Derivation of Escherichia coli O157:H7 from its O55:H7 precursor. [PDF]

PLoS ONE, 2010
There are 29 E. coli genome sequences available, mostly related to studies of species diversity or mode of pathogenicity, including two genomes of the well-known O157:H7 clone. However, there have been no genome studies of closely related clones aimed at

Escherichia coli O157 : H7 colonization in cattle following systemic and mucosal immunization with purified H7 flagellin [PDF]

Infection and Immunity, 2008
Escherichia coli O157:H7 is an important pathogen of humans. Cattle are most frequently identified as the primary source of infection, and therefore, reduction in E.

Immunization with H7-HCP-tir-intimin significantly reduces colonization and shedding of Escherichia coli O157:H7 in goats. [PDF]

PLoS ONE, 2014
Enterohemorrhagic Escherichia coli (EHEC) O157:H7 is the causative agent of hemorrhagic colitis and hemolytic uremic syndrome in humans. However, the bacterium can colonize the intestines of ruminants without causing clinical signs.

Inhibition of influenza H7 hemagglutinin-mediated entry.

PLoS ONE, 2013
The recent outbreak of H7N9 influenza in China is of high concern to public health. H7 hemagglutinin (HA) plays a critical role in influenza entry and thus HA presents an attractive target for antivirals.

Escherichia coli O157:H7

The Lancet, 1998
Escherichia coli O157 was first identified as a human pathogen in 1982. One of several Shiga toxin-producing serotypes known to cause human illness, the organism probably evolved through horizontal acquisition of genes for Shiga toxins and other virulence factors. E.

Analysis of the Role of Vaccinia Virus H7 in Virion Membrane Biogenesis with an H7-Deletion Mutant [PDF]

Journal of Virology, 2013
ABSTRACT Essential vaccinia virus genes are often studied with conditional-lethal inducible mutants. Here, we constructed a deletion mutant lacking the essential H7R gene (the ΔH7 mutant) with an H7-expressing cell line. Compared to an inducible H7 mutant, the ΔH7 mutant showed a defect at an earlier step of virion membrane biogenesis, before

Genetically similar strains of Escherichia coli O157:H7 isolated from sheep, cattle and human patients [PDF]

, 2012
Conclusions: The same pathogenic subtypes of VTEC O157:H7, including the highly virulent clade 8, appear to be present in both sheep and cattle in Sweden, suggesting strains can circulate freely between ruminant ...

Transforming Growth Factor-β3 Regulates Adipocyte Number in Subcutaneous White Adipose Tissue

Cell Reports, 2018
Summary: White adipose tissue (WAT) mass is determined by adipocyte size and number. While adipocytes are continuously turned over, the mechanisms controlling fat cell number in WAT upon weight changes are unclear.
