. Letulle & Marotel, in two dead pheas- 

 ants, saw subacute inflammation of the ceca, due to numerous 

 Heterakis papillosa. 



Symptoms. Tlie symptoms consist in o-radual emaciation, 

 feebleness, drowsiness, diarrhea, falling- out of the feathers; 

 pigeons sometimes die very suddenly, without any premonitory 

 symptoms. 



Treatment. It is similar to that given under tapeworm in- 

 fection; most advantageous are arecanut (chickens 3.0 gm., 

 pigeons 1.0 in pills), for pigeons also calomel (0.05 gm.) ; also 

 trochisci santonini, oleum anisi or oleum rosmarini (5-10 drops 

 in oil or as an emulsion), benzin (3-6 drops, same mode of ad- 

 ministration). For chickens one might mix with their food, 

 anis, salt, clay, also a weak infusion of garlic with i/47o of salicyl- 

 ate of sodium (Schlampp). 



The sick animals must be isolated and the droppings must 

 be destroyed.

(c) Dochmii in the Intestines. Dochmiasis. 



{Anchylostomiasis, Uncinariasis.) 

 (a) Dochmiasis of Carnivora. 



Occurrence. Dochmiasis is a severe affection, particularly 

 of packs of hunting dogs. It has, heretofore, been observed to a 

 large extent in France, Italy, Japan and Senegal, but it occurs 

 also in other countries. 



V. Ratz has seen the disease in Hungary among eleven dogs 

 from the same kennel ; Makoldy & Sequens have each one seen 

 a case in Siebenbiirgen ; the authors have likewise seen one case. 

 Cats are not as frequently affected. 



Etiology. Dochmii (Anchylostomum, Uncinaria) possess a 

 completely developed intestinal tract, a head bent backwards 

 with a horny capsule lining the mouth cavity, and the male has 

 at the tail end a bell-shaped, membranous, ribbed bursa. The 

 following two species are important : 



1. Dochmius trigonocephalus, whitish slender filiform worm; its mouth cap- 

 sule on the ventral surface is supplied with two chitinous plates, each one of these 

 has three while the posterior surface of the mouth capsule has two small teeth. 

 Male 9 to 12 nnn. female 15 to 20 mm. long; on the tail end of the male a three 

 folded bursa; the median fold is much smaller than the two lateral ones; ova (fig. 

 58) oval 74 to 84 fi by 48 to 54 fi, their contents usually divided in 6 to 8 seg- 

 ments. According to Eailliet this worm is identical with D. balsami found in the cat.
