intestinal parasites, dogs, prevalence, sex of host and neutering procedure, age of host, mixed infections, diagnosis by fecal examination

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 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

nematodes of catfish, seasonal variation, measurements of Paracamallanus cyathopharynx and Procamallanus laeviconchus compared with those reported from other fish species recovered elsewhere in Africa

helminth parasites and Oestrus ovis in Karakul sheep, seasonal incidence determined by slaughter of successive groups of tracer lambs each exposed on pasture for 33 days, recommended deworming programme, importance of moving sheep to new pastures immediately after deworming

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

Psoroptes ovis, calves, control with ivermectin, dosages and routes of administration; effect on Bovicola bovis; Otobius megnini not affected

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

Anaplasma marginale, morphologic characteristics of colonies in Dermacentor andersoni midgut epithelial cells

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