We examined the serum antibody response to ZIKV and other flaviviruses in Brazilian women giving birth during the 2015–2016 outbreak. Infected pregnancies with intermediate or higher ZIKV antibody enhancement titers were at increased risk to give birth to microcephalic infants compared with those with lower titers (P

Zika virus (ZIKV) was a re-emerging arbovirus associated with Guillain–Barré Syndrome in adult and congenital Zika syndrome in fetus and infant. Although ZIKV was mainly transmitted by mosquito bites, many sexual transmission cases have been reported since the outbreak in 2015. ZIKV can persist in testis and semen for a long time, causing testicular tissue damage and reducing sperm quality. However, no drug has been approved for prevention or treatment of ZIKV infection, especially infection in male testicular tissue. Previously reported peptide Z2 could inactivate ZIKV, inhibiting ZIKV infection in vitro and ...

her For the first 60 years following its isolation, Zika virus (ZIKV) remained a relatively poorly described member of the Flaviviridae family. However, since 2007, it has caused a series of increasingly severe outbreaks and is now associated with neurological symptoms such as Guillain-Barré syndrome and congenital Zika syndrome (CZS). A number of reports have improved our understanding of rare complications that may be associated with ZIKV infection in adults, the areas of the body to which it spreads, and viral persistence in various tissues. Likewise, studies on the effect of ZIKV infection during pregnan...

In this study, we report for the first time that highly diluted ethanol extracts prepared from basil leaves can effectively inhibit ZIKV replication in Vero E6 cells with a half maximal inhibitory concentration (IC50) value of 1:134. The diluted extract as well as the amount of ethanol that goes into its preparation have been found to be completely non-toxic to the above mentioned cell line. The extract seems to inhibit the virus at the step of attachment and entry into the host cell. The specific inhibition of ZIKV observed using the basil leaf extract suggests a new alternative mode of treatment against flavivirus. Keywo...

To prevent future ZIKV outbreaks and protect persons at risk for severe disease, we developed two live-attenuated vaccine (LAV) candidates containing 10- or 20-nucleotide deletions in the 3′UTR of the viral genome (Δ10 and Δ20).

Abstract Zika virus (ZIKV) has drawn global attention as the etiologic agent of Zika Congenital Syndrome in babies born to infected pregnant women. To prevent future ZIKV outbreaks and protect persons at risk for severe disease, we developed two live-attenuated vaccine (LAV) candidates containing 10- or 20-nucleotide deletions in the 3'UTR of the viral genome (Δ10 and Δ20). After a single-dose immunization, both Δ10 and Δ20 LAVs protected mice and non-human primates against ZIKV infection. Here, we characterized the stability, safety, and efficacy of the LAVs after continuously culturing th...

ard Hildt Infection with Zika virus (ZIKV) came first to public attention after it was found to be associated with congenital microcephaly during the outbreak in Brazil (2015–2016). Diagnosis of ZIKV suffers from extensive cross-reactivity with other Flaviviruses, which are circulating in many ZIKV epidemic areas. Due to the fatal outcome of ZIKV infection during pregnancy, detailed knowledge about neutralizing and non-neutralizing epitopes is crucial for the development of robust detection systems of protective antibodies. Therefore, additional information about ZIKV immunogenicity and antibody response is requi...

During the 2015-16 Zika virus (ZIKV) outbreak in Brazil, hospital surveillance for congenital Zika infection (CZI) was conducted at the Jos é Maria de Magalhães Neto reference maternity hospital, located in Salvador-Brazil, between February and December 20161. Normocephalic infants with prenatal exposure to ZIKV were recruited if their serological testing or a polymerase-chain-reaction assay (PCR) for ZIKV were positive. All their mot hers reported ZIKV infection symptoms during pregnancy and had anti-ZIKV IgG positivity at the time of delivery.

Conclusions: We observed a high frequency of gestational and neonatal complications in pregnant women who acquired Zika infection, especially in early pregnancy, resulting in a broad spectrum of clinical manifestations. Preventive measures are urgently needed to reduce the clinical burden during future Zika outbreaks.
