“…In Europe (Poland), four species of tabanids (Haematopota pluvialis, Tabanus bromius, Tabanus maculicornis, and Tabanus distinguendus) were found to be infected by trypanosomatids of the subgenus Megatrypanum, of which Trypanosoma theileri is a member, and the occurrence of a trypanosomatid in T. maculicornis and T. distinguendus was described in that study for the first time [32]. Chrysops laetus and Dichelacera tetradelta infected with T. theileri were recently described for northern Brazil [33]. Our data, are, to the best of our knowledge, the first molecular confirmation of the presence of T. evansi DNA in the feeding apparatus of D. alcicornis and D. januarii, and support previous findings.…”

Background Trypanosoma evansi infects a large number of wild and domestic animals and causes a spoliative disease known as surra. It is mechanically transmitted, mainly by biting flies of the genera Tabanus and Stomoxys. The detection of T. evansi DNA in the feeding apparatus of Dichelacera alcicornis and Dichelacera januarii from South America is reported, to the best of our knowledge, for the first time. Methods Tabanids were collected weekly from February 2018 to February 2019 from two sites. The feeding apparatus was removed and DNA extraction, polymerase chain reaction and sequencing were performed. Results A 205-base pair fragment of the variant surface protein RoTat 1.2 gene, confirmed by DNA sequencing, was amplified from the feeding apparatus of D. alcicornis and D. januarii. Conclusions This is, to the best of our knowledge, the first record of T. evansi DNA in South American tabanids. Graphical abstract

“…evansi com diagnóstico parasitológico e molecular em um animal doméstico no Estado de Rondônia. No Estado de Rondônia, o município de Monte Negro registrou uma ocorrência de infecção por T. evansi em cães, com 42,8% (3/7) dos animais testando positivo pela técnica de PCR (Bilheiro et al, 2019).…”

“…T. evansi também se adaptou ao parasitismo de hospedeiros silvestres neste continente, como capivaras (Hydrochoerus hydrochaeris) e quatis (Nasua nasua). Os relatos da ocorrência de T. evansi em cães de países da América do Sul são escassos, sendo recentemente detectada pela primeira vez no Paraguai (Recalde et al, 2021), Argentina , Uruguai (Greif et al, 2018) e Brasil (Jaimes-Dueñez et al, 2017;Aregawi et al, 2019;Bilheiro et al, 2019).…”

As tripanossomíases são um conjunto de doenças causadas por protozoários do gênero Trypanosoma. Entre elas, temos a surra ou mal-das-cadeiras, cujo agente etiológico é o Trypanosoma evansi, importante patógeno transmitido por moscas hematófagas, como tabanídeos e moscas do gênero Stomoxys. Além dos equinos, o T. evansi pode infectar e causar patologia importante em cães. Entretanto, há poucos relatos sobre epidemiologia, diagnóstico, patologia e terapêutica em cães no Brasil, a escassez de dados é ainda maior quando se trata de casos nos estados da Amazônia legal, como Rondônia. Este trabalho tem como objetivo relatar o primeiro caso de infecção natural por T. evansi em cão no município de Ariquemes, Rondônia, Brasil. Para tal, foram realizados exame físico do paciente e laboratoriais. Foi feito hemograma, análise parasitológica de esfregaços sanguíneos e PCR (polymerase chain reaction). A análise por microscopia de luz mostrou a presença de flagelados do gênero Trypanosoma com ausência do cinetoplasto, características das formas tripomastigotas sanguíneas de T. evansi encontradas na América do Sul. O diagnóstico para tripanossoma foi confirmado por PCR convencional. No exame físico, observou-se mucosas hiperêmicas, hipetermia, desidratação, taquicardia, dor a palpação abdominal, pelagem opaca e ptose bilateral. O hemograma evidenciou moderada anemia regenerativa, microcítica, normocrômica, além de leucopenia, linfopenia e trombocitopenia. O tratamento do paciente foi realizado, no entanto, devido à falha de execução pelo proprietário, o paciente veio à óbito. Este trabalho vem mostrar a necessidade de uma pesquisa epidemiológica criteriosa sobre T. evansi no estado de Rondônia, realizando a busca por possíveis vetores e hospedeiros vertebrados domésticos e selvagens com auxílio de ferramentas moleculares, como PCR e sequenciamento de DNA, sendo estas, indispensáveis para uma caracteriazação precisa da espécie do parasito e das cepas circulantes na região.

Review on trypanosomiasis and their prevalence in some country on the Red Sea

et al. 2023

Trypanosomiasis is a protozoan infection affecting both human and animals in almost all parts of the world. It can affect a very large range of domestic and wild hosts including camelids, equines, cattle, buffaloes, sheep, goats, pigs, dogs and other carnivores, deer, gazelles and elephants. This review paper was designed to address the effect of this economically important disease in countries on the Red Sea, especially in Egypt, Sudan, Somalia, and Saudi Arabia during the period 2010 to 2020. The prevalence of trypanosomiasis is different between these countries due to different types of diagnostic methods (Giemsa-stained blood smears, Hematocrit centrifugation, Serological test, and molecular analysis PCR) used and differential distribution of vector (Tse tse) flies. In current review, retrospective studies of published literature on distribution and prevalence of Trypanosoma evansi infection in the Red Sea Countries was conducted [Google Scholar and PubMed were used to retrieve the published literature from 2000-2020. A total of 77 published articles met the eligibility criteria and were reviewed. A total of 16 reports have been reported on the prevalence and distribution of Trypnosoma evansi infection in the Red Sea Countries have been from 2010-2020]. According to the published literature, we can say that trypanosomiasis in camels are more prevalent in Sudan than in other countries, followed by 17% and 51.78% in both clinical and non-clinical cases. Hence, the reliable diagnostic tests should be used for rapid treatment or control of the disease as if not treated appropriately in early-stage, can lead to death of the camels.
