Zika virus detection in urine from patients with Guillain-Barr é syndrome on Martinique, January 2016.

We report two cases of Guillain-Barré syndrome who had concomitant Zika virus viruria. This viruria persisted for longer than 15 days after symptom onset. The cases occurred on Martinique in January 2016, at the beginning of the Zika virus outbreak. Awareness of this possible neurological complication of ZikV infection is needed.

ConclusionsMany ZIKV predictions were published during the 2016 –2017 pandemic. The accessibility, reproducibility, timeliness, and incorporation of uncertainty in these published predictions varied and indicates there is substantial room for improvement. To enhance the utility of analytical tools for outbreak response it is essential to improve the sharing of model data, code, and preprints for future outbreaks, epidemics, and pandemics.

Zika virus NS2A and NS4A are the major antagonists that reduce IFN-β promoter activity induced by the MDA5/RIG-I signaling pathway. J Microbiol Biotechnol. 2019 Sep 30;: Authors: Ngueyen TTN, Kim SJ, Lee JY, Myoung J Abstract Zika virus (ZIKV) is a mosquito-transmitted emerging Flavivirus causing the Guillain-Barré syndrome and microcephaly in adults and fetuses, respectively. Since ZIKV was first isolated in 1947, severe outbreaks have occurred at various places worldwide, including in the Yap Island in 2007, in the French Polynesia in 2013, and in Brazil in 2015. Although incidences of Z...

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...

The U.S. diagnostic market celebrated three regulatory firsts last week.  1. FDA Authorizes Marketing of First Zika Test Until now, tests for detecting Zika virus immunoglobulin (IgM) antibodies in blood were only authorized for emergency use under FDA's Emergency Use Authorization (EUA) authority. On Thursday, the agency said it has authorized marketing of the ZIKV Detect 2.0 IgM Capture ELISA under the agency's traditional premarket authority. The test is manufactured by InBios International. “At the onset of the Zika virus outbreak, when little was known about the disease or how...

Conclusion: Our results are similar to those reported from the state of Veracruz, Mexico, in which out of 33 samples of urine of patients with GBS two had a positive RT-PCR for ZIKV. Simultaneous processing of serum, CSF, urine, and saliva by RT-PCR may increase the success of diagnosis of GBS associated to ZIKV. Introduction In April 2016, a report of Epidemiological Surveillance for Zika virus (ZIKV) disease in Mexico reported 93 autochthonous laboratory-confirmed cases, collected between November 2015 and February 2016, and distributed amongst eight states of the country (1). In these patients, clinical manifest...

In this study, we evaluated ATA as a potential antiviral drug against ZIKV replication. The antiviral activity of ATA against ZIKV replication in vitro showed median inhibitory concentrations (IC50) of 13.87 ± 1.09 μM and 33.33 ± 1.13 μM in Vero and A549 cells, respectively; without showing any cytotoxic effect in both cell lines (median cytotoxic concentration (CC50)> 1,000 μM). Moreover, ATA protected both cell types from ZIKV-induced cytopathic effect (CPE) and apoptosis in a time- and concentration-dependent manner. In addition, pre-treatment of Vero cells with ATA for up to 72 h also resulted...

Conclusions Apart West Nile virus (78), thousands of congenital microcephaly cases, fetal brain tissue damage and neurological syndromes have been associated with ZIKV infection. Unfortunately, the epidemics of this mosquito born, and a relative stable virus is on a rise. Although congenital microcephaly is a rare disorder however, due to lack of standardized diagnostic test facilities, the incidence in the geographically widespread ZIKV epidemic regions is higher. Animals studies showed that ZIKV is a neurotropic virus. It directly targets the developing embryonic brain cells by inducing apoptosis, cell-cycle arrest, and...

Conclusion and Perspectives Arbovirus infections, such as CHIKV, have been growing worldwide and are becoming a major public health problem, especially in immuno-compromised classes such as children and the elderly. CHIKV is dangerous since it can cause arthritis, fever and other impairments, making it necessary to seek new ways to counter the proliferation of this virus. Knowing the vector’s competence is fundamentally important, including an understanding of the vector virus interaction and the modulation of this interaction. Despite advances in the knowledge of mosquito competence in the transmission of CHIKV, li...

The objectives of this study were to compare the historic African MR766 ZIKV strain with two epidemic Brazilian strains (BR15 and ICD) for their abilities to initiate viral infection and to confer neurocytopathic effects in the human brain’s SNB-19 glial cells, and further to determine which part of the ZIKV structural proteins are responsible for the observed differences. Our results show that the historic African (MR766) and epidemic Brazilian (BR15 and ICD) ZIKV strains are different in viral attachment to host neuronal cells, viral permissiveness and replication, as well as in the induction of cytopathic effe...
