Leishmania donovani, dogs (exper.), liposome-encapsulated meglumine antimoniate (LEMA) vs. unencapsulated meglumine antimoniate, LEMA was 700 times more efficacious than the encapsulated drug, liposomes can markedly reduce the drug dosage required for equivalent treatment of visceral leishmaniasis

Amblyomma hebraeum, percentage and rate of female attachment to rabbits was higher (except shortly after release of females) around feeding males than in areas previously treated with extract of fed males, effect of elapsed time and of number of males vs. equivalent extract on attachment values, results prove bioassays to be valid for component and extract-equivalent assessment

nematodes, lambs, 11 anthelmintics compared using medicated feeds or multiple small doses

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

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

Fasciola hepatica, natural infections of cattle surveyed by enzyme-linked immunosorbent assay (ELISA), results compared with those obtained by fecal examination, advantages and limitations of ELISA for diagnosis: Washington

nematodes of ponies, efficacy of oxibendazole in paste formulation, 1-group critical test compared with 2-group control test

In 1973-1974, 4 controlled tests were performed in pony foals (n = 17) raised parasite-free and experimentally infected with Strongyloides westeri. Administration of infective larvae by stomach tube in 1 test resulted in low-grade infections and tended to invalidate the test. Intraoral and percutaneous (intra-aural) administration of larvae resulted in suitable test infections for 1 and 2 tests, respectively. A paste formulation of dichlorvos at 36.3 mg/kg of body weight removal from 4 ponies. Treatment of 4 the dosage rate of 44 mg/kg was consistently effective (greater than 99% to 100%) for eliminating intestinal infections of S westeri.

Amblyomma hebraeum, purification procedure used to obtain pure toxic components of tick eggs, characterization of toxin structure, histopathologic lesions observed in guinea pigs inoculated with egg extract or purified toxin, lesions in guinea pigs inoculated with crude egg extracts of 3 other ticks were histopathologically similar

Strongylus vulgaris, establishment of patent infections in 6 of 8 helminth-free ponies given adult worms via nasogastric tube, removal of worms from cecum and ventral colon of donor horses, initial appearance of eggs in feces and maximum egg counts of recipients, percentage survival of adults after intragastric inoculation determined at necropsy
