Cas4-like Protein in Giant Viruses

https://doi.org/10.1016/j.isci.2018.04.001 SUMMARY: Mimiviruses are giant viruses that co-evolved with eukaryotic hosts and virophages. Virophages are tiny viruses that hijack the viral factories giant viruses set up inside the host. Just as the eukaryotic host and virophages have evolved a sort of symbiotic relationship to defend against giant virus attacks, giant viruses have also evolved a… Continue reading Cas4-like Protein in Giant Viruses

Role of CRISPR in Pathogenic Bacteria

The Role of CRISPR-Cas Systems in Virulence of Pathogenic Bacteria SUMMARY: The introduction talks about the different types of CRISPR-Cas systems and the first section explains how these CRISPR systems were used in the past (mostly to see the genotypic relationship between bacteria). It wasn’t until 2013 that scientists discovered CRISPR was a type of… Continue reading Role of CRISPR in Pathogenic Bacteria

Phage Therapy on Infected Graft

Phage treatment of an aortic graft infected with Pseudomonas aeruginosa SUMMARY: The first part of this article talks about using phage and antibiotics (separately and together) in vitro to reduce bacteria biofilm. Researchers found that phage alone was enough to reduce biofilm to almost zero; however, there is the concern (noted in other papers) that… Continue reading Phage Therapy on Infected Graft
