These parasites are widespread worldwide and particularly affect cats, but can also infest other animals. The parasite's life cycle takes place entirely in the stomach of the host, which distinguishes it from many other parasitic worms that often require an intermediate host.  <\/p>\n\n<p>Ollulanus tricuspis lives in the stomach and causes damage to the gastric mucosa. These parasites are viviparous, meaning that the females produce live larvae that can develop directly into adult worms in the stomach. This allows rapid reproduction of the parasites without the need for an external development stage.  <\/p>\n\n<p>Infection usually occurs by swallowing vomit containing the larvae or adult worms. Since cats often eat their own vomit or that of other cats, the parasite can easily spread within a cat population. <\/p>","auswahl_symptome_rot":[35109,35245,35045],"auswahl_symptome_blau":[35277,34548],"auswahl_symptome_grun":[35363,35166,34948],"erganzungen_zu_symptomen":"<p>The symptoms of stomach worm infection in cats can vary depending on the severity of the infestation. Common symptoms include repeated Vomiting, which often occurs after eating. In many cases, the Vomiting can become chronic and lead to Weight loss.  <\/p>\n\n<p>Other symptoms may include loss of appetite, lethargy, and dehydration. In severe cases, inflammation of the gastric mucosa can occur, which is known as gastritis. This can lead to pain and further discomfort for the affected cat.  <\/p>\n\n<p>Since the symptoms are non-specific, they can easily be confused with other diseases of the gastrointestinal tract. An accurate diagnosis is therefore crucial for the correct treatment. <\/p>","diagnose":"<p>The diagnosis of a stomach worm infection requires a thorough examination by a veterinarian. Due to the small size of the parasite, detection is often difficult. In many cases, a diagnosis is made by microscopic detection of the parasites in the Vomiting, as the worms are often visible there.  <\/p>\n\n<p>Another diagnostic procedure may be an endoscopic examination of the stomach, in which a camera is used to directly inspect the gastric mucosa and take samples for further examination. In some cases, blood tests may be performed to assess the cat's general health. <\/p>","behandlung":"<p>Treatment of stomach worm infection in cats typically involves using antiparasitics that are specifically effective against roundworms. Medications such as fenbendazole or levamisole are often used to eliminate the parasites. <\/p>\n\n<p>In addition to drug treatment, it may be necessary to adjust the cat's diet to support the healing of the gastric mucosa. In some cases, a special diet may be recommended that is easily digestible and gentle on the stomach. <\/p>\n\n<p>It is important to carry out the treatment consistently and have the cat regularly monitored by a veterinarian to ensure that the infection is successfully controlled.<\/p>","prognose":"<p>The prognosis for cats with a stomach worm infection is generally good if the disease is detected and treated early. Most cats recover completely from the infection, especially if treated in time. <\/p>\n\n<p>In cases where the infection is not treated in time or the cat is already weakened, the prognosis may be worse. Chronic infections can lead to persistent stomach problems and a deterioration in the cat's general condition. <\/p>\n\n<p>Regular monitoring and aftercare by a veterinarian is important to prevent relapses and ensure the cat's long-term health.<\/p>","zusammenfassung":"<p>Stomach worm infection in cats is caused by the microscopic roundworm Ollulanus tricuspis, which is widespread worldwide.

Gastric biopsy demonstrates the parasites histologically."},{"frage":"5. How is it treated?","antwort":"Fenbendazole or ivermectin are used, though efficacy against this parasite is limited. Treatment must be repeated."},{"frage":"6. Is Ollulanus tricuspis host-specific?","antwort":"Ollulanus tricuspis has a broad host range. Cats are the primary hosts, but dogs, foxes, tigers and other felids can also be infected."},{"frage":"7. Does ollulanosis always cause symptoms?","antwort":"Some cats carry the parasite subclinically without symptoms and act as reservoir hosts. Others develop severe chronic gastritis."},{"frage":"8. How common is ollulanosis in cats?","antwort":"Ollulanosis is more prevalent in outdoor cats in certain regions but is frequently undiagnosed because of the demanding diagnostic technique."},{"frage":"9.
