Health & FitDeadly new fungal superbug is worrying doctors — here's what you need to know
Some urinary tract infections are becoming antibiotic-resistant, making them potentially deadly
E. coli bacteria, which is often responsible for causing urinary tract infections, has evolved so it can't be easily killed with antibiotics.
Months after health officials in, and raised concerns about a new deadly fungal superbug, a study has suggested climate change may be playing a role in its troubling rise.
“” (C. auris) is a multi-drug–resistant fungal infection that spreads in hospitals and is extremely deadly — killing as many as who get it, according to the Centers for Disease Control and Prevention (CDC).
Hospitals fight deadly superbug deemed a 'double whammy'
"Doctors asked for a family meeting. It was four or five of us and 13 doctors and that's when we knew it was bad"
While there are likely many reasons that the infection has now spread to, authors of — published this week in the journal mBio — are blaming climate change. The researchers say global warming has played a “pivotal role” in the infection’s rise, citing the fungus’s ability to “grow at higher temperatures.”
"What this study suggests is this is the beginning of fungi adapting to higher temperatures, and we are going to have more and more problems as the century goes on," Arturo Casadevall, MD, PhD, and Molecular Microbiology and Immunology chair at Johns Hopkins Bloomberg School of Public Health. "Global warming will lead to selection of fungal lineages that are more thermally tolerant.”
When to start worrying that a dog bite (or lick) might kill you
If a dog bite breaks the skin, you should see a doctor.
As scientists continue to unpack what’s fueling the rise of this infection, here’s what those who are vulnerable to it need to know.
The infection started in Japan.
was initially discovered in a Japanese man with an ear infection in 2009. It first appeared in the , specifically in a series of patients at a New Jersey hospital. Since then, the CDC has tracked .
Symptoms are difficult to pinpoint.
According to a, the fungus can cause “blood stream infections” and is often spread in hospitals and between nursing home patients. Symptoms are contingent on which part of the body has become infected with the illness, but can include chills and fever. A laboratory test is needed to confirm that it is C. auris that’s present, at which point treatment (often with multiple anti-fungal medications) begins.
Hospital patients and the elderly are most at risk.
Like other drug-resistant infections such as, C. auris poses the most risk to individuals whose immune systems are already compromised — such as those in the hospital, elderly people and those who use breathing tubes. The CDC notes that “healthy people usually don’t get C. auris infections.”
A new species of superbug is emerging—and it loves when you eat sugar
A study "shows how the pathogen C. difficile is evolving in response to the Western sugary diet and common hospital disinfectants."
New York has the highest cases, likely due to travel.
In an email to Yahoo Lifestyle,, chief epidemiologists and associate professor of infectious diseases at NYU Langone Health, says that C. auris is “following the same pattern” as another drug-resistant bacteria, one which started in New York and then spread nationwide. “This is likely due to travel to and from the NYC area,” he says.
It may not technically be a “superbug.”
The Mayo Clinicsuperbugs as “strains of bacteria that are resistant to the majority of antibiotics commonly used today,” but although many have been referring to C. auris as one, Phillips doesn’t necessarily agree. “In spite of the hype, I would not call C auris a superbug,” says Phillips. His reasoning, in part, is that not all C. auris infections are resistant to drugs.
There is no need to panic.
In anfor the Harvard Medical School in May, , noted that while C. auris is a dangerous infection, panic among the general population is not warranted. “Fortunately, Candida auris has not spread to wide swaths of the population, and healthy people rarely develop the infection,” he writes. “When it comes to infectious disease, it’s never time to panic. Instead, you can take constructive steps to deal with concerns about a wide array of infections, even the deadliest ones.” A great way to start, he says, is regularly washing your hands, receiving all your vaccinations and avoiding people who are contagious.

Listeriosis is an food infection caused by the bacterium Listeria monocytogenes. It is a disease that must be declared in France since 1998.
In France, the disease remains rare (incidence of 5 to 6 cases per million inhabitants), but fatal in 30 to 40% of cases occurring in France. outside of pregnancy.
The infectious agent responsible for listeriosis is Listeria monocytogenes . Due to its presence in water, soil and plants, this bacterium has the ability to colonize food manufacturing sites. As a result, it causes foodborne infections and even epidemics.
The foods most frequently contaminated by Listeria monocytogenes are cooked meats (tongue, head, rillettes), waffle products (factories where fish are smoked), chilled sprouts, fresh milk products (cheeses). soft and raw milk dough) and non-annealed catering preparations.
The bacterium is sensitive to heat, but it can still multiply at 4 ° C. Contamination of food is therefore favored by the lengthening of the cold chain (industrial cold stores, household refrigerators).
Moreover, it does not affect the taste of food, unlike most other pathogens transmitted by food.The symptoms of Listeriosis
In the adult , the disease results in an infection of the blood (sepsis), or even the central nervous system, which is then manifested mainly by meningoencephalitis, is to say an infection of the meninges and the brain.
The incubation period ranges from a few days to two months.
In pregnant woman , the infection is usually of no consequence for the mother: it can go unnoticed or take the form of contractions.
On the other hand, the newborn infected has a severe infection, often aggravated by prematurity, which can combine sepsis, pulmonary infection, neurological and sometimes cutaneous. There is effective antibiotic treatment when it is administered quickly. However, the evolution can be fatal even in case of adapted and early treatment.Listeriosis: how to avoid it?
Prevention for people at risk (pregnant women, the elderly, immunocompromised people, etc.) is to avoid the consumption of jelly products, rillettes, pâtés, foie gras, raw milk cheeses, cheeses. soft dough, smoked fish, raw shellfish, surimi, tarama, raw sprouts ...
It is recommended that cook foods of animal origin, remove the rind of all cheeses, wash vegetables carefully and aromatic herbs and to thoroughly anneal the products purchased ready to consume "caterer".
