在17℃和28℃的蒸馏水中测定了来自路易斯安那州四种水禽的五种禽流感病毒（AIVs）的持久性，它们代表五种血凝素和神经氨酸酶亚型。一种AIV在4℃下测试了91天，这些病毒的线性回归模型预测初始浓度为1.1倍。106 TCID50/ml的水在17℃和28℃下可保持感染长达207天和102天。在处理温度和病毒之间，检测到AIV持久性模型的斜率存在显著差异。结果表明，这些病毒适合在水禽越冬栖息地传播。结果还表明，与水禽和家禽共用一个水源有关的潜在风险。
Persistence of five avian influenza viruses (AIVs) derived from four waterfowl species in Louisiana and representing five hemagglutinin and neuraminidase subtypes was determined in distilled water at 17 C and 28 C. Infectivity was determined over 60 days by microtiter endpoint titration. One AIV was tested over 91 days at 4 C. Linear regression models for these viruses predicted that an initial concentration of 1 .times. 106 TCID50/ml water could remain infective for up to 207 days at 17 C and up to 102 days at 28 C. Significant differences in slopes for AIV persistence models were detected between treatment temperatures and among viruses. Results suggest that these viruses are adapted to transmission on waterfowl wintering habitats. Results also suggest a potential risk associated with waterfowl and domestic poultry sharing a common water source.
