Streamlining antibiotic use in community acquired pneumonia: A quality improvement initiative

Journal of Hospital Medicine, Volume 21, Issue 8, Page 890-897, August 2026.
Visual Abstract Abstract Background Evidence suggests a 3‐day total duration and early transition to oral therapy is safe in hospitalized patients with community acquired pneumonia (CAP)—though such care is not standard in the United States. To implement these evidence‐based practices, a multidisciplinary group led by a hospitalist and antimicrobial ...

Occurrence of Antimicrobial Resistance in Kocuria rhizophila Bacteria Isolated From Salmo munzuricus (Teleostei: Salmonidae) Samples in Natural Resources

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
This study examined the antibiotic susceptibility of Kocuria rhizophila isolated from Salmo munzuricus samples taken from the Munzur River. The isolates are resistant to Penicillin G, moderately susceptible to gentamicin and tetracycline, and highly susceptible to amoxicillin and ampicillin.

De novo or Salvage? Nucleotide Availability as a Driver of Bacterial Adaptation and Virulence

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Bacterial pathogens survive in different host environments by switching between making nucleotides by de novo synthesis and scavenging them from the host. This flexibility supports growth and virulence making nucleotide metabolism an attractive therapeutic target.

Seasonal Restructuring of Microbial Communities and Resistomes in the Shitalakshya River, Bangladesh Revealed by Shotgun Metagenomics

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Dry‐season pollutant concentration drives microbial restructuring in Bangladesh's Shitalakshya River, shifting communities from Myroides to stress‐tolerant genera while enriching metal resistance genes and efflux pumps, revealing non‐antibiotic co‐selection as a key driver of antimicrobial resistance in urban waters.

Comparative Analysis of Chlorhexidine Derivatives and Alternative Agents on Streptococcus mutans Viability, Biofilm Formation, and Gene Expression

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Chlorhexidine gluconate and alexidine potently kill S. mutans, disrupt biofilms, and downregulate virulence genes, yet show moderate cytotoxicity. In contrast, sub‐MIC amoxicillin paradoxically promotes biofilm formation, highlighting the need for targeted antibiofilm therapies. ABSTRACT This study evaluates the antimicrobial and antibiofilm effects of

One Health Insights From Pteropus medius: Nipah Virus Spillover, Microbiota, and Antimicrobial Resistance

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Environmental and anthropogenic drivers of antibiotic resistance dissemination. The cycle reinforces how anthropogenic inputs, such as sewage, animal dung, hospital effluent, and agricultural runoff bring resistant bacteria and antibiotic residues into soil and water.
