STC will be leaving the platform 𝕏 (formerly Twitter) in the near future. However, during the six years of @STCmicrobeblog on 𝕏, I read many interesting posts – in addition to the crap that social media brings (facepalm emoji). It would be a pity to lose my "bookmarks" and, since most of them were never the subject of a regular blog post, I want to share what I found. Therefore, at irregular intervals, I'll be sharing what I found – two or three tweets at a time – in a series I'm calling "Lost & Found." Here, then, is Lost & Found #1.

When I wrote the third piece on bacterial rosettes, ...rosette is a rosette. (3|3), I was tempted to include this beautiful image of Brevundimonas bacteroides rosettes shown by Amelia Randich in her tweet. Both Brevundimonas and Caulobacter are closely related stalked Alphaproteobacteria, but since this picture does not show how the cells stick together in rosettes via the holdfasts at the tip of their stalks, I decided on images of Caulobacter. So sorry, Amelia (@ameliarandich.bsky.social).

The first attempts to track bacterial cells during growth using suitable software were made about 20 years ago. Today, this is almost a routine exercise, and the program DeLTA 2.0 presented by Mary J. Dunlop here even "recognizes" and marks dividing cells (note the small “connectors” drawn in). This tweet was based on a preprint and discussed favourably on 𝕏. The paper has since been published.
Introducing DeLTA 2.0, which segments and tracks bacteria growing on two-dimensional surfaces. 1% error rate. Purely Python workflow. Preprint: https://t.co/dwBwwvtlbG Code: https://t.co/u1YI6eywsj

Fungi and lichens are particular favorites of all of us here at STC. And it has been a great pleasure, again and again, usually several times a week, to see photos by mushroom and lichen enthusiasts on 𝕏. Here is an example:
