A controlled, replicated study from 1992-1999 on Ile aux Aigrettes, Mauritius (Swinnerton et al. 2005) found that pink pigeon Nesoenas mayeri (formerly Columba mayeri) chicks with suspected trichomoniasis Trichomonas gallinae had significantly higher survival if treated with carnidazole compared with untreated chicks showing symptoms (54% survival for 89 treated chicks vs. 0% survival for 19 untreated). Across both symptomatic and asymptomatic chicks, treated chicks had higher survival rates than untreated chicks (62% survival of 129 treated vs. 27% of 123 untreated). However, treatment did not affect subsequent juvenile survival up to 150 days old. Across sites on both the island and mainland Mauritius, survival of treated birds (both juveniles and adults) was significantly higher than untreated birds (74% survival of 19 treated birds vs. 25% survival for 24 untreated). Providing medicated water to all individuals on Ile aux Aigrettes did not reduce the incidence of trichononiasis in the subpopulation, with birds becoming re-infected after treatment stopped.
