Holder vs Retort: How milk pasteurization shapes preterm infants’ gut health

Researchers at Vanderbilt University Medical Center found that pasteurization methods shape the gut microbiomes of preterm infants fed donor human milk. Holder pasteurization preserved microbial diversity and beneficial taxa better than Retort, producing microbiomes more similar to those from mothers’ own milk.

Rising threat of sexually transmitted gut infections demands stronger prevention strategies

It's time to develop more effective ways to control and prevent sexually transmitted gut infections, urge the authors of an article appearing today in Clinical Microbiology Reviews, a journal of the American Society of Microbiology.

Gut bacteria and insomnia influence each other in small but significant ways, study shows

Scientists used Mendelian randomisation to explore the two-way relationship between gut microbiota and insomnia, analyzing GWAS data from over 386,000 individuals and two major microbiome cohorts. The study found only limited taxa surviving strict correction, suggesting small but causal links that highlight the gut–brain axis in sleep health.

Gut bacteria in mothers and newborns may shape infants’ risk of early respiratory infections

Finnish researchers found that differences in maternal and infant gut microbiota during the first weeks of life were linked to the risk of respiratory tract infections in the first six months. Specific bacteria, including butyrate producers and opportunistic pathogens, may shape early infection susceptibility.

Red meat consumption disrupts gut bacteria and worsens colonic inflammation

Epidemiological studies have revealed a strong correlation between red meat consumption and the development of inflammatory bowel disease.

Gut microbiota and short chain fatty acids influence bone health in postmenopausal osteoporosis

Postmenopausal osteoporosis (PMOP) is framed as a systemic bone disease driven by estrogen withdrawal, but emerging evidence positions gut dysbiosis and its fermentation products—short-chain fatty acids (SCFAs)—as equally influential regulators of skeletal fate.

Agricultural dust exposure may pose significant risks to gut health

Inhaling agricultural dust may pose significant risks to gut health for workers in animal agriculture, a University of California, Riverside, study has found.

Ionophore use in farming drives global spread of antibiotic resistance genes, study finds

Researchers identified the widespread presence of the ionophore resistance genes narA and narB in over 2,400 bacterial isolates across 51 countries. These genes are often genetically linked to resistance against critically important human antibiotics, raising concerns over agricultural practices and global antimicrobial resistance.

Missing gut bacteria in US babies triples allergy and eczema risk

US infants lacking Bifidobacterium in their gut microbiome face significant changes in microbial composition, metabolic function, and immune-related health risks. This large, nationally representative study links early-life Bifidobacterium deficits to a three-fold increase in eczema, allergy, or asthma by age two.
