I found several papers describing how to make agar or agarose embedded bacteria (namely P.aeruginosa strains), but I would like to see a movie to have a better idea.
There are papers using sepharose beads coated with PPD from Mycobacterium bovis for chronic lung infection models in mice, that may give you a place to start. The process we use is coupling the bacterial protein to these sepharose beads. I am not aware of any movies.
Chensue et al. 2007 should give you a starting place. I am originally from the Chensue lab and have done bead coupling, so if you have specific questions about how to perform the coupling I can answer them. Good luck!
Hi Antonio, contact Dr Alessadra Bragonzi at the San Raffaele Scientific Institute in Milan. Her group makes agar beads routinely and I think she just prepared a video for JOVE
