Using Selective Agar Containing Ciprofloxacin and Tetracycline Reveals Resistant Oral Microbiota in Healthy and Periodontitis Patients

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
Oral biofilms from healthy and periodontitis patients harbor diverse bacteria, including aerobes and obligate anaerobes. Using selective media with tetracycline or ciprofloxacin, 495 strains (106 species) were isolated. Resistance was common—32.9% to ciprofloxacin, 15.2% to tetracycline, 0.6% to ampicillin—highlighting the oral cavity as a reservoir ...

Non‐redox Lewis Acids Supported Pd‐Catalyzed C—C /C—H Activation and Accession to Produce Pharmaceutical Intermediates

ChemistryOpen, Volume 15, Issue 4, April 2026.
Palladium is a simple and versatile redox‐active metal that plays a crucial role in the oxidation reactions for organic synthesis and production of pharmaceutical intermediates. Notably, there has been significant progress with Lewis acids (LAs), which are non‐redox metal ions promoting Pd(II)‐catalyzed oxidation via C—H and C—C bond activation.

Global Analysis of the Co‐Occurrence of Antimicrobial and Metal Resistance Genes in Bacterial Genomes From Dairy‐Isolated Pathogens

Environmental Microbiology, Volume 28, Issue 4, April 2026.
Metal contamination in dairy systems drives antibiotic resistance through co‐selection. Analysis of 3303 genomes revealed 74% of isolates harbour more metal than AMR genes. Arsenic (arsB) and tetracycline (tet(38)) resistance co‐occur in 43% of bacteria, exhibiting nearly identical prevalence, suggesting a tight genetic linkage.
