RESUMEN
Se determinó la prevalencia de anticuerpos a Mycoplasma meleagridis en 20 lotes de pavos reproductores del departamento de Lima durante el año 2007. Se tomaron 400 muestras de sangre de pavos machos y hembras, entre 8 y 57 semanas de edad, en los distritos de Asia y Chilca. Las muestras se analizaron mediante el ensayo de inmunoabsorción ligado a la enzima (ELISA) a fin de determinar la presencia de anticuerpos contra M. meleagridis. Se encontraron tres muestras positivas (una por lote), resultando una prevalencia de 0.75 ± 0.04%. La seropositividad por lote afectado fue de 5%, sin que se mostrasen signos clínicos compatibles con la enfermedad. Se concluye que los 20 lotes examinados no fueron expuestos al microorganismo y que estos resultados se deben a reacciones falsas positivas.
A field study was conducted to determine the prevalence of antibodies against Mycoplasma meleagridis in 20 turkey breeder flocks located in the Lima region during 2007. A total of 400 blood samples were taken from male and female birds of 8 to 57 weeks old, from Asia and Chilca districts. The indirect enzyme linked immunosorbent assay (ELISA) was used to measure serum antibodies against M. meleagridis. Three positive samples were found (one per flock) representing a prevalence of 0.75 ± 0.04%. The seropositive reactivity per affected flock was 5%, and without showing clinical signs compatible to those observed in the disease. According to these findings, it is concluded that the 20 flocks were not exposed to M. meleagridis and that the positive results may be due to false positive seroreactions.
