A small scale serological survey for antibodies to maedi-visna virus among 13 flocks of sheep in Morocco revealed the infection in one flock. Infection appeared to be related with imported sheep. In addition, two abattoir surveys yielded, 0.1% lungs with gross and histological lesions suggestive of maedi.
在摩洛哥对13群绵羊进行的一项小规模梅迪-维斯纳病毒抗体血清学调查显示,其中一群羊受到感染。感染似乎与进口绵羊有关。此外,两项屠宰场调查发现,0.1%的肺脏有肉眼可见和组织学病变,提示患有梅迪病。
