Solving the “small outbreak problem” in climate epidemiology
Published: 2024-01-05
Subjects: Climate, Diseases, Ecology and Evolutionary Biology, Entomology, Environmental Public Health, Epidemiology, Life Sciences, Microbiology, Parasitic Diseases, Public Health, Virus Diseases
Climate change can cause outbreaks of infectious diseases in unfamiliar locations — but how do we know which unusual outbreaks are the result of climate change? Scientists often hesitate to guess, leaving the task to journalists or the public. All of these audiences would benefit from a clear and consistent framework for thinking about causality, especially in situations where outbreaks are too [...]

The untapped potential of phage model systems as therapeutic agents
Published: 2023-07-28
Subjects: Biology, Evolution, Life Sciences, Medical Microbiology, Microbiology
With the emergence of widespread antibiotic resistance, phages are an appealing alternative to antibiotics in the fight against multidrug-resistant bacteria. Over the past few years, many phages have been isolated from various environments to treat bacterial pathogens. While isolating novel phages for treatment has had some success for compassionate use, developing novel phages into a general [...]
Breaking the Ice: A Review of Phages in Polar Ecosystems
Published: 2023-05-29
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Microbiology
Bacteriophages, or phages, are viruses that infect and replicate within bacterial hosts, playing a significant role in regulating microbial populations and ecosystem dynamics. However, phages from extreme environments such as polar regions remain relatively understudied due to challenges like restricted ecosystem access and low biomass. Understanding the diversity, structure, and functions of [...]
Building a Queer- and Trans-Inclusive Microbiology Conference
Published: 2023-05-03
Subjects: Gender Equity in Education, Microbiology
Microbiology conferences can be powerful places to build collaborations and exchange scientific thought, but for queer and transgender (trans) scientists they can also become sources of alienation and isolation. Many conference organizers would like to create welcoming and inclusive events but feel ill-equipped to make this vision a reality, and a historical lack of representation of queer and [...]
Breaking down microbial hierarchies
Published: 2023-03-21
Subjects: Ecology and Evolutionary Biology, Life Sciences, Microbiology
Microbial communities that degrade natural polysaccharides are thought to have a hierarchical organization and one-way positive interactions from higher to lower trophic levels. Daniels et al. have recently shown that reciprocal interactions between trophic levels can occur and that these interactions change over the duration of a batch culture.
How do microbes grow in nature? The role of population dynamics in microbial ecology and evolution
Published: 2023-02-26
Subjects: Ecology and Evolutionary Biology, Environmental Microbiology and Microbial Ecology Life Sciences, Evolution, Life Sciences, Microbiology, Systems Biology
The growth of microbial populations in nature is dynamic, as the cellular physiology and environment of these populations change. Population dynamics have wide-ranging consequences for ecology and evolution, determining how species interact and which mutations fix. Understanding these dynamics is also critical for clinical and environmental applications in which we need to promote or inhibit [...]
Psychological and Cultural Factors Influencing Antibiotic Prescription
Published: 2023-01-20
Subjects: Life Sciences, Medicine and Health Sciences, Microbiology, Psychiatry and Psychology
Humans have been giving a selective advantage to antibiotic-resistant bacteria worldwide by inundating the environment with antimicrobials for about one century. As a result, the efficacy of antibiotics has been impaired. Antibiotic resistance is a public health problem, responsible for increases in mortality and extended stays at hospitals. Hospitals and other clinical settings have implemented [...]
Psychological and Cultural Factors Influencing Antibiotic Prescription

Subjects: Biology, Economics, Geography, Life Sciences, Medicine and Health Sciences, Microbiology, Psychiatry and Psychology, Psychology, Public Health, Social and Behavioral Sciences
Humans have inundated the environment worldwide with antimicrobials for about one century, giving selective advantage to antibiotic-resistant bacteria. Therefore, antibiotic resistance has become a public health problem responsible for increased mortality, and extended hospital stays because the efficacy of antibiotics has diminished. Hospitals and other clinical settings have implemented [...]
When bacteria are phage playgrounds: interactions between viruses, cells and mobile genetic elements
Published: 2022-07-02
Subjects: Ecology and Evolutionary Biology, Genetics and Genomics, Life Sciences, Microbiology
Studies of viral adaptation have focused on the selective pressures imposed by hosts. However, there is increasing evidence that interactions between viruses, cells, and other mobile genetic elements (MGEs) are determinant to the success of infections. These interactions are often associated with antagonism and competition, but sometimes involve cooperation or parasitism. They involve mechanism [...]

Scaling up and down: movement ecology for microorganisms
Published: 2022-06-20
Subjects: Ecology and Evolutionary Biology, Life Sciences, Microbiology
Movement is critical for the fitness of organisms, both large and small. It dictates how individuals acquire resources, evade predators, exchange genetic material, and respond to stressful environments. Movement also influences ecological and evolutionary dynamics at scales beyond the individual organism. However, the links between individual motility and the processes that generate and maintain [...]
A minimum data standard for vector competence experiments
Published: 2022-06-15
Subjects: Bioinformatics, Entomology, Life Sciences, Microbiology, Virology
The growing threat of vector-borne diseases, highlighted by recent epidemics, has prompted increased focus on the fundamental biology of vector-virus interactions. To this end, experiments are often the most reliable way to measure vector competence (the potential for arthropod vectors to transmit certain pathogens). Data from these experiments are critical to understand outbreak risk, but – [...]
Gut microbiota repeatability is contingent on temporal scale and age in wild meerkats
Published: 2022-03-29
Subjects: Life Sciences, Microbiology, Other Microbiology
Inter-individual differences in gut microbiota composition are hypothesized to generate variation in host fitness – a premise for the evolution of host-gut microbe symbioses. However, recent evidence suggests that gut microbial communities are highly dynamic, challenging the notion that individuals harbour unique and stable gut microbial phenotypes. Leveraging a long-term dataset of wild [...]
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 [...]
