Abstract

Bithionol sulphoxide at 50 to 70 mg/kg body weight was highly effective against Paramphistomum in naturally infected cattle in Bulgaria, achieving reductions in worm burdens of 96.5 to 100% in 3 small scale trials. At 45 to 70 mg/kg, bithionol sulphoxide reduced the intensities of anoplocephalid...

Abstract

Adult F. hepatica from cattle liver were incubated in Hedon-Fleig medium in the presence of 14C-adenine, at 38°C for 75 min. 4 labelled nucleotides of adenine - AMP, ADP, ATP and NAD were isolated. The highest incorporation of the label was detected for AMP; followed in decreasing order for ADP,...

Abstract

Cross-reactions occurred in gel diffusion tests between the antigens of spermatozoa from bulls and rams and of liver flukes (Fasciola hepatica and Dicrocoelium dendritium). Spermatozoa-agglutinating serum from cows also reacted with the helminth antigens. The possibility of a link between fluke...

Abstract

Oral administration of levamisole at 7.5 mg/kg to sheep reduced the number of animals infected with P. microbothrium by 15-50% and the total number of paramphistomes by 81.56-99.4%. Administration of oxyclozanide at 15 mg/kg to sheep caused reductions of 30-80% and 73.94-99.4%, respectively....

Abstract

Results of a long-term epizootiological study of parasitic infections in farm animals in Bulgaria are presented. The most important helminthiases in sheep are dictyocauliasis, gastrointestinal nematode infections, fascioliasis, paramphistomiasis, dicrocoeliasis and monieziasis; lung nematodes cause ...

Abstract

In Bulgaria, the efficacies of levamisole, oxyclozanide and these drugs together as Nilzan were tested against natural Paramphistomum microbothrium infections in cattle and sheep. Faecal examinations and selected autopsy results showed that levamisole at 7.5 mg/kg body-weight cured 15 to 50% and...
