Are you a bacterial geneticist looking for a football player to root for this year? Obvious choice is LAC McConkey.
His name is Ladd McConkey and he plays for LAC. Went to microbiology powerhouse Georgia so that checks out.

My lab is doing the hard work to prepare for a conference next month: taste testing to figure out if egg sandwiches should be served on English muffins or donuts.

Great to have my former labmate and @uwmadisonmdtp.bsky.social alum Sarah Studer back in Madison. Of course we celebrated with Babcock Ice Cream!

Hmm… I don’t see one of the most exciting results in the thread above so adding again: The paper shows that the E. berryi isolates encode a Type VI secretion system and that those systems are functional in culture and during squid colonization.

Overall, our work suggests that the Hummingbird bobtail squid (the bigger one!) is likely to be a valuable comparative model for mechanistic studies of symbiosis.

Finally, early host responses to symbiosis including apoptosis and hemocyte migration are conserved in the Hummingbird bobtail.

Bacterial mutants that fail to engage in flagellar motility, SYP biofilm, or produce the symbiotic luminescence had identical phenotypes in the Hummingbird bobtail as they have in the Hawaiian bobtail squid.

Fluorescent protein-expressing strains revealed the crypt structure of the Hummingbird bobtail squid light organ, which strongly resembled that of the Hawaiian bobtail (3 crypts x 2 sides = 6 crypts per animal).

We started by isolating symbionts from the Hummingbird bobtail squid, and found that like the Hawaiian host, there is strong specificity with only being colonized by Vibrio fischeri.

Hector Burgos prepared a tome (!) of protocols on how to generate, compete, and analyze barcoded-deletions in Vibrio fischeri. Check it out if you'd like to apply these approaches! currentprotocols.onlinelibrary.wiley.com/doi/10.1002/...
