Bacteria (clusters of light pink, surrounded by larger magenta blood cells) can cause deadly infections, but overreactive immune responses can deliver the lethal blow.

An overactive immune response to infection can be deadly. Studying how one key player called tumor necrosis factor, or TNF, induces lethal immune responses could provide new treatment targets.
Only one antiviral medication is approved by the FDA for RSV treatment, and it is administered through a nebulizer.

While RSV can become severe for any child, it poses a particularly serious threat for the youngest babies and for high-risk children.
Neisseria gonorrhoeae bacterium causes gonorrhea by infecting mucous membranes.

The US currently has only one antibiotic available to treat gonorrhea – and it’s becoming less effective.
Bacteria can team up with viruses to cause coinfections.

Coinfections with bacteria can make viral infections even deadlier. Researchers have identified a protein in immune cells that may play a role in fighting both types of pathogens.
With a beam of light, an otoscope allows a clinician to examine the ear canal and eardrum.

With mask-wearing and kids out of school last winter, viral upper respiratory infections decreased. However, clinicians have seen a return of respiratory viruses this summer and ear infections are up too.
With nurse prescribing expanding globally, it’s important they are properly guided and supported when it comes to antibiotics and managing patient expectations.

Observing the progression of an infection in real-time allows us to better understand how antibiotic resistance develops.
Antibiotics do not shorten or reduce the severity of colds or flu, but they could produce adverse effects that make you feel even worse.
Resistant bacteria aren’t the only risk posed by overprescribing antibiotics. A more immediate risk is side-effects and reactions, which a new review shows are surprisingly frequent and often severe.
Methicillin-resistant Staphylococcus aureus (MRSA) bacteria (coloured yellow) enmeshed within a human white blood cell (coloured red). MRSA is a major cause of hospital-associated infections.
Antimicrobial resistance is a public health and economic disaster waiting to happen. If we do not address this threat, by 2050 more people will die from drug-resistant infections than from cancer.

Scientists have developed a new coating for urinary catheters, making them more comfortable and safer to use.
Coronavirus can cause lung damage, pneumonia and multi-organ failure, or sepsis, among other things.
Bacteriophages infecting a bacterial cell.
Bacteriophages are viruses that infect bacteria. But could they be key in solving the antibiotic resistance epidemic?
There’s a short window between when a tick bites and when it passes on bacteria or virus.

Tick-borne diseases are becoming more common in the United States. A public health entomologist outlines some of the lesser-known threats ticks pose to human health.
People typically become sick between one and 21 days after being infected.
The bacteria that causes melioidosis usually lives 30cm underground in clay soil but is dredged to the surface during heavy rains and floods, and can enter the body through small breaks in the skin.
Antibiotics are only useful for treating infections caused by bacteria, not viruses or fungi.
It’s hard to predict how long it will take to feel better after you start taking antibiotics. But if you start feeling worse one to two days after starting the therapy, you must see your doctor.
From a human perspective, some strains are good, some are evil.
E. coli bacteria are the frequent culprits behind outbreaks of food-borne illnesses. But not all strains are harmful; some are even helpful.
Ten cases have been reported so far, including two deaths.

Two people have died after eating rockmelon contaminated with listeria. A total of ten cases have been confirmed in NSW, Queensland and Victoria between Jan 17 and Feb 9, and more are expected.
A giant ant carries a dead fellow in the name of cleanliness.
Ants produce their own antimicrobial chemicals to fight bacteria.
Researchers are using epigenetics to find ways to ‘turn off’ bacteria’s ability to cause infections.
Impetigo happens when itching causes the skin to break and let in disease-causing bacteria.
While school sores – or impetigo – is a treatable condition, if left untreated it can lead to much more serious illness such as kidney and heart disease.
