 ANI3IALS CAUSING BODILY HARM AND DISEASE TO POULTRY. 



I. By direct injury. 



Protozoa Cause false coccidiosis of liver [Amceha mcleagris), 



diphtheritic roup, epithelioma contagiosum. 

 Platyhelmia Tape worms often occur in all poultry (Davainea pro- 



glottina, Dreimnidotmnia infmidibuliformis and others). 



Nemertina None. 



Nematoda Thread worms (Heterakis) live in the intestines of fowls; 



the gape worm (Syngamus traclicalis, gapes). 



Chsetopoda None. 



Arachnida Sfocoji/ifZa; (depluming scabies, Sarcoptes Zajvis), scaly leg 



{Sarcoptcs mutans) ; ticks {Argas) ; mites (Dermanyssus 



avium) on skin and feathers. 

 Chilopoda and Diplopoda None. 

 Hexapoda Lice {Mallophaga), fleas (Pulicidm) and certain flies 



{Ornithomyia) and sand flies (SimtUium) cause 



annoyance. 



Mollusca None. 



Eeptilia Poisonous snakes attack poultry (chicken snake, Cohiber 



quadrivittatiis in N. America and others). 

 Birds Hawks (sparrow-hawk) and crows take the chicks; 



eagles, kites ; peregrine falcon. 

 Mammals Many mammals prey on poultry and eggs (fox, polecat, 



weasel, rat, Indian civet, leopard cat). 



II. -4s germ carriers. 



Chsetopoda Earthworms carry the ova and embryos of the gape 



worm and are eaten by fowls.
