Hi everyone! This is my first contribution to the daily digest, and I’ll follow others’ lead by starting with the latest preprints concerning Covid-19. Away from the ongoing pandemic, some of the highlights include a look at how commensal gut microbes interact with pathogens, and an insight into deep sea oceanic crust microbiomes.

It seems to be a relatively quiet day today, so I’ve included an article from the University of Bristol which looks at how nanoscopic pillars on the surface of some insect wings protect them against bacteria. Perhaps only loosely a microbiome paper, but it’s worth a read for its electron microscopy alone!

All the break-neck speed with which the progress that is happening today in tracking, detecting and treating the disease, like everything else, is owed in part to the giants whose shoulders we’re standing on. One such thing is the usage of serum (from recovered patients or derived elsewhere) for treatment. So, as a little tribute, I would like to share with you today, on the birthday of Dr. Hattie Elizabeth Alexander (born April 5, 1901), the information that she pioneered the work in using anti-influenzal rabbit serums to treat the then always-fatal influenzal meningitis (effectively bringing down the fatality rate to 20%!), and was also sone of the very first to study bacterial mutations that come along with antibiotic resistance !

So we’ve come a long way and are forging our way forward. Here are a few interesting articles that are slowly pushing this boundary, a piece at a time.

COVID-19

From PREDICT to prevention, one pandemic later – Colin J Carlson – The Lancet.

Legionella species: A potential problem associated with rain water harvesting systems? – Judith A Taylor et al – SAGE Journals

Bioinformatics

Applications of Machine Learning Predictive Models in the Chronic Disease Diagnosis – Gopi Battineni et al – Journal of Personalized Medicine

PS: I know, I am with you on this — the lockdown isn’t ideal. But we are also the generation, who for the first time can end articles signing off as “Stay Safe and Wash Your Hands” and manage to prevent a large proportion of its species from suffering / dying. Isn’t that crazy! Have a great day!
