Ten pregnant buffalo cows, six of which were subsequently shown to be carriers of SAT 1, 2 and 3 viruses, were captured in the Kruger National Park (KNP) and allowed to calve in captivity. The buffalo cows and calves were separated by a fence from 6 FMD susceptible cattle but the buffalo and cattle were obliged to use common drinking troughs and hay racks. Over a period of 15 months, during which the buffalo calves lost their maternally-derived immunity, neither the buffalo calves nor the susceptible cattle became infected with FMD virus. By the end of the observation period, however, only 1 buffalo cow still had detectable virus in its oesophageal/pharyngeal specimens.
十头怀孕的水牛母牛在克鲁格国家公园（KNP）被捕获，其中六头随后被证明是南非1型、2型和3型病毒的携带者，并被圈养至产犊。水牛母牛和小牛与6头易感染口蹄疫的牛被围栏隔开，但水牛和牛必须共用饮水槽和干草架。在15个月的时间里，在此期间水牛小牛失去了母源免疫力，但水牛小牛和易感牛均未感染口蹄疫病毒。然而，到观察期结束时，只有1头水牛母牛的食管/咽部分标本中仍可检测到病毒。
