“Your #microbiome test says you’re in dysbiosis”? → Probably bullshit 💩.
Our paper shows how unregulated these analyses are. Time for validated, patient-safe diagnostics.

Recurrent Clostridioides difficile Infections This JAMA Insights discusses the epidemiology, diagnosis, and treatment of recurrent Clostridioides difficile infections.

#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.

#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.

#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.

Miao et al. link early-pregn ancy maternal gut microbiom e to preterm birth, identifying Clostridium innocuum and its estradiol-degra ding gene enriched in women with preterm birth. C. innocuum degrades estradiol and interacts with host genetics to amplify risk. These findings propose estradiol-degrad ing bacteria as predict ive biomarkers and therapeutic targets for preterm birth.

Researchers identify bacteria in the maternal gut microbiome linked to a higher risk of preterm birth. www.cell.com/cell-host-mi...

#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.
