Potentially Parasite Deadly to Dogs Discovered in Colorado River, California

Researchers raised concerns about the health impacts of a deadly parasite or flatworm in the Colorado River and Southern California, which is deadly to dogs.

Dogs likely suffer from intestine and liver issues, urging pet owners to be careful, especially when traveling to the Colorado River with their pets. The research findings were published in Pathogens.

According to the study, infectious diseases can be harmful to animals, like dogs. With the exacerbating effects of climate change, researchers warned that it would help spread the pathogens, including parasites or the Heterobilharzia americana that was detected in the Colorado River.

As a result, monitoring efforts and surveillance are important to prevent the spread of infectious diseases that harm both animals and humans.

Potentially Parasite Deadly to Dogs

The parasite is mostly found in the Gulf Coast States, and other areas, including North Carolina, Kansas, and Indiana. The discovery of deadly diseases that can affect dogs' health can lead to canine schistosomiasis, urging pet owners to avoid bringing their pets while swimming in the Colorado River.

Immediately, researchers collected samples of 2,000 snails near the banks where potential infections occurred. The team was surprised after finding the snails associated with H. Americana, and the parasite is found in the area.

"It gets into the veins of the intestinal lining, and that's where it develops into an adult and mates. The presence of the adults in the veins isn't the problem," Adler Dillman, a UCR nematology professor, said, as quoted in the report.

The report warned that exposure to said parasites can be life-threatening to dogs. Limiting outdoor plans with your pets can minimize or avoid the risk of infection. It is also possible to be immersed in freshwater lakes where infection has been reported.

"It's the eggs that get into the lungs, spleen, liver, and heart. The immune system tries to deal with it, and hard clusters of immune cells called granulomas form. Eventually, the organ tissues stop functioning," Dillman said.

Infection Symptoms

According to the report, the symptoms can likely show within several months. When they are infected, the animal can show signs of infection, including the following:

Loss of appetite
Vomiting
Diarrhea
Liver disease
Weight loss

The researcher emphasizes that pet owners should consult a veterinarian for their pets, and undergo a fecal test. Early detection will help save a dog from death.

"Treatment typically involves the use of multiple medications and close monitoring of the dog by a veterinarian," Emily Beeler, a veterinarian from the Department of Public Health in Los Angeles County, explained, as quoted in the same report.

The parasite does not pose a threat to human health. People who swim in an infected area can likely experience a red rash and a swimmer's ear.
