En el presente estudio se comparó la técnica de inmunoperoxidasa para la detección de citomegalovirus (IPCMV) utilizando anticuerpos monoclonales que reconocen proteínas precoces virales con el método convencional de aislamiento viral en fibroblastos humanos. Un total de 150 muestras de orina fueron examinadas encontrando una sensibilidad de un 89.8% y una especificidad de 91.3% de la técnica de IPCMV comparada con el aislamiento viral. Una de las ventajas que presentó la IPCMV fue la rapidez con que fueron obtenidos los resultados (48 horas) mientras que el aislamiento viral fue como promedio 14 días.

Unitermos: Citomegalovirus; Inmunoperoxidasa; Aislamiento viral.


An Immunoperoxidase assay was applied to detect early antigens of Cytomegalovirus (CMV) in 150 urine samples from immunocompromised patients, using the commercial available monoclonal antibody against CMV El3. The detection of early antigen by IP (IPCMV) is compared to the conventional cell culture isolation regarding specificity and sensitivity in order to evaluate is usefulness in the diagnostic of CMV infections. The IPCMV showed a sensitivity of 89.8% and a specificity of 91.3% when compared to the isolation method. The great advantage of the IPCMV is based on the shorter time results are achieved, since 48-72 Hs can be enough to provide evidence of CMV infection, while in the isolation technique cytopatho-genic effect was present around 14 days after sample inoculation.
