A uncommon and unusually highly effective pressure of a parasite generally present in cat feces killed 4 otters on the California coast, a discovering researchers described Wednesday as unprecedented and probably harmful to people and different animals.
Karen Shapiro, an affiliate professor of pathology, microbiology and immunology on the College of California, Davis, described the preliminary findings in a information launch as a “full shock” and stated the uncommon pressure of the parasite, generally known as Toxoplasma gondii, has by no means earlier than been seen in sea otters or every other aquatic mammal or hen.
Shapiro and three co-authors from the college and the California Division of Fish and Wildlife revealed their analysis Wednesday within the journal Frontiers in Marine Science.
Melissa Miller-Henson of the Fish and Wildlife Division stated within the launch that she has studied the toxoplasmosis in sea otters for 25 years and has by no means seen such extreme lesions or excessive numbers of parasites.
