Unfortunately, the very places we go to receive health care put us at risk for becoming infected with superbugs, bacteria exposed to so many antibiotics that they have become immune to their effects. Clostridium difficile (C. diff) is one such bacteria. It causes inflammation of the colon and rampant diarrhea that can have life-threatening consequences. Part of its virulence lies in the tough spores formed by the bacteria. They are responsible for starting infections in the colon and for spre...
The growing list of dangerous antibiotic resistant organisms has just acquired three new members. Researchers have discovered three new species of Klebsiella bacteria, all of which can cause life-threatening infections and have genes that make them resistant to commonly used antibiotics.
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.
Peach trees and other related plants are susceptible to the devastation caused by fire blight, a contagious bacterial disease. Once contracted, infected trees have to be burned to contain the disease and prevent spread to nearby trees. Increasing resistance to antibiotic treatment has sent scientists in search of alternative ways to deal with the bacteria and prevent its catastrophic damage.
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.
HIV infections persist despite treatment that successfully decreases viral blood levels to the point where doctors can't detect the virus. But that doesn't mean the person is cured. The virus hides in the body, not replicating, just waiting for a chance to jump out of the shadows and reemerge.
Tremendous strides have been made in the treatment and outlook for patients infected with HIV, the human immunodeficiency virus. Treatment with a combination of antiretroviral drugs can keep patients with HIV alive for decades, without symptoms of the infection. The trouble is, if HIV-infected people stop taking their medications, the virus takes over in full force again—because the virus hides out quietly in cells of the immune system, kept in check, but not killed by the treatment.
Hospitals are places we go to get well, and we don't expect to get sick or sicker there. But a study from researchers at the Cleveland Clinic, Case Western Reserve University School of Medicine, and Cleveland VA Medical Center in Ohio found that hospital floors in patient rooms were frequently contaminated with healthcare-associated pathogens—often dangerous multi-drug resistant bacteria.
Antibiotic use in infants has been associated with a host of childhood conditions later in life. Yet when an infection is suspected in a newborn, usually a sample of their blood is drawn to check for the presence of bacteria and 5 to 8 percent of them receive antibiotics while the diagnosis is pending.
This month, Iowa issued their first hepatitis C virus epidemiological profile and the news was not good. The number of cases of hepatitis C reported in Iowa between 2000 and 2015 rose nearly threefold, from 754 cases in 2000 to 2,235 cases in 2015.
We usually associate Salmonella bacteria with a dangerous type of food poisoning, but they actually are pretty good at seeking out tumors. That trait made the bacteria a great candidate to deliver a protein that would help knock tumors out.
Transmitted by a sandfly one-third the size of a mosquito, parasitic Leishmania protozoa are responsible for a flesh-destroying disease that kills an estimated 20,000 people per year. Two new studies offer understanding of how the parasite provides immunity through persistence and why some people suffer more virulent forms of the disease.
