Notas sobre o Trypanosoma cruzi e suas características bio-ecológicas, como agente de enfermidades transmitidas por alimentos

Abstract: A transmissão do Trypanosoma cruzi por via oral (VO) tem caráter habitual no ciclo enzoótico primitivo deste parasita, através da ingestão -por mamíferos suscetíveis -de vetores e reservatórios infectados. No caso do homem, esta transmissão ocorre de maneira esporádica e circunstancial, através de alimentos contaminados com o parasita, principalmente a partir de triatomíneos ou de suas dejeções 13 25 60 . Também, pode ocorrer através da ingestão de carne crua ou mal cozida de caça, ou de alimentos contaminados… Show more

“…Available experimental evidence suggests that oral transmission may occur from trypomastigote, epimastigotes, and probably amastigotes forms of T. cruzi and cell masses, originating from mammals or contaminated vectors, as well as, accidentally, through artificial cultures of the parasite (21) (23) (94) . Depending on the predominance of a large group or lineage of T. cruzi transmitted, as well as of the inoculum in question, there is a diversity in pathogenicity, histiotropism, morbidity, and mortality (21) .…”

“…The major clinical differences between the descriptions of past endemic areas and the Amazon region (in which oral transmission prevails) is the clinical presentation of high morbidity, highlighting the regional epidemiological characteristics regarding the occurrence of a more efficient mode of transmission than the vectorial route (76) (94) . Evaluation by non-specific complementary tests is generally similar to that previously seen.…”

“…El período de incubación de la enfermedad es de cinco días en promedio, y puede provocar una miocarditis aguda por transmisión parasitaria masiva, con una alta tasa de mortalidad y manifestaciones clínicas más graves en edades más tempranas (5,(8)(9)(10)(11)(12).…”
