Gerald Bassleer examines a Polypterus senegalensis with systemic bacterial infection. Dissection reveals necrotic gills, liver hemorrhages, and gas-filled intestines. He recommends antibiotics and probiotics, and suggests checking food quality and tank pollution as sources.

Hello, dear aquarist, welcome again to my.
Cases of fish diseases.
And Today it's number 156 about Polypterus, Polypterus senegalensis, which were showing a bad behavior and were dying. So I will show you the video of the fish in the aquarium and my microscopic findings after dissection of that fish. So I will share you my screen and listen to what I have to tell you today. So this case 156, the polytheres Sinica.
Lenses with a bacterial infection.
And here we can have the books that tell you more about fish diseases. Also about very strange fish like polypterus and long nose elephant or cynodontes, so available for you when you shop for books. And here is the fish in the aquarium. Many are behaving very badly, becoming skinny.
You see, there's getting nervous swimming.
Some are laying on the bottom. You see one dead there on the side, this one weak one here, another thin one. They're not eating well, so they were suffering. So we had to examine the fish. And the first thing we found was in the gills, that there was a bacterial infection.
The gills, you can see here the.
Pattern bacteria and the lamella, which are completely devored by the bacteria.
So some necrosis in the gills, which.
Is of course all fish will die from that quickly.
We found a bad liver. You see the red patches, bleeding patches in the liver. And then we saw in the gut the intestine, air bubbles and a bleeding intestine with bleeding parts.
See, very bleedy.
That's not the normal our guts would look like.
And this gut seems to be obstructed.
By these gas bubbles.
And here we see the food sticking here and not be able to move out. So the air bubbles seems to cause a problem. And where did the air bubbles come from? Well, that can be gas formation from certain bacteria. So there might be a problem with the microbiome.
So our conclusion was bacterial infection.
Try to treat with an antibiotic. Advice you should get from your veterinarian.
Or your fish doctor. Check for the origin of the problem.
That might have been polluted.
Frozen or live fish food.
Yes, could be also frozen food.
I explained that in my videos about.
Bacterial effects in food.
Try to get pro and prebiotica in the food to improve the gut microbiome and to improve the immune system of.
This fish, together with the treatment, of course.
So my books can help you to understand fish diseases. I just continue to recommend them and.
Also to become a specialist in fish.

So I hope this specific case on.
A bacterial infection on polypterus helped you understand this kind of problems and how to treat.
