1. Estilos de cuidado materno em primatas: considerações a partir de uma espécie do Novo Mundo
Resumo Quando buscamos entender o comportamento humano, comparações com primatas não humanos são especialmente relevantes para identificar homoplasias (características semelhantes que evoluem independentemente em diferentes espécies). Neste artigo, apresentamos um estudo longitudinal de dois anos sobre o comportamento materno de macacos-prego (Sapajus

2. HEART MEASUREMENTS OF NON-HUMAN PRIMATES BY RADIOGRAPHIC TECHNIQUES
Resumo O uso da radiologia torácica surge como forma de diagnóstico para inúmeras anormalidades, inclusive cardíacas, as quais podem ser avaliadas por métodos VHS (vertebral heart size), realizado a partir da mensuração do comprimento e largura do coração e CTR (cardiothoracic ratio), o qual compara a largura do coração, pelo diâmetro torácico.

3. Bone marrow mononuclear cells versus mesenchymal stem cells from adipose tissue on bone healing in an Old World primate: can this be extrapolated to humans?
RESUMO Na medicina veterinária, a terapia celular ainda é inexplorada e há muitas perguntas não respondidas, o que leva os pesquisadores a uma tendência a estender a terapia para os seres humanos, na tentativa de tratar certas lesões. Investigar esse assunto em primatas não humanos revela-se uma oportunidade sem precedentes para compreender melhor a d

4. West Nile virus infections are here! Are we prepared to face another flavivirus epidemic?
Abstract Emerging arthropod-borne viruses (arboviruses), such as chikungunya and Zika viruses, are a major threat to public health in countries like Brazil where biodiversity is high and medical care is sometimes precarious. West Nile fever is a disease caused by the West Nile Virus (WNV), an RNA virus belonging to the Flaviviridae family. It is transmitted

5. Neuroscience: unveiling the brain of Saimiri collinsi (Squirrel Monkey)
Abstract Behavioral intelligence among non-human primates is a somewhat puzzling area to study, since it is closely linked to the morphology of the central nervous system. However, this morphology is still unknown to science in the case of Saimiri collinsi. As a means of assisting future studies on the social behavior of this species, we analyzed the brains

6. Yellow fever outbreak in Brazil: the puzzle of rapid viral spread and challenges for immunisation
We discuss the complex eco-social factors involved in the puzzle of the unexpected rapid viral spread in the ongoing Brazilian yellow fever (YF) outbreak, which has increased the reurbanisation risk of a disease without urban cases in Brazil since 1942. Indeed, this rapid spatial viral dissemination to the Southeast and South regions, now circulating in the

7. Genome analysis of yellow fever virus of the ongoing outbreak in Brazil reveals polymorphisms
The current yellow fever outbreak in Brazil is the most severe one in the country in recent times. It has rapidly spread to areas where YF virus (YFV) activity has not been observed for more than 70 years and vaccine coverage is almost null. Here, we sequenced the whole YFV genome of two naturally infected howler-monkeys (Alouatta clamitans) obtained from th

8. Detection of Plasmodium in faeces of the New World primate Alouatta clamitans
Abstract Plasmodium falciparum and Plasmodium vivax have evolved with host switches between non-human primates (NHPs) and humans. Studies on the infection dynamics of Plasmodium species in NHPs will improve our understanding of the evolution of these parasites; however, such studies are hampered by the difficulty of handling animals in the field. The aim of

9. Detection of antibodies to Oropouche virus in non-human primates in Goiânia City, Goiás
Abstract: INTRODUCTION Arboviruses are associated with human disease, and non-human primates (NHPs) are important primary hosts. This study shows the detection of antibodies to Oropouche virus (OROV) in NHPs either living in urban parks or acclimatized at the Wild Animal Screening Center, Goiânia city. METHODS: Fifty blood samples were analyzed by hemagg

10. SEROLOGICAL DETECTION OF HEPATITIS A VIRUS IN FREE-RANGING NEOTROPICAL PRIMATES (Sapajus spp., Alouatta caraya) FROM THE PARANÁ RIVER BASIN, BRAZIL
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; Alouatt

11. Frequency of histopathological changes in Howler monkeys ( Alouatta sp.) naturally infected with yellow fever virus in Brazil
Abstract: INTRODUCTION: Due to the importance that Howler monkeys have on the yellow fever (YF) epidemiological sylvatic cycle in Brazil, more accurate morphological diagnostic criteria needs to be established, especially considering the differences that may exist between the genera of Brazilian non-human primates (NHPs) involved in yellow fever virus (YFV)

12. Evaluation of arboviruses of public health interest in free-living non-human primates (Alouatta spp., Callithrix spp., Sapajus spp.) in Brazil
INTRODUCTION: The aim of the present study was to evaluate the presence of arboviruses from the Flavivirus genus in asymptomatic free-living non-human primates (NHPs) living in close contact with humans and vectors in the States of Paraná and Mato Grosso do Sul, Brazil. METHODS: NHP sera samples (total n = 80, Alouatta spp. n = 07, Callithrix spp. n = 29 a
