bc200 gene mobility

We had a similar stir years ago regarding horizontal gene transfer that ended up being simple contamination. I wonder if the researchers have ruled out a lab-based artifact before claiming the gene actually jumped.
The study notes this was specifically an orthopoxvirus, which are known for their unusually large genomes. This means the swap meet might be more about the virus's appetite for host DNA than the bc200 gene's inherent mobility.
Correct, and the incorporation of long non-coding RNAs like bc200 is particularly interesting. It likely serves as a tool for the virus to manipulate the host's epigenetic landscape, which provides a functional reason for the transfer.
From a public health standpoint, this raises a question about diagnostic stability. If viral genomes can pick up host genes on the fly, our current PCR primers might miss modified strains.
