Howlers (genus Alouatta) are widely captured with the use of anesthetic projectiles; however, no capture protocol involving the use of traps has been described to date. In the present study we describe the first efficient capture program for black and gold howlers (Alouatta caraya) using traps, which was implemented on the islands of the upper Paraná River… (More)

This study investigated the serological presence of SLEV in nonhuman primates and horses from southern Brazil. METHODS From June 2004 to December 2005, sera from 133 monkeys (Alouatta caraya, n=43; Sapajus nigritus, n=64;… (More)
We describe a congenital mature intracranial teratoma in a Pampas deer ( Ozotoceros bezoarticus ) in southern Brazil. We found an irregular, spongy, space-occupying mass in the brain. The tumor consisted of well-differentiated tissues that derived from all three germ layers.
Nonhuman primates are considered as the natural hosts of Hepatitis A virus (HAV), as well as other pathogens, and can serve as natural sentinels to investigate epizootics and endemic diseases that are of public health importance. During this study, blood samples were collected from 112 Neotropical primates (NTPs) (Sapajus nigritus and S. cay, n = 75;… (More)
