[Cyathostominosis: a form of severe strongylidosis (author’s transl)].

The study discusses Cyathostominosis, a type of strongyle infection seen in young horses and ponies, characterized by the presence of large amounts of Cyathostominae larvae in their faeces, unaffected by anthelmintics, and leading to a high fatality rate due to complications of verminous enteritis.

Description of Cyathostominosis

This research describes Cyathostominosis, an infection caused by strongyle worms, otherwise known as roundworms. The study noted that this condition particularly affects young horses and ponies, and the symptoms were most prominently seen from November through May.

• The main sign of this infection is the excretion of large amounts of Cyathostominae larvae, found in the fourth or early fifth stage of development, in the animals’ faeces. Often, the faeces are watery, indicating a form of diarrhoea, which is a common symptom of parasitic infections.

Anthelmintics Ineffectiveness

Anthelmintics, drugs that are used to eliminate parasitic worms, were found to be ineffective in this instance. Despite treatment:

• The researchers noticed that the horses still excreted large numbers of Cyathostominae larvae in their faeces. This suggests resistance of these worms to conventional treatment options.

Fatality Rate

A significant finding from this research paper is the high fatality rate associated with Cyathostominosis. The condition led to:

• A large number of deaths among young horses and ponies due to complications of verminous enteritis. This is an inflammation of the intestines caused by parasitic worms.
