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.

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.
