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.
