In the German towns of Marburg, Frankfurt, and Belgrade in 1967, this single negativestranded RNA virus was initially discovered. The importation of infected grivet monkeys from Uganda is what caused this virus-related sickness. As a result of the early link between viruses and non-human primates, this virus is frequently referred to as vervet monkey sickness. This virus causes Marburg hemorrhagic fever in humans and non-human primates. Human endothelial cells serve as the primary vehicle for replication. According to a 2009 report, the virus was being stored in Egyptian fruit bats (Rousettus aegyptiacus). Body fluids, unprotected sex, broken or injured skin, and other bodily fluids are the main routes of transmission. After the incubation period, symptoms like chills, headaches, myalgia, and stomach pain start to show up. There is no specific medication for such an infection, only hydration therapy and adequate oxygenation are followed. The following diagnostic techniques can be used to confirm the diagnosis: (i) an antibody-capture enzyme linked immunosorbent assay (ELISA); ii) an antigen capture ELISA test; iii) a serum neutralization test; iv) an RT PCR assay; v) electron microscopy; or vi) virus isolation by cell culture. Because MARV is a risk group 4 infection, laboratory staff must take strict precautions (RG-4).

Currently, there is limited available information on the epidemiology of parasitic infections in captive non-human primates (NHPs) and their zoonotic potential. However, numerous cases of helminth infections in NHPs have been documented in several zoos around the world, with one of the most prevalent being those of the genus The main objective of this study is to investigate the occurrence of infection by spp. in primates from zoological gardens in Spain and to ascertain, at the species level, the specific species harbored by these hosts by using mitochondrial and ribosomal markers.

However, its translational potential is hindered by adverse effects stemming from the invasive implantation of optical fibers into the brain. In this study, we have developed a non-invasive optogenetics approach, utilizing focused ultrasound-triggered mechanoluminescent nanotransducers to enable remote photon delivery deep in the brain for genetically targeted neuromodulation.

Major depressive disorder (depression) is a highly heterogenous human mental disorder that may have equivalents in non-human animals. Research into non-human depression teaches us about human depression and can contribute to enhance welfare of non-human animals. Here, we narratively review how signs of depression in non-human primates (NHPs) can be observed based on symptoms of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).

Argali stands as the largest species among wild sheep in Central and East Asia, with a concerning rate of decline estimated at 30%. The intraspecific taxonomy of argali remains contentious due to limited genomic data and unclear geographic separation. In this study, we constructed a chromosome-level genome assembly and annotation for the Tibetan argali (O.

Background: Neuronal activity is modulated by behavior and cognitive processes. The combination of several neurotransmitter systems, acting directly or indirectly on specific populations of neurons, underlie such modulations. Most studies with non-human primates (NHPs) fail to capture this complexity, partly due to the lack of adequate methods for reliably and simultaneously measuring a broad spectrum of neurotransmitters while the animal engages in behavioral tasks.
