1. I think it's beautiful that the lab worker shows kindness and compassion to the giant rat by showing affection towards it and rubbing it at :09.. I would be too disgusted and wouldn't want to be near it
2. What a weird dog
3. What is it with Mandy? At first she was sniffing out bombs, now she's sniffing out tuberculosis?
4. Great
5. People need to stop giving rats such a bad name
6. In the near future, colonoscopies will be obsolete. The doctor will have you drop your pants and bring in a bloodhound to smell your butthole.
7. she is an ENORMOUS rat! very cool research...I have a ton of small animals, rodents, and I have even more respect for their intelligence, now! I have a history of cancer, and I always bug out a little, whenever I feel like my dogs are trying to tell me something 🐀🐀🐀
8. Damn they are huge
9. "I'm the Giant Rat that makes all of the rules,"
10. i did a rat dissection and feel bad now
11. Around 1:30, the narrator says "smell of the virus." Tuberculosis is caused by bacteria.

18. 0.31: "The rats can detect early signs of the virus" - this is erroneous. Tuberculosis is a bacterial infection, not viral.
