Will this be on TWiX?
I recognized Dr. Hotez’s name from TWiP.
I’ve read that the Biblical plagues of Egypt were based on an actual flood and its disease aftermath.

Dear TWiM team,
My name is Roman, I am a bioinformatics enthusiast from Odessa, Ukraine.
I’ve been listening to TWiM for 1.5 years now, and recently also to TWiV.
Inspired by you, I decided to record my own bioscience podcast, “the bioinformatics chat”.
On the most recent, 9th, episode, I was joined by Michael Tessler from the American Museum of Natural History and Christopher Mason from Weill Cornell Medicine. We discussed the discrepancies in microbial diversity when measured by the 16S amplicon sequencing versus shotgun sequencing.
It’s a bit technical, but I thought some of you and your listeners may find it interesting. The episode is at https://bioinformatics.chat/16S-vs-shotgun
Thanks for the great show!
RE: TWiM 159, immunophage synergy
Fascinating study. 1 question.
You talk a lot about adaptive vs innate immunity, but is there anything peculiar about mucosal immunity in particular that could shed light on the results?
IgA vs. IgG*

Microbiome analysis and confocal microscopy of used kitchen sponges reveal massive colonization by Acinetobacter, Moraxella and Chryseobacterium species
What about using bleach along with the dishwashing liquid when washing dishes? That’s for every time dishes are cleaned — not just for occasional sanitation of the sponge. In addition, once a week the sponge is replaced.
I raise cage birds and started using the bleach to minimize the risk of a disease spreading from one bird to the whole group through washing the food and water cups.

many thanks for your interest.
Our study suggests that keeping and continuously cleaning a kitchen sponge for too long, might lead to a microbial community inside the sponge that contains higher shares of potentially pathogenic bacteria.
Classical sponge cleaning techniques (e.g., boiling in hot water, cleaning in a washing machine at > 60°C using a solid detergent with bleach) will surely lead to a significant germ reduction in the sponges, which is definitely good (for the moment). However, in view of local germ densities of more than 50 billions per cm 3 , organized in hard-to-destroy biofilm like structures, and since killing curves usually can be described with negative exponential functions, it is always likely that some (more resistant) germs will survive even the harshest treatments and grow up again to a community with a higher share of potential pathogens.
Based on our study we therefore recommend that – instead of keeping your sponge for too long and cleaning it only ineffectually – one should regularly replace it, in particular and more often when you live/work in a hygiene-sensitive area (hospital, cafeteria…) or if you have ill/immunocompromised (old) people at home.
However, after having used them in the kitchen, you might surely use older sponges in other areas of your house, where hygiene is less important than in the kitchen (where food is prepared), e.g. to clean the bathroom/toilet or for garden work.
I hope my answers help a bit!
Best regards, Markus
