The dangers of the brain-eating amoeba Naegleria fowleri when travelling with a dog to endangered areas
Travelling with dogs offers many joys , but also carries risks. One serious danger is infection by the brain-eating amoeba Naegleria fowleri, which is found in warm freshwater areas.
This amoeba can affect both humans and animals and leads to an often fatal brain inflammation, primary amoebic meningoencephalitis (PAM).
What is Naegleria fowleri?
Naegleria fowleri is a thermophilic amoeba found in warm freshwater sources such as lakes, rivers and hot springs. It enters the body through the nose and travels along the olfactory nerve to the brain, where it causes severe damage.
Main distribution areas of Naegleria fowleri
Naegleria fowleri is mainly distributed in warm climates, especially in:
- Southern states of the USA : Texas, Florida
- Australia
- Other tropical and subtropical regions
Distribution of Naegleria fowleri in Europe
In addition to the main distribution areas, Naegleria fowleri has also been detected in rare cases in European countries, including:
- Spain
- Italy
- Great Britain
- Czech Republic
- France
Unfortunately, information about this is difficult to find and sometimes inaccurate or contradictory.
Transmission routes and risk for dogs
Dogs swimming or sniffing in warm waters could also become infected. The amoeba enters the dog’s body through the nose and causes a fatal infection of the brain, similar to what happens in humans.
Climate change and weather extremes
Climate change contributes to the spread of Naegleria fowleri. Extreme weather events such as floods and droughts change water conditions and can promote the growth of the amoeba.
Higher water temperatures and stagnant water after floods are particularly problematic and make increased spread in Europe more likely.
Progress in combating
An interesting development in the fight against Naegleria fowleri concerns the use of giant viruses. Scientists in Klosterneuburg have discovered that giant viruses may be able to help fight this parasite.
These viruses have proven effective in fighting parasites such as Naegleria fowleri.

Preventive measures
- Avoid warm, stagnant water : You should avoid such areas, especially during the summer months.
- Choose safe swimming spots : Only use bodies of water that are considered safe by locals.
- Regular health checks : Visit your veterinarian, especially after traveling to high-risk areas.
Symptoms and treatment of Naegleria Fowleri in dogs
Symptoms in infected dogs may include behavioral changes, disorientation, and seizures. Due to the rapid progression and rarity of the infection, treatment is difficult and often unsuccessful.
Infection by Naegleria fowleri is a rare but serious danger for dogs. By taking specific precautions and being aware of the risks, dog owners can minimize the risk of infection and continue to enjoy carefree outdoor activities.
