Abstract

Cutaneous basophil hypersensitivity (CBH) was evaluated in two experiments using a neck skin (dewlap) test site on adult domestic turkey hens. The CBH response elicited by an intradermal injection of phytohemagglutinin-P (PHA-P) was evaluated by determining dewlap thickness at the injection site immediately before injection and 24, 48, or 72 hr after injection. It was determined that a dose level between 30 and 90 μg PHA-P induced a suitable dermal swelling. Laying hens had a dermal response that was about 69% of the response in nonlaying hens. The results indicated that the dewlap test is a rapid, simple, and effective means of assessing a cell-mediated immune response in adult turkey hens. /// La hipersensibilidad cutánea basofílica fue evaluada en dos experimentos utilizando un examen cutáneo en el cuello en pavas domésticas adultas. La respuesta de la hipersensibilidad cutánea basofílica se obtuvo mediante la inyección intradérmica de fitohemaglutinina-P y fue evaluada determinando el grosor de la piel en el sitio de la inyección inmediatamente antes de la inyección y a las 24, 48 ó 72 horas postinyección. Se determinó que una dosis entre 30 y 90 μg de fitohemaglutinina-P inducía una inflamación cutánea adecuada. Las ponedoras tuvieron una respuesta cutánea cercana al 69% de la respuesta de las no ponedoras. Los resultados indicaron que el examen cutáneo del cuello es un método rápido, sencillo y eficaz para evaluar la respuesta inmune celular en pavas adultas.
