A take a look at the analysis findings
As the virus sometimes unfold by snails, the researchers gathered over 2,000 snails from the Colorado River’s banks and examined DNA to find out the presence of snails and flatworms.

Other than dogs, the parasite can infect different species, together with raccoons, marsh bunnies, horses, mountain lions, and opossums.
The parasite first enters dermis after which strikes to the lungs, the place it might probably trigger hemorrhage.
“The presence of the adults within the veins isn’t the issue. It’s the eggs that get into the lungs, spleen, liver, and coronary heart. The immune system tries to cope with it, and onerous clusters of immune cells referred to as granulomas kind. Eventually, the organ tissues cease functioning,” Dillman instructed UC Riverside News.
According to UC Riverside News, 11 dogs contracted the an infection in California counties and one in every of them has died since 2019.
Symptoms and therapy: Can parasite trigger an infection in people?
Emily Beeler, a veterinarian with the Los Angeles County Department of Public Health, said signs that sometimes seem step by step embody lack of urge for food, vomiting, diarrhea, vital weight reduction, and indicators of liver injury.
Beeler suggested that if any canine exhibits these signs then one ought to ask veterinarian for a easy fecal check. A veterinarian would use a number of drugs to deal with the canine by protecting the pet beneath shut monitoring.
