Estudo comparativo de detecção de metapneumovírus humano pelos métodos de PCR e imunofluorescência direta

Abstract: Introdução: O metapneumovírus humano (MPVh) causa infecções respiratórias em crianças, adultos e idosos imunodeprimidos. O diagnóstico é realizado por imunofluorescência (IF) ou biologia molecular. Objetivo: Detectar o MPVh em amostras clínicas pelos métodos de reação em cadeia da polimerase (PCR) e imunofluorescência direta (IFD). Resultados: Das 202 amostras, a positividade foi de 2% e 4% para IFD e RT-PCR, respectivamente. Sensibilidade e especificidade da IFD foram de 50% e 100%, respectivamente, considera… Show more

“…Analytical specifi city was very high (99%), considering the global analysis of all the samples or even in the separate evaluation of the two studied population groups (children and adults). Similar results have been reported previously (9) (10) (11) . In contrast, analytical sensitivity was low: 38% for all patient samples; 39.5%, for children; and 25%, for adults.…”
