| Abstract: | - Onchocerca gutturosa is reported in Danish cattle for the first time. Microfilariae were found in 38 (9.4%) of 406 cows that were 2 years or older.
- Microfilariae were not randomly distributed throughout the skin but were concentrated in the umbilical area.
- No difference in prevalence was observed between breeds of cattle.
- Most of the infected cows had grazed on fields close to streams that contained Simulium ornatum, the vector of O. gutturosa.
- Differences in preferred biting sites of S. ornatum from cow to cow were correlated with the arrangement of hair.
