Blue-crowned motmots remained persistently infected at other institutions despite several different treatment modalities.
Based on overrepresentation of blue-crowned motmots in reported cases, additional treatment options were investigated.
Based on observations during this study and communications with other affected institutions, passerine birds are considered high-risk species for air sac trematodiasis, and blue-crowned motmots are potential carriers for Szidatitrema species.
Samples from birds representing 27 species from 9 orders were evaluated: Bali mynah (Leucopsar rothschildi; n = 9), black-necked stilt (n = 2), blue-crowned laughing thrush (Dryonastes courtoisv, n = 4), blue-crowned motmot (Momotus momota; n = 2), blue-faced honeyeater (Entomyzon cyanotis; n = 4), blue-grey tanager (n = 5), Bourke's parrot (Neophema bourkir, n = 6), Cape thick-knee (Burhinus capensis; n = 1), crested wood partridge (Rollulus roulroul, n = 7), emerald starling (Lamprotornis iris', n = 3), fairy bluebird (n = 5), golden-breasted starling (?
