Researchers discovered that a genetic mutation in Pseudomonas aeruginosa makes it susceptible to destruction by slightly acidified sodium nitrite, a common food preservative. This finding offers new hope for treating cystic fibrosis airway disease.
Researchers have discovered that bacteria share a universal molecular vernacular called AI-2, which enables them to communicate and interfere with each other's behavior. This study shows that AI-2 can be used as a mechanism for one type of bacteria to block another from counting its neighbors and controlling its behavior.
The study found oleanolic acid inhibited the growth of Streptococcus mutans and Porphyromonas gingivalis, two species associated with caries and gum disease. Raisins' phytochemicals may counter a public perception that they promote cavities.
The study found that oleanolic acid and other compounds in raisins inhibited the growth of oral bacteria associated with caries and gum disease. Raisin phytochemicals were effective against Streptococcus mutans and Porphyromonas gingivalis at concentrations ranging from 200 to 1,000 micrograms per milliliter.
Researchers found that higher levels of Actinomyces naeslundii gsp2 in pregnant women's saliva were linked to lower birth weights and preterm deliveries. In contrast, higher levels of Lactobacillus casei during pregnancy positively affected birth weight.
Researchers used high-energy X-ray fluorescence to analyze single living and dead bacterial cells, revealing differences in morphology, elemental composition, and sensitivity to heavy-metal contaminants. The study pioneers a technique for investigating microbiological systems in natural subsurface environments.
Scientists at UC Riverside have modified an existing full-scale chemical scrubber to a biological trickling filter, achieving treatment rates comparable to chemical scrubbers. The conversion resulted in annual savings of $30,000 per year, with potential for widespread adoption and significant cost benefits.
The partnership aims to advance biomedical research through collaboration between biologists and mathematicians/scientists. The new awards will support projects in areas such as disease modeling, HIV dynamics, and bioinformatics.
Certain strains of E. coli produce amyloid fibers similar to those found in Alzheimer's disease, forming a meshwork around the bacteria in biofilms. This discovery raises questions about the role of bacterial infections in amyloid diseases, including Alzheimer's, and may lead to new treatment options.
Researchers created high-resolution pseudo-images of minerals within basalt and bacterial growth, providing critical information about bacterial metabolism. The technique also creates three-dimensional images, allowing researchers to understand the complex relationships between microbes, minerals, and contaminants.
Researchers have discovered a potent anti-cavity agent in Brazilian honeybees' propolis, which cut the cavity rate in rats by about 60 percent. The team is now testing the substance on human volunteers to determine its efficacy as a potential preventative measure for cavities.
