serum pepsinogen concentration, determination method, possibly useful in diagnosis of bovine and ovine ostertagiasis

Haematobia thirouxi potans, two methods described for laboratory rearing, adult flies can be fed either on a bovine calf or on bovine blood in vitro

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

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

Babesia bovis, nonviable tissue culture-derived antigens as vaccine in cattle, comparison with premunition

Cytauxzoon felis, susceptibilities of bobcats, 4 species of domestic farm animals, 9 species of laboratory animals, and 17 wildlife species to infection using infective material from domestic cats, Lynx rufus floridanus developed cytauxzoonosis with signs and lesions identical with those of domestic cats and died of disease, Lynx rufus rufus developed subclinical persistent parasitemia, results indicate that both species of bobcats may serve as reservoir hosts; sheep developed low persistent parasitemia without clinical signs, while other species of animals failed to produce evidence of cytauxzoonosis

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

Cytauxzoon felis, susceptibilities of (i) domestic cats to inoculation with infected bobcat blood and ground tissues; (ii) domestic cats to subinoculation with blood from cats having received bobcat blood; (iii) inoculated cats to subsequent challenge exposure with deep-frozen virulent inoculum of domestic cat origin; and (iv) eastern bobcat to reinoculation with various doses of virulent Cytauxzoon inoculum of domestic cat origin; additional experiments to determine if piroplasm levels in bobcats and domestic cats could be raised to maximize chances for further transmission of Cytauxzoon to domestic cats

oxfendazole bolus for cattle, spray-dried lactose quality as influencing in vitro dissolution and bioavailability

Eimeria christenseni, Trichostrongylus colubriformis, pygmy goats (exper.), effects of concurrent subclinical infections on liveweight; apparent feed digestibility; balances of calcium, nitrogen, and phosphorus; serum copper and zinc concentrations; and bone matrix mineralization
