“Our findings suggest antibiotics may have a role in colon tumour formation across all age-groups.”

Effects of early-life penicillin exposure on the gut microbiome and frontal cortex and amygdala gene expression
Exposing newborn mice to low-dose penicillin led to substantial changes in intestinal microbiota population structure and composition. Transcriptomic alterations implicate pathways perturbed in neurodevelopmental and neuropsychiatric disorders. There also were […]
Scientists find that common dietary elements cure lethal infections
“Salk Institute researchers report that giving mice dietary iron supplements enabled them to survive a normally lethal bacterial infection and resulted in later generations of those bacteria being less virulent.”
Oral Antibiotic Treatment of Mice Exacerbates the Disease Severity of Multiple Infections
“In summary, we have shown that oral Abx treatment increases the risk of severe disease during flavivirus infection in mice, and we have illuminated a potential role for host microbial […]
Antibiotics may reduce the ability of immune cells to kill bacteria
“A new study led by researchers from the Broad Institute of MIT and Harvard, MIT, and the Wyss Institute for Biologically Inspired Engineering has shown that antibiotics can also reduce […]
Antibiotics taken late in pregnancy can increase risk for IBD in offspring
“A study by researchers at the University of Chicago Medicine shows that when mice that are genetically susceptible to developing inflammatory bowel disease (IBD) were given antibiotics during late pregnancy […]
Antibiotic Use In Young Mice Linked To Inflammatory Disease
“Disrupting the early development of a healthy gut microbiome can do serious — yet reversible — damage, a study finds.”
Antibiotic ‘link to bowel cancer precursor’
“People who take antibiotics for a long time are more likely to develop growths on the bowel which can be a precursor to cancer, a study suggests.”
Low-dose penicillin in early life induces long-term behavioral changes (mouse study)
“low-dose penicillin taken late in pregnancy and in early life of mice offspring, changes behaviour and the balance of microbes in the gut. While these studies have been performed in […]
Excessive antibiotic use in newborns can permanently damage lungs’ defenses
“The study, published Feb. 8 in Science Translational Medicine, shows that short-term disruption of gut bacteria makes infant mice more likely to develop pneumonia. It also makes them more likely […]
