Meet Pseudomonas syringae, the ice-forming bacteria that makes pumpkins warty
Since fall is my favorite season, I decided to see if there’s a microbe that’s unique to pumpkins. A quick search told me no, not really, but I also found that Pseudomonas syringae caus…

MICROBES IN FOCUS · 21/30 | Pseudomonas granadensis

Strain DE was recovered from a burnt site after the Los Guájares wildfire and showed siderophore production in our screening.

Even the species name keeps the story close to home!

→ What they did
Researchers demonstrated that for Pseudomonas aeruginosa bacteria protected by the CRISPR system, survival strongly depends on the specific type of virus they encounter, rather than always providing a benefit.
