Nódulos linfáticos parietales en inspección rutinaria de caprinos

Abstract

El presente trabajo tuvo como objetivo identificar y describir los nodulos linfaticos de los caprinos, para establecer criterios sanitarios en el control de carne destinada al consumo. Se abordó la situación, forma y tamaño de los nódulos linfáticos (NL). Se utilizaron seis ejemplares adultos. Previa anestesia general, se realizó la eutanasia e inyección de tinta china a fin de que el drenaje linfá- tico fuera visible en la disección. Se observó que el NL cervical superficial o pre escapular, de forma elíptica, se situó en el borde craneal de la escápula. Los NL sub-ilíacos o pre-femorales, alargados, se situaron en craneal del músculo tensor de la fascia lata, equidistantes de la patela y el tubérculo coxal. El NL retro mamario, ovalado, se localizó en la región inguinal, rodeado de abundante cantidad de grasa. El NL poplíteo, de forma ovoide, se ubicó entre los músculos bíceps femoral y el contorno craneal del músculo semitendinoso. El NL prepectoral, costo cervical o falso ganglio del inspector, de forma alargada, se halló a lo largo de la superficie ventral de la tráquea. El NL ilíaco medio, con forma de coma, se ubicó cerca de la bifurcación de la aorta abdominal. El NL ilíaco lateral, redondeado, se situó en lateral del origen de los vasos ilíacos externos. A los NL isquiáticos, de forma ovoide, se los localizó en la incisura isquiática mayor, en craneal de la cresta isquiática. Los resultados difieren de los descriptos en esta especie por otros autores, en cuanto al número y tamaño de determinados linfocentros. El hallazgo permitirá adecuar los sistemas de vigilancia durante la inspección de rutina en la playa de faena y mejorar la calidad de los alimentos que llegan al consumidor

The present work is part of a project whose objective was to describe the lymphatic nodules of goats, for the application of sanitary criteria in the control of meat destined for consumption. This report describes the status, shape and size of lymph nodes (NL). Six adult specimens were used. After general anesthesia, euthanasia was performed. Subsequent to this, chinese ink is injected, so lymphatic drainage was visible in the dissection. It was observed that the superficial cervical or scapular NL, elliptic, is located at the cranial border of the scapula. The elongated NL sub-iliacus or pre femoral, were located in cranial of the tensor muscle of the fascia lata, equidistant of the patella and the coxal tuber. The NL retro mammary had oval shape and it was located in the inguinal region, surrounded by abundant fat. The popliteal NL had ovoid form, was located between the biceps femoris muscles and cranial contour of the semitendinosus muscle. The prepectoral NL, cervical cost or false lymph node of the inspector, elongated, was found along the ventral surface of the trachea. The middle iliac NL, had coma-shaped, it was located near the bifurcation of the abdominal aorta. The lateral iliac NL had a circular shaperounded, it was located lateral to the origin of the external iliac vessels. The sciatic nodes had ovoid shape, it were located in the major ischial incision, in the cranial of the ischial ridge. From the analysis of the results it was established that the external parietal lymphatic structures in routine inspection in goats, differ from those described in this species by other authors, in reference to the number and size in certain lymphocentres, this will allow to adapt the surveillance systems during the health inspection and will improve the quality of the food that reaches the consumer.
