Abstract

In this epidemiological study 127 horses from five breeding farms in Upper Bavaria were included. The horses were coproscopically examined in intervals of four weeks over a 16-month period. Since 1992 in all farms regular prophylactic treatments with anthelmintics have been carried out. In 127 horses at least five species were established, such as Parascaris equorum, Anoplocephala perfoliata, Gasterophilus intestinalis and small strongyles, whose third stage larvae were characterized by eight or twelve intestinal cells. Infections with small strongyles occurred most frequently, followed by G. intestinalis, A. perfoliata and P. equorum. Seven horses excreted eggs of P. equorum, three yearlings, and a two, four, five and seven year old animal, each. 113 of the 127 examined horses showed infections with strongyles, hence, almost all animals of the farms I-V. The evaluation of horses with strongyle infections as regards to the frequency of the coproscopically established eggs revealed a high incidence independent of age. The maximal epg-values showed no obvious age-dependent differences varying between < or = 67 and 3733. The horses excreted strongyle eggs with epg-values of > or = 333 predominantly during the summer. With an epg-v...Continue Reading

Anthelmintics (ASM)

Anthelmintics or antihelminthics are a group of antiparasitic drugs that expel parasitic worms (helminths) and other internal parasites from the body by either stunning or killing them and without causing significant damage to the host. Discover the latest research on anthelmintics here.
