Four strains belonging to the family of Methylobacteriaceae were isolated from different locations on the International Space Station (ISS) across two consecutive flights. Of these, three were identified as Gram-negative, rod-shaped, catalase-positive, oxidase-positive, motile bacteria, designated as IF7SW-B2T, IIF1SW-B5, and IIF4SW-B5, whereas the fourth was identified as Methylorubrum rhodesianum. The sequence similarity of these three ISS strains, designated as IF7SW-B2T, IIF1SW-B5, and IIF4SW-B5, was <99.4% for 16S rRNA genes and <97.3% for gyrB gene, with the closest being Methylobacterium indicum SE2.11T. Furthermore, the multi-locus sequence analysis placed these three ISS strains in the same clade of M. indicum. The average nucleotide identity (ANI) values of these three ISS strains were <93% and digital DNA-DNA hybridization (dDDH) values were <46.4% with any described Methylobacterium species. Based on the ANI and dDDH analyses, these three ISS strains were considered as novel species belonging to the genus Methylobacterium. The three ISS strains showed 100% ANI similarity and dDDH values with each other, indicating that these three ISS strains, isolated during various flights and from different locations, belong to the same species. These three ISS strains were found to grow optimally at temperatures from 25 to 30°C, pH 6.0 to 8.0, and NaCl 0 to 1%. Phenotypically, these three ISS strains resemble M. aquaticum and M. terrae since they assimilate similar sugars as sole carbon substrate when compared to other Methylobacterium species. Fatty acid analysis showed that the major fatty acid produced by the ISS strains are C18:1−ω7c and C18:1−ω6c. The predominant quinone was ubiquinone 10, and the major polar lipids were diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, and an unidentified lipid. Therefore, based on genomic, phylogenetic, biochemical, and fatty acid analyses, strains IF7SW-B2T, IIF1SW-B5, and IIF4SW-B5, are assigned to a novel species within the genus Methylobacterium,...

Mask up.
What?
Dr. Fauci will keep you apprised.
English Doc.....
We all know there is only ONE possible protection against these three ISS novel species belonging to the genus Methylobacterium — MASKS!!
When I read the headline I assumed that was one of the astronaut’s names.
It would be nice to know where (inside or outside) the samples were collected. Even then if collected outside would the samples result from crew contamination while doing EVA tasks?
There was an article on ZeroHedge about this, but ZeroHedge is banned here, so I posted the source journal article.
That which is outside (can’t believe it to be true) could easily be brought inside.
BREAKING: CDC and FauXi just announced that there
is a new mRNA-nanomaterial-quantumdot vaccine for this.
Just air the joint out.

I scanned the article. It did say one came off the HEPA filter. It mentioned where they found the others but I wasn’t that interested in remembering. My brain got full early.
FAR SIDE, the kid asked to be excused from class early because his brain was full
Why, its perfectly clear, isn’t it?
Methylobacterium
Meth
Lobstah
Bacteria
Ummm
That’s what my computer language translator comes up with...
Great movie great cast even that scary women scientist I saw it about a month ago it still gave me the hebegebes
Maybe we should send up a box of masks in the next supply ship. They protect you from everything. They might even want to wear two or more just to be safe.
