128 POULTRY DISEASES 



BLASTOMYCOSIS OF THE GOOSE 



This condition has been observed by Martin. At autopsy 

 there were found small cysts attached to the capsule of the 

 liver. Tlie cysts varied in size up to a pea. They are seldom 

 if ever found in the liver substance. The cysts are yellowish- 

 white in color, fluctuate and resemble somewhat the small 

 echinococcic cysts. Upon microscopic examination yeast-like 

 bodies were found which somewhat resembled the Oidium 

 albicans. Some may be found in the process of budding. The 

 liquid of the cyst is of a yellowish color and of a gelatinous 

 consistency. The cells are provided with a capsule and con- 

 tain a homogeneous protoplasm in the center of which is ob- 

 served a nucleus. 



SARCOCYSTIS 



Sarcocystis is also called psorospermosis. It is dut to a sin- 

 gle-celled sporozoal parasite. It may affect the striped and 

 unstriped muscular tissue, connective tissue and at times the 

 visceral structures. 



Kuhn has described a sarcocyst as affecting the domestic 



fowl. 



CLOACITIS 



Symptoms. — The anus becomes red (inflamed), protrudes, 

 and later ulcerates. In a case treated in the laboratory anti- 

 septics were applied and injected into the cloaca with the 

 view of destroying the germs causing the trouble, but the bird 

 died. Upon autopsy it was found that acute inflammation 

 had extended the entire length of the rectum. See Fig. 2 for 

 this portion of the anatomy. The latter condition would be 

 called a proctitis. 



Hoare describes a contagious catarrh affecting the cloaca 

 and sometimes extending to the mucous membrane of the 

 lower portion of the oviduct and to the rectum. It may be 

 communicated from bird to bii'd by copulation. 



Treatment. — In these cases apply a solution of sulphocar- 

 bolates compound, five per cent carbolized vaselin, or a solu- 

 tion of five per cent carbolic acid in warm water. The solu- 

 tions may be injected with a syringe and the ointment applied 

 with the finger. 



The best results have been obtained by the injections of a 

 five per cent solution of sulphate of iron three times a day. 



PERITONITIS 



Acute peritonitis is rare. It may result from the irritation 

 that follows from rupture of the oviduct. It may accompany 

 aspergillosis or fowl cholera.
