, and are the most common spp. in chickens and have a confirmed or suggested zoonotic potential. No recent data are available on their prevalence and impact in the Belgian chicken industry or in the recreational chicken branch. Therefore, a cross-sectional epidemiological study was executed where samples were collected from both factory-farmed and backyard chickens. More specifically, pharyngeal chicken swabs were obtained from 20 chicken farms, 5 chicken abattoirs, and 38 different backyard locations and were analyzed using species-specific Polymerase Chain Reactions (PCRs) for the presence of the three avian spp. To investigate their zoonotic potential, samples were simultaneously collected from 54 backyard chicken caretakes and 37 professional chicken caretakers or abattoir employees and analyzed using species-specific PCRs as well. This study confirmed the presence of DNA of all three species in both the chicken industry and backyard settings. was the most prevalent in the industry chickens (11.0%), whereas was the dominant species in the backyard chickens (14.5%). infections were more common in the commercial chickens (9.0%) compared to the backyard chickens (2.6%). The DNA of all three species was also detected in humans (3.9% , 2.9% and 1.0% ).
[具体物种名称1]、[具体物种名称2]和[具体物种名称3]是鸡中最常见的[物种属名]物种，并且具有已确认或推测的人畜共患病潜力。目前尚无关于它们在比利时养鸡业或休闲养鸡领域的流行情况及影响的最新数据。因此，开展了一项横断面流行病学研究，从工厂化养殖鸡和后院鸡中采集样本。更具体地说，从20个养鸡场、5个鸡屠宰场和38个不同的后院地点采集鸡咽拭子，并使用针对这三种禽类[物种属名]物种的特异性聚合酶链反应（PCR）进行分析。为了调查它们的人畜共患病潜力，还同时从54名后院鸡饲养者以及37名专业养鸡饲养者或屠宰场员工中采集样本，并同样使用特异性PCR进行分析。这项研究证实了在养鸡业和后院环境中均存在所有三种[物种属名]物种的DNA。[具体物种名称1]在养殖鸡中最为普遍（11.0%），而[具体物种名称2]是后院鸡中的优势物种（14.5%）。与后院鸡（2.6%）相比，[具体物种名称3]感染在商业鸡中更为常见（9.0%）。在人类中也检测到了所有三种物种的DNA（[具体物种名称1]为3.9%，[具体物种名称2]为2.9%，[具体物种名称3]为1.0%）。
