RESUMO
La enfermedad de Chagas constituye una infección severa de alta prevalencia en Argentina y otros países latinoamericanos. La administración de drogas reumáticas inmunosupresoras en estos pacientes, muchas veces es necesaria, pero no se conoce aún la implicancia que esto puede tener en la reactivación de la enfermedad de Chagas. En esta puesta al día se revisan criterios generales de diagnóstico en este grupo de pacientes y las recomendaciones realizadas al respecto
Chagas disease constitutes a severe infection of high prevalence in Argentina and other Latin American countries. The administration of immunosuppressive rheumatic drugs in these patients is often necessary but the implication that this may have on the reactivation of Chagas disease is not yet known. In this update, general diagnostic criteria in this group of patients, and available evidence and recommendations made in this context are reviewed

Candida guilliermondii developed a pink-purplish colony on CHROMagar Candida. In the micromorphology in milk-tween 80 1% agar at 28 degrees C after 48 h of incubation C. guilliermondii showed small (3-5 microm), spherical yeasts without pseudohyphaes. This Candida species presented a characteristic cluster of blastospores with pseudohyphaes radiating from the centre at 96 h. The trehalose-sucrose assimilation assay was applied to the C. guilliermondii isolates which proved negative for trehalose and positive for sucrose. These results allowed for the presumptive identification of C. guilliermondii. The results were concordant in 100% of the isolates with the identification of the C. guilliermondii species by the ID 32C and Vitek YBC methods. Such automated methods offered Candida famata as a second option, with a reliability percentage of 10%. Micromorphological studies increase yeast identification reliability, especially among species presenting similar biochemical profiles.
