Esophageal trichomoniasis has been rarely reported in chickens. At the California Veterinary Diagnostic Laboratory System-Turlock Branch, this disease was recently diagnosed in two cases submitted from backyard chicken flocks. The esophageal lesions observed were similar to those seen in several other important diseases of chickens. The causative trichomonad organisms were readily demonstrated on wet smears and by histologic studies. In both cases, the investigated flocks were afflicted with several concurrent diseases. California has experienced an increase in the number of small nontraditional chicken production operations. These facilities are sometimes in close proximity to commercial poultry operations and biosecurity barriers occasionally fail. The poor husbandry practices often used in these small flocks make them a potential reservoir for rare diseases such as trichomoniasis and also for disease organisms that are devastating to commercial poultry.
鸡食管毛滴虫病在鸡中鲜有报道。在加利福尼亚兽医诊断实验室系统 - 特洛克分部，最近从后院鸡群送来的两例病例中诊断出了这种疾病。观察到的食管病变与鸡的其他几种重要疾病中所见的病变相似。在湿涂片和组织学研究中很容易证实致病的毛滴虫生物体。在这两例中，所调查的鸡群都患有几种并发疾病。加利福尼亚小型非传统养鸡场的数量有所增加。这些养殖场有时与商业家禽养殖场距离很近，生物安全屏障偶尔会失效。这些小群鸡常常采用的粗放养殖方式使它们成为毛滴虫病等罕见疾病以及对商业家禽具有毁灭性的病原体的潜在宿主。
