Deadly Bird Flu Virus Takes Hold in Humans, Study

New research has taken a step towards understanding how highly pathogenic influenza viruses such as deadly bird flu infect humans. Researchers at Griffith's Institute for Glycomics and the University of Hong Kong have shown specific sugar molecules-S-glycans-that are present in the respiratory tract  are key receptors for  influenza viruses, particularly the highly pathogenic influenza virus strains

Bacterial Evolution: Dodging Antibiotic Resistance by Curbing It

Lowering mutation rates in harmful bacteria might be an as yet untried way to hinder the emergence of antimicrobial pathogens. One target for drug development might be a protein factor, DNA translocase Mfd, which enables bacteria to evolve rapidly by promoting mutations in many different bacterial species.

This action speeds antibiotic resistance, including multi-drug resistance. Working on drugs to block Mfd and similar factors could be a revolutionary strategy to address the worldwide crisis of treatment-resistant infectious diseases.

Insect Antibiotic Targets Gram-negative Bacteria, Study

An antibiotic called thanatin attacks the way the outer membrane of Gram-negative bacteria is built. Researchers at the University of Zurich have now found out that this happens through a previously unknown mechanism. Thanatin, produced naturally by the spined soldier bug, can be used to develop new classes of antibiotics.

Multiple Triggers for Kawasaki Disease

Researchers have evidence that Kawasaki Disease (KD) does not have a single cause. By studying weather patterns and geographic distributions of patients in San Diego, the research team determined that this disease has influenced multiple environmental triggers by a combination of temperature, precipitation and wind patterns.

EPA Approves for New Bacteriostatic Surface Coating

Allied BioScience, a Plano, Texas-based biotechnology company announced today it has received an approved label from the US Environmental Protection Agency (EPA) for SurfaceWise ™, a new bacteriostatic surface coating that inhibits the growth of and provides continuous protection against bacteria, fungi (mold and mildew) and algae which cause odor, staining and discoloration in various commercial settings, including hospitals and sports facilities.

Invasive Property of Breast Cancer Cells Identified

Researchers from Karolinska Institutet in Sweden have identified a protein that determines the identity and invasive properties of breast cancer cells. The finding could lead to the development of new therapeutic and diagnostic strategies to target breast cancer invasion and metastasis. The study is published in the scientific journal Cancer Research.
