the impact of crispr-cas
what is crispr-cas?
all organisms are exposed to parasites, so they evolved a range of different immune mechanisms to defend themselves. about 10 years ago, scientists discovered that bacteria and archaea, generally regarded as primitive organisms, have a sophisticated adaptive immune system, known as crispr-cas (clustered regularly interspaced short palindromic repeats).
the discovery of the crispr-cas system has led to a sea of change in the microbiological sciences. since then laboratories all over the world have joined the race to understand and exploit crispr. the insights gained about this system led to applications in industry to protect bacterial species against their viral parasites. in addition, crispr-cas has been turned into a versatile genome editing method that has the potential to treat human genetic diseases.
why does crispr-cas matter to microbiology?
understanding how these systems work has been an important standalone basic science endeavour. more recently, harnessing crispr has opened the door to precision genome editing across all of life’s domains. these breakthroughs were recognised by the nobel committee who awarded the prize for chemistry to emmanuelle charpentier and jennifer doudna.

the world of phage
phages are composed of proteins and a dna or rna genome that can be very simple, containing four genes, or complex, with hundreds of genes. with the emerging threat of antimicrobial resistance, alternatives to antibiotics are needed, hence, could phage therapy be considered a viable option?
