A Special Journey...

- David Wolking

Today Dr. Liz Vanwormer is returning from Tanzania.  Liz has been working with the HALI team on PREDICT, and is leading a project investigating pathogen transmission between bats, monkeys, and people in the Udzungwa Mountains National Park and surrounding areas.  That's a pretty special project, and we'll learn more about it as it develops, but it's not our main focus.   

Our main focus today is bat poop.  Why?  Because we spend a lot of time and money collecting it.  We find bats, we sample them, collect their poop, put it in vials with a special preservative, and then freeze it in liquid nitrogen.  If the bats don't have poop, we swab them, using a very small tipped swab and yes, we lubricate the tip.  We are not sadists.  All of these poop and fecal swab samples are taken to our lab in Morogoro where our technician Ruth uses a special protocol to extract RNA from the poop.  Once we have the RNA, we use it to synthesize complementary DNA (cDNA), then we freeze that cDNA and use it to run our viral family screening tests to look for genetic evidence of viruses.  You can find a lot of viruses in bat poop.  

So, Dr. Liz is traveling with some special luggage - a liquid nitrogen charged dry shipper full of cDNA from bat poop.  It's pretty amazing that genetic material from bat shit collected deep in Tanzania's Southern Highlands will have traveled to Morogoro, Dar es Salaam, Nairobi, London, San Francisco, Napa, and finally to our UC Davis One Health lab.  Too bad it can't rack up frequent flyer miles....
