常见错误

❌ 错误:This disease is very pathogenic.
✓ 正确:This disease is caused by a pathogenic agent.

错误:'pathogenic' 通常描述微生物或物质具有致病性,而不是疾病本身。正确:应说明疾病是由致病因子引起的。

❌ 错误:He feels pathogenic after eating that food.
✓ 正确:He feels sick after eating that food, which may contain pathogenic bacteria.

错误:'pathogenic' 是形容词,不能直接描述人的感觉。正确:应使用 'sick' 等词描述不适,并说明可能涉及致病细菌。

近义词辨析

infectious

'infectious' 强调能够传播感染,通常指疾病或病原体通过接触等方式扩散;而 'pathogenic' 更侧重于具有引起疾病的能力,不一定涉及传播。

Influenza is highly infectious (容易传播), but not all infectious agents are pathogenic (some may not cause disease).

virulent

'virulent' 描述病原体的毒力或严重程度,强调致病的强烈或快速效应;'pathogenic' 更通用,指任何能致病的特性,不一定暗示高强度。

A virulent strain of bacteria causes severe symptoms quickly, whereas a pathogenic strain might cause mild or chronic disease.
