In this study, the ability of oyster larvae, brooded in the pallial cavity of the parent oyster, to become infected in the pallial fluid, which is influenced by the brooding oyster and surrounding environment, was investigated. Larvae were collected over three summers from three areas around Ireland. Samples were screened for the presence of Bonamia ostreae DNA using PCR analysis. Four samples of larvae were found to be positive for B. ostreae DNA, though the parent oysters were negative for infection. Larvae may be able to acquire the pathogen from the water column during filter feeding or elimination of pseudo-faeces by the brooding adult.
在本研究中，对在亲代牡蛎外套腔中育成的牡蛎幼虫在受育成牡蛎和周围环境影响的外套液中被感染的能力进行了调查。在三个夏天从爱尔兰周边三个地区采集了幼虫。使用聚合酶链反应（PCR）分析筛选样本中是否存在奥氏博纳米虫（Bonamia ostreae）DNA。发现四份幼虫样本的奥氏博纳米虫DNA呈阳性，尽管亲代牡蛎的感染检测为阴性。幼虫可能在滤食过程中从水柱中获取病原体，或者由育成的成体排出假粪便时感染。
