Dipylidium caninum is a common intestinal tapeworm of dogs, cats and foxes. However, it occasionally infects also humans. We present a case of D. caninum infection in a 2-year-old child living in the Subcarpathian province. The infection was asymptomatic in the first months. The symptoms of abdominal pains, sleep disorders, loss of appetite, hyperactivity and occasional slimy stools appeared later. Proglottids on the underwear, in water while bathing and mobile proglottids passed with the stool were also observed. Prior to appropriate diagnosis the child was treated with pyrantelum (Pyrantelum) and albendazolum (Zentel). However, proglottids were found again in the stool after a few days. We examined stool samples and perianal smears collected from the child and his family. The stool samples were tested by coproscopic methods. Direct methods (direct preparation in 0.9% sodium chloride and in Lugol's solution, Kato thick smear) and concentration methods (decantation with distilled water and Faust's zinc sulphate centrifugal flotation) were used. In the stool samples taken from the child, we observed D. caninum proglottids demonstrating lateral genital pores and many packets of eggs containing from one to a few, mostly 3 to 4 eggs. In the direct preparations in 0.9% sodium chloride and in Lugol's solution single packets with D. caninum eggs were detected. In decantation preparations many D. caninum egg packets were observed. It has to be reported that the child's mother was infected with Giardia intestinalis. Dipylidiasis in humans is a rarely encountered infection in Poland and the diagnosis may be difficult. For these reasons we reported clinical case presentation, diagnostics, treatment and epidemiology of D. caninum infection. We have shown that concentration methods such as decantation might be very helpful in the diagnosis of dipylidiasis.
犬复孔绦虫是犬、猫和狐狸常见的肠道绦虫。然而,它偶尔也会感染人类。我们报告一例生活在喀尔巴阡山省的2岁儿童感染犬复孔绦虫的病例。最初几个月感染无症状。后来出现腹痛、睡眠障碍、食欲不振、多动以及偶尔的黏液便症状。还观察到内裤上、洗澡水中有孕节,粪便中排出可活动的孕节。在做出正确诊断之前,该儿童接受了噻嘧啶(驱虫灵)和阿苯达唑(肠虫清)治疗。然而,几天后粪便中又发现了孕节。我们检查了从该儿童及其家人采集的粪便样本和肛周涂片。粪便样本采用粪便检查方法检测。使用了直接方法(在0.9%氯化钠溶液和卢戈氏溶液中直接制片、加藤厚涂片)和浓缩方法(蒸馏水倾析法和福斯特硫酸锌离心浮聚法)。在从该儿童采集的粪便样本中,我们观察到犬复孔绦虫孕节,显示出侧生殖孔以及许多含1至少数个、大多为3至4个虫卵的虫卵包。在0.9%氯化钠溶液和卢戈氏溶液直接制片中检测到单个含犬复孔绦虫卵的虫卵包。在倾析制片中观察到许多犬复孔绦虫卵包。必须报告的是,该儿童的母亲感染了肠道贾第虫。在波兰,人类感染犬复孔绦虫病很少见,诊断可能困难。出于这些原因,我们报告了犬复孔绦虫感染的临床病例表现、诊断、治疗和流行病学情况。我们已经表明,诸如倾析法等浓缩方法在犬复孔绦虫病的诊断中可能非常有用。
