A feline immunodeficiency virus-like virus (FIV-Oma) isolated from a Pallas' cat (Otocolobus manul) is highly cytopathic in CrFK cells, in contrast to the chronic, noncytolytic infection established by an FIV isolate from a domestic cat (FIV-Fca). The virions have typical lentivirus morphology, density, and magnesium-dependent reverse transcriptase activity. The major core protein is antigenically cross-reactive with that of FIV-Fca; however, FIV-Oma transcripts do not cross-hybridize with FIV-Fca. A conserved region of the FIV-Oma pol gene has 76 to 80% nucleic acid identify with the corresponding pol regions of other feline lentiviruses and 64 to 69% identity with those of human, ovine, and equine lentiviruses.
从兔狲(Otocolobus manul)分离出的一种猫免疫缺陷病毒样病毒(FIV - Oma)在CrFK细胞中具有高度细胞病变性,这与从家猫分离出的FIV毒株(FIV - Fca)所建立的慢性、非细胞溶解性感染形成对比。这些病毒粒子具有典型的慢病毒形态、密度和镁依赖性逆转录酶活性。主要核心蛋白与FIV - Fca的核心蛋白具有抗原交叉反应性;然而,FIV - Oma转录本与FIV - Fca不发生交叉杂交。FIV - Oma pol基因的一个保守区域与其他猫慢病毒的相应pol区域具有76%至80%的核酸同一性,与人类、绵羊和马慢病毒的相应区域具有64%至69%的同一性。
