（Ａ）幾乎無全身性症狀發生-正確
分泌物的量是不定的，但在發情時子宮頸會擴張並且有大量陰道粘液會增加。 受影響的奶牛沒有表現出任何全身性疾病的跡象。
The volume of the discharge is vari- able but frequently increases at the time of oestrus when the cervix dilates and there is copious vaginal mucus. Affected cows do not show any signs of systemic illness.



（Ｂ）是世界性問題，發生率為3.7-26.9％-正確
一項涉及 63 個牛群 (1989-1990) 的 20000 頭奶牛研究中記錄了 15% 有外陰分泌物的奶牛的平均發生率。 最低和最高四分位數值分別為 3.7% 和 26.9% (Esslemont & SpilKer 1992)。

A funher study involving 20000 cows in 63 herds (1989-1990) recorded a mean incidence of 15% ofcows having a vulval discharge. The lowest and highest quartile values were 3.7% and 26.9%, respectively (Esslemont & SpilKer 1992). 


（Ｃ）直腸檢查子宮呈鬆弛狀態-正確
直腸觸診經常顯示子宮復舊不良，有一種“麵團狀”的感覺。
Rectal palpation frequently shows a poorly involuted uterus, which has a 'doughy' feel.


（Ｄ）投予磺胺劑或見大黴素（gentamicin）之療效佳-錯誤
有幾種抗生素是不合適的。
Nitrofurazone具有刺激性，對生育能力有不利影響。
Aminoglycosides藥物在受感染子宮中在厭氧環境中無效。
臨床試驗顯示這些藥物在治療子宮內膜炎方面缺乏有效性的證據。由於受感染子宮腔內存在para-aminobenzoic acid代謝物，因此磺胺類藥物無效。
Penicillins很容易大量產生青黴素酶的細菌降解。
In consequence, several antibiotics are inappropriate. Nitrofurazone is irritant and has an adverse effect on fertility. Aminoglycosides are not effective in the predominantly anaerobic environment of the infected uterus. Field trials have also provided evidence for a lack of effectiveness of these drugs in the treatment of endometritis. Sulphonamides are ineffective because of the presence of para-aminobenzoic acid metabolites in the lumen of the infected uterus. Penicillins are susceptible to degradation by the large numbers of penicillinase-producing bacteria that are present.
