ABSTRACT

The incidence sexually transmitted diseases (STD) is a global public health problem, highly complicated by infections produced by the human immunodeficiency virus. Parasitic etiological agents of STD in Chile are limited to trichomonas vaginalis, sarcoptes scabiei and phthirus pubis. Only T. vaginalis has a trophozoite stage which can be diagnosed with a high degree of success in the laboratory. The present study reports on four culture methods which facilitate the primary isolation of this protozoan from clinical samples. The best results for primary isolation of T. vaginalis were obtained using modified diamond media. It was demonstrated that Kupferberg-Agar medium was the best for growth of T. vaginalis without re-inoculation. The optimal pH for the growth of T. vaginalis in the cultures was 6.5, and 10 percent horse serum gave the best yields in development and viability of T. vaginalis over time.


La incidencia de las enfermedades de transmisión sexual (ETS) se mantiene como problema de salud pública a nivel mundial, agravado por las infecciones por los virus de la inmunodeficiencia humana. Los agentes etiológicos parasitarios de ETS que existen en Chile se limitan a Trichomonas vaginalis, Sarcoptes scabiei y Phthirus pubis. T. vaginalis sólo posee estadio de trofozoito por lo que el diagnóstico de laboratorio es de alta exigencia. En este trabajo se evaluaron 4 medios de cultivo para facilitar el aislamiento primario de este protozoo a partir de muestras clínicas. Con el medio Diamond Modificado se obtuvo los mejores resultados para el aislamiento primario de T. vaginalis. Se comprobó que el medio Kupferberg-Agar fue el más adecuado para el crecimiento sin repique de T. vaginalis. Se determinó que el pH del medio de cultivo para el crecimiento óptimo de T. vaginalis, fue dr 6,5, y suero quino al 10 por ciento fue la concentración de mejor rendimiento para desarrollo y viabilidad en el tiempo de T. vaginalis.

ABSTRACT

In a field collection performed at Pan de Azúcar Island in Northern Chile, 95 specimens representing all instars of Mepraia spinolai were collected. The intestinal contents of 55 specimens were examined for Trypanosoma cruzi infection and were found to be negative. This is the first record of an insular habitat for M. spinolai, where the insects had fed mainly on seabirds (78), some on marine mammals (5), and some on reptiles (7).
