Tested was the effect of the iodoform preparation iosan and the quaternary ammonium preparation bradofen against the viruses of the Newcastle disease (strain La Sota), laryngotracheitis (strain TsNIIP) and fowl pox (strain FK) in birds. The following results were obtained: 1. To a concentration of 3% (262 ppm of active iodine) and exposure of 45 min. to iosan the virus of laryngotracheitis was sensitive; that of Newcastle disease perished at a conc. of 5% (525 ppm of active iodine for 15 min); and that of fowl pox was not inactivated at a 30 min. exposure to a conc. of 7% (875 ppm of active iodine.) 2. Bradofen inactivated the Newcastle disease virus in a conc. of 0.5 per cent for 30 min., while the pox virus withstood a conc. of 1.5% up to the 30 th min. The virus of laryngotracheitis was inactivated by a conc. of 2 per cent for 45 min. The disinfection effect of the tested preparations was assessed as satisfactory.
测试了碘仿制剂碘散和季铵制剂布拉德芬对鸡新城疫病毒（La Sota株）、喉气管炎病毒（TsNIIP株）和鸡痘病毒（FK株）的作用。获得了以下结果：1. 对于碘散，当浓度为3%（活性碘262 ppm）并暴露45分钟时，喉气管炎病毒敏感；新城疫病毒在浓度为5%（活性碘525 ppm）时暴露15分钟会死亡；而鸡痘病毒在浓度为7%（活性碘875 ppm）暴露30分钟时未被灭活。2. 布拉德芬在浓度为0.5%时30分钟可灭活新城疫病毒，而痘病毒在浓度为1.5%时30分钟仍能耐受。喉气管炎病毒在浓度为2%时45分钟可被灭活。所测试制剂的消毒效果被评定为令人满意。
