Primera descripción de tripanosoma vivax en Argentina

Abstract

El presente trabajo reporta por primera vez la presencia de Trypanosoma vivax en Argentina. Los hemo-parásitos fueron identificados en frotes finos de sangre de bovinos provenientes de un establecimiento ganadero en Formosa. En extendidos de gota fresca los parásitos mostraron característicos movimientos vibratorios que les permitía esquivar los glóbulos rojos y atravesar rápidamente el campo microscópico. Una cabra que fue infectada en forma experimental demostró la susceptibilidad de estos rumiantes a la cepa aislada, contrariamente de lo que ocurrió en ratones que mostraron resistencia. Información coincidente con la susceptibilidad de estos mamíferos al T. vivax. Los signos clínicos observados en los bovinos fueron: anemia, pérdida de peso, diarrea, emaciación e incoordinación de miembros. Se reporto la muerte de treinta y seis animales.

The present work reports the first occurrence of Trypanosoma vivax in Argentina. The hemoparasites were identified in thin blood smears of cows from a cattle-farm in Formosa. In weth blood films, the parasites showed characteristic vibratory movements, twisting its way between the red blood cells which allow crossing quickly the microscopic field. An experimentally infected goat showed the susceptibility of these ruminants to the isolated strain; contrarely mice were resistant to the infections, coincident with the susceptibility of these mammalians for T. vivax. The clinical signs observed in cattle were: anaemia, loss of weight, diarrhoea, emaciation, and difficulty in walking. The death of thirty six animals was reported
