El 4 de junio de 2021, partió a la eternidad nuestro amigo, colega y maestro, el Dr. Manuel Edmundo Tantaleán Vidaurre, docente universitario, un distinguido parasitólogo, en particular en la helmintología. Este trabajo rinde homenaje al maestro e investigador que con su trayectoria, entre aulas y laboratorios, fue sembrando la curiosidad y el conocimiento científico que inspiró a muchos de sus alumnos y estudiantes.

The aim of this study was to compare the techniques of indirect immunofluorescence (IFAT) and Enzimo inmunoensayo (ELISA) techniques for the diagnosis of Neospora caninum Dubey, Carpenter, Speer, Topper & Uggla, 1988 in alpacas from the highlands of Peru. Sensitivity, specificity, positive predictive value, negative predictive value and concordance of IFAT were evaluated using a commercial competitive ELISA kit (cELISA - VMRD) as a reference. 1540 sera samples were collected from alpacas naturally exposed to N. caninum. The results showed good sensitivity (92.95%), high specificity (99.75%), positive predictive value of 92.90% and a negative predictive value of 99.04%. The concordance between both diagnostic techniques (IFAT and ELISA) turned out to be almost perfect (k = 0.98). It is concluded that the IFAT test has a high efficiency for the diagnosis of N. caninum in alpacas.
