Giardia parasite found in 6.3% of cat samples tested in North America

Giardia parasite found in 6.3% of cat samples tested in North America

Researchers tested more than 157,000 stool samples from domestic cats in 49 US states and five Canadian provinces for the parasite Giardia duodenalis.

They found the parasite in 6.3% of samples, and 18.5% of infected cats carried strains that may also infect people.

The parasite can cause giardiasis, an intestinal illness also known as “beaver fever.”

People most often get infected through contaminated water or food, but close contact with infected animal or human feces can also spread it.

Many people with healthy immune systems clear the infection within weeks, though severe cases can cause lasting symptoms, and people with weakened immune systems face greater risks.

Kittens tested positive more often than older cats, and male cats more often than females.

The researchers recommend regular stool tests for cats to help detect infections early.
