NewsStudy highlights factors associated with higher tuberculosis risk in South Africa
Tuberculosis is the world’s top infectious killer. About 10 million people fall ill with the disease every year, and roughly 1.5 million people die because of it, according to the World Health Organization. Additionally, about one-quarter of the world’s population is infected with the disease’s causative agent Myctuberobacterium tuberculosis. ...

NewsCoinfecting viruses impede each other’s ability to enter cells
Scientists researching phage infection at the level of a single cell investigated whether the number of infecting phages that bind to the bacterial surface corresponds to the amount of viral genetic material that is injected into the cell.

NewsNovel nanosensing technique offers quality control of viral vectors in gene therapy
Researchers report a novel nanosensing technique to measure viral vector characteristics, measuring the ionic current that flows through a nanopore opening when a voltage differential is applied to a solution containing adeno-associated virus.

NewsBiocides are a useful tool to combat antibiotic resistance but appropriate use is vital, scientists suggest
A recent review in Sustainable Microbiology discusses how the use of biocides can promote well-being but must only be used when there are clear benefits.

NewsClimate anomalies may play a major role in driving cholera pandemics
New research suggests that an El Niño event may have aided the establishment of a novel cholera strain during an early 20th-century pandemic, suggesting climate anomalies could create opportunities for the emergence of new cholera strains.

NewsWarming stops tiny organisms working together
The single-celled organism Paramecium bursaria can absorb and host algae (Chlorella spp), providing benefits for both, but when scientists made the water 5°C warmer, the partnership stopped working – and the algae may even become parasitic.

NewsShared geographic origin of TB strain and human host could boost risk of infection
For some forms of tuberculosis, the chances that an exposed person will get infected depend on whether the individual and the bacteria share a hometown, according to a study comparing how different strains move through mixed populations in cities.

NewsSuper cally molecules take down tuberculosis
Researchers have identified and synthesised a group of molecules that can act against the cause of tuberculosis in a new way. The callyaerins act against TB by employing a fundamentally different mechanism compared to antibiotic agents used to date.
