ABSTRACT
The determination of health status in spider monkeys (Ateles geoffroyi) that are held in managed care requires periodic evaluation. The present study obtained baseline data on hematologic values, body weight, and length in A. geoffroyi. A total of 118 individuals from three housing centers were included in the study and grouped into two categories by age (92 adults, 26 juveniles) and sex (46 males, 72 females). Body weight, red blood cell (RBC) counts, and hemoglobin counts were significantly higher in adult males than in adult females. No differences in length were found between sex and age groups. The present findings indicate that hematologic values by age and sex in A. geoffroyi are similar to those reported in other spider monkey populations in both managed care and the wild. These results will be useful as a reference for young individuals and adults in future studies of the health of this species.

Lipopolysaccharide (LPS) is a potent immunogen when administered locally and/or systemically. The peripheral immunization with LPS could contribute to the progression of neurological diseases because a strong link between neuroinflammation and dopaminergic degeneration has been found. The switch between the survival and neuronal death in substantia nigra could be related to M1 (neurotoxic) and M2 (neuroprotective) microglia phenotypes. In this review, we present the current findings about microglia roles, biomarkers, and natural or synthetic immune modulators determined in the LPS-based murine model.
