A new study reveals that changes in the gut microbiota occur early in diabetes development, with beneficial bacteria more prevalent in those maintaining stable blood sugar control. The research suggests a link between gut bacteria and metabolic health, potentially informing strategies to prevent or manage Type 2 diabetes.
Researchers from Loyola University Chicago found bacteria in the bladders of healthy women, challenging the common belief that normal urine is sterile. The study also revealed differences in bladder bacteria between healthy women and those with overactive bladder (OAB), which may contribute to OAB symptoms.
Bacterial community composition at two beaches shows distinct differences but also similarities, suggesting regional human impact variations. Higher bacterial diversity at one site indicates better ecological health and resiliency to sewage contamination.
A new model from Uppsala University predicts how bacteria can rapidly adapt to environmental changes through smart regulation of gene expression. The study shows the ultimate limit for bacterial protein level adjustments in response to changing environments.
A new study reveals triclosan is fueling the development of resistant bacteria in streams and rivers, disrupting native bacterial communities and potentially diminishing the usefulness of important antibiotics. Urban sites are most impacted by high levels of triclosan pollution from combined sewer overflows.
A recent study published in Nature found that approximately 1 in 4 individuals have fewer than average intestinal bacteria, leading to reduced diversity and increased inflammation. This lack of gut bacteria is associated with a higher risk of obesity, type 2 diabetes, and cardiovascular diseases.
A new study published in BMC Microbiology reveals that children with eczema have a more diverse set of bacteria in their guts than healthy children. The types of bacteria present were also more typical of adult gut microbes, suggesting an early change towards adult-type bacteria may be a risk factor for eczema.
Scientists have discovered a new antibiotic principle that selectively blocks the thioredoxin system in bacterial cells, making certain bacteria vulnerable to inhibition. This mechanism could potentially treat conditions like stomach ulcers, TB, and MRSA, providing a new solution for combating antibiotic-resistant infections.
A Norwegian study found that triclosan exposure in children is associated with elevated IgE levels and rhinitis. Triclosan has been linked to an increased risk of developing allergies due to its ability to change bacterial flora on the skin, in the mouth, and in the intestines.
A study by University of Illinois researchers found that the gut microbiome composition of growing kittens differs depending on their diet, with high-protein diets linked to lower levels of health-promoting bacteria. Conversely, moderate-protein diets were associated with higher levels of beneficial bacteria, potentially promoting bett...
A study published in Nature reveals that people with type 2 diabetes have a high level of pathogens in their intestines, which can increase resistance to certain medicines. The research also identifies biological indicators that could be used for faster and earlier diagnosis of the disease.
A study by University of Minnesota researchers found that antimicrobial growth promoters in swine alter intestinal bacteria composition, leading to accelerated growth and development. The findings suggest a possible alternative to antibiotics in animal production without compromising animal health.
Researchers identified four types of bacterial communities in healthy adults at 10 sites along the digestive tract. They found a core set of metabolic genes present throughout, suggesting common functions needed for bacterial communities living on mucosal surfaces.
Research finds that caesarean section delivery may double the risk of subsequent childhood obesity, with higher levels of Firmicutes bacteria and lower Bacteroides bacteria in the guts of children born via c-section. This association is thought to influence energy extraction from diets, insulin resistance, inflammation, and fat deposits.
A study suggests that eating pistachios can increase beneficial bacteria in the gut, potentially supporting digestive health. Researchers found a stronger effect on gut microbiota composition in those who ate pistachios compared to almonds.
Researchers at Loyola University Chicago Stritch School of Medicine found bacteria in the bladders of some healthy women, challenging the common belief that normal urine is sterile. The study also revealed that standard urine collection methods can be contaminated by vaginal bacteria.
