Are absolutely: Effects Of Zika Virus On Foetuses

Tampa, Https://amazonia.fiocruz.br/scdp/essay/essay-writing-format-cbse-class-12/godfather-moral-downfall.php Feb. They also report that the agent tizoxanide inhibits ZIKA virus in maternal decidual cells grown in the lab, offering promise for preventing perinatal transmission that can cause devastating malformations and brain damage in developing fetuses and infants.

Lockwood, MD, USF Health senior vice president, dean of the Zikka College of Medicine, and a professor of obstetrics and gynecology specializing in maternal-fetal medicine. The widespread global alarm caused by the spread of mosquito-borne Zika virus throughout the Americas in dissipated after the virus all but disappeared in Yet, resurgence remains possible in areas where the Aedes aegypti mosquito is prevalent, and there is no treatment or vaccine available for Zika virus infection.

While most Zika-infected adults show no symptoms, the virus can cause minor flu-like symptoms, and in rare cases has been associated with Guillain-Barre syndrome. However, Zika poses the most concern for pregnant women, because up Virud one in 10 newborns of affected mothers suffer Zika-associated birth defects, including smaller than normal head size microcephaly that can lead to developmental disabilities and other health problems. Zika has also been linked to pregnancy complications, including preterm birth, preeclampsia and miscarriage.

Moreover, timing appears important. Mothers infected in the first trimester are much more likely to have babies with severe Zjka birth defects than mothers infected in the third semester. The placenta, the organ supplying maternal oxygen and nutrients to the growing fetus, has ways to prevent most pathogens, including viruses, from crossing its protective maternal-fetal barrier. A subtype of fetally-derived placental cells known as syncytiotrophoblasts, in direct contact with maternal blood, are assumed to be the site where the Zika virus enters the placenta, leading to potential fetal infection.

However, Dr. Ozlem Guzeloglu-Kayisli said, these particular trophoblasts resist Zika virus attachment and replication. To learn more about how Zika gets through the placental wall, the USF Health team began by investigating the cellular and molecular mediators of Zika virus replication. Among their key findings, the researchers:.

Once inside the maternal cells, the Zika virus an RNA virus hijacks the cellular machinery to make proteins needed to copy its genetic material and churn out new viral Vurus. The drug has been shown preclinically to inhibit a broad range of flu-like viruses and is being tested clinically against coronavirus.

The finding warrants further testing of tizoxanide to block perinatal transmission of Zika virus and thereby protect the fetus from harmful outcomes, the researchers conclude. The University of South Florida is a high-impact global research university dedicated to student success. Over the past 10 years, no other O university in the country has risen faster in U.
