In Denmark anthelmintic resistance (AR) surveys have been carried out in sheep, goats, pigs and horses. Country-wide surveys carried out in 1993 in pigs, sheep and goats have revealed a number of new cases of AR in nematodes of these hosts. AR has so far not been reported in any helminths of ...

Management practices associated with certain production losses in cattle infected with trichostrongylids are discussed with particular reference to Denmark. Intensive parasite control may result in markedly increased animal growth. Recent research in dairy herds has shown that growth in excess of...

The serum IgG response of cattle with cysticercosis caused by Taenia saginata was studied in an ELISA in which a T. saginata metacestode surface extract was used as antigen. In experimentally infected calves, a sharp rise in specific antibody levels was found 3-4 weeks after the infection followed...

Evidence for the occurrence in Denmark of hypobiotic C. oncophora infections was obtained in parasitological and immunological tests on calves grazing pasture contaminated with O. ostertagi and C. oncophora. The animals grazed for 6 weeks from October, and were then housed. Faecal strongylid egg...

The case group consisted of farms from which cattle with low-grade cysticercosis had been detected at slaughter. The control group consisted of farms where no cases were detected during the same period. The major risk factor identified was allowing cattle to drink from streams carrying effluent...

Twenty-two Danish cattle farms were examined and stabled cattle were sampled for Pilobolus fungi in October and November, 1984. In laboratory cultures of faecal samples obtained from the rectum of cattle, viable Pilobolus spores were found in half the animals. Pilobolus fruit bodies were observed...

The distribution of Taenia saginata cysts was recorded in 23 experimentally infected calves. The calves harboured between two and 2569 cysts. A median of 15.7% of the cysts were located in the heart and 6.5% in the masseter muscles, the organs usually considered as the most important predilection...
