Manejo experimental de saguis invasores: captura, esterilização, pós-operatório e soltura

Biodiversidade Brasileira
O sagui-da-serra-escuro (Callithrix aurita) é um primata endêmico da Mata Atlântica do sudeste do Brasil considerado “em perigo” de extinção. Uma das principais ameaças à espécie é a expansão de congêneres invasores, que impactam a espécie nativa em ...

Yellow fever epizootics in non-human primates, Southeast and Northeast Brazil (2017 and 2018)

Parasites & Vectors, 2020
Background Yellow fever (YF) is a severe, infectious, but non-communicable arboviral hemorrhagic disease. In the last decades, yellow fever virus (YFV) infections have been prevalent in endemic areas in Brazil, affecting human and non-human primate (NHP)

Vector-borne transmission of Trypanosoma cruzi among captive Neotropical primates in a Brazilian zoo [PDF]

, 2016
Background: Neotropical primates are important sylvatic hosts of Trypanosoma cruzi, the etiological agent of Chagas disease. Infection is often subclinical, but severe disease has been described in both free-ranging and captive primates.

Vocalizations Reveal Species Differences in Endangered Lion Tamarins (Primates, Callitrichidae)

American Journal of Primatology, Volume 88, Issue 1, January 2026.
Spectral parameters of vocalizations distinguish lion tamarin species. Peak frequency, center frequency, and frequency at 5% and 95% were the most informative measures for separating species, with the trill being the vocalization that showed the most differences, and Leontopithecus caissara being the most distinct species of all.

Behavioral Contagion in Wild Ecuadorian White‐Fronted Capuchins (Cebus aequatorialis)

American Journal of Primatology, Volume 88, Issue 1, January 2026.
White‐fronted capuchins exhibit scratching contagion, but neither the characteristics of the trigger, or of the partner's (sex, age class, or centrality), or of the dyad (combination of sex, combination of age class, or social bond) seem to modulate the likelihood of contagion.

Multiple Mitochondrial Dysfunction Syndrome Caused by IBA57 Gene Mutation: A Case Report and Literature Review

Molecular Genetics &Genomic Medicine, Volume 14, Issue 1, January 2026.
We report a novel IBA57 variant in a pediatric case, with pathogenicity confirmed through familial segregation analysis, Sanger sequencing, 3D protein modeling, and evolutionary conservation studies. Mitochondrial complex activity assays demonstrated functional impairment. A comprehensive review of literature further elucidates the genotypic‐phenotypic

The current status of the New World monkey phylogeny

Anais da Academia Brasileira de Ciências, 2000
Four DNA datasets were combined in tandem (6700 bp) and Maximum parsimony and Neighbor-Joining analyses were performed. The results suggest three groups emerging almost at the same time: Atelidae, Pitheciidae and Cebidae.

Chromosomal distribution of interstitial telomeric sequences in nine neotropical primates (Platyrrhini): possible implications in evolution and phylogeny [PDF]

, 2016
To localize interstitial telomeric sequences (ITSs) and to test whether their pattern of distribution could be linked to chromosomal evolution, we hybridized telomeric sequence probes (peptide nucleic acid, PNA) on metaphases of New World monkeys ...
