Dual parasitic infections deadly to marine mammals – 1
Narrator: This is NIH Health Matters. I’m Joe Balintfy. A study of marine mammals that died the Pacific Northwest has shown an association between severe illness and co-infection with two kinds of parasites. NIH investigator Dr. Michael Grigg says, what’s surprising is that the two parasites are normally found in land mammals.
Grigg: One of them is toxoplasma which is a parasite that's common to cats and the other is sarcocystis which is common to opossums.
Narrator: Dr. Grigg theorizes that the parasites are getting into soil; and then, seasonal rainfall washes them into waterways where they ultimately get eaten by the marine mammals.
