Il est temps d'en finir avec la théorie qu'il n'y aurait pas de #virus ou qu'il n'y a pas de Covid.
Bien sûr que si, ils existent, ainsi que le SARSCov2. Ceux qui vous disent le contraire sont massivement désinformés.… Alors quels sont les arguments?suite⏬
La virologie ne sort pas de nulle part, elle s'est établie sur 100 ans d'observations. En science, l'hypothèse qui fonctionne le mieux gagne. Si on veut prouver que c'est faux, il faut DEMONTRER votre nouvelle hypothèse pour expliquer les données observées mieux que l'ancienne.⏬
Mais Kaufman, Cowan etc ne le font jamais. Ils disent seulement que les méthodes d'observation de virologie ne suivent pas LEURS standards. Ca me rappelle les nofake qui disent que seules les études randomisées sont acceptables. Mais c'est faux. Alors quels sont les arguments?⏬

We are delighted to announce the release of #PhageAI 0.10.0: extended repository and the new #phage #prediction tool: #chronic #lifecycle. 1/4
Each of the #phage genome has computed a new numerical vector representation by #Phage2Vec technology, re-classified #lifecycles and re-computed nearest neighborhood what introduced updated alignment-free top-10 similar #bacteriophages registry. 2/4
Furthermore, we released beta #bacteriophage #taxonomy #prediction tool.

Feel free to extend your account role from basic to Expert user using "My Profile" view, to access it from the @PhageAI. 3/4

Excited to see my first ever first-author paper and the first chapter of my dissertation out now in @ISMEJournal!

We did an exhaustive review/synthesis of what is known about the effects of community context on bacteria-phage ecology and evolution (spoiler: not much)

If you want a little more detail than a Twitter thread, you can check out a 'behind-the-paper' blog post we wrote here:…

There has been a long history of studying bacteria and their viral symbionts, #bacteriophages. In #ecology and #evolution, they've been workhorse systems for studying host-parasite interactions for many years (3/n)

How do we quantify how much #virus is in a sample (titre). We use a plaque assay, which is why he most commonly used method. Below is a graphical version I've made (on @BioRender) of how it is done in the lab.

But how do they work? - a thread
#SciComm #Virology #phdchat
Here is a photo of a #SARSCoV2 assay, the virus which causes #COVID19 ( Photo: Müller/Charité). The large areas which are clear are known as plaques which are caused by virus killing cells in a monolayer. More plaques = more virus titre

2/n SARS-COV2 plaque assay
The technique was originally developed for #Bacteriophages bit was adapted by Dulbecco in 1952 for animal #viruses. Viral stocks are dilutes 10 fold in series and placed onto a monolayer. After incubation a gel is placed on the layer, restricting infection to nearby cells
