Same guy, also ended: https://podcasts.apple.com/us/podcast/a-gobbet-o-pus/id32920...
A lot of knowledge there if you listened end to end.
And microbe.tv took over puscast: https://www.microbe.tv/puscast/ , the hosts try their best but I'd still rather have Mark Crislip.
They have two podcasts for microbiology. This Week in Microbiology is similar to TWiV in that they usually cover papers or talk to a researcher about a paper. Matters Microbial doesn't cover papers but has interviews with working microbiologists where they geek out about their research.
They also have a great podcast on immunology with very enthusiastic hosts, one for neuroscience, one for parasitism, and a couple of infectious disease/clinical/public health podcasts.
The great thing about all of them is how infectious the hosts' enthusiasm is.
Well, if there's one group I would expect that of...
I haven't listened to any of these because I can't stand Mark Martin, and I'm hoping having his own show keeps him out of TWiM.
