Study finds state policies influence vaccination, disease outbreak rates

Athens, Ga. - Lax state vaccination laws contribute to lower immunization rates and increased outbreaks of preventable diseases--like whooping cough and measles--according to a new study from the University of Georgia. Read More

ZIKA VIRUS ‘IS ABOUT AS SCARY AS IT GETS’

The Zika virus, unlike other mosquito-borne viruses such as dengue, has until now been relatively unknown and unstudied. Read More

How long have primates been infected with viruses related to HIV?

Disease-causing viruses engage their hosts in ongoing arms races: positive selection for antiviral genes increases host fitness and survival, and viruses in turn select for mutations that counteract the antiviral host factors. Studying such adaptive mutations can provide insights into the distan... Read More

8th grader petri dishes - seeking help to identify colonies

I did a study of hand washing and hand sanitizer. Is anyone on the list willing to help me identify what grew from my unwashed and even washed hands? I attach three photos representing the yellow, white and orange growths found after several days on agar plates. Thank you so much in advance. Read More

Chestnut leaves yield extract that disarms deadly staph bacteria

Leaves of the European chestnut tree contain ingredients with the power to disarm dangerous staph bacteria without boosting its drug resistance, scientists have found. Read More

Interrupting the transmission cycle: A protein required for dengue virus infection of mosquitoes

There is currently no approved specific treatment or vaccine for dengue fever, and an estimated 2 billion people are at risk for being bitten by Aedes mosquitoes and infected with the dengue virus (DENV). A study published on October 22nd in PLOS Pathogens introduces a candidate target for a tra... Read More

Molecular 'kiss of death' flags pathogens

DURHAM, N.C. -- Many bugs that make us sick -- bacteria, viruses, fungi and parasites -- hide out in our cells in protective little bubbles called vacuoles. To clear an infection, the immune system must recognize and destroy these vacuoles while leaving the rest of the living cell intact. Read More

NIH-funded study establishes genomic data set on Lassa virus

An international team of researchers has developed the largest genomic data set in the world on Lassa virus (LASV). The new genomic catalog contains nearly 200 viral genomes collected from patient samples in Sierra Leone and Nigeria, as well as field samples from the major animal reservoir, or h... Read More

Role of breast cell infection in flu transmission between mothers and breast-feeding ferrets

Influenza is known as an infectious respiratory disease, but a study published on October 8th in PLOS Pathogens suggests that infected cells in breast tissues could play a role in virus transmission from mothers to breast-feeding infants and vice versa using a ferret model. Read More

TWiP 101: Is it round or is it flat?

The doctors TWiP solve the case of the Woman with White Worms, and explore the role of a secreted growth factor from a carcinogenic parasite in wound healing and angiogenesis.

HIV cure research: NIH scientists create 2-headed protein to deplete HIV reservoir

Scientists at the National Institutes of Health (NIH) have created a protein that awakens resting immune cells infected with HIV and facilitates their destruction in laboratory studies. The protein potentially could contribute to a cure for HIV infection by helping deplete the reservoir of long-... Read More

Hibernating bats mount a partial immune response against white nose fungus

White-nose syndrome (WNS), an invasive skin infection caused by the Pseudogymnoascus destructans (Pd) fungus has killed millions of bats since it was first seen in North America in 2007. A analysis of gene expression in hibernating bats infected with the destructive fungus published on October 1... Read More

3 ANTIBIOTICS GANG UP TO KILL DEADLY STAPH

As a trio, three antibiotics that aren’t individually effective against a drug-resistant staph infection killed the deadly pathogen in test tubes and mice. Read More

Paper-based test can quickly diagnose Ebola in remote areas (video)

BOSTON, Aug. 18, 2015 -- When a fever strikes in a developing area, the immediate concern may be: Is it the common flu or something much worse that requires quarantine? To facilitate diagnosis in remote, low-resource settings, researchers have developed a paper-based device that changes color, d... Read More

Guinea reports Ebola-free week, but Sierra Leone has 5 cases

For the first time in more than a year, Guinea passed a week without a new lab-confirmed Ebola case, but the news out of West Africa last week was tempered by a flare-up of activity in Sierra Leone, the World Health Organization (WHO) reported today in its latest update. Read More

Strategies to decrease bacterial colonization

Among the bacterial infections that are most difficult to treat, chronic infections associated with bacterial biofilms are one of the most hazardous. Bacterial biofilms are densely packed communities of microbial cells surrounded with secreted polymers. In her doctoral thesis, chemist Shoghik Ha... Read More

VIRUSES FROM NEWBORN GUT ARE NEW TO SCIENCE

Shortly after a baby’s birth, bacteria aren’t the only invaders to colonize the gut. Viruses move in, too, according to new research. Read More
