Malnourished B.C. orca might have parasite that can be treated

An emaciated killer whale, which has been the focus of joint Canada-U.S. rescue efforts, might have a common parasite that can be treated with antibiotics and a de-worming medication, officials say.
The three-year-old whale, known as J50 or Scarlet, has been under scrutiny since June when researchers noticed that she appeared malnourished.
Last week, the team obtained a fecal sample from the water where she was swimming with her mother and a sibling.
