Trypanosoma evansi infection in mainland Spain.

Abstract: An outbreak of Trypanosoma evansi infection that occurred in mainland Spain is described. The outbreak occurred on an equine and camel farm to which dromedary camels from an infected area of the Canary Islands had recently been introduced. One of these camels developed clinical signs and T. evansi was discovered in a blood smear examination. The herd was evaluated in order to determine the extent of the disease. The results showed that 76% of the camels, 35% of the donkeys and 2% of the horses were affected. The animals were isolated and treated using Cymelarsan((R)) (0.5mg/kg). After treatment, three blood analysis using parasitological methods revealed negative results. This is the first T. evansi outbreak to have occurred in mainland Spain and the second in mainland Europe, both occurring after the introduction of dromedary camels from the Canary Islands.

The research paper discusses an outbreak of Trypanosoma evansi infection that affected animals on a farm in mainland Spain, notably after the introduction of dromedary camels from the Canary Islands.

Context and Setting

  • The focus of the study revolves around an outbreak of Trypanosoma evansi infection. This parasitic disease, mostly associated with camels, was observed in mainland Spain, specifically on an equine and camel farm.
  • The incident caught the researchers’ attention as it’s the first of its kind in mainland Spain and only the second in mainland Europe.
  • Incidentally, the outbreak occurred shortly after dromedary camels from an infected area of the Canary Islands were brought to the farm, suggesting a likely link between the introduction of these animals and the outbreak.

Outbreak Investigation and Findings

  • Upon the development of clinical signs in one of the newly introduced camels, the researchers performed a blood smear examination which confirmed the presence of T. evansi.
  • Subsequently, an evaluation of the entire herd was conducted to determine the extent of the disease. Examination results showed that 76% of the camels, 35% of the donkeys, and 2% of the horses at the farm were affected by the infection.

Treatment and Post-Treatment Outcomes

  • The infected animals were isolated and treated with Cymelarsan® (0.5mg/kg), a therapeutic agent known for combating T. evansi infection.
  • Following the treatment, the researchers carried out three separate blood analyses using parasitological methods – all of which revealed negative results, indicating that the treatment was successful in combating the parasite infection in the treated animals.

Implications and Comments

  • The research indicates that the introduction of animals from areas known to carry certain diseases could potentially lead to an outbreak in regions previously unaffected by such infections. This is especially critical for diseases like T. evansi infection, which aren’t region-specific and can affect a variety of animal types.
  • This study’s findings highlight the importance of thoroughly screening animals for potential diseases before transporting them from one location to another, especially across continents.
