techniques to locate lesions and recover developmental stages of helminths from equine arteries, subperitoneum, liver, and lungs postmortem

Anaplasma marginale, several techniques used to determine effectiveness of stains for demonstrating colonies of Anaplasma in Dermacentor andersoni

Dirofilaria immitis-infected dogs (exper.), cardiopulmonary function before and after period of exercise training, dogs tolerated program without signs of congestive heart failure or further development of pulmonary hypertension

Babesia sp. in Hyalomma marginatum rufipes, laboratory transmission to susceptible cattle achieved both biologically (tick feeding) and mechanically (injection of infected blood), low pathogenicity, apparently not transmissible to horses

Taenia taeniaeformis, cats (exper.), parasite longevity and productivity

Ixodes matopi, ecological study (microclimatic temperatures and relative humidities recorded in 4 habitats; seasonal and daily activity patterns; distribution of larvae, nymphs, and adults in different habitats)

Trichinella spiralis, digestion of infective larvae is important constitutive mechanism of resistance in chickens that probably precludes transmission of infection by gallinaceous birds in nature

Rhipicephalus zambeziensis n. sp., all stages of life cycle compared with life cycle of R. appendiculatus, redescription of R. appendiculatus, attempts to cross breed these 2 species in laboratory were unsuccessful thus validating their taxonomic separation, the 2 species can live sympatrically

Draschia, Habronema, horses, cutaneous infection (summer sores), efficacy of ivermectin

Toxoplasma gondii, clinical disease in nonvaccinated dairy goats, protective immunity against clinical toxoplasmosis in dairy goats vaccinated with Hammondia hammondi but not H. heydorni, antibody to T. gondii in vaccinated and challenge exposed goats
