PARASITES 



chard (1885). Syn., Trichomonas irregularis, Salis- 

 bury (1868) ; Bodo urinarius, Kiinstler (1883). A 

 peculiar flagellate infusorian found in human urine 

 and vaginal mucus. — Cystotaenia mediocanellata, 

 Leuckart (1862). See Tcenia saginata, Goeze, 1782. 

 — Cytodites nudus, Vizioli. Syn., Cytoleichus sar- 

 coptoides, Megnin ; Sarcoptes gerlachi, Rivolta. This 

 is found in the air-sacs of the Gallinacea, especially 

 fowls and pheasants. They even reach the air-canals 

 in the bones, and are supposed to cause enteritis. — 

 Cytoleichus sarcoptoides, Megnin. See Cytodites 

 nudus, Vizioli. — Cytospermium villorum intesti- 

 nalium canis, Rivolta. Oviform, tetrasporous coccidia 

 found by Railliet and Lucet in the small intestine of the 

 dog and cat. See Coccidium bigeminum, Stiles. — Cyto- 

 spermium ziirnii, Rivolta. This was reported by 

 Proger and Ziirn from the intestine, liver, and glands 

 of calves. It is probably Coccidium perforans, q. v. — 

 Cytosporozoon malarias, Danilewsky. See Polimitus 

 malarice, Laveran. — Cytozoa pathogena. The 

 hematocystis of man and animals, found in malarial 

 and other fevers. See Polimitus malaria:, Laveran. 

 Dactylius aculeatus, Curling. See Euchytrceus 

 albidus, Henle. — Dasytricha ruminantium, Schu- 

 berg. A holotrichous infusorian of the esophagus 

 and stomach of ruminants. — Deer-tick, Western. 

 See Dermacentor occidentalis, Linne. — Demodex 

 canis, Tulk. See Demodex folliculorum, var. canis. 

 — Demodex folliculorum, Owen. Syn. , Acarus 

 folliculorurn, Simon (1842) ; Demodex folliculorum, 

 var. hominis, canis, cati, suis, avis, caprce, equi, 

 Kuchenmeister ; Demodex caninus, Tulk ; D. phyl- 

 loides, Csokor; Macrogaster platypus, Miescher (1843) ; 

 Entozoon follicularum , Erasmus Wilson (1845); Steato- 

 zoon follicularum , E. Wilson (1847) ; Simonea follic- 

 ularum, Gervais (1844) ; Simon et Simonide, Fr. 

 This is found in the hair-follicles and sebaceous glands 

 of several species of mammalia : dog, cat, pig, sheep, 

 goat, ox, deer, fox, rat, mouse, and bat. The derma- 

 tosis produced by this parasite has been most frequently 

 and best studied in the dog. Nearly every known 

 parasiticide has been tried for the cure of follicular 

 scabies of the dog, but generally in vain (Neumann). 

 Sulphur baths and applications of creolin or essence 

 of juniper have given fair results. — Demodex phyl- 

 loides, Csokor. See Demodex folliculorum, var., 

 suis. — Dermacentor americanus, Linne. The 

 American dog-tick. Cf. Ixodes ricinus, Linne. — 

 Dermacentor occidentalis, Linne. The western 

 deer-tick of the United States. — Dermanyssus 

 avium, De Geer. Syn., Dermanyssus gallince, Redi ; 

 Dermanyssus gallopavonis , Gervais ; Dermanyssus 

 hirundinus, De Geer ; Tique, Raspail. Gamasides 

 which live on birds and may be transmitted to domestic 

 mammalia : rabbits, dogs, cats, cows, and man. They 

 are found in dove-cotes and poultry-yards, and are 

 essentially noctambulatory. They frequently enter 

 the nasal cavities or auditory meatus. In nasal or 

 auricular acariasis, olive-oil, to which has been added 

 a little ethereal essence of anise-seed, should be intro- 

 duced by means of a thin feather. Oily mixtures, sul- 

 phuret of carbon and creolin are the most favored 

 remedies for the dermatoses produced by this insect. 

 — Dermanyssus gallinae, Redi. — Dermanyssus 

 gallopavonis, Gervais. — Dermanyssus hirundinis, 

 De Geer. See Dermanyssus avium, De Geer. — Der- 

 matobia cyanoventris, Moquin-Tandon. This differs 

 from Dermatobia noxialis, Brauer, in the azure hue of 

 the entire abdomen ; its habits are the same. — Derma- 

 tobia hominis. See Dermatobia noxialis, Brauer. — 

 Dermatobia noxialis, Brauer (i860). Syn., Der- 

 matobia hominis; CEstrus guildingi, Hope (1840); 



Cuterebra noxialis, J. Goudot (1845). A. bot-fly of 

 Central and South America, the eggs of which are not 

 infrequently deposited in the skin of animals and man 

 producing a swelling like an ordinary boil. In New- 

 Grenada this larva is know as Nuche, Gusano, or 

 Macaco Worm, in Cayenne as the Macaw Ely, in Brazil 

 as Ura, in Costa Rica as Torcel, and in Mexico as the 

 Moyoquil Worm. It attacks chiefly the ox and dog, 

 while mules and horses are exempt. In countries 

 in which the parasite is abundant, the skins of slaugh- 

 tered cattle are frequently so perforated as to be of 

 little value. — Dermatodectes communis, Bourgui- 

 non and Delafond. — Dermatodectes equi, Gerlach. 

 See Psoroptes communis, var. equi, Fiirstenberg. — 

 Dermatokoptes communis, Fiirstenberg. See Pso- 

 roptes communis, Fiirstenberg. — Dermatophagoides 

 scheremetewski, Bogdanow. See Symbiotes com- 

 munis, Verheyen. — Dermatophagus cuniculi, Ziirn, 

 1872. See Sarcoptes notosdres, Delafond and llour- 

 guinon, 1857. — Dermatophilus penetrans, Guerin. 

 See Sarcopsylla penetrans, Westwood. — Dermestes 

 lardarius, Linne. The larvae of this beetle, besides 

 devouring dead bodies, skins, leather, etc., develop at 

 times in the old manure of the dove-cote and attack the 

 young pigeons, gnawing the skin of the neck and abdo- 

 men. The best preventive measure consists in 

 covering the floor of the dove-cote and the nest 

 with pine sawdust mixed with sand. The larva; are 

 also reported as facultative parasites of man by Otto 

 and Chichester (England). — Dermestes murinus, 

 Linne. The larva is reported as a facultative parasite 

 of man by Otto and Lister. — Dermofilaria irritans, 

 Rivolta. See Eilaria irritans, Rivolta. — Dermo- 

 glyphus elongatus, Megnin. One of the plumicole 

 sarcoptidse found on the quill of the feathers of the 

 domestic fowl. — Dermoglyphus minor, Norner. 

 Syn., Analges minor, var. similis, Norner. This i 

 found in the quill of the feathers of the guinea-fowl. 

 — Dermoglyphus varians, Trouessart. One of the 

 Analgesina observed on the guinea-fowl, in the 

 quill of the beam-feathers of the large wing-covers 

 along with picobia. It is possibly only a variety of 

 Dermoglyphus elongatus of the fowl. — Deutscher 

 Blutegel. See Hirudo medicinalis, Ray. — Diacan- 

 polycephalus, Stiebel, Bremser, Rudolphi, Diesing.

 pel of the mulberry {Morns nigra), which had beei
