The prevalence of antibodies to orthopoxvirus in 217 sera collected from domestic cats in the western part of Norway was 10.1 per cent as measured by a competitive ELISA. In one of the seropositive cats antibodies were also detected by an immunofluorescence assay. The average age of the cats sampled was 4.9 years, but the average age of the seropositive individuals was 7.3 years, higher than the average age of clinical cowpox virus cases in Britain (4.2 years), and in Germany (3.9 years). Antibodies against feline immunodeficiency virus (FIV) were detected in nine of 30 (30 per cent) of the seropositive cats, and in five of 30 (17 per cent) of the seronegative cats, which suggests that FIV infection may influence the susceptibility of domestic cats to orthopoxvirus, or vice versa. Orthopoxvirus infections, have recently been detected in rodent populations in several areas of Norway, and the infection may therefore be present in cats all over the country; cat owners and animal handlers should be aware of this (re)emerging zoonosis.
通过竞争ELISA检测，从挪威西部家猫采集的217份血清中，正痘病毒抗体的流行率为10.1%。在一只血清阳性猫中，还通过免疫荧光试验检测到了抗体。采样猫的平均年龄为4.9岁，但血清阳性个体的平均年龄为7.3岁，高于英国临床牛痘病毒病例的平均年龄（4.2岁）和德国的平均年龄（3.9岁）。在30只血清阳性猫中有9只（30%）检测到抗猫免疫缺陷病毒（FIV）抗体，在30只血清阴性猫中有5只（17%）检测到该抗体，这表明FIV感染可能会影响家猫对正痘病毒的易感性，反之亦然。最近在挪威几个地区的啮齿动物种群中检测到正痘病毒感染，因此该国各地的猫可能都存在这种感染；猫主人和动物处理人员应意识到这种（再）出现的人畜共患病。
