A:Leishmania Donovani B:Entamoeba histolytica C:Giardia Lamblia D:Plasmodium vivax
AI参考:正确答案是A:Leishmania Donovani。Kala-azar即黑热病,是由利什曼原虫中的杜氏利什曼原虫(Leishmania Donovani)引起的疾病。其他选项中,Entamoeba histolytica是溶组织内阿米巴,Giardia Lamblia是小肠阿米巴病,Plasmodium vivax是疟疾。因此,答案是A。'
A:Liver B:intestinal mucosa C:Lung D:Heart
答案:mature cystAI参考:The trophozoite of Giardia Lamblia has a concave sucking disc, which helps in its attachment to the intestinal mucosa.答案:B。解释:Giardia是一种寄生虫,其滋养体(trophozoite)具有一个凹陷的吸盘(sucking disc),这个吸盘有助于它附着在肠粘膜(intestinal mucosa)上。因此,选项B是正确的。其他选项A(肝脏)、C(肺)和D(心脏)都不是滋养体与人体组织的正确对应关系。'
A:2 B:3 C:4 D:1
答案:Superior mesenteric vein
A:Eggs B:Cercariae C:Cysticercus D:Miracidium
答案:um
A:Paromomycin B:Tinidazole C:Metronidazole D:Furazolidone
答案:PropranololAI参考:正确答案是C:Metronidazole(甲硝唑)。Metronidazole(甲硝唑)是一种治疗毛滴虫感染的药物,可用于治疗孕妇感染的贾第鞭毛虫病。Paromomycin(链霉素)、Tinidazole(替硝唑)和Furazolidone(呋喃唑酮)通常用于治疗其他类型的感染,如细菌感染或阿米巴病,不应用于治疗孕妇感染的贾第鞭毛虫病。因此,答案为C。'
A:day B:morning C:night D:afternoon
AI参考:正确答案是C:night。题干中提到Pinworm的卵在晚上大量沉积在肛门和会阴皮肤上,因此答案为C。其他选项A、B、D都不符合题意。'
A:Pseudocyst B:Oocyst C:Tachyzoites D:Bradyzoites
答案:all of the above
A:Plasmodium vivax B:Toxoplasma gondii C:Giardia Lamblia D:Entamoeba histolytica
AI参考:正确答案是B:Toxoplasma gondii。Toxoplasma gondii是一种常见的寄生虫,可以引起旅行者腹泻,因此选项B是正确答案。其他选项中,Plasmodium vivax是疟原虫,Giardia Lamblia是小肠阿米巴病,Entamoeba histolytica是溶组织阿米巴病,这些疾病通常不会引起旅行者腹泻。'
A:Definitive host B:Transport host C:Intermediate host D:Reservoir host
A:Culture B:Demonstration of amastigotes in smears of tissue aspirates C:ELISA D:animal inoculation methods
A:Giardia Lamblia B:Entamoeba histolytica C:Plasmodium vivax D:Toxoplasma gondii
AI参考:正确答案是B:Entamoeba histolytica。Entamoeba histolytica是一种单细胞生物,能够引起肝脏脓肿,是引起人类阿米巴肝脓肿的病原体。其他选项中,Giardia Lamblia(A)是一种能够引起腹泻的寄生虫,Plasmodium vivax(C)是疟原虫的一种,而Toxoplasma gondii(D)是弓形虫,主要通过猫传染给人类。因此,B选项是正确答案。'
A:Giardia Lamblia B:Plasmodium vivax C:Trichomonas vaginalis D:Entamoeba histolytica
AI参考:正确答案是D:Entamoeba histolytica。原生物中的溶组织内阿米巴属是肝脏细胞中的寄生虫,也就是选项D Entamoeba histolytica。其他的选项如 Giardia Lamblia 和 Plasmodium vivax 都是原生物中引起其他症状的寄生虫,Trichomonas vaginalis 是一种引起性病的原生物。因此,答案是D。'
A:The eggs develop in water B:The adult worms parasite in small intestine C:The eggs develop in soil D:The larvae develop in human’s body
AI参考:A错误。选项A中提到,钩虫卵在水中发育,而实际上钩虫卵需要在湿润、肥沃的土壤中发育成幼虫。因此,选项A描述是不正确的。选项B、C和D都是正确的描述,分别涉及钩虫的寄生部位和发育阶段。因此,正确答案是A。'
A:Raise B:lower C:unchanged D:Unidentified
AI参考:选项B:lower,是正确答案。Trichomonas Vaginalis是一种常见的阴道寄生虫,它会改变阴道液体的pH值。具体来说,它会降低阴道液体的pH值,使其变得更加酸性。因此,答案为B:lower。'
A:the mucosal cells of intestine B:red blood cells C:macrophage D:Lung cells
A:Dog B:Cat C:Cow D:Man
A:lung cell B:liver cell C:Spleen cell D:Red cell
A:1 B:3 C:2 D:Unidentified
AI参考:正确答案是C,2个。根据题干中的描述,圆虫涉及(涉及到的)宿主有两个,因此选项C“2”是正确答案。选项A“1”、B“3”和D“Unidentified”都不符合题干中的描述。'
A:urine B:blood C:Sputum D:Stool
AI参考:答案:B:Blood。疟疾的诊断是通过检测血液中的疟原虫来确认的。尿液、痰液、粪便等都不是诊断疟疾的可靠方法。因此,答案为B。'
A:2 B:3 C:4 D:1
A:Undiagnostic stage B:Uninfective stage C:Diagnostic stage D:Infective stage
AI参考:正确答案是D:Infective stage。题目中描述的是“蛔虫卵通过粪便排出”,这是感染阶段,因此选项D“Infective stage”是正确答案。选项A“Undiagnostic stage”意为“未诊断阶段”,与题目描述不符;选项B“Uninfective stage”意为“无感染阶段”,也与题目描述不符;选项C“Diagnostic stage”意为“诊断阶段”,虽然与题目描述有一定关联,但题目中并未提及诊断过程,因此也不符合题目要求。'
A:Trophozoite B:Oocyst C:Cyst D:Both trophozoite and cyst
A:Paromomycin B:Tinidazole C:Metronidazole D:a pentavalent antimonial compound.
A:an infected male anopheles mosquito B:an infected male sandfly C:an infected female anopheles mosquito D:an infected female sandfly
A:对 B:错
AI参考:答案:B:错。问题中明确提到“随着疟疾的进展”,所以这个病人可能会表现出脾脏和/或肝脏的增大以及贫血。因此,这句话的描述是错误的。综上,此题应选择B:错。'
A:错 B:对
A:对 B:错
A:错 B:对
A:错 B:对
A:错 B:对
AI参考:B.对。Amastigote form of Leishmania Donovani是利什曼原虫在沙蝇体内的发育阶段,同时也存在于人工培养基中。因此,这个说法是正确的。'
A:对 B:错
AI参考:答案:B:错。题目中提到牛肉绦虫的包囊可以感染人类,但是实际上包囊本身并不会直接感染人类,只有在包囊成熟并释出的幼虫进入人体后才会导致感染。因此,该题描述是错误的。'
A:对 B:错
A:对 B:错
AI参考:答案:B:错。Trichomonas vaginalis是一种性传播疾病,但是它也可以通过间接接触传播,如使用共用浴巾、浴盆等。因此,单纯的性传播并不是其主要的感染途径。所以,这个判断题是错误的。'
A:错 B:对
A:Food and drinks must be protected from flies and cockroach. B:Drinking water must be boiled . C:Fresh human feces should not be used as fertilizer. D:Pay attention to personal hygiene
AI参考:正确选项为B:饮用水的处理方式是煮沸。预防阿米巴痢疾的方法主要是切断传播途径,其中饮用水的处理方式是非常重要的一环。煮沸是常用的饮用水处理方法,可以有效杀灭水中的病原体,从而预防阿米巴痢疾的发生。其他选项中,保护食物和饮料免受苍蝇和蟑螂的污染、避免使用新鲜人类粪便作为肥料以及注意个人卫生等措施虽然也是重要的预防措施,但并不能直接预防阿米巴痢疾。因此,选项B是正确的选择。'
A:the timely use of malaria testing and treatment B:the routine use of insecticide-treated bed nets C:Do not drink contaminated water D:indoor spraying with insecticides
AI参考:正确选项为:B:the routine use of insecticide-treated bed nets。世界卫生组织推荐的预防疟疾的措施包括:定期使用驱虫蚊帐(B对),这是最有效的预防措施之一;不喝污染的水(C对),但这不是专门针对疟疾的预防措施;及时治疗和检测疟疾(A对),但这并不是预防措施,而是治疗措施;室内喷洒杀虫剂(D错)通常用于控制疟疾的传播,但并不是专门针对疟疾的预防措施。所以答案是B、C、D都可以入选,但是根据选项完整度,只应该选择B选项。'
A:female sandfly B:Mosquito C:man, or some other mammal D:Fish
AI参考:正确选项为A:female sandfly莱氏耶氏线虫(L. donovani)的生命周期需要雌性沙蝇作为其宿主。选项B中的蚊子并不是必需的,选项C中的哺乳动物或其他动物也不是必需的,选项D中的鱼类也并不是其生命周期中必需的宿主。因此,只有选项A是正确的。'
A:Cyst B:amastigote form C:promastigote form D:Trophozoite
AI参考:正确选项是【B:amastigote form】。莱氏滴虫存在的一种形式是amastigote形式,这是一种在寄生虫体内进行生命活动的形式。而选项A的cyst(囊肿)通常指的是某些生物体在特定环境下的封闭结构,与莱氏滴虫无关;选项C的promastigote(鞭毛虫形式)是疟原虫的一种存在形式,与Leishmania Donovani无关;选项D的trophozoite(滋养体)是某些寄生虫在寄主体内进行生命活动的一种形式,但并非Leishmania Donovani的特定存在形式。因此,B选项amastigote form是正确答案。'
AI参考:选项C,使用抗滴虫药物是防止感染阴道滴虫的有效方法。其他选项可能也有效果,但在这个问题中没有详细说明。所以,正确答案是C,使用抗滴虫药物。预防感染阴道滴虫的方法包括保持清洁卫生、避免不洁性行为、使用避孕套等,但最有效的方法是使用抗滴虫药物。这类药物通常由医生开具,并根据感染程度和个体情况来决定使用剂量和频率。在使用抗滴虫药物时,需要遵循医生的建议,并按照药物说明书进行操作。同时,在治疗期间避免性行为,以减少感染的风险。'
A:epigastric pain B:Fever C:tender hepatomegaly D:Diarrhea
A:Proper disposal of waste water and feces B:Community chlorination of water is not effective for Giadia when in the cyst stage, and boiling of water and filtration by membrane filters are required. C:Practice of personal hygiene like hand-washing before eating and proper disposal of diapers D:Prevention of food and water contamination
AI参考:正确选项是:A:Proper disposal of waste water and feces C:Practice of personal hygiene like hand-washing before eating and proper disposal of diapers。预防贾第虫病的方法包括:正确处理污水和粪便;个人卫生,如饭前洗手,并妥善处理尿布;对于囊包虫阶段的水,社区氯化效果不显著,需要煮沸或膜过滤来净化水。因此,选项A和C是正确的。选项B提到的是净化水的方法,但是针对的是囊包虫阶段的水,不适用于预防贾第虫病;选项D提到的是防止食物和水污染,但并非专门针对预防贾第虫病的方法。'
A:Cow B:Mosquito C:Human D:sandfly
AI参考:正确选项为:C:Human。疟原虫(Plasmodium)是一种寄生虫,其中恶性疟原虫(Plasmodium falciparum)是一种对人危害较大的疟原虫。它主要寄生在人体的红细胞内,因此人类是恶性疟原虫的宿主。其他选项中,cow(牛)、mosquito(蚊子)和sandfly(沙蝇)都不是疟原虫的宿主。因此,答案为C选项,即人类。'
