of the . / ' ■.

 part]. In biology, radiately divided. 



Actinomorphic [ak-tin-o-motf'-ik) [amis, a ray; 

 . form]. Same as Actinotnorphous.

 in 107c, a fungus : pi., Actinomycomataj. A tumor such 

 as is characteristic of actinomycosis. 



Actinomycosis [ak-tin-o-mi-co r -sis) [d/cri£, a ray ; u 

 a fungus], A parasitical, infectious, inoculable disease 

 lirst observed in cattle, and also occurring in man, 

 and characterized by the manifestations of chronic 

 inflammation, with or without suppuration, often re- 

 sulting in the formation of granulation tumors. The 

 disease is due to the presence of a characteristic micro- 

 parasite, the ray fungus, Actinomyces bovis, which is 

 composed of tine mycelial threads and club-shaped 

 bodies.- The most frequent and most curable form 

 is when the abscesses form about the jaws and teeth. 

 The best mode of staining the threads is by Gram's 

 method. To stain the clubs as found in man is diffi- 

 cult; the best results have been obtained with orange 

 rubin or eosin. The only treatment of the disease 

 is removal of the infected tissue. When the parasite 

 has found a nidus in the lungs or digestive tract, all 

 treatment is so far useless. The disease is often called 

 lumpy-jaw and holdfast.
