Experimental infection with Angiostrongylus vasorum was conducted in Iberian slugs Arion lusitanicus. Initially, different size/age groups of juvenile slugs (small,0.5 g and medium, 0.5-1 g) were exposed to freshly isolated first-stage parasitic larv

Earthworms in pastureland may be exposed to residues of veterinary medicines excreted in the faeces of treated cattle. Possible sub-lethal effects of these drugs on life history characteristics are critical to earthworm populations, but there are no

Pristionchus maupasi, a soil nematode, was used to elucidate the potential ecotoxic effect of the two anthelmintics fenbendazole and ivermectin in cattle dung. The population growth of P. maupasi was greater in faeces from cattle harbouring active Pa

The disappearance of artificially formed dung pats of grazing cattle treated with sustained-release boluses containing either ivermectin or fenbendazole was compared with the disappearance of pats of untreated cattle through two successive grazing se

Published reports suggest that some species of earthworms may serve as paratenic hosts or even intermediate hosts for the pig parasite, Ascaris suum. This study was conducted to determine whether infective As. suum eggs could hatch and the larvae rem

An experiment was carried out in 1997 to test the efficacy of an isolate of the microfungus Duddingtonia flagrans against free-living stages of horse strongyles under conditions in the field and to assess the eventual effect of the fungus on the norm

A series of experiments was carried out to examine the effects of two different isolates of the nematode-trapping fungus Duddingtonia flagrans to reduce the number of free-living larvae of the bovine lungworm, Dictyocaulus viviparus. A laboratory dos

The potential of using fungi to prevent nematodosis caused by parasites with free-living larval stages is well documented today. In this respect Duddingtonia flagrans, a net-trapping, nematode-destroying fungus, appears to be the most promising candi
