| isospora neorivolta sp. n. from the domestic dog. | the endogenous development of canine isospora rivolta (mahrt, j protozool 14: 754--759, 1967) was compared with the development of i. ohioensis (dubey, parasitology, 1978, in press) in intestines of dogs. a new name, isospora neorivolta, is proposed for the canine i. rivolta because of developmental differences from i. ohioensis. the major difference between these 2 coccidia is their site of development. isospora neorivolta develops predominantly in the lamina propria of the posterior half of th ... | 1978 | 739301 |
