Infections

One type of parasite, Entamoeba histolytica, has developed a very intriguing way to evade the defences of our immune system. It rips pieces off human cells and steals the proteins to wear them as a disguise.

The world's largest study into the long-term health impact of floods has found that there are surges in hospitalizations for months after an event – and current responses are inadequate when it comes to treating cancer, diabetes, mental health and more.

Looking beyond jabs, sprays or tablets, scientists are thinking outside the box for delivering antiviral medication to prevent the spread of highly transmissible bugs. Their secret weapon? Chewing gum – but one made from a rather fascinating bean.

A three-year study has found robust evidence that one vaccine for respiratory syncytial virus offers older adults long-term protection, even if efficacy wanes. Despite this, just one dose cut serious illness by nearly two thirds across three seasons.

A decade-long study of 35 million Americans in 10 states has found that group A streptococcus infections have more than doubled. What's more, "strep" – which can cause a bizarre flesh-eating disease – has become increasingly resistant to antibiotics.

It's never a good thing, when a bacterial biofilm forms on the surface of a medical implant. There could soon be a new way of eradicating such films, however, using tiny remote-control liquid-bodied robots.

Scientists have made a major breakthrough in the accuracy and speed at which serious and often deadly pathogen infections can be diagnosed and treated. Often, this is time that is critically important in saving a patient's life.

A new zombie pathogen has been discovered in Ireland. This insidious fungus infects cave spiders and alters their behavior to help spread its spores to new victims.

HIV has become a more manageable condition in recent years, but a full cure remains elusive. Now, scientists have found promise in permanently eliminating the virus, thanks to a drug already approved by the FDA to fight cancer.

A coughing, sneezing, 3D-printed model of the human nose and upper airway has provided researchers with a better understanding of how airborne infections are transmitted. The knowledge will aid in developing effective ways of reducing that spread.

The US has recorded its first death due to avian influenza. The man had been infected by a H5N1 variant with a genetic mutation, helping it target upper respiratory tract receptors – one also seen in the Canadian teen who fell critically ill last year.

If you were given a choice of vaccine delivery method, would you rather a needle or a skin cream? Thought so. Well, the latter might be a viable option soon, as Stanford scientists have used a topical cream to strongly vaccinate mice against tetanus.
