Microbiology News Roundup – September 2021

Coronavirus Latest

YouTube is starting to remove anti-vaccination information from its site.

The Video sharing platform YouTube has said it is going to start to remove content that spread misinformation and unchecked affects about vaccines and their affects.

130,000 videos were removed from its platform since last year including videos that claimed the covid vaccine will cause autism, cancer or infertility.

It’s been suggested that misinformation being spread on social media sites is largely to blame for anti-vaccine mentality and reluctancy to getting the covid vaccine. Other social media sites like Facebook and twitter have also implemented similar bans that will either remove or flag un verified claims about covid and the vaccine.


Lack of available GPs means that Face-to-Face doctors’ appointments are at a critically low level.

With GPs being spread incredibly thin due the effects of Covid-19 and the mass vaccination rollout, people have been unable to see there GPs face-to-face and often have to settle for a phone consultation or have had their appointment delayed several times.

Just 58% patients were seen face-to-face in August – the first full month following the ending of restrictions. That compares with 54% in January and over 80% before the pandemic.

Royal College of GPs chair Prof Martin Marshall said: “The workforce is simply not big enough to manage.” He said remote consultations did work for many, but added GP knew many more patients wanted to see their doctors face-to-face, particularly those with complex health needs.

As a result of limited GP appointment more and more people have been turning to A&E which is adding to wait times and causing more strain on the NHS.


Mesenchymal stromal cell-secreted CCL2 promotes antibacterial defence mechanisms

A study at Cornell University has discovered that Mesenchymal stromal cells (MSCs) which represent a clinically relevant translation animal model for human cutaneous wound healing, were recently found to possess antimicrobial properties against planktonic bacteria, and in the case of equine MSCs, also against biofilms.

“This study demonstrates that the mesenchymal stromal cell (MSC) secretome effectively reduced viability of the methicillin-resistant Staphylococcus aureus (MRSA) biofilms in an ex vivo cutaneous wound explant model. Moreover, MSC secretome could actively modulate immune responses of keratinocyte via a CCL2-mediated mechanism. For these studies, the equine model was used, which is a recognized translational and clinically relevant animal model for human wound healing. Collectively, these data further support the value of MSC secretome-based treatments for infected wounds.”


Baseline Gut Metagenomic Functional Gene Signature Associated with Variable Weight Loss

The Institute for Systems Biology in Seattle had recently reported that they have found links between gut microbiota and weight loss.

“Recent human feeding studies have shown how the baseline taxonomic composition of the gut microbiome can determine responses to weight loss interventions. However, the functional determinants underlying this phenomenon remain unclear. We report a weight loss response analysis on a cohort of 105 individuals selected from a larger population enrolled in a commercial wellness program, which included healthy lifestyle coaching. Each individual in the cohort had baseline blood metabolomics, blood proteomics, clinical labs, dietary questionnaires, stool 16S rRNA gene sequencing data, and follow-up data on weight change.”
