Scientist develops cryo-electron microscopy to clarify salmonellae structure

Bacteria like salmonellae infect their host cells by needle-shaped extensions which they create in large numbers during an attack. A group of Vienna-based scientists headed by Thomas Marlovits employed recently developed methods of cryo-electron microscopy and have been able to clarify the structure of this infection apparatus on the near-atomic scale.

More people sick with salmonella from custard pastries

According to South Australia Health authorities, 13 more people have fallen ill with salmonella that spread via three types of custard-filled pastries made in Adelaide. This brings the total number of ill people to 74 with 29 admitted to hospital with salmonella typhimurium phage type 9 infection. The custard-filled products from Vili’s and St George Cakes and Gelati were recalled after being associated with the salmonella outbreak.

RWV bioreactor creates 3-D cell culture models

The cells and tissues in our bodies grow, develop and interact in a highly complex, three-dimensional world. Likewise, the various microbial pathogens that invade our bodies and cause infectious disease interact with this complex 3-D tissue milieu. In the current issue of the journal Nature Reviews Microbiology, researcher Cheryl Nickerson and her team at the Biodesign Institute at Arizona State University highlight an innovative approach for studying cells in 3-D.

Researchers investigate 'friendly bacteria' to kill bone cancer cells

Children and young people who are diagnosed with bone cancer could benefit from better treatment in the future thanks to new research at The University of Nottingham. The Bone Cancer Research Trust launches Bone Cancer Awareness Week today and has funded a new project at the University which is testing a theory that 'friendly bacteria' can be used to kill bone cancer cells.

Scientists develop humanized mouse model to study typhoid fever

Better treatments and prevention for typhoid fever may emerge from a laboratory model that has just been developed for the disease. The model is based on transplanting human immune stem cells from umbilical cord blood into mice that are susceptible to infections.
