Abstract

Two interferon-inducing polycarboxylates were tested for antiviral activity on foot-and-mouth disease (FMD) virus infections in mice, guinea pigs, and swine. Polyacrylic acid, given intraperitoneally, had a protective effect on infection by FMD virus administered in the peritoneal cavity of mice and in the foot pad of guinea pigs. Chlorite-oxidized oxyamylose (COAM) was effective in mice at a dosage of 2 mg/kg. Swine were not protected against naturally transmitted FMD by 120 mg/kg of COAM nor by polyacrylic acid. Swine were not totally unresponsive to COAM since it delayed symptoms of hog cholera. Interferon was not detected in the serum of COAM-treated swine. With FMD virus, an example was found of activity of interferon inducers in experimental hosts and lack of activity in a natural host.

摘要

测试了两种干扰素诱导性多羧酸盐对小鼠、豚鼠和猪口蹄疫(FMD)病毒感染的抗病毒活性。腹腔注射的聚丙烯酸对在小鼠腹腔和豚鼠脚垫中接种的口蹄疫病毒感染具有保护作用。亚氯酸盐氧化直链淀粉(COAM)在剂量为2mg/kg时对小鼠有效。120mg/kg的COAM和聚丙烯酸均不能保护猪免受自然传播的口蹄疫感染。猪对COAM并非完全无反应,因为它能延迟猪霍乱的症状。在接受COAM治疗的猪血清中未检测到干扰素。对于口蹄疫病毒,发现了干扰素诱导剂在实验宿主中有活性而在自然宿主中无活性的一个例子。
