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.
New research led by scientists at The Rockefeller University in New York may help explain why Zika virus infection causes birth defects in some children but not others. The study, which will be published August 14 in the Journal of Experimental Medicine, suggests that the risk of developing an abnormally small head (microcephaly) depends on the types of antibody produced by pregnant mothers in response to Zika infection.
New research suggests that 32% of children up to the age of 3 years who were exposed to the Zika virus during the mother’s pregnancy had below-average neurological development. Also, fewer than 4% of 216 children evaluated had microcephaly —a smaller-than-normal head that is one of the hallmarks of the mosquito-borne disease. The heads of two of those children grew to normal size over time, the researchers reported.
In a new study, researchers with the UF Institute of Food and Agricultural Sciences and the University of Southern Mississippi examined how quality and quantity of food ingested by the yellow fever mosquito affect its biology, including its ability to become infected by, and potentially transmit, the Zika virus.
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.
Kansas State University researchers are helping battle most of the nation's top-priority zoonotic diseases.
In experiments with pregnant mice infected with the Zika virus, Johns Hopkins Medicine researchers report they have successfully used a long-standing immunosuppressive drug to diminish the rate of fetal deaths and birth defects in the mice’s offspring.
UF/IFAS scientists zeroed in on the Florida mosquitoes because most of the studies done on “vector competence” to date have been conducted on species in Africa and Asia.
Texas Biomedical Research Institute and UT Health San Antonio have signed an animal care and joint research agreement to move dozens of important research animals from the Sam and Ann Barshop Institute for Longevity and Aging Studies to the Southwest National Primate Research Center (SNPRC) on the Texas Biomed campus.
Researchers in Chapel Hill, N.C., and Tokyo have discovered a mechanism by which liver cells intrinsic resistance to diverse RNA viruses is regulated. These results have implications for for cellular responses to hepatitis, dengue and Zika.
New approach for delivery of DNA-encoded monoclonal antibodies (DMAbs) has been reported by Wistar scientists. This new technology allows direct production of monoclonal antibody-like molecules in living animals.
In January scientists at Vanderbilt University Medical Center (VUMC) and colleagues in Boston, Seattle and St. Louis were given an audacious goal to develop — in 90 days — a protective antibody-based treatment that potentially will stop the spread of the Zika virus.
As many as a billion people could be newly exposed to disease-carrying mosquitoes by the end of the century because of global warming, says a new study that examines temperature changes on a monthly basis across the world.
Most emerging infectious diseases affecting people are zoonotic — they make the jump from other animals to humans. Transmission, however, is a two-way street. These zoonotic diseases can also jump from humans to other animals. Even if a disease is eradicated in humans, it can live on in animals that act as reservoirs, ensuring that the risk of human infection is never entirely eradicated.
This study is the first to report a possible mechanism for the enhancement of Zika virus progression during pregnancy in an animal model.
The higher a person’s immunity to dengue virus, the lower their risk of Zika infection, an international team of scientists led by the University of Pittsburgh Graduate School of Public Health, Yale School of Public Health and University of Florida report today in the journal Science.
A collaboration of scientists including Professor Jean Patterson, Ph.D., of Texas Biomedical Research Institute, is working on a new way to detect Zika virus that will help guide clinicians in their treatment of patients with the disease. The test uses optofluidic chips to screen bodily fluids (blood, urine, semen) for the presence of the virus. This new approach will also help pinpoint the stage of the disease. Researchers at the University of California at Santa Cruz, Brigham Young University, and the University of California at Berkeley developed the technology being tested.
Scientists at Vanderbilt University Medical Center and colleagues in Boston, Seattle and St. Louis are racing to develop — in a mere 90 days — a protective antibody-based treatment that can stop the spread of the Zika virus.
With winter temperatures in Maricopa County rarely dipping below freezing--60 degrees and raining, like today, is one of its more wintry days--Arizona is a perfect home for virus-carrying mosquitoes to overwinter, allowing the virus to survive.
