Animal Trypanosomiasis in South America: Current Status, Partnership, and Information Technology

“…11 In the state of São Paulo, Brazil, the prevalence was 40.6 % and 30 % for buffaloes and cattle, respectively, as determined by culturing blood samples; however, all results were negative on microscopic examination. 12 Other members of this subgenus are: T. ingens, recently described in Suriname 13 ; T. mazamarum 1 ; T. minasense, which has been found in squirrel monkeys from the Brazilian Amazon 14 ; T. peba, described in armadillos from Brazil 15 ; T. freitasi in the opossum Didelphis marsupialis 16,17 ; T. rochasilvai, found parasitizing a small rodent ( Oryzomys laticeps ) from the state of São Paulo, Brazil 18 ; and T. melophagium, infecting ovines from the state of Minas Gerais. 19…”

Trypanosoma (Megatrypanum) saloboensen. sp. (Kinetoplastida: Trypanosomatidae) parasite ofMonodelphis emiliae(Marsupiala: Didelphidae) from Amazonian Brazil

“…T. (M.) freitasi Régo, Magalhães & Siqueira, 1957 was described in the opossum Didelphis azarae from the State of São Paulo, and re-encountered by Deane (1964) and Rocha e Silva et al, (1976) Deane, 1964 andRocha E Silva et al, 1976;Mello, 1977). The same authors recorded failure to detect division of these trypanosomes in the tissues of their hosts, and we found no such stages of T. (M.) Whether or not death was due to this trypanosome, however, remained uncertain.…”

“…Os achados de flebotomíneos infectados pelo tripanossoma de lagarto (T. varani) e por um tripanossoma filogeneticamente, próximo aos tripanossomas identificados em serpentes, sugerem que os flebotomíneos são possíveis vetores dos tripanossomas desse clado (MINTER-GOEDBLOED et al, 1993;VIOLA et al, 2008). Além disso, dentro do clado, é importante destacar que T. serpentis e T. cascavelli crescem em células de insetos da linhagem HI-5 (VIOLA et al, 2008;2009a) CAMARGO, 1976;VIOLA et al, 2009a;FERREIRA et al, 2017;LOPES et al, 2018;BRANDÃO et al, 2019;. Destas espécies, T. freitasi, T. gennarii e T. janseni foram descritas apenas em Didelphimorphia.…”

“…Estudos relacionados ao papel dos roedores como reservatórios de tripanossomatídeos documentaram diferentes espécies de Trypanosoma, sendo rochasilvai, T. cruzi, T. amileari, T. evansi, T. lewisi, T. musculi e Trypanosoma lainsoni (HERRER, 1942;ROCHA E SILVA;PATTOLI;CAMARGO, 1976;MELLO, 1979;FERRAZ FILHO, 1985;HERRERA;URDANETA-MORALES, 1997;NAIFF;BARRETT, 2013;PUMHOM et al, 2014;HONG et al, 2017;SANTOS et al, 2019).…”
