  3. 3. A few cases of infection with M. ozzardi were found in the Chagres River valley, Panama, but all of these were recent arrivals from the Atrato River valley, Colombia.
  4. 4. No evidence was found that M. ozzardi is pathogenic or in any way a significant problem of public health importance.
  5. 5. Southeastern Panama is an endemic center of infection with M. ozzardi heretofore unknown in the geographical distribution of the parasite.
