Cyathostominae, also called small blood worms, is the name of an underfamily of the order of the Strongylida (worms). It is a collective name for a group of parasitic worms that live in the intestines of horses. They are among the most common gastrointestinal worms in horses. Description
The lower family of the small strongylids or Cyathostominae consists of at least 50 species of which 10 to 12 are common. The life cycle begins with infected eggs released from the stool of horses. This egg can not be distinguished from that of the large bloodworm. Infectious larvae can survive in the pasture environment for six months, depending on temperature and humidity. When grazing the larvae are taken into the intestines. The entire development of larf to adult worm takes place within the intestinal wall and cavity. Thus there is no migration through the intestinal arteries as in the large bloodworm. However, migration occurs within the intestine. Therapy
Horses in infected meadows must be treated preventively in November-December with the anthelminthicum moxidectin; Other worms do not work against larvae encapsulated in the intestinal wall. Taxonomic classification
Familie Strongylidae
