How bats carry deadly diseases without dying

[@Vox]

There’s so much more to talk about here! Definitely feel free to sound off in the comments about your love for bats and head to the description for a PILE of links to fascinating studies and articles that offer a deeper dive on some of the specifics. The jury is still out on whether bats carry more diseases than other mammals or if there are just many species of bats. There are around 1,400 types of bats in the world - that’s about 20% of ALL mammalian diversity. A paper published in 2021 found that the amount of viruses that bats carry is proportional to the diverse range of species: www.ncbi.nlm.nih.gov/pmc/articles/PMC7909788/. Thanks for watching! -Kim

without bats, the insect population would be out of control.

[@eugeneslim9108]

are they the more weighty factor than birds?

[@ianism3]

@@eugeneslim9108 probably depends on the region. also, they tend to operate at different times of day, so their prey is pretty different.

[@lancejacobs.]

Maybe certain areas.. but there are areas with no bats and the insect population is pretty stable

[@AsiniusNaso]

Bats have also been a long-time worry for pandemics because they can have millions of mammals living in close proximity, you know, like humans.

Bats are endangered in many places even though they are extremely valuable because of habitat loss and disruption of thei ecosystem

[@DemonCoreEntertainment]

I hate how the media portrays bats as some kind of flesh eating monster, I mean, these ain’t nothing but some Bird puppies

[@paulwary]

What about the mere fact of raising their temperature to 44 C when flying? Wouldn't that eliminate a lot of virus load by itself?

[@anhbindo]

I think so , even if the virus still alive its only choice now would be remain in dormant state and waiting for the environment becomes better ( probably during times when the bat hibernate maybe? )

[@napoleonibonaparte7198]

Bats: "Their entire existence as a flying mammal is an extreme stressor." And humans' existence as a mamma; is also an extreme stressor.

There was a disease in Canada a year or two back wiping out bats in the east and moving westward. I havent heard about it since, but I hope they figured it out and managed to save these little guys.

[@yourdaily_memer]

[@woltews]

I feel like there are 2 things not explained at all 1- what dos the metabolic output of flight have to do with response to a virus ( there are all kinds of stressors animals have why is flight so similar to a viral infection ) ? 2- How do bats blunt the effects of the body's response to infection without that also making the response ineffective in the first place ?

[@north6502]

I bet it has to do with their body temperature during flight, 44 is very high for a human fever, but in a bat it’d be normal

[@mikeyjhilli]

Agreed.

[@woltews]

@@north6502 looked up what it was for a squirrel and it seems to average around 40C depending on a bunch of factors so within 4 of the bat , also the bat spends most of its time not flying

2:56 is there something wrong with the X axis here? I find it hard to believe that there are mammals that weigh under 2 g. I mean I had a hamster, and I kept track of her weight, and she was between 120 and 130 g, she was nowhere near the size of a fruit bat.

[@HreForTheMusic]

Another way of looking at this topic is, a virus that can surive a bat body temp cannot be harmed by human fever (one of the main purposes of fever is to do that). So our response is not nearly as affective, making those viruses dangerous than one that came from another mamal.
