oncogenic virus

Human papillomavirus is an oncogenic DNA virus and has more than 90 subtypes. High risk types ( HPV 16, 18, 33) are associated with many kinds of malignant neoplasms of head and neck.

人乳头状瘤病毒是一种致瘤性DNA病毒，在其90个亚型中以高危型HPV16，HPV18，HPV33等与人类头颈部恶性肿瘤关系密切。

Human papillomaviruses ( HPVs and herpes simplex virus type 2 ( HSV-2), both of which are oncogenic DNA viruses spread primarily by sexual contact, are closely associated with human cervical cancer.

人乳头瘤病毒（HPV）和人单纯疱疹病毒Ⅱ型（HSV-2）是与宫颈癌密切相关的丙种性传播DNA肿瘤病毒。二者皆可感染宫颈鳞状上皮细胞。

The results indicated that there was no oncogene in L783-MuLV genome, L783-MuLV belonged to slow oncogenic virus.

这说明，L783小鼠白血病病毒基因组中不含有致癌病毒基因，此病毒属于慢性致瘤性逆转录病毒。

They are oncogenic DNA virus with icosahedral capsids 40 nm~ 45 nm in diameter, containing three to four viral proteins and double strand, covalently closed, circular genomes approximately 5 000 bp in size.

病毒无囊膜，直径40nm～45nm，有3种～4种衣壳蛋白，基因组为约5000对核苷酸组成的双链闭合环状DNA。

He assumed that the tumour cells, if they contained an oncogenic virus, should harbour viral DNA integrated into their genomes.

他认为，肿瘤细胞，如果它们载有致癌病毒，应港湾病毒DNA整合到它们的基因组。
