Review on Ebola evolution in Nature

The 2013-2016 Ebola epidemic in West Africa was of unprecedented size and devastation, but also stands a landmark for infectious disease genomics. By sequencing virus genomes directly from patient samples, scientists are now able to investigate how viruses evolve, transmit between individuals, and spread across country borders during outbreaks, directly informing infection control.

Zika sequences from Miami mosquitoes

Data here. Protocol here. Three pools of Aedes aegypti mosquitoes collected in Miami Beach on August 22nd and 23rd, 2016, were found to be infected with Zika virus. Through our collaborators, Scott Michael and Sharon Isern from Florida Gulf Coast University, we recently received samples of these mosquitoes for sequencing using our amplicon-based protocol for MiSeq.

Zika sequence from local Florida transmission

Data here. Protocol here. In collaboration with Dr. Diogo Magnani in the Watkins Laboratory in the Dept. of Pathology at the University of Miami's Miller School of Medicine, we recently received plasma and saliva from two people with Zika virus infections living in the Miami area. Using our amplicon-based approach previously used to sequence Zika virus from travel-related Zika virus cases in…

Travel-related Zika cases in Florida

Figure 1. Coverage plots of the included samples. Data here. Protocol here. In a collaboration with Scott Michael and Sharon Isern from Florida Gulf Coast University and Florida Department of Health, we have recently received several travel-related cases detected across Florida. We have now managed to sequence Zika virus genomes from three of these case and the data and analyses can be accessed here. (more…)

MiSeq protocol for Zika virus sequencing

Amplicon-based protocol for Zika virus sequencing on the Illumina MiSeq The protocol can be found here. Figure 1. Sequencing coverage of the Zika virus genome. Zika virus strain PRVABC59 spiked with Hela RNA was PCR amplified using 70 virus-specific primers in two reactions, prepared for sequencing using the Kapa Hyper prep kit, and sequenced using the MiSeq v2 500 cycle…

Zika virus pilot (update)

We have now received several hundred de-identified clinical samples from the Dominican Republic and Colombia. Unfortunately, they all have extremely low viral lows (Ct values > 38 in the few that are positive), so we’re continuing our technology development. We are following a couple of different strategies: (more…)

Zika virus pilot

We recently received plasma samples from Zika virus (ZIKV) patients in Colombia. We performed QC on the samples and unfortunately very few had detectable levels of ZIKV by qPCR. We extracted RNA from two of these patient samples (Z184 and Z186), as well as a positive control (seed stock of the Malaysian strain P6-740 passaged once on BHK-21 cells) kindly…

Feature in Politiken

The leading Danish newspaper Politiken had a feature on our work in the September 20th 2015 Sunday section. The article discusses our past and ongoing work with Lassa and Ebola. The full feature describes how we have investigated both Lassa and Ebola virus evolution based on our most recent papers in Cell and Science. (more…)
