Recent studies on tuberculosis have yielded conflicting results, leaving questions about the role of the lung microbiome in the disease. The variability in study methods, particularly in sampling techniques, may be a major contributor to these discrepancies.
The study found a small number of species associated with periodontitis, but not gingivitis, including Prevotella, Treponema, and Selemonas. This research may lead to an inexpensive and rapid point-of-care test based on distinguishing the two conditions' microbiomes.
Researchers found that infants' airways are colonized with bacteria or bacterial DNA at birth, which could predict severe lung disease. The 'healthy' pattern of colonization seen in BPD-resistant infants is protective, with increased abundance of Lactobacillus.
A cervical stitch used to prevent preterm labor has been linked to a three times higher risk of stillbirth and almost twice the risk of preterm birth. The suture may disrupt the vaginal microbiome and spur inflammation, major risk factors for preterm birth.
A new study suggests that dispensary-grade cannabis may contain harmful yeasts and toxic molds, compromising its medicinal benefits. The researchers recommend re-evaluating culture-based techniques and conducting additional sequencing-based studies to investigate the cannabis microbiome.
A study found that contact lenses alter the natural microbial community of the eyes, making it more skin-like. This shift in bacterial composition increases the risk of eye infections such as giant papillary conjunctivitis and keratitis.
A study found that Canadian First Nations children with severe early childhood caries had a distinct oral microbiome, with higher levels of cariogenic microorganisms and population shifts in their oral microbial communities. This may explain the high prevalence of S-ECC in Indigenous children.
Scientists cultivate over half of the bacterial species found on and in the leaves and roots of Arabidopsis thaliana, creating a representative collection for microbiota reconstruction. The developed toolkit enables controlled perturbation of microbiota under controlled environmental conditions.
A study by George Washington University researchers has identified a unique microbiome pattern in the throat of individuals with schizophrenia. The findings suggest that certain oral bacteria may be associated with the disease, offering new possibilities for diagnosis and treatment.
Recent studies have shown that thinking of plants and animals as autonomous individuals is a serious over-simplification. Microbiologists propose the concept of holobionts, which consists of visible hosts plus millions of invisible microbes that significantly affect development, diseases, behavior, and social interactions.
Researchers discovered that phytohormones regulate microbial abundance, influencing the composition of root microbiomes. The study found that plants can select and benefit from specific strains of microbes, but also face pathogens that take nutrients and damage plants.
Researchers discovered that a plant hormone, salicylic acid, acts as a 'bacterial bouncer' below ground, sculpting the microbiome surrounding a plant's roots. This finding suggests that salicylic acid is required to assemble a normal, commensal root microbiome.
Breakthroughs in HCV therapy suggest increased cure rates, including for patients with cirrhosis. Fecal microbiota transplantation shows promise in treating C. difficile, while drug-induced liver injury warnings are also emphasized.
Researchers create genetic profile of grape crown gall tumor disease, identifying core microbiome common to 52 sampled tumors. The study aims to improve disease management and crop production of all grape varieties.
Research reveals maternal obesity alters offspring microflora composition, increasing firmicutes to bacteriodetes ratio and gastrointestinal permeability. This non-genetic factor may contribute to increased susceptibility to obesity and associated metabolic disorders.
New research suggests that mango consumption may reduce inflammation in ulcerative colitis and promote bone health in ovariectomized mice. Mango polyphenolics also showed potential in modifying microbiota and short chain fatty acid production in rats with DSS-induced colitis.
The root microbiome plays a vital role in plant functions and ecosystem well-being, influencing genetic structure, health, and interactions with other plants. Microbial organisms associated with plant roots have far-flung global influences, from regulating plant performance to facilitating crop production in harsh climates.
A new study provides direct evidence that microbes can contribute to the origin of new species by reducing the viability of hybrids. The researchers used jewel wasp species with similar microbiomes but differing genetic backgrounds to demonstrate this effect.
Researchers found that certain bacteria in the stomach microflora can change the response to Helicobacter pylori infection, potentially allowing for prediction of disease development and identification of potential probiotics. The study, published in Infection and Immunity, has implications for treating human infections.
Researchers will analyze water chemistry and pipe materials under controlled conditions to determine the effects of pipe material, water flow, and chemistry on building plumbing microbiomes. The study aims to improve public health by identifying factors that control microbe growth in water systems.
A recent study sheds light on the mechanisms driving the formation of the 'plant microbiome' and how plants influence microbial communities. Researchers identified key microbial players and their metabolic roles, revealing a complex interdependence between host plants and soil microbes.
A new NIST report summarizes efforts to advance indoor microbial sampling, highlighting challenges and future priorities for surface and aerosol analysis. The report explores cross-cutting issues such as education and public awareness, and provides a comprehensive overview of existing resources.
Researchers aim to optimize women's health by examining bacterial balance in the vagina. The Vaginal Microbiome Project will develop diagnostic tests to prevent preterm birth, a major consequence of abnormal bacterial balance.
The study developed a molecular marker for Pi-deficiency in rats and evaluated the efficacy of Chinese materia medicas and probiotics. It found that middle doses of these recipes showed pronounced recovery activities, while higher doses did not.
Researchers found that certain populations of bacteria in contaminated coastal waters can degrade crude oil components, particularly polycyclic aromatic compounds. This discovery suggests that indigenous microbiota have evolved to handle the pollution, paving the way for potential bioremediation methods.
Research suggests that changes in gut microflora can intensify immune reactions to common allergens, increasing the risk of chronic allergies or asthma. A mouse model study found that antibiotic treatment led to an overzealous allergic response in the lung.
