Fourth blog post is due on 

April 26, 2018 by midnight

Yes, I’ve extended the deadline by one week (since I didn’t put up instructions on time!)

This one is pretty straightforward though.  The topic is “Blogger’s choice”.  You can choose anything about your microbe that you haven’t already talked about.  This could be its pathogensis, its ecology, its environmental importance, its genetics, antibiotic resistance, vaccines, anything you want.  

Other things that are due by this day:  your 5 comments (yep, this is extended too), and whatever adjustments you make to the appearance of your blog.  Happy blogging!
