Extremely premature infants who fail to grow as expected have delayed development of their microbiome, or communities of bacteria and other micro-organisms living in the gut, according to a new study published in Scientific Reports.
A new study by Tel Aviv University researchers finds potent antibacterial capabilities in novel dental restoratives, or filling materials.
A new study conducted by researchers in Leicester and Nottingham has shown the potential for a new blood test to not only diagnose human tuberculosis (TB) but also identify those at most risk of developing the disease, according to findings published in medical journal Clinical Infectious Diseases.
Prof. Brice Felden and his team at the Inserm and Université de Rennes 1 'Bacterial Regulatory RNAs and Medicine' joint laboratory (U1230) has developed two new antibiotics that do not trigger resistance when they are used to treat infection in mice. This French advance could bring both fresh impetus and new possibilities for fighting antibiotic resistance worldwide.
By combining two well-established antibiotics for the first time, a scientific team led by Case Western Reserve University School of Medicine and Louis Stokes Cleveland VA Medical Center has delivered a 'double whammy' against the pervasive Pseudomonas aeruginosa, a potentially deadly form of bacteria that is a major source of hospital-based infections.
Ulvan is the principal component of Ulva or 'sea lettuce' which causes algal blooms (green tides). Frenc sientists and their German and Austrian colleagues have identified a marine bacterium whose enzymatic system can break down ulvan into an energy source or molecules of interest for use by the agrifood or cosmetics industries. Twelve enzymes have thus been discovered and they constitute as many tools that could transform this under-exploited polysaccharide into a renewable resource.
Scientists at UPF and the company S-Biomedic have demonstrated the use of living bacteria to modulate skin microbiome composition. In the study, published in Microbiome, mixtures of different skin microbial components have been used to temporarily modulate the composition of recipient skin bacteria for therapeutic or cosmetic purposes.
Bacteria of the Acinetobacter ACB complex, which are frequently acquired in hospital settings, can also be found in beef meat, according to a study led by ISGlobal, an institution supported by 'la Caixa' and performed with meat samples from markets in Lima, Peru. Although the isolates were susceptible to most antibiotics, these results suggest that raw meat can act as a reservoir for these pathogenic bacteria.
Research by scientists into why some bacteria have different shapes has found that a curved shape can make it easier to find food. Computer simulations were used to compare the swimming of differently shaped bacteria. Results showed that a curved shape can be beneficial for efficient swimming and for finding food through the use of chemical trails (known as chemotaxis) - but at the expense of higher cell construction costs.
Scientists at the University of Birmingham have shed fresh light on the mechanism used by certain types of bacteria to protect themselves against attack.
