ABSTRACT

Disímiles son los métodos serológicos empleados para la determinación de anticuerpos IgG anti-Toxoplasma gondii en diferentes muestras de estudio. El objetivo es realizar una comparación entre el método de Inmunofluorescencia Indirecta y el Toxoplasma látex porBrunella para demostrar cual es el método más sensible y específico para determinar seroprevalencia de anticuerpos IgG anti- Toxoplasma gondii en neonatos asistidos en la Sala de Neonatología del Hospital Valdimir Ilich Lenin. Se analizaron 30 muestras de sueros de niños recién nacidos asistidos en este Servicio por las dos pruebas, de ellas se conformaron dos grupos de trabajo. Los resultados demostraron que la prueba de Inmunofluorescencia Indirecta es la más útil para este diagnóstico, coincidiendo con investigaciones similares realizadas


Dissimilar are the methods used to determine the seroprevalence of IgG antibodies against to Toxoplasma gondii in different samples. In this research were compared to Indirect Immunofluorescence and Toxoplasma Latex by Brunelli to prove which of them is the most sensitive and specific to determine seroprevalence of IgG anti-Toxoplasma gondii in newborn in Neonatology Service at Lenin Hospital of Holguin Province, Cuba is the main objective. Thirty samples were analyzed of newborns treated in Neonatology Service using these methods, besides two working groups were formed. The sensitivity and specificity of Indirect Immunofluorescence were 100 % and 95 % respectively and Toxoplasma latex reported a sensitivity of 96.1 % and a specificity of 89.6 %. These results showed that the Indirect Immunofluorescence Technique is the most useful for these diagnostic and this result are similar with others investigations
