News: Florida & Texas Could Become Zika Hotspots in the US

To much of the United States, Zika seems like a tropical disease that causes horrible problems in other countries but is nothing to be worried about stateside. It may make you rethink your beach vacation abroad, but not much more than that. However, if you live in Florida or Texas, the possibility of getting a Zika infection where you live is real — and local outbreaks are more and more a possibility.

News: This Genetic Defect Could Be Why Typhoid Mary Never Got Typhoid Fever

Whether or not a microbe is successful at establishing an infection depends both on the microbe and the host. Scientists from Duke found that a single DNA change can allow Salmonella typhi, the bacteria that causes typhoid fever, to invade cells. That single genetic variation increased the amount of cholesterol on cell membranes that Salmonella and other bacteria use as a docking station to attach to a cell to invade it. They also found that common cholesterol-lowering drugs protected zebrafi...

News: How Calcium Sets Off a C Diff Infection

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...

News: Hospital Floors May Look Clean, but They're Teeming with Deadly Superbugs—Including MRSA, VRE & C. Diff

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.

News: Researchers Look to Cows to Create Vaccine for HIV

A vaccine against HIV might prevent the disease that we can't seem to cure. Some HIV patients make antibodies that can take down the virus, much the way a vaccine might. But, scientists haven't been able to provoke that type of response in other people. However, in a process that might work in humans, a group of researchers has successfully generated antibodies in cows that neutralize multiple strains of HIV.

News: Powassan Virus Implicated in Recent NY State Death

A recent case of Powassan virus has been reported in Saratoga County and may have been the cause of the infected patient's death. It's the 24th case in New York State since 2000, and will be reported to the CDC tomorrow, the NY Department of Health told Invisiverse. The tick-borne illness has no vaccine or specific treatments and can damage the nervous system.
