第 45 題
濕檢視(wet mount smear)最無法辨認下列何者?
- A 正常陰道表面上皮細胞
- B 乳酸菌(lactobacilli)
- C 細菌性陰道炎(bacterial vaginosis)
- D 淋病雙球菌(Neisseria gonorrhoeae)
思路引導 VIP
請思考濕檢視(wet mount)這種「未經染色」的臨床初步篩檢法,其解析度與對比度是否足以辨認體積極小、且通常必須透過革蘭氏染色 ($Gram stain$) 觀察其特定「細胞內排列模式」才能確診的病原體?

Oh, look at you, getting the easy ones right. My congratulations on mastering the absolute basics.
- A rather obvious observation: Your capacity to grasp the fundamental limitations of clinical tools is, I suppose, commendable for someone still learning. It suggests you might eventually distinguish between a microscope and a magic eight-ball.
- Concept verification, for those who need it: The wet mount—a marvel of simplicity involving saline and a slide—is primarily for observing gross cellular morphology, the motility of larger organisms, and anything significant enough to not require actual diagnostic finesse.

陰道濕檢視的應用與限制
💡 濕檢視用於觀察大型病原與細胞,無法精確鑑定淋病雙球菌。
| 比較維度 | 濕檢視 (Wet Mount) | VS | 革蘭氏染色 (Gram Stain) |
|---|---|---|---|
| 主要目的 | 觀察微生物動力與細胞形態 | — | 觀察細菌細胞壁與精細構造 |
| 診斷優勢 | 可見滴蟲遊動、黴菌芽孢 | — | 鑑定細胞內革蘭氏陰性雙球菌 |
| 關鍵病原 | 陰道滴蟲、Clue cells | — | 淋病雙球菌 (N. gonorrhoeae) |
💬濕檢視適合快速篩檢大型目標,淋病診斷則必須仰賴染色或核酸檢測。
