Vertical transmission of African-lineage Zika virus through the fetal membranes in a rhesus Macaque (Macaca mulatta) model

This study shows ZIKV can transmit vertically through fetal membranes, not the placenta, in rhesus macaques.

Primary infection with Zika virus provides one-way heterologous protection against Spondweni virus infection in rhesus macaques

This study shows that ZIKV infection protects against SPONV in rhesus macaques, but not vice versa, suggesting one-way cross-protection between the viruses.

Frequent first-trimester pregnancy loss in rhesus macaques infected with African-lineage Zika virus

This study shows that African-lineage ZIKV infection in early first trimester causes high pregnancy loss in rhesus macaques, regardless of SIV status.

Infection of the maternal-fetal interface and vertical transmission following low-dose inoculation of pregnant rhesus macaques (Macaca mulatta) with an African-lineage Zika virus

This study shows African-lineage Zika virus can be vertically transmitted to rhesus macaque fetuses with a low dose, similar to Asian-lineage viruses.

Fetal loss in pregnant rhesus macaques infected with high-dose African-lineage Zika virus

This study shows that high-dose African-lineage Zika virus infection in late first trimester pregnant rhesus macaques causes frequent fetal loss.

Prior dengue immunity enhances Zika virus infection of the maternal-fetal interface in rhesus macaques

This study shows that prior dengue virus immunity enhances Zika virus infection at the maternal-fetal interface in rhesus macaques but does not affect plasma replication or fetal outcomes.

Rapid evolution of enhanced Zika virus virulence during direct vertebrate transmission chains

This study shows ZIKV adapts more rapidly to mice during direct transmission compared to mosquito or alternating host transmission, with a virulence-enhancing mutation emerging.

Quantitative definition of neurobehavior, vision, hearing and brain volumes in macaques congenitally exposed to Zika virus

The paper assesses the feasibility of using a macaque model to study neurodevelopmental deficits from congenital Zika virus exposure and estimates required sample sizes for future studies.

Primary infection with dengue or Zika virus does not affect the severity of heterologous secondary infection in macaques.

This study investigates whether prior dengue or Zika virus infection affects the severity of subsequent heterologous secondary infections in macaques, finding no significant impact on clinical outcomes.

Molecularly barcoded Zika virus libraries to probe in vivo evolutionary dynamics

This paper uses molecularly barcoded Zika virus to study in vivo infection dynamics in pregnant and non-pregnant macaques and mosquitoes, finding stable lineage proportions during acute infection but a rapid decline in complexity post-infection in pregnant animals.

Ocular and uteroplacental pathology in macaque congenital Zika virus infection

This study reports ocular and uteroplacental pathology in rhesus macaques infected with ZIKV during pregnancy, showing prolonged viral replication and severe fetal outcomes.

Highly Efficient Maternal-Fetal Zika Virus Transmission in Pregnant Rhesus Macaques

This study infects pregnant rhesus macaques with ZIKV and observes prolonged maternal viremia and fetal tissue infection, indicating efficient vertical transmission.

Oropharyngeal mucosal transmission of Zika virus in rhesus macaques

This study assesses the risk of Zika virus transmission through mucosal contact in rhesus macaques, finding that oral secretions from infected individuals pose a low transmission risk.
