Alternative lifestyles: A plague persistence hypothesis
Jeffrey Wimsatt, David A. Eads, Marc R. Matchett, Dean E. Biggins
2023, Ecosphere (14)
Several explanations have been posited for how the plague bacterium (Yersinia pestis) reemerges during sylvatic cycles within the same foci over many years, and often without direct evidence of host die-offs. One prevalent view is that transmission-optimized Y. pestis bacteria, exhibiting epizootic/enzootic behavior, almost continually replicate and survive through repeated, linked, host-centered...
