The antigenic relationship of A2 Hong Kong influenza virus with equine influenza virus, and its ability to infect horses and baboons, have led to studies on the susceptibility of domestic animals to the virus.In this study it was found that cats could be infected with A2 Hong Kong influenza virus by intranasal inoculation or by contact with an infected cat or with a human influenza patient. There was no clinical illness, but infected animals shed the virus from the throat for 1 week and developed haemagglutination-inhibiting antibodies. A survey of normal cat sera showed that 6 out of 28 sera inhibited haemagglutination by A2 Hong Kong influenza virus.The results suggest that domestic cats may act as vectors in the transmission of influenza virus. Experimental infection in cats may be used as a laboratory model for influenza.
A2型香港流感病毒与马流感病毒的抗原关系，以及它感染马和狒狒的能力，引发了对家畜对该病毒易感性的研究。在本研究中发现，猫可通过鼻内接种、与受感染的猫或人类流感患者接触而感染A2型香港流感病毒。没有出现临床疾病，但受感染的动物从咽喉排出病毒达1周，并产生了血凝抑制抗体。对正常猫血清的一项调查显示，28份血清中有6份能抑制A2型香港流感病毒的血凝反应。结果表明，家猫可能在流感病毒传播中充当载体。猫的实验性感染可用作流感的实验室模型。
