How long do pet cichlids live?

Can fish TB survive outside of the aquarium?

The bacterium that causes fish TB can survive for long periods of time outside aquatic organisms. In fact, it has been known to be able to live in water and moist environments without a population of fish present at all!

What is fish tuberculosis?

“Fish tuberculosis” is the common name for a fish infected with Mycobacterium spp. This bacterial genus has a unique outer protective coating that makes it impossible to treat once it is inside your system.

What causes tuberculosis in fish?

Tuberculosis in fish is a contagious disease that can occur in aquarium fish and is caused by Mycobacterium Marium. You can diagnose Fish TB by observing signs and symptoms such as multiple granulomas in visceral organs, wasting, ulcers, greyish-white nodules, and dropsy eyes.

What are the symptoms of fish TB?

Because the mycobacterium invades all the organs in a fish’s body, including the skin, the symptoms of fish TB can mimic many other diseases and are often difficult to pin down. The one common thread is that they occur SLOWLY in most cases. An ulcer which slowly erupts over a span of weeks is probably fish TB.

What is the treatment for fish tuberculosis?

There is no effective treatment of fish tuberculosis other than supportive care. Some fish can live for a long time with an infection and show no outward clinical signs of disease. You may see a long-term pattern of random deaths with no links to other diseases, fish additions, diet or other environmental causes, such as water quality.

Is fish TB contagious?

Fish TB is highly contagious and can be transmitted by fomite (inanimate objects). This bacteria is likely to be lurking in your aquarium water without anyone noticing.

How do fish get infected with diseases?

Usually, fish get infected by eating other dead fish who have been infected. They can also get infected from eating infected organisms. With regard to humans, they usually get infected by large amounts of mycobacteria gaining access to the body through an open wound.

What is fish tuberculosis (mycobacteriosis)?

The proper name for this condition affecting fish is mycobacteriosis. “Fish tuberculosis” is a term that’s commonly used to describe this fish disease because the clinical signs are similar to tuberculosis disease in humans, but sticklers for accuracy will opt for the term “mycobacteriosis” instead.

What is fish tuberculosis and how is it spread?

Some species will cause a localized infection, while others cause a full-body systemic disease. The disease is referred to as “fish Tuberculosis” since the Mycobacterium that causes it is the cause for this infection in humans as well. Fish Tuberculosis is also referred to as an acid-fast disease, granuloma disease, or piscine tuberculosis.

Should I depopulate my fish tank for TB infection?

A good idea as a hobbyist or pet store employee is to take precautions when it comes to handling, adding, or removing fish from a specific reservoir. If you do, however, have a serious fish TB infection in your tank, the best advice is depopulation of the entire tank.

What is Mycobacterium and why is my fish sick?

The culprit behind this sickness is mycobacterium, a type of gram negative bacteria that is found in most aquariums. Under normal, optimal conditions, this bacteria does not attack ornamental freshwater fish.

What is fish tuberculosis (tuberculosis)?

The disease is referred to as “fish Tuberculosis” since the Mycobacterium that causes it is the cause for this infection in humans as well. Fish Tuberculosis is also referred to as an acid-fast disease, granuloma disease, or piscine tuberculosis.

Can fish tuberculosis survive in water?

Fish Tuberculosis. It can also spread to other animals and is capable of surviving in both soil and water without any host for prolonged periods of time. Don’t be fooled by the word “marinum” – this nasty little organism will survive just as well in freshwater conditions.

Can fish get tuberculosis?

Tuberculosis is a very important disease of humans and mammals, but fish do not get tuberculosis. All fish are susceptible to mycobacteriosis, though some species seem to be at greater risk than others. The disease has been reported in a broad range of fish species from freshwater, marine and brackish water environ- ments.

What is fish TB called?

Fish TB ravages an aquarium and causes persistent skin infections in humans. When it blooms in a person, it’s also called “Aquarium Granuloma” or “Fish Tank Granuloma.”

Can fish TB be transmitted to humans?

As it can be transmitted to humans, if you suspect fish TB in your aquarium, ensure that you wear full length gloves (make sure the water can’t get in), mask, goggles and cover any abrasions with a suitable dressing in order to protect yourself.

What is fish TB?

Diana Walstad (an incredibly knowledgeable scientist and author of “Ecology of the Planted Aquarium”, a book which is must reading for any serious planted tank hobbyist) has described fish TB as “ the most prevalent disease in the aquarium hobby ” (“Fish TB”, Diana Walstad, Tropical Fish Magazine, June 2007 issue, pp. 36-41).

Is interrupted treatment for TB safe for fish?

Interrupted treatment can result in immunity against medication and, unfortunately, there’s also a strain of TB that’s naturally resistant to drugs. The highly infectious tuberculosis that remains an epidemic in many countries is not the same thing that affects fish.

Is there TB in my Aquarium water?

This bacteria is likely to be lurking in your aquarium water without anyone noticing. This bacteria easily lives in the soil and substrate of infected aquariums. Fish TB is closely related to the tuberculosis bacteria. However, it is fortunately not the same and has not shown respiratory symptoms in humans.

How do you get rid of fish tuberculosis?

A lot of aquarium problems can be fixed by performing frequent water changes, increasing the water temperature and adding some salt to the water, but fish tuberculosis is not one of them. Raising the water temperature may even worsen the problem since Mycobacterium marinum prefers warm water (their ideal temperature is 30°C).

What is the best temperature for TB in fish?

It is believed fish TB multiplies in temperatures of 18-42°C (64.4-107.6°F), which would indicate raising the temperature would not disrupt this bacteria’s behaviour in a stocked aquarium. It is also not affected by salt levels, and it can infect marine aquariums, so adding salt will not address the issue.

How common is TB in cattle?

Very few cases of TB are reported in cattle. This is possibly because the symptoms are very similar to other respiratory diseases but also because regular TB testing catches the infection long before it becomes a chronic disease visually affecting the animal.

What happens if a cow has tuberculosis?

TB lesions can grow in parts of the body other than the lungs, including the digestive tract, udder and liver. If these lesions open M.bovis can be shed in the milk (which would put suckling calves at risk) and urine/faeces.

Can you get TB from a wild deer?

Most cases of bovine Tb in humans are caused by consuming unpasteurized dairy products and the likelihood of contracting bovine Tb from a wild deer is minuscule. There has been only one confirmed case of transmission of bovine Tb to a human from an infected white-tailed deer.
