Trichomonas gallinae infections in the ringdove (Streptopelia risoria).
Twenty Trichomonas-free ringdoves (Streptopelia risoria) were intubated with Trichomonas gallinae derived from pigeons (Columba livia). By 15 days post-intubation (DPI) five doves had T. gallinae-type lesions (Cankers) in the pregastric portion of the digestive system, and six doves had T. gallinae present without lesions. Sixteen Trichomonas-free ring doves were infected using T. gallinae from axenic cultures. By 21 DPI four doves had T. gallinae lesions and died, and one dove had T. gallinae present without lesions. This is the first report of T. gallinae lesions in ring doves since Cauthen reported it in 1936.
