AI Article Synopsis

  • The study focuses on how flies that associate with nonhuman primates are moving between natural habitats and more populated human areas around Kibale National Park in Uganda.
  • Researchers used a mark-recapture method to track the movement of these flies, marking a large number in nine different primate groups and later recapturing some in human-inhabited areas.
  • Genetic analysis showed that these flies carry DNA from various primate parasites, suggesting they could be spreading diseases between nonhuman primates, livestock, and humans in these biodiverse regions.

Article Abstract

Flies form high-density associations with human settlements and groups of nonhuman primates and are implicated in transmitting pathogens. We investigate the movement of nonhuman primate-associated flies across landscapes surrounding Kibale National Park, Uganda, using a mark-recapture experiment. Flies were marked in nine nonhuman primate groups at the forest edge ([Formula: see text] = 929 flies per group), and we then attempted to recapture them in more anthropized areas (50 m, 200 m and 500 m from where marked; 2-21 days after marking). Flies marked in nonhuman primate groups were recaptured in human areas (19/28,615 recaptured). Metabarcoding of the flies in nonhuman primate groups revealed the DNA of multiple eukaryotic primate parasites. Taken together, these results demonstrate the potential of flies to serve as vectors between nonhuman primates, livestock and humans at this biodiverse interface.

Arbovirus surveillance in marmosets (Callithrix spp.) that live close to humans helps identify viral circulation in the environment and contributes to public health. We investigated the exposure to arboviral infections in 47 captive and free-living Callithrix from urban and peri-urban areas in the semiarid region of northeastern Brazil (SNB) in 2018.

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.

  • There's an urgent need to boost the effectiveness of seasonal influenza vaccines, with recombinant hemagglutinin showing potential benefits over traditional methods.
  • In a study, two adjuvants (Advax-CpG55.2 and alum-CpG55.2) were tested to see if they could improve the immune response of a quadrivalent influenza vaccine (QIV) in mice.
  • Results showed that the adjuvanted vaccines led to much higher levels of protective antibodies and significantly reduced illness in mice infected with the H1N1 strain, suggesting that this approach could be a better alternative for seasonal flu vaccinations.

Introduction: Ebola virus (EBOV) is a highly lethal RNA virus that causes severe hemorrhagic fever in humans and non-human primates. The lack of effective treatment or vaccine for this pathogen poses a serious threat to a global pandemic. Therefore, it is imperative to explore new drugs and therapies to combat this life-threatening infection.

mRNA delivered using lipid nanoparticles (LNPs) has become an important subunit vaccine modality, but mechanisms of action for mRNA vaccines remain incompletely understood. Here, we synthesized a metal chelator-lipid conjugate enabling positron emission tomography (PET) tracer labeling of LNP/mRNA vaccines for quantitative visualization of vaccine trafficking in live mice and non-human primates (NHPs).
