Abstract

ABSTRACT Disseminated neoplasia is reported for the first time in Ameghinomya antiqua (Veneridae) from Chile on the southeastern Pacific coast. A total of 710 clams were collected in winter 2019 and summer 2021 from five sites in three regions: Coquimbo, Biobio, and Los Lagos; all clams were processed by histology. The disease was only detected in clams from the Biobío region. It was characterized by the presence of numerous neoplastic cells with enlarged nuclei and high nuclear to cytoplasmic volume ratios and the almost absence of normal hemocytes. The prevalence did not vary between seasons (7% in winter and 9% in summer).

智利古老Venerid Clam Ameghinomya中的播散性肿瘤

摘要首次报道了太平洋东南海岸智利Ameghinomya antiqua (Veneridae)的播散性肿瘤。2019年冬季和2021年夏季，从三个地区的五个地点共收集了710只蛤蜊:科金博、比奥比奥和洛斯拉各斯;所有蛤蜊均经组织学处理。这种疾病只在Biobío地区的蛤蜊中发现。其特征是存在大量的肿瘤细胞，细胞核增大，核与细胞质体积比高，几乎没有正常的血细胞。发病率在季节之间没有变化(冬季为7%，夏季为9%)。
