The 12 most dangerous superbugs, ranked by the WHO

 

The World Health Organization says we need to step up the fight against a dozen bacteria that are growing resistant to all the antibiotics we have to treat them.

One of the scariest features of the antibiotic resistance crisis — which has been accelerated by how we overuse these drugs — is that pharmaceutical companies aren’t developing new antibiotics quickly enough. They also often place profits ahead public health when choosing which drugs to develop.

Bees ‘Self-Medicate’ when infected with some pathogens

bees 34567

When faced with pathogenic fungi, bees line their hives with more propolis – the waxy, yellow substance seen here.

Research from North Carolina State University shows that honey bees “self-medicate” when their colony is infected with a harmful fungus, bringing in increased amounts of antifungal plant resins to ward off the pathogen…

‘Plastic antibodies’ developed halts spread of deadly bee venom in mice.

In a breakthrough study, researchers at UC Irvine have developed the first “plastic antibodies” and successfully introduced them into the blood of mice to halt the spread of deadly bee venom.

A new study led by Indian-origin researcher has revealed that edible apple film wraps can protect meat and poultry products from food borne pathogens.  Researchers from the University of Arizona used arvacrol and cinnamaldehyde in apple-based films, which showed promise in offering protection against Salmonella enterica, Escherichia coli O157:H7 and Listeria monocytogenes.

Food ‘tattoos’ – an alternative to labeling fruit.

Those small and sometimes inconvenient sticky labels on produce may eventually be replaced by laser “tattoo” technology now being tested by Agricultural Research Service (ARS) and University of Florida scientists.

Pet Owners At Increased Risk Of Acquiring Fatal MRSA Infection

Pet Owners At Increased Risk Of Acquiring Fatal MRSA Infection

Pet bites can cause potentially fatal MRSA infection 

Pet owners are at an increased risk of getting infected with the potentially fatal MRSA infection through dogs and cats, say researchers.

Dr. Richard Oehler, of the University of South Florida, says that MRSA and skin infections in dogs and cats can be spread to humans through bites.

Study Of Spit To Learn How Germs Spread

Study Of Spit To Learn How Germs Spread

Girl sneezing 

Mark Nicas has given some of his best years to spittle. He builds models – the mathematical kind – of how someone else’s slobber ends up on you. The size of the particles, whether they come out in a dry cough or a wet sneeze, their evaporation rate, air speed – these are all complications, reasons why people like Nicas can spend careers piling up academic papers, all the while building up a healthy respect for pathogens.

Instant Immunity From A Vaccine

Instant Immunity From A Vaccine

 

A new approach primes antibodies to instantly attack cancers, HIV, and other diseases.

The body’s immune system is often likened to an army, and vaccines to training exercises that build up defenses against pathogens. By exposing the immune system to inactive forms of a virus or bacteria, a vaccine trains antibodies to fight off a real pathogen in the event of an invasion. However, while vaccines prepare antibodies to identify an attacker, they often don’t give specific instructions on exactly how to bring it down. Some antibodies may successfully hit a pathogen’s weak spot, while others may miss the mark entirely. That’s part of the reason why it normally takes several weeks or months for some vaccines to build up an effective immune response.
