[Occurrence of helminths in slaughtered sheep in Upper Bavaria. 2. Relationship between fecal egg count and worm burden].

The relationship between the faecal egg count and the worm burden of the gastrointestinal tract of sheep was examined. Close relationships were found in strongyles, Trichostrongylidae (other than Nematodirus spp.), Nematodirus spp., Strongyloides papillosus, Chabertiidae and Trichuris spp.. Due to high percentage of false negative diagnosis from faecal examination, this relationship was in Nematodirus spp. and Trichuris spp. not as close as in the other nematodes. However, the results support the high diagnostic value of quantitative faecal examinations in sheep.
