Resumo
Background: : : : Trypanosoma evansi (T. evansi) is a protozoan which causes trypanosomosis in livestock in many countries of Southeast Asia, Africa and South America. Patterns of disease vary from acute epidemics with high case-fatality rates to subclinical and/or chronic disease in endemic animal populations. It is a problem of great economic importance due to the death of sick animals and high cost of treatment. This article aims to review the outbreaks of the infection by T. evansi in horses that occurred in southern Brazil. Review: These outbreaks were discussed in terms of epidemiology, clinical signs, laboratory tests, pathological findings, diagnosis and treatment by addressing the differences between the cases occurred in the state of Rio Grande do Sul and in other Brazilian states. The outbreaks due to T. evansi in livestock animals are endemic in warm-climate areas. At the Rio Grande do Sul state, most of the equine trypanosomosis occurs in the summer. This can be easily explained by the high number of bloodsucking insects, which are responsible for the mechanical transmission of the flagellate among the animals. Clinical signs such as progressive weight loss, lethargy, incoordination, instability, atrophy and paralysis of the hind limbs, difficulty in standing and walking, subcutaneous edema and abortion are often reported in T. evansi-infected equines. Anemia is
