Why Fish In Captivity Get Sick
As some people may know I have been talking about how my fish have never gotten sick in decades and I have been offered many reasons why such as I am Lucky or my tank has some mysterious creature that eats parasites, my Undergravel sucks up parasites and diseases, the Ozone I use kills diseases (I have not used Ozone in almost 3 years) UV light won't allow diseases to flourish (I never used UV light) or a variety of other "explanations".
I am pretty sure I know the reason and I have known it for many years but never actually had proof. Now I do.
My wife has MS and has had it for over 20 years so I research all I can about it. My Grand Son and Granddaughter also have health problems that can be life threatening. Because of this I do a lot of researching of new therapies or any ideas or theories that may be pertinent to this.
Two of my friends are Neurologists and I have spoken to them on this also.
Ever since the 80s I have thought there was some kind of important connection between the organisms living in our, and animals guts and the brain. At first I figured it was slightly but not very important. Now I know differently.
I read all I can find on this relationship and in this months "Discover" magazine (Nov. 2020)
There are two articles on the subject. They mainly focus on mental health and Autism but they outline how gut microbes control our health. Something I have known all along but didn't put it all together so completely.
The article starts out by quoting the Doctor at UCLA in 1990. He started thinking about how tiny organisms, too small to be seen could function as "powerful, "self-contained machines" powerful enough to take over and destroy the Human body.
The gist of one of these articles is about a young boy who had Autism and severe gastrointestinal symptoms.
He then had new microbes introduced into his gut which changed everything. Within a year he was almost back to normal and no longer is considered to have Autism and his internal issues are also resolved.
"Our body, especially our intestines are teeming with thousands of types of bacteria but it was largely unknown how they affected the body besides causing illness.”
Then he thought, "Why would the human immune system which is designed to attack and destroy foreign invaders, allow hundreds of species of bacteria to live and thrive in our guts unmolested?"
The answer is, there must be some sort of benefit to both the microbes and the body.
A "Symbiotic System".
Early research was done on lab mice that were bred to have no bacteria in their bodies. It was found that those mice had a 30 to 40% reduction of a specific type of immune cell known as "helper T cells”.
Helper T cells help stop invading pathogens and it was found that germ free mice were far less robust than mice with a full complement of microbes.
Copper, antibiotics and most aquarium medications either kill or severely alter gut microbes
Those sterile mice were then given fecal transplants from healthy mice and within a month were just as healthy and had a strong immune response as healthy mice.
I realize mice, Humans and fish are different but we all evolved together and our gut microme, just as in a fish act very much the same in relation to health.
One of the biggest things this researcher found was a gut microbe named "B.fragilis" played a key role in preventing the immune system from attacking its host and protecting against autoimmune diseases. (We don't want to kill that one)
(I was very interested in this because my wife's MS is an autoimmune disease)
I don't know if fish get autoimmune diseases but it seems odd to me that many fish in quarantine or medicated for one disease, all of a sudden are afflicted with other, non-related diseases. You know and I know that is very common.
Quarantine by itself I don't feel will cause disease unless the fish is stressed as in a bare tank with PVC "decorations or if the fish is not being fed food with living bacteria (microbes) in it.
Getting back to the research. It was found that children with Autism had "leaky Gut Syndrome" which allowed microbes, one in particular called "4-ethylphenyl sulfate" to circulate in the blood.
Tests were performed on mice and it was found that if they injected 4-ethylphenyl sulfate into healthy mice, they were more easily startled and were less comfortable in large empty spaces than their untreated peers and an increase in anxiety-related behaviors.
Also (in mice anyway who have been given this molecule or have autism like symptoms) several important species involving the digestion of carbohydrates were severely depleted.
That sounds very similar to me to fish that are quarantined, on meds or not eating living bacteria and why many of them refuse to eat, stay hidden, and try to jump out or just die.
We humans are more bacteria than human. 1.3 to 1 to be exact. Our gut houses 100 trillion bacteria (I didn't count them) it is a complicated microbial universe which plays a very important part in our and our fish’s health.
These microbes help us digest food, keep harmful microbes at bay and control our emotions.
(Maybe Vulcans use these)
