Reducing the threats of rodent-borne zoonoses requires an understanding and leveraging of three key pillars: disease ecology, synanthropy, and rodentation.

Rodents have co-existed with humans for centuries, and frequently exchange pathogens. Historically, rodent-driven plague outbreaks scoured the Old World, resulting in substantial human mortality. Although such pandemics have not occurred for centuries, serious threats from rodent-borne infections, such as the global emergence of mpox, still exist.

Towards a 'people and nature' paradigm for biodiversity and infectious disease.

Zoonotic and vector-borne infectious diseases are among the most direct human health consequences of biodiversity change. The COVID-19 pandemic increased health policymakers' attention on the links between ecological degradation and disease, and sparked discussions around nature-based interventions to mitigate zoonotic emergence and epidemics. Yet, although disease ecology provides an increasingly granular knowledge of wildlife disease in changing ecosystems, we still have a poor understanding of the net consequences for human disease.

Child and adolescent foraging: New directions in evolutionary research.

Young children and adolescents in subsistence societies forage for a wide range of resources. They often target child-specific foods, they can be very successful foragers, and they share their produce widely within and outside of their nuclear family. At the same time, while foraging, they face risky situations and are exposed to diseases that can influence their immune development.

VESPA: an optimized protocol for accurate metabarcoding-based characterization of vertebrate eukaryotic endosymbiont and parasite assemblages.

Protocols for characterizing taxonomic assemblages by deep sequencing of short DNA barcode regions (metabarcoding) have revolutionized our understanding of microbial communities and are standardized for bacteria, archaea, and fungi. Unfortunately, comparable methods for host-associated eukaryotes have lagged due to technical challenges. Despite 54 published studies, issues remain with primer complementarity, off-target amplification, and lack of external validation.

Human behaviors driving disease emergence.

Interactions between humans, animals, and the environment facilitate zoonotic spillover-the transmission of pathogens from animals to humans. Narratives that cast modern humans as exogenous and disruptive forces that encroach upon "natural" disease systems limit our understanding of human drivers of disease. This review leverages theory from evolutionary anthropology that situates humans as functional components of disease ecologies, to argue that human adaptive strategies to resource acquisition shape predictable patterns of high-risk human-animal interactions, (2) humans construct ecological processes that facilitate spillover, and (3) contemporary patterns of epidemiological risk are emergent properties of interactions between human foraging ecology and niche construction.

A systematic mapping review of links between handling wild meat and zoonotic diseases.

1.Hunting, trade, and consumption of wildlife present a serious threat to global public health as it places humans in close contact with zoonotic pathogens.2.

Zootherapy as a potential pathway for zoonotic spillover: a mixed-methods study of the use of animal products in medicinal and cultural practices in Nigeria.

Background: Understanding how and why people interact with animals is important for the prevention and control of zoonoses. To date, studies have primarily focused on the most visible forms of human-animal contact (e.g.

Typical intracranial myiasis in Nigerian red river hogs () caused by an unknown bot fly (Diptera: Oestridae).

We report an unknown taxon of bot fly (Diptera: Oestridae: Oestrinae) in red river hogs ( Linnaeus, 1758) in Cross River State, Nigeria. From direct observation and interviews with local hunters, we document that, remarkably, the parasite typically occurs within the intracranial supra-meningeal space - i.e.

Eating Bushmeat Improves Food Security in a Biodiversity and Infectious Disease "Hotspot".

Hunting and consumption of wild animals, colloquially known as "bushmeat," is associated with health trade-offs. Contact with wildlife increases exposure to wildlife-origin zoonotic diseases yet bushmeat is an important nutritional resource in many rural communities. In this study, we test the hypothesis that bushmeat improves food security in communities that hunt and trade bushmeat regularly.

Primate reinfection with gastrointestinal parasites: behavioural and physiological predictors of parasite acquisition.

Infectious disease transmission is a cost of sociality in humans and other animals. Nevertheless, the mechanisms linking social behaviour to infection risk are poorly known. We conducted a field experiment to examine how host intrinsic traits, behaviour and physiology affect infection of nonhuman primates with gastrointestinal parasites.

Demography and health of "village dogs" in rural Western Uganda.

"Village dogs" in developing economies are assumed to be heavily burdened by infectious disease. We followed a cohort of 61 village dogs in rural western Uganda prospectively for fifteen months to measure changes in health and demographic outcomes, and to examine risk factors for morbidity and mortality. The mean (±standard deviation) number of dogs per household was 2.

Combining Footwear with Public Health Iconography to Prevent Soil-Transmitted Helminth Infections.

Shoes are effective for blocking soil-transmitted helminths (STHs) that penetrate the skin. Unfortunately, shoe-wearing is uncommon in many areas where STHs are prevalent, in part because local populations are unaware of the health benefits of wearing shoes. This is especially true in low-literacy populations, where information dissemination through written messages is not possible.

Social Behaviours and Networks of Vervet Monkeys Are Influenced by Gastrointestinal Parasites.

Substantial research has shown that while some parasite infections can be fatal to hosts, most infections are sub-clinical and non-lethal. Such sub-clinical infections can nonetheless have negative consequences for the long-term fitness of the host such as reducing juvenile growth and the host's ability to compete for food and mates. With such effects, infected individuals are expected to exhibit behavioural changes.

Changes in physiological stress and behaviour in semi-free-ranging red-capped mangabeys (Cercocebus torquatus) following antiparasitic treatment.

Parasites are ubiquitous in wildlife populations, but physiological and behavioural responses of hosts to infection are difficult to measure. We experimentally treated semi-free-ranging red-capped mangabeys (Cercocebus torquatus) in Nigeria with antiparasitic drugs and examined subsequent changes in glucocorticoid production and individual behaviour. Because both parasites and stress impact energy balance and health, we measured (i) behavioural time re-allocation via activity budgets, (ii) social relationships (e.

Lung fluke (Paragonimus africanus) infects Nigerian red-capped mangabeys and causes respiratory disease.

Eggs of the lung fluke genus Paragonimus were detected in red-capped mangabeys (Cercocebus torquatus) in Nigeria. We assess the role of these primates as potential sylvatic hosts and the clinical effects of the parasite on monkeys. DNA sequenced from eggs in feces were 100% identical in the ITS2 region to Paragonimus africanus sequences from humans in Cameroon.

Drivers of bushmeat hunting and perceptions of zoonoses in Nigerian hunting communities.

Bushmeat hunting threatens biodiversity and increases the risk of zoonotic pathogen transmission. Nevertheless, limited information exists on patterns of contact with wildlife in communities that practice bushmeat hunting, especially with respect to social drivers of hunting behavior. We used interview responses from hunters and non-hunters in rural hunting communities in Nigeria to: 1) quantify contact rates with wildlife, 2) identify specific hunting behaviors that increase frequency of contact, 3) identify socioeconomic factors that predispose individuals to hunt, and 4) measure perceptions of risk.

Captive-born cotton-top tamarins (Saguinus oedipus) respond similarly to vocalizations of predators and sympatric nonpredators.

What types of cues do callitrichid primates use to detect and respond to predators? Do they respond to predator-specific cues or to more general cues? The evidence for these questions remains conflicting. We presented captive-born and reared cotton-top tamarins with no previous exposure to predators (or predator cues) with vocalizations from three potential predators of cotton-top tamarin in the wild (white hawk, jaguar, and tayra) and with vocalizations from sympatric nonpredators (black-faced antthrush and red howler monkey). Vocalizations from predators and from nonpredator mammals elicited equivalent arousal, fear, and vocal responses.
