Selective and host-dependent tissue tropism of H5 HPAIVs from birds to mammals. Organs highlighted in red indicate sites of active viral replication and associated lesions.

Viral tropism manifests across living units, creating a mosaic of susceptible hosts, organs & cells that drives viral evolution, pathogenesis & diffusion. It is a cornerstone in the spread/spillover of avian influenza viruses. Get the story in #mBio: asm.social/2vX

Centers for Disease Control and Prevention (CDC). Reported cases of tick-borne diseases in the US from 2019 to 2022.

Various lab testing methodologies are available for diagnosis of tick-borne diseases, though the preferred approach varies. Learn about the epidemiology of tick-borne diseases in the U.S. and advances in the field of laboratory diagnostics in #JClinMicro: asm.social/2vN

(A) Suppose there are n subjects sampled at k time points respectively, and each sample of subjects has m features. The different sizes of the circles represent different sizes of abundance. (B) This table is a pseudo-matrix composed of curves, each representing the change in abundance of a certain feature of a subject during the sampling time points. (C) A series of distance matrices, each representing the distance between each subject in a different feature dimension. (D) The final distance matrix between each subject.

To address challenges associated with longitudinal microbiome analyses, researchers developed longitudinal microbial data distance (LorDist), an innovative method to model temporal microbial dynamics with enhanced precision. Learn more in #JournalSpectrum: asm.social/2vM

Deletion of the TM or HR region of the epsC gene causes a growth defect, while deletion of PDZ does not affect growth.

In #JBacteriology, researchers show that the C-terminal domain of the T2SS "clamp" protein EpsC is required for secretion of only a subset of substrates in Vibrio cholerae, adding to the growing body of evidence about substrate selection by the T2SS. asm.social/2vx

The potential role of microbiota on attachment-associated emotions (e.g., via oxytocinergic pathways) completes the core overlapping elements of our hypothesis. It is essential to acknowledge the complexity of other factors (e.g., environmental, socio-cultural, and other axes, such as the hypothalamic-pituitary-adrenal axis and cortisol) that influence human emotions and gut microbiomes.

#MicrobiologyMonday: What is love?♥️ It might start in the gut. This #mSystems paper explores the hypothesis that gut microbes can influence the hormonal and neural systems linked to love-associated emotions via the microbiota-gut-brain axis. Read now: asm.social/2vw
