A deadly fungus is attacking frogs' skin and wiping out hundreds of species worldwide. Can anyone help California's remaining mountain yellow-legged frogs? In a last-ditch effort, scientists are trying something new: build defenses against the fungus through a kind of frog vaccine.
This video discussed with a successful cure to an infection of a population of frogs,
The question the kept coming up was how long does the an outside factor (caregiver) should be administered a cure given that a single ration would cure a single generation of frogs (but not their siblings, unless those too will be given the cure..)
Immune system does not get registered across generations,
it only takes effect for the individual, but a cure can be delivered in mass quantities to apply multiple individuals in one go, over a long period of time, across several generations, to eventually (hopefully) eradicate a repeating infection 💉.
Genetic engineering of the packed genes (Chromosomes) in the individual's reproductive cells (for example, a sperm cell or an egg) is the most common way of passing information to the next generation, but is considered risky the very least ☣.
Aren't Any Exceptions?
The only natural way of a treatment to an individual to pass along to the next generation happens in some kind of mono-cell bacterias, which may develop immunity by mutation,
and exchange a splice of their genetic material (yep!) with another member of the same bacteria family, when the mono-cell, now with new genetic code replicate- the immunity, is, too, replicated to next generation.
(In multi-cell organisms- such as frogs, the genetic-exchange process is replaced with exchanging whole cells, namely '🐸 on 🐸 action' ;)
Cells protects the genetic material against mutations, so in a sense passing a genetic attribute such as immune-system response- will never happen,
instead, we are putting our faith in natural selection.. )
This way, a mutation in the bacteria (which is considered a rare occasion) can be indirectly responsible to a spread of an immunity (or any genetic variation in that matter) to a large number of individuals, quite fast.
*Also, This is why antibiotics shouldn't be taken excessively or stopped being administered too soon.. 👍
