Jejunal perforation caused by morphologically abnormal Taenia saginata saginata infection

We report a case of jejunal perforation caused by infection with taeniid tapeworm possessing unusual morphology that has not been previously described. Among five cestodes recovered during operation, one exhibited a bifurcation at the posterior end and the other harbored a lateral branching of immature segments from the main strobila. By sequence analysis of the mitochondrial cytochrome c oxidase I gene and the 28S rRNA gene has confirmed them to be Taenia saginata saginata.

Studies on Taenia saginata cysticercosis in eastern Nigeria

A total of 942 slaughtered cattle at Nsukka, Enugu, Abakaliki, Nkalagu and Onitsha slaughter houses were examined for evidence of Cysticercus bovis infection. 430 animals (45.65 per cent) were in the 2-4 year age group. 38 animals had cysticerci in their tissues. Out of the 38 infected cattle 26 (68.42 per cent) were in the 2-4 year group. Of these 26 cattle, 20 (76.92 per cent) had viable cysts in parts of their body while 6 (23.1 per cent) had dead cysts. 2 out of the infected 20 cattle had viable cysts in the liver but only one had viable cysts in the lung. The number of cysts found per carcase was between 1 and 5.23 (60.53 per cent) of the 38 infected carcases had single infection and 15 (39.47 per cent) had multiple infection. Most commonly infected parts were the heart, tongue, masseter muscle, diaphragm with its pillar, muscle of arm, muscle of thigh, liver, oesophagus and lung in that order. The prevalent rates for Nsukka, Enugu, Abakaliki, Nkalagu, Onitsha slaughter houses were 4.35 per cent, 3.2 per cent, 4.10 per cent, 7.5 per cent and 4.07 per cent respectively. Bovine cysticercosis infection in cattle can be controlled by environmental sanitation and through meat inspection done by well trained meat inspectors.     

Unusual colonoscopy finding： Taenia saginata proglottid

Infection with tapeworms is a major problem in many parts of the world. Patients may be asymptomatic or have a significant morbidity depending on the species. Infection with Taenia species is sometimes found by expulsion of eggs or proglottids in stool. Species specific diagnosis of Taenia is difficult, but possible. We present a case of Taenia saginata incidentally discovered, and risk factors for transmission, diagnosis, symptoms, and treatment.

Effectiveness of praziquantel against Taenia saginata infections in Ethiopia

Twenty-six individuals infected with Taenia saginata, 18 males and eight females ranging in age from 19-46 years, were treated successfully by a single oral dose of praziquantel at 10 mg kg-1 body weight. The drug was well tolerated, and no appreciable side effects were observed. Of the 26 patients, eight harboured one worm and the remainder harboured two or more worms; eight worms were obtained from one individual. In all 75 worms were recovered, ranging in length from 1.05-4.55 m, with a mean length of 2.26 +/- 0.36 m. The number of segments per worm ranged from 283-758, with a mean of 450 +/- 57.6. The mean wet and dry weights of the worms were found to be 26.1 +/- 2.7 g and 4.00 +/- 0.32 g respectively. The mean length of the worms, the mean number of segments per worm and the mean wet and dry weights were observed to decrease significantly (P less than 0.01) with an increase in the number of worms harboured by the patient.     

牛带绦虫可溶性抗原SDS-PAGE电泳初步分析

目的分析牛带绦虫可溶性抗原蛋白组分.方法用聚丙烯酰胺凝胶电泳(SDS-PAGE)对牛带绦虫成虫、牛囊尾蚴及牛带绦虫虫卵的可溶性抗原进行分析.结果牛带绦虫不同抗原的蛋白质区带主要分布于14～116kD之间.成节显示37条,主带14条(分子量分别为100,68,63,45,43,41,37,35,29,25,20,17,15,13kD);孕节显示35条,主带11条(分子量分别为68,63,45,43,35,29,25,20,17,15,13kD);虫卵显示9条,主带3条(分子量分别为68,38,25kD);囊尾蚴显示12条,主带6条(分子量分别为68,36,35,16,14,12kD).结论成虫的成节和孕节的蛋白图谱差别不大但与囊尾蚴的蛋白图谱有显著差别, 成虫和囊尾蚴的抗原可能有差别.     

Treatment with praziquantel the Taenia saginata infection in men

Praziquantel given in single doses of 12, 15 and 20 mg/kg body weight was applied in treatment of Taenia saginata infection (61 persons) and in four doses against Hymenolepis nana infection (1 person). Only one person not being cured shows that the compound has given a very high cure rate in clinical trial. 10% of patients treated complained of subjective mild side effects, which disappeared during 24 h after drug administration.     

都匀亚洲带绦虫和从江牛带绦虫实验感染小鼠免疫指标动态观察

目的 观察小鼠感染都匀亚洲带绦虫和从江牛带绦虫后血清免疫学指标的动态变化。方法 取新鲜都匀亚洲带绦虫和从江牛带绦虫孕节，分别用生理盐水洗净，置37℃水浴箱孵化成六钩蚴、经皮下或腹腔接种小鼠。分别于感染后40、60、75d取血作免疫学检查。结果 两实验组小鼠感染六钩蚴后血清免疫球蛋白均升高，其中IgM在感染后40d达高峰，之后开始下降；IgG、IgA在感染后60d达高峰，之后下降；补体C3、C4水平下降，至感染后75d，都匀亚洲带绦虫感染组和从江牛带绦虫感组分别下降82．8％和77．5％；检查两组小鼠血白细胞总数及分类，除嗜酸性粒细胞比例升高外其余无明显改变。结论免疫抑制小鼠感染都匀亚洲带绦虫和从江牛带绦虫后血清免疫学指标均发生显著改变，符合免疫应答规律。但从江牛带绦虫感染小鼠后，免疫学指标变化更明显。
