The microbiome includes both “mutualist” and “pathogen” microbes, regulated by the same innate immune architecture. A major question has therefore been: how do hosts prevent pathogenic infections while maintaining beneficial microbes? One idea suggests hosts can selectively activate innate immunity upon pathogenic infection, but not mutualist colonisation. Another idea posits that hosts can [...]

Environmental insults and compensative responses: when microbiome meets cancer

Tumor microenvironment has recently been ascribed a new hallmark – the polymorphic microbiome. Accumulating evidence regarding the tissue specific territories of tumor-microbiome have opened new and interesting avenues. A pertinent question is regarding the functional consequence of the meeting of the host-microbiome with cancer. Given microbial communities have predominantly been explored [...]

How do monomorphic bacteria evolve? The Mycobacterium tuberculosis complex and the awkward population genetics of extreme clonality

Exchange of genetic material through sexual reproduction or horizontal gene transfer is ubiquitous in nature. Among the few outliers that rarely recombine and mainly evolve by de novo mutation are a group of deadly bacterial pathogens, including the causative agents of leprosy, plague, typhoid, and tuberculosis. The interplay of evolutionary processes is poorly understood in these organisms. [...]

The Global Forest Health Crisis: A Public Good Social Dilemma in Need of International Collective Action

Society is confronted by interconnected threats to ecological sustainability. Among these is the devastation of forests by destructive non-native pathogens and insects introduced through global trade, leading to the loss of critical ecosystem services and a global forest health crisis. We argue that the forest health crisis is a public good social dilemma and propose a response framework that [...]

Source and seasonality of epizootic mycoplasmosis in free-ranging pronghorn (Antilocapra americana)

Mycoplasma bovis is an economically important bacterial pathogen of cattle and bison that most commonly causes pneumonia, polyarthritis and mastitis. M. bovis is prevalent in cattle and commercial bison; however, infections in other species are rare. In early 2019, we identified M. bovis in free-ranging pronghorn (Antilocapra americana) in northeastern Wyoming, USA. Here we report on additional [...]

On May 16, 2020, the Center for Academic Research and Training in Anthropogeny organized the symposium “Impact of Infectious Disease on Humans and Our Origins”. The symposium aimed to gather experts on infectious diseases in one place and discuss the interrelationship between different pathogens and humans in an evolutionary context. The talks discussed topics including SARS-CoV-2, dengue and [...]

Evolutionary Pathways and Trajectories in Antibiotic Resistance

Fernando Baquero, Jose L Martinez, Jeronimo Rodriguez-Beltrán, et al.

Subjects: Life Sciences, Medicine and Health Sciences, Microbiology, Pathogenic Microbiology

Evolution is the hallmark of life. Descriptions of the evolution of microorganisms have provided a wealth of information, but knowledge regarding “what happened” has precluded a deeper understanding of “how” evolution has proceeded, as in the case of antimicrobial resistance. The difficulty in answering the “how” question lies in the multihierarchical dimensions of evolutionary processes, nested [...]

Ecological Countermeasures for Pandemic Prevention: When Ecological Restoration is a Human Health Imperative

Ecological restoration should be regarded as a public health service. Unfortunately, the lack of quantitative linkages between environmental and human health has limited recognition of these principle. Advent of COVID-19 pandemic provides the impetus for the further discussion. We propose ecological countermeasures as highly targeted, landscape-based interventions to arrest the drivers of land [...]
