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.
将来自家鸽（Columba livia）的鸡三毛滴虫接种到20只无滴虫的环颈鸽（Streptopelia risoria）体内。插管后15天（DPI），5只鸽子在消化系统的前胃部分出现了鸡三毛滴虫型病变（溃疡），6只鸽子体内有鸡三毛滴虫但无病变。使用来自无菌培养物的鸡三毛滴虫感染了16只无滴虫的环颈鸽。到21 DPI时，4只鸽子出现鸡三毛滴虫病变并死亡，1只鸽子体内有鸡三毛滴虫但无病变。这是自1936年考森报道以来，环颈鸽中鸡三毛滴虫病变的首次报告。
