PLoS Pathogens, 2021 Yersinia murine toxin (Ymt) is a phospholipase D encoded on a plasmid acquired by Yersinia pestis after its recent divergence from a Yersinia pseudotuberculosis progenitor. Despite its name, Ymt is not required for virulence but acts to enhance bacterial

Flea infestation on small wild mammals in Gharyan, Northwest Libya [PDF]
Open Veterinary Journal, 2022 Background: Fleas play a major role as vectors for many pathogens that affect humans and livestock. Wild animals, especially wild rodents, are the most important hosts, acting as reservoir hosts for many flea species and pathogens.

The Diverse Roles of the Global Transcriptional Regulator PhoP in the Lifecycle of Yersinia pestis
Pathogens, 2020 Yersinia pestis, the causative agent of plague, has a complex infectious cycle that alternates between mammalian hosts (rodents and humans) and insect vectors (fleas). Consequently, it must adapt to a wide range of host environments to achieve successful

Flea-Associated Bacterial Communities across an Environmental Transect in a Plague-Endemic Region of Uganda. [PDF]
PLoS ONE, 2015 The vast majority of human plague cases currently occur in sub-Saharan Africa. The primary route of transmission of Yersinia pestis, the causative agent of plague, is via flea bites. Non-pathogenic flea-associated bacteria may interact with Y.

PLoS Neglected Tropical Diseases, 2011 BackgroundFrom 1990 to 2006, fifty-five natural villages experienced at least one plague epidemic in Lianghe County, Yunnan Province, China. This study is aimed to document flea abundance and identify predictors in households of villages with endemic ...

New Michigan Tick (Acari: Ixodidae) and Flea (Siphonaptera: Ceratophyllidae) Records From Colonial Nesting Birds [PDF]
, 2018 Banding and censusing large numbers of gull chicks over a 30-year period on Great Lakes islands has produced a collection of five individual ticks from two Herring Gull (Larus argentatus) chicks.

A refined model of how Yersinia pestis produces a transmissible infection in its flea vector
PLoS Pathogens, 2020 In flea-borne plague, blockage of the flea's foregut by Yersinia pestis hastens transmission to the mammalian host. Based on microscopy observations, we first suggest that flea blockage results from primary infection of the foregut and not from midgut ...

PLoS Neglected Tropical Diseases, 2020 Yersinia pestis, the causative agent of plague, is a highly lethal pathogen transmitted by the bite of infected fleas. Once ingested by a flea, Y. pestis establish a replicative niche in the gut and produce a biofilm that promotes foregut colonization ...

Parasitology, 2023 We investigated phylogenetic patterns in flea assemblages from 80 regions in 6 biogeographic realms and asked whether (a) flea phylogenetic turnover is driven by host phylogenetic turnover, environmental dissimilarity or geographic distance; (b) the ...

Molecular dynamics simulation of entanglement spreading in generalized hydrodynamics [PDF]
, 2020 We consider a molecular dynamics method, the so-called flea gas for computing the evolution of entanglement after inhomogeneous quantum quenches in an integrable quantum system.
