Animal trypanosomiasis in South America. Current status, partnership, and information technology.

Abstract: Animal trypanosome species of economical importance in South America include T. vivax and T. evansi. Both species are described in Brazil, Bolivia, Colombia, French Guyana, Peru, Suriname, and Venezuela. In Argentina and Guyana, only T. evansi and T. vivax are found, respectively. Our studies on T. vivax indicated that the parasite was spreading around 1.3 km per day in Bolivia. We found severe leukopenia in bovines from Pantanal (Brazil) and the Department of Santa Cruz (Bolivia). Because it can cause immunosuppression, the importance of trypanosomiasis control in ensuring success of vaccination campaigns against foot and mouth disease (FMD) in the Pantanal and Bolivia should be considered. The use of one needle for several animals during FMD campaigns in Brazil and Bolivia could also contribute to the spread of T. vivax. The anticipated losses due to T. vivax could exceed $160 million, assuming there are 11 million head of cattle in the Brazilian Pantanal and Bolivian lowlands. International collaboration among research institutes is needed to deal with these diseases and parasites. Previous efforts using information technologies resulted in the creation of two discussion lists (Tryplink and Trypan), the edition of the on-line version of Trypnews and Internet conferences.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

This research article examines the current issue of animal trypanosomiasis in South America, specifically T. vivax and T. evansi parasites that affect the cattle industry, and the need for international collaboration and efficient use of information technology to control this parasitic infection.

Animal Trypanosomiasis in South America

  • The research focuses on the economic impact of animal trypanosome species, particularly T. vivax and T. evansi on the livestock industry in South America.
  • Both species are identified in various South American countries including Brazil, Bolivia, Colombia, French Guyana, Peru, Suriname, and Venezuela. However, only T. evansi is found in Argentina and only T. vivax is present in Guyana.

Impact of Trypanosomiasis on Livestock Health

  • The study highlights severe leukopenia in bovines from Pantanal (Brazil) and the Department of Santa Cruz (Bolivia) as evidence of the disease’s spread.
  • Due to its immunosuppressive effects, trypanosomiasis poses a significant barrier to successful vaccination campaigns against diseases such as foot and mouth disease (FMD).
  • The needle-sharing practice during FMD vaccination campaigns in Brazil and Bolivia could also contribute to the spread of T. vivax.
  • The estimated economic losses linked to T. vivax infections could reach over $160 million, considering there are about 11 million head of cattle in the Brazilian Pantanal and Bolivian lowlands.

Need for International Collaboration and Information Technology

  • The author asserts that international collaboration among research institutes is crucial to addressing and managing these diseases and parasites.
  • Past attempts to utilise information technology have led to the creation of online discussion platforms like Tryplink and Trypan, the online publication of Trypnews, and the hosting of internet-based conferences.
  • These online resources facilitate global communication and collaboration in the ongoing fight against trypanosomiasis and other parasitic diseases affecting the global livestock industry.
