How does Shiga toxin-producing E. coli affect the central nervous system? This #MMBRJournal review provides updates on the most recent findings, from both clinical and experimental perspectives. Read now: asm.social/2LH
Proposed action of Stx in the CNS: In the CNS, the Gb3 receptor is present in human endothelial cells and neurons. The mechanism of Stx-mediated damage in oligodendrocytes, astrocytes, and microglial cells has not been fully elucidated (question mark and blue arrows). Reactive astrogliosis and microgliosis under Stx exposure potentially affect oligodendrocyte and myelin integrity. When Stx enters the bloodstream, PMN cells produce and release pro-inflammatory cytokines TNF-α, IL-1β, and IL-6 (see Fig. 1). TNFα/IL-1B upregulates endothelial Gb3, thus generating greater susceptibility to Stx (70). Endothelium damage leads to interstitial edema.

C. difficile uses phase variation to generate phenotypically heterogeneous populations in the gut. This #JBacteriology study shows how interactions with E. faecalis lead to a marked shift in C. difficile phenotypes associated with phase variation. asm.social/2Lx
E. faecalis stimulates cmr-associated phenotypes in C. difficile. (A) SEM images from dual cultures of Cd or ΔcmrRΔcmrT Cd with Ef at a 1:1 ratio after 7 days of growth on surface motility plates. (B) Gram stains of Cd and ΔcmrRΔcmrT Cd in monocultures and dual cultures with Ef at a 1:1 ratio after 3 days of growth on BHIS plates. Representative images are shown at 60× magnification. (C) Quantification of cell length of Cd and ΔcmrRΔcmrT in mono- or dual culture with Ef at a 1:1 ratio after 3 days of growth on BHIS plates. Data presented as means with SD. ****P < 0.0001, two-way ANOVA. (D–E) Representative images of plates (D) and colony morphology (E) of Cd monoculture and dual culture with Ef after 7 days of growth.

How does E. coli age? According to this #mBio study, the the decisive factor driving growth decline in E. coli is not the presence of protein aggregates, but the fraction of the intracellular space they occupy. Learn more: asm.social/2KZ

The rationale for the recent updates to the U.S. childhood immunization schedule is at best uncertain and sets a potentially dangerous precedent for public health. Read our statement: asm.org/press-releas...
Protecting a country’s public health presents unique challenges that are specific to that country’s population. The prevalence of diseases in the U.S. is not the same as it is in other countries, and public health recommendations should be made based on the public health challenges faced by the American people.
