Twelve-year old Rory Staunton took a dive for a basketball during gym class and came up with a cut on his arm. The school nurse applied a couple of band-aids, without cleaning the cut, and off he went. In approximately three days, hospital physicians told his parents there was nothing else that they could do for their son; he was dead.
With a death rate of one in five, sepsis is a fast-moving medical nightmare. New testing methods might improve your odds of survival if this infection ever hits you.
Lyme is a growing threat as we move into warmer weather in the US. Researchers have said this year could be one of the worst for this tick-borne disease, as a skyrocketing mouse population and warmer temperatures increase the risk.
As if being pregnant did not come with enough worry, a new study found that certain antibiotics are linked to an increased risk of spontaneous abortion, or miscarriage — a terrifying finding for any expectant mother.
Being infected with HIV means a lifetime of antiviral therapy. We can control the infection with those drugs, but we haven't been able to cure people by ridding the body completely of the virus. But thanks to a new study published in Molecular Therapy by scientists at the Lewis Katz School of Medicine (LKSOM) at Temple University and the University of Pittsburgh, all that may change.
When just floating peacefully in the water with their brood mates, the Culex mosquito larvae in the image above does not look very frightening. But in their adult form, they are the prime vector for spreading West Nile virus — a sometimes mild, sometimes fatal disease.
Viral infections have been the focus of attention in the development of autoimmune diseases—diseases where the body's immune system reacts to the body's own cells—because they trigger the immune system into action.
A new study confirms that antibiotics can prevent surgical intervention if your child's appendix becomes inflamed, potentially saving his or her life.
We may not fully appreciate all the important roles wheat plays in our lives until it's gone—or at least, when it's in very short supply. What would a world be like without bread, cakes, cereal, pasta, or wheat beer? If the dire warnings about an impending stem rust fungus come to pass, we may know all too soon.
Every year, 100-200 people in the US contract leptospirosis, but usually 50% of the cases occur in Hawaii where outdoor adventurers are exposed to Leptospira bacteria found in freshwater ponds, waterfalls, streams, and mud. That's why it's so alarming that two people in the Bronx have been diagnosed with the disease and a 30-year-old man has died from it.
After California college student Luis Ortiz blacked out and was taken to the hospital in 2015, doctors were startled to discover the reason his brain was swelling—a one-centimeter long, wriggling tapeworm living within a ventricle in the middle of his brain.
A new study shows the Zika virus is present in saliva — but it may not be enough to make you sick. The Centers for Disease Control and Prevention notes there is "no evidence that Zika can be transmitted through saliva during deep kissing." Given the results of research published in the journal, Nature Communications," the agency may need to revise its guidance.
The Centers for Disease Control and Prevention estimated that there were 212 million cases of malaria across the world in 2015, and 429,000 of those people died — mostly children living in Africa. Preventing and treating those infections has been a challenging world priority. That makes a new malaria drug discovery — published in Science Translational Medicine — incredibly important.
It's not the bacteria itself that takes lives and limbs during invasive flesh-eating bacteria infections. It's the toxins secreted by the group A Streptococcus bacteria invading the body that causes the most damage.
Usually, we think of vaccines as preventative, a shot we get to prevent the flu or some childhood disease like measles or mumps. But there are vaccines for other purposes, such as the ones studied by researchers from the Netherlands.
How can bacteria that lives in the throat of 10%–35% of people—without causing an infection—cause life-threatening meningitis and sepsis in others?
Norovirus outbreaks occur all year long, but peak in the winter months, which means we are in the middle of norovirus season. But there's still time to protect yourself from the highly infectious bug.
Sometimes, it helps to be prepared before jumping into a new relationship; look before you leap! To have a healthy relationship with someone who has an STI, it is advisable that you enter the relationship knowledgeable about sexually transmitted infections and what your risks might be.
Andre was enjoying the carefree life of a 12-year-old with his friends, riding his bike and playing sports, like all kids that age. Schoolwork wasn't hard for him, and his grades showed that.
Primarily caused by the bacteria Borrelia burgdorferi, Lyme disease is the most common tickborne disease in the US. By all predictions, 2017 is expected to be a banner tick year in several regions. If you have children, it is important to know what to expect.
Sepsis is not only a gross sounding word but also a deceptively dangerous and fatal infection. Which is why more than 40 hospitals nationwide are coming together to a new collaboration to help reduce sepsis mortality, named Improving Pediatric Sepsis Outcomes (IPSO).
Over the past eight months, ten infants at UC Irvine Medical Center tested positive for the same strand of methicillin-resistant Staphylococcus aureus (MRSA). Despite the danger of this superbug due to its high resistance to most antibiotics, this information was only released to the public on Thursday. Thankfully, all ten babies survived and are currently healthy.
Urinary tract infections (UTIs) drive over eight million people to seek medical attention every year. Almost all — as many as 90% — of those infections are caused by Escherichia coli. Copper can kill bacteria, but E. coli has found a way to capture the copper, preventing its antibacterial action. Now, researchers have found that, in a cruel irony, the bacteria use the copper it grabs as a nutrient to feed its growth.
How can a drug used to treat cancer be effective against viruses, too? The answer lies in the drug's shared target — specifically, cellular components that control the activity of genes. A new research study showed that one such type of drug, histone methyltransferase inhibitors used in cancer clinical trials, has activity against herpes simplex virus, too.
For younger children, a day at the playground is not complete without some sandbox time. Long a favorite of children and parents, sandboxes could also be sheltering dangerous pathogens.
It's not always easy to get to the root of an infection outbreak. Epidemiologists study infected people, contacts, and carefully examine where the infections happened and when. In the case of a 2012 outbreak of pertussis — whooping cough — in Oregon, scientists just published an analysis of how vaccination status affected when a child became infected during the outbreak.
Phase 2 of a Zika vaccine trial began in the United States this week, along with Central and South America.
An outbreak of anthrax from contaminated meat in Tanzania sickened dozens of people and moves the danger of this deadly bacteria back into focus.
Cholera is rapidly spreading in Mozambique, with over 1,200 people infected. Since the outset of 2017, cholera has spread from the capital city of Maputo (pictured above) to three of its ten provinces. Health officials report other areas in the country are seeing case counts rise, and two deaths have been logged so far.
Somewhere around 600–800 million people in the world are infected with whipworm (Trichuris trichiura), an infection they got from ingesting soil or water contaminated with feces of infected animals or people containing the parasite's eggs.
New research suggests the bacteria that causes listeriosis may be a bigger threat in early pregnancy than previously thought. Usually considered a danger to late pregnancy, scientists suggest early undiagnosed miscarriages could be caused, in some cases, by infection with Listeria.
You know the signs—sneezing, fever, nagging cough, no energy, no appetite. It's the flu, but this time, it's your dog who's down and out. Yes, dogs get the flu, too. However, a team from the University of Rochester Medical Center and their collaborators have developed a new vaccine that may make the doggy flu a thing of the past.
The story of Helicobacter pylori is a real testament to the tenacity of medical researchers to prove their hypothesis. It took decades before the scientific world would accept that the bacteria H. pylori caused ulcers.
Phuket, the island in Thailand typically associated with paradise and most recently, illegally-run hotels, now has a different problem—a stray cat with the claws of death.
For the first time, the US Food and Drug Administration (FDA) has approved medication to treat children with a serious infection called Chagas disease, which stealthily infects and damages the hearts of millions of victims a year.
Gonorrhea infections reached a peak in 1975, then decreased until 2009, when infection rate started rising and has increased each year since. With the rise of antibiotic resistance, those numbers are only going to get worse — unless we find new treatments against the bacteria.
A promising new antibiotic has been discovered in, of all things, another bacteria. Burkholderia bacteria live in diverse habitats, including soil, plants, and humans where they thrive by knocking out other microbes that compete with them for resources or threaten their existence. Scientists have discovered they accomplish this by producing a very effective antibiotic.
The body's usual response to a bacterial infection in the blood — called sepsis — takes time. It requires a carefully orchestrated sequence of events that gets the body's immune system ramped up to deal with the invading bacteria.
Usually, the mucus lining of the female genital tract presents a barrier that helps prevent infections. But, somehow, the bacteria that causes gonorrhea gets around and through that barrier to invade the female genital tract.
