Family consists of small, non-enveloped viruses with linear, single-stranded DNA genomes of approximately 4-6 kilobases, subdivided into three subfamilies, , and , and unassigned genus . Parvoviruses of aquatic animals infect crustaceans, mollusks, and finfish. This review describes these parvoviruses, which are highly host-specific and associated with mass morbidity and mortality in both farmed and wild aquatic animals. They include Cherax quadricarinatus densovirus (CqDV) in freshwater crayfish in Queensland, Australia; sea star-associated densovirus (SSaDV) in sunflower sea star on the Northeastern Pacific Coast; Clinch densovirus 1 in freshwater mussels in the Clinch River, Virginia, and Tennessee, USA, in subfamily ; hepatopancreatic parvovirus (HPV) and infectious hypodermal and hematopoietic necrosis virus (IHHNV) in farmed shrimp worldwide; in gulf pipefish in the Gulf of Mexico and parts of South America; tilapia parvovirus (TiPV) in farmed tilapia in China, Thailand, and India, in the subfamily ; and metallodensovirus (PmMDV) in Vietnamese , in unassigned genus . Also included in the family are novel parvoviruses detected in both diseased and healthy animals using metagenomic sequencing, such as zander parvovirus from zander in Hungary and salmon parvovirus from sockeye salmon smolts in British Columbia, Canada.
细小病毒科由小型、无包膜的病毒组成,其基因组为线性单链DNA,大小约为4 - 6千碱基,细分为三个亚科,即浓核病毒亚科、小病毒亚科和未分类属。水生动物细小病毒可感染甲壳类动物、软体动物和硬骨鱼。本综述描述了这些细小病毒,它们具有高度的宿主特异性,与养殖和野生水生动物的大规模发病和死亡有关。其中包括澳大利亚昆士兰州淡水小龙虾中的四脊滑螯虾浓核病毒(CqDV);东北太平洋沿岸向日葵海星中的海星相关浓核病毒(SSaDV);美国弗吉尼亚州和田纳西州克林奇河淡水贻贝中的克林奇浓核病毒1,属于浓核病毒亚科;全球养殖虾中的肝胰腺细小病毒(HPV)和传染性皮下及造血组织坏死病毒(IHHNV);墨西哥湾和南美洲部分地区海湾管鱼中的[未提及具体名称的病毒];中国、泰国和印度养殖罗非鱼中的罗非鱼细小病毒(TiPV),属于小病毒亚科;越南[未提及具体名称的动物]中的[未提及具体名称的金属浓核病毒](PmMDV),属于未分类属。细小病毒科还包括通过宏基因组测序在患病和健康动物中检测到的新型细小病毒,如匈牙利梭鲈中的梭鲈细小病毒和加拿大不列颠哥伦比亚省红大麻哈鱼幼鱼中的鲑鱼细小病毒。
