Eimeria mitis, 2 strains, chickens, reduced intestinal absorption of glucose and L-methionine, reduced weight gain, depigmentation of plasma, gross lesions absent

Strongylus vulgaris, ponies (exper.), diethylcarbamazine did not prevent clinical or pathological changes due to migrating larvae, fewer adults recovered at necropsy from treated vs. untreated ponies

Parafilaria bovicola, field survey of insect vectors collected from cattle, bleeding-point on cows and prepatent period studies, experimental infection of laboratory-raised Musca autumnalis with third-stage larvae, transmission of third-stage larvae to calves (clinical and pathologic findings)

Sarcocystis suicanis, Georgia isolate, pigs (exper.), pathology, reduced growth rate of host

Parafilaria bovicola, cattle, epizootiology, results of questionnaire survey among cattle owners revealed that (i) condemnation losses due to parasite were overrepresented among animals that came from herds held on pasture the previous year, as opposed to those from farms with indoor cattle management only; (ii) statistically significant difference between affected and nonaffected herds with respect to age groups; and (iii) frequency of lesions showed seasonal trend: Sweden

Leishmania donovani, amastigotes from dog marrow macrophages, ultrastructure

Sarcocystis cruzi, newborn calves (exper.), correlation of development of Sarcocystis with the resulting lesions

Strongylus vulgaris, massive infections of nonimmune and immune ponies, pathogenesis characterized, blood chemical and peritoneal fluid values as possible diagnostic aids

Parafilaria bovicola in naturally and experimentally infected calves, pathological changes, comparison of lesions found during the pre-patent period with those found during patency, with object of estimating age of lesions by their macroscopic and microscopic appearance
