The influenza A virus [A/Chicken/Pennsylvania/1370/83 (H5N2)] that caused up to 80% mortality among chickens provided a model system for testing the efficacy of chemotherapeutic agents against highly virulent influenza virus. Amantadine and rimantadine administered in drinking water were efficacious both prophylactically and therapeutically. However, under conditions simulating natural transmission of virus, amantadine- and rimantadine-resistant viruses arose and were transmitted to other birds in contact with the infected chickens, causing mortality. Simultaneous administration of inactivated H5N2 vaccine and amantadine provided protection. Thus, chemotherapy may be useful in the treatment of a highly pathogenic influenza virus outbreak in humans or other animals when used in combination with vaccine.
甲型流感病毒[A/鸡/宾夕法尼亚/1370/83(H5N2)]在鸡群中造成了高达80%的死亡率,为测试化学治疗剂对抗高致病性流感病毒的疗效提供了一个模型系统。通过饮水给予金刚烷胺和金刚乙胺在预防和治疗方面均有效。然而,在模拟病毒自然传播的条件下,出现了对金刚烷胺和金刚乙胺耐药的病毒,并传播给了与感染鸡接触的其他禽类,导致死亡。同时接种灭活H5N2疫苗和金刚烷胺可提供保护。因此,化学疗法与疫苗联合使用时,可能对治疗人类或其他动物的高致病性流感病毒爆发有用。
