Neuronal Basis and Diverse Mechanisms of Pathogen Avoidance in Caenorhabditis elegans [PDF]
Frontiers in ImmunologyPathogen avoidance behaviour has been observed across animal taxa as a vital host-microbe interaction mechanism. The nematode Caenorhabditis elegans has evolved multiple diverse mechanisms for pathogen avoidance under natural selection pressure.

Antagonism Between Neuropeptides and Monoamines in a Distributed Circuit for Pathogen Avoidance
Cell ReportsSummary: Pathogenic infection elicits behaviors that promote recovery and survival of the host. After exposure to the pathogenic bacterium Pseudomonas aeruginosa PA14, the nematode Caenorhabditis elegans modifies its sensory preferences to avoid the ...

Pathogen avoidance and prey discrimination in ants [PDF]
Royal Society Open Science, 2020 Insect societies have developed sanitary strategies, one of which is the avoidance of infectious food resources as a primary line of defence. Using binary choices, we investigated whether Myrmica rubra ants can identify prey that has been artificially ...

Compressed sensing-based approach identifies modular neural circuitry driving learned pathogen avoidance [PDF]
eLifeAn animal’s survival hinges on its ability to integrate past information to modify future behavior. The nematode Caenorhabditis elegans adapts its behavior based on prior experiences with pathogen exposure, transitioning from attraction to avoidance of ...

Regulator of Lipid Metabolism NHR-49 Mediates Pathogen Avoidance through Precise Control of Neuronal Activity [PDF]
CellsPrecise control of neuronal activity is crucial for the proper functioning of neurons. How lipid homeostasis contributes to neuronal activity and how much of it is regulated by cells autonomously is unclear.

TRPM channels mediate learned pathogen avoidance following intestinal distention [PDF]
eLife, 2021 Upon exposure to harmful microorganisms, hosts engage in protective molecular and behavioral immune responses, both of which are ultimately regulated by the nervous system. Using the nematode Caenorhabditis elegans, we show that ingestion of Enterococcus

Early-life experience and disease exposure affect pathogen avoidance behaviour in macaquesEarly-life experience and disease exposure affect pathogen avoidance behaviour in macaques [PDF]
Royal Society Open SciencePathogens exert strong selective pressure on group-living primates. In humans, disease defence includes both a biological and behavioural immune system, which includes the emotion of disgust and avoidance behaviours shaped by genetics, learning and ...

Situational pathogen avoidance mediates the impact of social connectedness on preventive measures during the COVID-19 pandemic [PDF]
Scientific Reports, 2023 During the COVID-19 pandemic, physical distancing was one of the more important behaviours for reducing the spread of the virus. The present study investigated the influence on pathogen avoidance of familiarity with other people at private gatherings ...
