Abdominal Ultrasound in Saguinus ursulus
Neotropical primates, Ultrasound, Wild animals, Tamarins.
The classification of Saguinos as a new book evidences a lack of data in the literature on the anatomical and physiological specificities of the species, as well as their vulnerability situation caused by the degradation of their native area. The aim of this study was to determine the ultrasonographic parameters of normal pelvic-abdominal structures and organs of the species. Nine first targets were made at the National Primate Center (CENP), with the help of three female reproductive organs that were evaluated every 48 hours for 60 days. to follow the follicular dynamics. Topography and morphology were included along with the biometrics of the abdominal and pelvic organs. The bladder is seated dorsi-ventrally with hyperechoic walls well delimited and anechoic content; light kidneys in retroperitoneal region, more cranial and oval right and triangular left kidney; left cranial spleen, fusiform and hypoechoic; stomach caudal to the liver and medial to the spleen, with five decreases; cranial liver to the stomach and caudal to the diaphragm within the costal gradient border, sharp edges, coarse ecotexture, from hypoechoic to isoechoic in relation to the cortex of the right kidney; gallbladder positioned in the xiphoid region, rounded, may be bilobated or not, well defined hyperechoic walls and anechoic content; medial duodenum located on the right kidney, only three of the five layers (face of the mucosa, mucosa and submucosa) were visualized; The region with pelvic, pyriform-shaped and three well-defined chains (myometrium, endometrium and lumen); ovaries to the uterus, ellipsoids, homogeneous to heterogeneous ecotexture, hypoechoic with or without follicles, with the following formatted format, well delimited walls and anechoic content; testicles in the scrotal search, finely coarse ecotexture and increased echogenicity, the mediastinum line was visualized in an animal. The species S. ursulus has demonstrated an ultrasound anatomy similar to other neotropical primates, but a description of pelvic-abdominal structures in the species is unpublished and may support post-conservation studies and veterinary medical care.
