Some viruses replicate in just archaea: these are generally DNA viruses with abnormal and at times one of a kind shapes.[4][55] These viruses have already been studied in the majority of depth within the thermophilic archaea, notably the orders Sulfolobales and Thermoproteales.[194] Defences from these viruses include RNA interference from repetitive DNA sequences in just archaean genomes which are related to the genes from the viruses.
Not all virus bacterial infections develop a protecting immune response in this manner.
