Salmonella[edit]

**Original** - A colour-enhanced scanning electron micrograph showing *Salmonella typhimurium* (shown in red), a species of **Salmonella**, invading cultured human cells

Reason: Microscopic shot, high resolution, pleasing to the eye, used prominently on a number of important articles. A good amount of detail. Not the kind of thing you see every day, I feel this will be a great addition to our FPs. Already featured on the Turkish Wikipedia.

Comment. What are the yellow folded structures? I assume that the red string-like structures are the flagellae, which to me look a bit disorganised probably due to processing. I think that the image description should be more complete for this image to be understood properly. Snowman (talk) 23:36, 8 February 2010 (UTC)[reply]
- I can only assume they're the skin cells. I'm sorry, I'm no expert; this merely jumped out at me as FP-material while I was reviewing a FPOC. J Milburn (talk) 01:11, 9 February 2010 (UTC)[reply]
  - Skin (keratinised stratified squamous epithelium) cells are probably about 50-100 times larger than these bacteria. I would like to know what the image shows. Snowman (talk) 12:00, 9 February 2010 (UTC)[reply]
    - The caption on the image page is word-for-word from the source website, and my caption is a modification of that. J Milburn (talk) 12:09, 9 February 2010 (UTC)[reply]
      - That does not mean that the image description is ideal. The image description says "invading cultured human cells", which I find a bit vague. By zooming in and out with the SEM it should be apparent to the observer what that yellow structures are. Snowman (talk) 12:19, 9 February 2010 (UTC)[reply]
        I could send an email? J Milburn (talk) 12:20, 9 February 2010 (UTC)[reply]
        I am not quite sure where to pitch my comment. This bacteria would grow on culture medium so there might have been a particular reason why they were grown on a human-cell culture for the SEM in question. If this image appeared in a journal, it presume the paper would also include how the specimen for SEM was prepared, including any materials used, what the human cells are, what parts of the human cells are seen, and the magnification or a scale. It would be interesting to learn why the flagella are tangled up - these are the structures that enable this bacteria to be motile and if find it difficult to see how they could do this in a tangled-up state. In this type of an image of a processed specimen it would be important to know what is artefact. I think as a minimum the image should have a scale (or magnification or indication of the size in the image description), what the yellow folded layers are, an explanation of the tangled-up flagella, and an explanation of any changes caused by processing and artefacts. I have nothing against this image becoming FP, when the image description is adequate. I have occasionally gone back to authors to find out more about images.

Support: Agreeing with nominator. (I appreciate the need for more detail regarding the image, but IMO is not currently affecting EV enough to wipe it out; there is enough information for it to be useful. With respect to the above, it appears to be a call for a cellular biologist or bacteriologist to teach us their field for the purpose of understanding a single image; would be great, but unrealistic.)

Support. I've thought about the arguments, and it actually seems to have rather high encyclopedic value as an illustration. Mostlyharmless (talk) 01:37, 15 February 2010 (UTC)[reply]
