Invasive mosquitoes at the northern limit of their current range are surviving conditions that are colder than those in their native territory. This new evidence of rapid local adaptation could have implications for efforts to control the spread of this invasive species.
As part of a program called the Congressionally Directed Medical Research Program, the DOD is awarding Texas Biomedical Research Institute $2 million over the next three years to study a promising experimental Zika vaccine.
Ron Trewyn, Kansas State University NBAF liaison, writes to encourage people to watch THE HOT ZONE, a National Geographic limited series inspired by two Kansas State University veterinarians and leaders and their work during the 1989 Ebola-related outbreak in Virginia.
By age 12 to 18 months, 6.25% of children exposed to Zika during their mothers’ pregnancies had eye abnormalities, 12.2% had hearing problems, and 11.7% had severe delays in language, motor skills and/or cognitive function. In all, 14.5% had at least one of the three abnormalities.
A mouse mother's prior dengue immunity would protects her unborn pups from devastating brain defects such as microencephaly associated with ZIKV. These findings could guide development of more effective flavivirus vaccines and hint at what types of immune responses are maximally protective against fetal brain damage after Zika invasion.
A collaboration between researchers at the University of North Carolina at Chapel Hill Gillings School of Global Public Health, RTI International and the UNC School of Medicine has resulted in the first study to assess and compare United States travelers’ knowledge levels about the Zika virus across three regions
Two viruses closely related to Zika – West Nile and Powassan – can spread from an infected pregnant mouse to her fetuses, causing brain damage and fetal death, according to a new study from Washington University School of Medicine in St. Louis. The findings suggest that Zika may not be unique in its ability to cause miscarriages and birth defects.
An interferon cell receptor spurs cell suicide in fetuses infected with the Zika virus and could play a role in certain pregnancy complications.
More than 90 percent of study volunteers in the 3 trials who received the investigational vaccine demonstrated an immune response to Zika virus.
A new study demonstrates that outbreaks of mosquito-borne viruses Zika and Chikungunya generally occur about three weeks after heavy rainfall. Researchers also found that Chikungunya will predominate over Zika when both circulate at the same time.
California researchers have discovered that a medication used to prevent and treat malaria may also be effective for Zika virus. The drug, called chloroquine, has a long history of safe use during pregnancy, and is relatively inexpensive. The research was published today in Scientific Reports.
In a cover story published this week in the Ecological Society of America’s premier journal, Frontiers in Ecology and the Environment, Kevin J. Gutzwiller, Ph.D., professor of biology in Baylor University’s College of Arts & Sciences, and co-authors harnessed existing technology to help recreation ecologists and managers better understand and minimize those recreation disturbances to wildlife.
Researchers at the University of California San Diego School of Medicine, with colleagues in Brazil, report that the Zika virus is transmitted from mother to fetus by infected cells that, ironically, will later develop into the brain’s first and primary form of defense against invasive pathogens.
UCLA researchers have developed an improved technique for creating simplified human brain tissue from stem cells. Because these so-called “mini brain organoids” mimic human brains in how they grow and develop, they’re vital to studying complex neurological diseases.
EL PASO, Texas - West Nile virus is no stranger to the U.S.-Mexico border; thousands of people in the region have contracted the mosquito-borne virus in the past. But could this previous exposure affect how intensely Zika sickens someone now?
According to researchers at the University of Wisconsin–Madison who conducted studies with monkeys, casual contact like kissing or sharing a fork or spoon is not enough for the virus to move between hosts. Their findings were published today (Aug. 1, 2017) in the journal Nature Communications.
Antibody’s molecular structure reveals how it recognizes the Zika virus
The new Upper Midwestern Center of Excellence in Vector Borne Diseases, led by the University of Wisconsin–Madison, this week identified the Asian tiger mosquito, which can spread the Zika virus, for the first time in Wisconsin.
A University of Florida entomologist is working with other scientists to detect the Zika virus in minutes, rather than days or weeks, allowing for faster and more targeted mosquito control practices and detection in patient samples.
UF/IFAS entomology associate professor Chelsea Smartt led a research team that found Zika RNA in Aedes albopictus. That’s not the species -- known as Aedes aegypti -- most often associated with Zika. But scientists have never discounted Aedes albopictus as another possible carrier of the potentially deadly virus.
A study published today reports that a team led by Indiana University scientists has mapped a key protein that causes the Zika virus to reproduce and spread.
In a new paper, researchers at University of California San Diego School of Medicine, along with colleagues in Brazil and Spain, describe the phenotypic spectrum or set of observable characteristics of congenital Zika (ZIKV) syndrome, based upon clinical evaluations and neuroimaging of 83 Brazilian children with presumed or confirmed ZIKV congenital infections.
Although Zika and dengue are considered different virus “species,” they are so closely related that the immune system treats Zika just like another version of dengue, report researchers at La Jolla Institute for Allergy and Immunology. Their latest study, published in the March 13, 2017, advance online edition of Nature Microbiology, shows that pre-existing immunity to dengue virus modulates the magnitude and breadth of the immune system’s T cell response to Zika.
Zika virus could be transmitted by more mosquito species than those currently known, according to a new predictive model created by ecologists at the University of Georgia and the Cary Institute of Ecosystem Studies.
It’s been one year since the World Health Organization (WHO) declared Zika a public health emergency.The virus, transmitted through the Aedes aegypti mosquito, has since been declared to be a long-term problem rather than an emergency, but Zika continues to concern health professionals. At the Eck Institute for Global Health at the University of Notre Dame – a global leader in the study of Aedes aegypti – the vector-borne illness is one researchers hope to better understand.
The worst of the global Zika virus outbreak may be over but many key questions remain, such as why the virus persists in certain tissues after the systemic infection has cleared; how does the immune system counteract the virus and protect against reinfection; what determines the likelihood of long-term complications?
Mosquito surveillance efforts led by Iowa State University in 2016 found neither of the two species associated with the transmission of Zika virus. West Nile virus appeared more frequently in 2016 than it did in 2015.
Whitehead Institute researchers provide insight into a specific gene pathway that appears to regulate the growth, structure, and organization of the human cortex. They also demonstrate that 3D human cerebral organoids can be effective in modeling the molecular, cellular, and anatomical processes of human brain development.
According to the World Health Organization, Zika is no longer a global emergency. However, in South Texas, we now have the first case of Zika transmitted by mosquitoes locally. This is only the second state in the United States to report a case of local transmission of the disease.
As scientists race to create a vaccine for the Zika virus, new research from the University of Georgia suggests almost half of Americans wouldn’t be interested in getting the shot even if public health officials recommended it for them.
A team of scientists led by researchers at the University of Georgia has developed a new mouse model that closely mimics fetal brain abnormalities caused by the Zika virus in humans.
Researchers at Vanderbilt University Medical Center and Washington University School of Medicine in St. Louis, Missouri, have isolated a human monoclonal antibody that in a mouse model "markedly reduced" infection by the Zika virus.
Researchers at Washington University School of Medicine in St. Louis and Vanderbilt University School of Medicine have identified a human antibody that prevents, in pregnant mice, the fetus from infection and the placenta from damage. The antibody also protects adult mice from Zika disease.
A new study shows that Zika targets the male reproductive system, at least in mice. Three weeks after Zika infection, male mice had shrunken testicles, low levels of sex hormones and reduced fertility. The results suggest that Zika infection may interfere with men’s ability to have children.
In a collaborative effort with scientists at six Colombian hospitals, Johns Hopkins Medicine researchers report what they believe to be the strongest biological evidence to date linking Zika virus infection and Guillain-Barré syndrome.
