37. The Problem
first Identified here:
(Banarjee et al, 2018) + Michelle Baker, CSIRO
Tools to study pathogen-host interactions in bats
ncbi.nlm.nih.gov/labs/pmc/artic…
38. Repeat (1)
Primary cells can also harbor latent viruses that can become reactivated during in vitro cultivation when the cells are outside the host and isolated from other components of the immune system that would otherwise control virus replication
39. Repeat (2)
"Cell lines from any species of bat should therefore only be handled under controlled biosafety conditions and thoroughly tested before being used for experimental studies. This is also a limitation when working with wild-caught bats"

41. Live Bats at #WIV
In addition to cell lines, there is a need for lab bred bats with known infection status for ex & in vivo experiments. Establishing a wild-caught bat colony is challenging but achievable with sufficient resources to house the bats
42. 2015 #WIV Bat Cell Line Experiments
