《每周一问》活动目的有二，其一是为了让大家更好的学习和交流，其二是增加获得奖励的机会。每周一专家发帖提问，同周五专家公布答案。期间答对问题的用户将获得奖励，奖励多少由专家视情况而定，期待你的参与~~


外耳炎可由多种微生物引起，其临床表现不同。测试你的外耳炎知识。


1：Clinical signs of otitis externa may include which of the following?
1：外耳炎临床症状可能包括？
A：Head shyness低头（头部不适）
B：Head shaking甩头
C：Odor异味
D：All of the above以上症状都有

The correct answer is D. Clinical symptoms of otitis externa may include significant ear itching and head shaking, self trauma and matted hair behind the pinnae from excessive scratching, an aural hematoma, dried or crusty exudate at the ear canal opening, severe pain and head shyness, and neurologic signs (eg, facial nerve palsy, Horner syndrome, head tilt, nystagmus).正确的答案是D。外耳炎的临床症状可能包括明显的耳部瘙痒和甩头、自我损伤和耳廓后因过度抓挠而产生的脱毛、耳血肿，耳道口干燥或坚硬的渗出物，严重的疼痛和低头（头部不适），以及神经症状(如面神经麻痹，霍纳综合征，头倾斜，眼球震颤)。

2：True or false? Ear cytology is not helpful for determining the best treatment protocol.
2：耳细胞学检查对确定最佳治疗方案没有帮助。对 或 错？
A：True
B：False

False. Characterizing the relative numbers and types of microorganisms, if present, helps the veterinarian choose the best treatment. Otic cytology identifies bacterial and/or yeast infection and ceruminous problems, and neutrophils, if present, give a prognostic indicator.
错。描述耳道内微生物的相对数量和类型，如果存在，有助于兽医选择最好的治疗。耳道细胞学检查可鉴别细菌和/或酵母菌感染和耵聍问题，如果存在中性粒细胞，可作为预后指标。


3：True or false? Ceruminolytic ear cleaners can be used to clean waxy debris even if the eardrum cannot be visualized.
3：即使看不到鼓膜，也可使用耵聍溶解剂洗耳液清洗耳垢碎片。对 或 错？
A：True
B：False


False. If the eardrum is intact and the ear canal is waxy,  cerumenolytic cleaners can be used. However, if the ear drum  is not intact or cannot be visualized, ceruminolytic cleaners  should not be used because ototoxic ear-cleaning chemicals  can enter the middle and inner ears. Some chemicals are  proinflammatory to the mucous membrane that line the  tympanic bulla, creating more purulent material and mucus.
假的。如果鼓膜完好，耳道光滑，可使用耵聍溶解剂。然而，如果鼓膜不完整或无法看到，则不应使用耵聍溶解剂。
因为耳毒性清洁剂可能进入中耳和内耳。有些化学物质对鼓室大泡粘膜有促炎作用，产生更多的化脓性物质和粘液。

4：Malassezia spp exudate generally appears in which color?
4：马拉色菌属的分泌物通常表现什么颜色?
A：Yellow
B：Green
C：Brown
D：Clear

The correct answer is C. Malassezia spp likely exists when the [size=12.8138pt]exudate is pale brown with moderate wax.
正确答案是C.马拉色菌属存在时，分泌物是淡棕色，中等程度耳垢。

The correct answer is C. Malassezia spp likely exists when the
exudate is pale brown with moderate wax
5：An ear infection with gram-negative rods often yields exudate of which color?
5:革兰氏阴性杆菌导致的耳部感染通常产生什么颜色的分泌物?
A：Yellow
B：Green
C：Brown
D：Red



The correct answer is B. Green mucoid exudate and purulent [size=12.8138pt]hemorrhage are normally seen with gram-negative rods (ie,[size=12.8138pt]Pseudomonas [size=12.8138pt]spp,[size=12.8138pt] E coli[size=12.8138pt], [size=12.8138pt]Proteus [size=12.8138pt]spp).
绿色粘液样渗出和化脓性出血通常见于革兰氏阴性杆菌(即假单胞菌、大肠杆菌、变形杆菌)。
