Climatic factors related to Chagas disease transmission

Climatic factors related to Chagas disease transmission.

Oral transmission of Chagas disease.

Chagas disease is now an active disease in the urban centers of countries of nonendemicity and endemicity because of congenital and blood and/or organ transplantation transmissions and the reactivation of the chronic disease in smaller scale than vectorial transmission, reported as controlled in countries of endemicity. Oral transmission of Chagas disease has emerged in unpredictable situations...

Rheumatoid factors and Chagas' disease.

godial (1), which constitutes its chemical defense and is stored in the mantle. Thus the ability of a nudibranch to elaborate its chemical defense has been demonstrated. Dendrodoris limbata also synthesizes the mixture of sesquiterpenoid esters (2) found in the digestive glands. We believe that these esters should be regarded as products of further metabolism of polygodial as a result of a deto...

Pasteurization of human milk to prevent transmission of Chagas disease.

Although admittedly transmission of Trypanosoma cruzi infection through breastfeeding is a rare event, it involves serious risks. To test the effectiveness of pasteurization in preventing this mode of infection, three sets of samples of human milk were tested: a - contaminated with T. cruzi and pasteurized; b - contaminated with T. cruzi and non-pasteurized; c - non-contaminated and pasteurized...

Elimination of Chagas disease transmission: perspectives.

One hundred years after its discovery by Carlos Chagas, American trypanosomiasis, or Chagas disease, remains an epidemiologic challenge. Neither a vaccine nor an ideal specific treatment is available for most chronic cases. Therefore, the current strategy for countering Chagas disease consists of preventive actions against the vector and transfusion-transmitted disease. Here, the present challe...
