Survey of Ranavirus and in Introduced Frogs in Hawaii, USA.

Ranaviruses and the fungus are globally important agents of emerging infectious amphibian diseases. Amphibians on Oahu, the Hawaiian Island with the greatest potential for disease introduction through the movement of goods and people, have never been surveyed for ranaviruses or . We surveyed all five species of frogs on Oahu, Hawaii, US for these pathogens. Of 325 individuals sampled from six sites, none were positive for ranavirus. However, we found in a total of four individuals of three species, the cane toad (), the American bullfrog (), and the greenhouse frog (), but not in the green and black poison dart frog () or the Japanese wrinkled frog (). The apparent lack of ranavirus and low prevalence of are noteworthy given how widespread these pathogens are in terms of both global distribution and host range. Surveillance should continue to document any changes in prevalence or the arrival of ranaviruses in Hawaii.
