What causes viral transmission bottlenecks? This study uses barcoded virions to show that in the case of #influenza A #virus, early within-host replication dynamics (rather than a reduced inoculum population) drive loss of diversity during transmission @plosbiology.org 🧪 plos.io/4ngicDK
Population diversity declines between inoculated and exposed guinea pigs. Viral titers in nasal lavage samples are indicated by the overall height of the bar. Red lines show LOD (50 PFU/mL). Colors within the bars represent unique barcodes, and the height of each color indicates barcode frequency within the sample. Plots for individual animals are paired with those of their cage mate. Representative pairs for direct contact (top half) and aerosol (bottom half) exposure are shown from three experimental replicates. Guinea pig ID numbers are shown in the upper right corner of each plot.

New preprint from the CompMicroLab @ Umeå University! We looked at Salmonella from imported poultry meat in South Africa. Some of them had an unusual (for Salmonella) beta-lactam resistance allele that we think is from E. Coli! @scilifelab.se #microsky #genomics #phylogenetics #microbiology 🧪🧬🖥️

So - it happened. I was so excited to have found what was supposed to be my amazing long-term position and promising career pivot from bench to communications at the NIH. Unfortunately, I got the letter that so many others did. Several days of introspection, however, have yielded an idea: 1/n

So one of the things that I think is lost on AI proponents is what I call the card catalog effect, a thing I shouldn’t call it because a lot of people probably have no experience with a card catalog.

Happy Black History Month! I’m not sure if ASM is celebrating this year, so I’ll share some links to ASM resources I had previously collated on black women in microbiology that are now deleted (or at risk of being deleted). Deleted content can be viewed via the internet archive (links provided).

Well the award for most cowardly, boot-lickingest academic society has squarely gone to the American Society of Microbiology, who has taken down features of various non-white scientists. Absolutely pathetic behavior. Those articles are now coming up as “under review”. Truly sickening cowardice here.

Make the government make you take down articles @asm.org Don’t do it in advance as a precaution because of loss if funding or whatever. Hell, I would’ve paid way higher membership dues if I knew it would help you take a stand and if you gave us that choice vs whatever this is. Now, not so much

Ok this is not ok. ASM actively sought out BMA and its members for Juneteenth and Black History month content for the last 4 years. Actively asked for black labor and then takes it down?! @asm.org this is unacceptable. You should be standing up for marginalized microbiologists not erasing them.
