New strategy in the fight against antibiotic resistance

2020-01-14

Bioscience engineers have developed a new antibacterial strategy that weakens bacteria by preventing them from cooperating. Unlike with antibiotics, there is no resistance to this strategy.

New species of antibiotic-resistant bacteria found in infected wound

2020-01-21

A hitherto unknown antibiotic-resistant bacteria species, in the same family as E. coli and Salmonella spp., has been found and classified in Sweden. The proposed taxonomic name of the species -- the first of the new genus -- is Scandinavium goeteborgense, after the city of Gothenburg, Sweden, where the bacterium was isolated and the research was done.

Researchers reverse HIV latency, important scientific step toward cure

2020-01-22

Overcoming HIV latency -- induction of HIV in CD4+ T cells that lay dormant throughout the body - is a major step toward creating a cure for HIV. For the first time, scientists have shown that a new approach can expose latent HIV to attack in two different animal model systems with little or no toxicity.
