🧫 #BacterioMed Staphylococcus aureus in all its forms. The most observant 👀 will spot 3 distinct morphotypes, including a small-colony variant. Sputum from a #cysticfibrosis patient still requiring antibiotics despite triple therapy. A reminder that the infectious challenge remains very real in CF.

“Your #microbiome test says you’re in dysbiosis”? → Probably bullshit 💩. Our paper shows how unregulated these analyses are. Time for validated, patient-safe diagnostics. Science ≠ marketing. @sfmicrobiologie.bsky.social @jm-sfm.bsky.social @rejif-spilf.bsky.social 👉 doi.org/10.1136/gutj...

#BacterioMed Recurrent Clostridioides difficile infections affect 14%-16% of patients with CDI. Up to 50% of rCDI is caused by ingestion of spores from a new toxin-producing strain. FMT: after 2 or more CDI recurrences and first-line antibiotic treatment. jamanetwork.com/journals/jam...

#BacterioMed Uncommon antibiotype for Citrobacter farmeri, showing a hyper OXY-like profile. C. farmeri belongs to the Citrobacter amalonaticus group. ⚠️ Beware: immunochromatographic tests may misidentify it as CTX-M. This resistance in C. farmeri is chromosomally encoded. doi.org/10.1016/j.di...

#GramArt Nothing bacterial here. Just the quiet beauty of a blood smear, where staining artifacts sketch out something close to art. #BacterioMed

#BacterioMed Bacteremia caused by Lactobacillus plantarum (Lactiplantibacillus plantarum) in a patient who underwent digestive surgery. So glad to have had early identification right from the Gram stain: crucial for guiding probabilistic antibiotic therapy, given this species’ resistance profile.

Researchers identify bacteria in the maternal gut microbiome linked to a higher risk of preterm birth. www.cell.com/cell-host-mi... @cp-cellhostmicrobe.bsky.social #WestLakeUniversity Ju-Sheng Zheng & colleagues

#BacterioMed The mucoidy of P. aeruginosa can be seen right from the Gram for expert eyes. Note the thick gangue surrounding Gram-negative bacilli: it corresponds to the exopolysaccharides produced by the bacteria. It's easy to see why antibiotics are not very effective at this stage of 🫁infection.

The call of the ocean.
