If you're wondering why so many Bat coronaviruses seem to emerge from one research group in China, this paper provides a clue.

pubmed.ncbi.nlm.nih.gov/26920708/

It involves our usual friends... and a "novel" bat coronavirus called 4991
There is just a little itty bit of a problem.
In "discovering" Bat Cov-4991 they didn't actually discover a virus.
More likely, they made one.
You see, they published complete gene sequences of the "bat viruses" in their paper, including spike sequences.

But not 4991.
Oh no, they didn't happen to have the complete sequence of that one. Just the RdRp.

52. Update - @quay_dr exposes more RaTG13 fraud

The seminal paper from WIV claiming SARS-CoV-2 probably originated in bats appears to contain a contrived specimen, incomplete & inaccurate genomic assembly, & the signature of lab-derived synthetic biology

54. New #RaTg13 paper from @stvevenemassey

Exclusive to #DRASTIC

SARS-CoV-2's closest relative, RaTG13 was generated from a bat transcriptome not a fecal swab

Implications for the origin of COVID-19

One last thread on the origins of #SARSCoV2 before the upcoming publication of the US intelligence report. First of all, there are two things that might be even more important than the origin itself: research ethics and scientific debate. 1/
Since the beginning, some scientists working in Chinese institutions haven't been fully transparent. The history of #RaTG13 and the issues with its sequencing data, the miners pneumonia, the missing database, the pangolin CoV data. Hiding info, playing with words. Bad science. 2/
The second thing that I didn't like was the suppression of an open dialogue between scientists, which lasted for several months. Now it's easier for scientists to freely talk about the different scenarios, but do you remember how difficult it was one year ago? 3/

The study identifying #RaTG13 was partially supported by NIH grant:R01AI110964 (link.springer.com/article/10.100…). US taxpayers' money was used for collecting/studying coronavirus samples from Mojiang mineshaft! @congressdotgov has the right/obligation to investigate this! @USRightToKnow Image

Question for bioinformaticians! Believe it or not, the first genome of bat virus #RaTG13 had some nucleotides that were supported by zero reads: in other words, the genome didn't match the sequences that were used to assemble it. How is it possible? 1/
#originsofSARSCoV2
Assemblers are computer programs, they do not "invent" nucleotides. So, what happened here? My explanation was that this genome was assembled using other reads, maybe in addition to the ones that were uploaded. 2/
In that case, I expected the authors to upload the missing reads.. Instead they did the opposite: they updated the genome, replacing the nucleotides supported by zero reads with the correct ones. So, the question is: how the heck did they assemble the genome the first time? 3/

Some "conspiracists" always get it right!

Conspiracist, January 2020: "#RaTG13 virus looks like BtCoV/4991 described in an old paper that you didn't cite!" 📄

Average scientist, January 2020: 😴

Shi Zhengli, July 2020: "Yes, it was the same virus."

Conspiracist, May 2020: "Look, these sequences in database are dated 2017/2018. So you didn't sequence RaTG13 this year, as you wrote in the paper!" 🔬

Average scientist, May 2020: 😴

Shi Zhengli, July 2020: "Yes, actually we got the sequence in 2018."

2/
Conspiracist, May 2020: "Have a look at these Chinese theses we found on the internet: RaTG13 was found in a #mineshaft were people died of #pneumonia!" 😱

Average scientist, May 2020: 😴

Shi Zhengli, June 2020: "Oh yes we found it there, but.. well, the cause was a fungus"

La virologa cinese #LiMengYan dice che #SARSCoV2 è stato creato in un #laboratorio di #Wuhan. Senza vedere le prove (che lei sostiene di avere), mi risulta difficile credere alla sua tesi. 1/
nypost.com/2020/09/11/chi…
La scienziata, infatti, sostiene che #SARS2 sia una #chimera dei virus dei #pipistrelli ZC45 e ZXC21.

Ora, è vero che a Wuhan facevano chimere a scopi di ricerca, ma questi due virus sono troppo diversi da SARS2 per essere i suoi antenati diretti. 2/

Il nuovo #coronavirus infatti ha una similarità dell'87% con questi due virus, troppo poco per essere il risultato di una loro ricombinazione (il virus più simile a SARS2 è #RaTG13). 3/

RaTG13. A thread.
RaTG13, the Bat-Cov most similar to Sars-Cov-2, was conjured out of the hat in late January 2020. The sample was allegedly collected in 2013, though submitted to NCBI only on 27-Jan-2020 by ... Zheng-Li Shi. |1
#Coronavirus #covid19 #sarscov2 #CoronavirusFacts
On 03-Feb-2020 RaTG13 was presented in an Article published by Nature, received on 20-Jan-2020 , one week before RaTG13 was submitted to NCBI GenBank. |2
nature.com/articles/s4158…
I guess this is the reason why RaTG13 was invented. No one would have bought the story of a bat origin when the sequence identity is ~80%. |3

In this study, we have developed a fast and cost-effective method
for reverse genetics of coronaviruses by combining two approaches developed by others..As the genomes can be divided into multiple short fragments, mutations can be introduced into individual
fragments easily. ImageImageImageImage
