NewsDischarge of untreated hospital effluent is a key driver of multidrug resistance, study finds
A new study has highlighted the discharge of untreated hospital effluent to the environment as a major driver of multidrug resistance among the microbial community.

NewsHibernation status matters when white-nose syndrome pathogen infects bats
The fungal pathogen that causes white-nose syndrome (WNS) in bats uses different cell entry strategies depending on the host’s hibernation status – cold and inactive, or warm and active.

NewsRespiratory bacteria ‘turns off’ immune system to survive
Researchers have identified how a common bacterium is able to manipulate the human immune system during respiratory infections and cause persistent illness.

NewsDensely packed E.coli bacteria form immobile material similar to colloidal glass
Dense E.coli bacteria have several similar qualities to colloidal glass. When they become higher in density and more packed together, they form a ’glassy state’ but also show some other unique properties not typically found in glass-state materials.

NewsPumpkin disease not evolving - which could make a difference for management
The bacterium, Xanthomonas cucurbitae, is so successful that it has had no reason to evolve through time or space, according to new research characterizing the pathogen’s genetic diversity across the Midwest.

NewsMayaro and chikungunya viruses observed circulating at the same time in the Brazilian Amazon
Infection by one virus was expected to afford protection against the other, preventing co-circulation. Researchers are warning of the risk of transmission of Mayaro in urban areas due to deforestation and advocate more effective epidemiological surveillance.

NewsReinfections from the virus that causes COVID-19 likely have similar severity to original infection
Researchers have found that severe infections from the virus that causes COVID-19 tend to foreshadow similar severity of infection the next time a person contracts the disease.

NewsNanoparticle vaccines enhance cross-protection against influenza viruses
To offer cross-protection against diverse influenza virus variants, nanoparticle vaccines can produce pivotal cellular and mucosal immune responses that enhance vaccine efficacy and broaden protection, a new study reveals.

NewsThe plague may have caused the downfall of the Stone Age farmers
Ancient DNA from bones and teeth hints at a role of the plague in Stone Age population collapse. Contrary to previous beliefs, the plague may have diminished Europe’s populations long before the major plague outbreaks of the Middle Ages.

NewsMagnetic bacteria could be key to the miraculous mystery of migration
The remarkable ability of migratory animals to navigate and recall routes may be attributed to a sensitivity to not just Earth’s magnetic fields, but perhaps an interaction with magnetic bacteria living inside them, a new study suggests.
