Abstract
Frogs and tadpoles were captured at 14 sites in and near Minnesota during 1978-1979 and nearly all appeared healthy. A. hydrophila was isolated from 94 of 294 (32%) juvenile and adult frogs and from 66 of 104 (63%) tadpoles. Of the isolates from frogs and tadpoles, respectively, 68 and 47% were from the intestine only, 12 and 32% were from the intestine and other sites and 20 and 21% were from extraintestinal sites only. Isolations were more frequent from frogs collected in March-June than in Aug.-Nov. Evidence was not found that disease due to A. hydrophila was a primary cause of declining R. pipiens populations in Minnesota.
