One of the team's discoveries, nicknamed the MiniFlayer, appears to attach itself to their helper virus so both viruses can invade their bacterial host at once.
Viruses are somehow even weirder than we thought. In a recent study published last month, scientists say they’ve discovered two new viruses that hijack the machinery of other bacteria-infecting viruses in order to replicate themselves. One of these vampiric viruses even acts the part, appearing to “bite” and latch onto their helper virus so that they can enter the bacteria at the same time. In the simplest of terms, viruses are tiny packages of genetic material, either DNA or RNA.
This discovery alone is interesting, since these would be the first satellite viruses known to rely on bacteriophages for replication . But it gets even freakier, since the Flayer system appears to feature some virus-on-virus nibbling. Satellites typically have their own means of entering and staying inside a cell unnoticed while they wait for a helper virus to come around; often this entails integrating themselves into the host cell’s genome.
