Back-to-back papers! Following our recent work on Restriction-modification systems in 𝘕𝘦𝘪𝘴𝘴𝘦𝘳𝘪𝘢 𝘨𝘰𝘯𝘰𝘳𝘳𝘩𝘰𝘦𝘢𝘦, we now show that targeting type I CRISPRi to the leading strand of the 𝘨𝘢𝘳 R-loop/G-quadruplex region upstream 𝘱𝘪𝘭𝘌 restores pilin antigenic variation in a G4-locked strain or a 𝘨𝘢𝘳 mutant.

Are restriction/modification modules only used for host defense? @selmamhm.bsky.social shows an alternative use. "Restriction-modification systems are required for Neisseria gonorrhoeae pilin antigenic variation" www.pnas.org/doi/10.1073/pnas.2602688123 #Microd #Microsky. #Microbiology

And there it is: FDA has approved zoliflodacin for gonorrhea as well. That makes two new antibiotics to treat this STI and it means a fascinating debate now about how to use these drugs in a way that will delay resistance as much as possible… 🧪 #IDsky

Publicly Available Neisseria Gonorrhoeae Genomes Predominantly Represent In Vitro-Derived Nonpiliated Variants
Most Neisseria gonorrhoeae clinical isolates are piliated but lose piliation during laboratory passage. However, most public genomic sequences are from non
