The diseases of poultry (1899) The diseases of poultry diseasesofpoultr00salm Year: 1899 112 DISKASKS OF POULTRY. PARAsrn;s of the cksophagus and stomach. The Dispharoius spiralis, a round worm about one-third inch in length is found in the oesophagus of fowls. A worm supposed to be of the same species is sometimes found encysted in the connective tissue around the oesophagus, crop, and proventriculus, also in the walls of the intestine and in the mesentery. The Disphar- ai>;HS nasutus, a worm about one-fourth inch long has been found in the walls of the fowl's gizzard. Iegros reported an epizootic disease caused by this worm in a poultry-yard where several breeds of fowls were kept, of which the Crevecoeurs suffered most severely. The affected birds became emaciated, were dejected, and died exhaust- ed without having lost their appetite. During their last days they were unusually voracious. The gizzard was studded with the Dispharagus nasiitus, some of which were entirely hidden in the substance of the mucous membrane, while others were fixed in it by one extremity, the other floating freely in the cavity of the organ. In certain places they were packed together in a compact mass. Fip. 24.—Hetcrakis pcrspi- cillum. [Asi-itris iiifhxa.) </, male, /', female, x 2.
