Since Acanthamoeba polyphaga mimivirus (APMV) was identified in 2003, several other giant viruses of amoebae have been isolated, highlighting the uniqueness of this group. In this context, the tupanviruses were recently isolated from extreme environm

The Acanthamoeba polyphaga mimivirus (APMV) was first isolated during a pneumonia outbreak in Bradford, England, and since its discovery many research groups devoted efforts to understand whether this virus could be associated to human diseases, in p
