cercariae

These organisms penetrate into snails, multiply, and develop into cercariae , the infective form for man.

这些毛蚴进体螺体, 繁殖和发育对人类有传染性的尾蚴.

The tegument morphology of cercariae and adult of Sanguinicola lungensis was studied under Scanning Electronic Microscope.

用扫描电镜观察了龙江血居吸虫尾蚴及成虫体表的超微结构.

The pictures of miracidia were recorded after co-cultivation for 1 h, 12 h, 24 h and 3 d. The co-cultivated for 3 days mother sporocysts injected in the head and foot of negative snails, after 80 days, observed whether cercariae could be obtained or not.

分别拍摄共培养1h、12h、24h及3d毛蚴生长照片。将培养3d的母胞蚴注射于阴性钉螺头足部，80d后观察钉螺逸蚴情况。

schistosoma including the life history of adult, egg, miracidium, sporocyst , cercariae and insects, such as children 6 stage.

血吸虫的生活史包括成虫、卵、毛蚴、胞蚴、尾蚴及童虫等6个阶段。

clonorchis cercariae were supplied by the department of parasitology of sun yat-sen university.

华支睾吸虫尾蚴由中山大学中山医学院寄生虫学教研室提供。

Effective resistance against 5. japonicum was induced by prior exposure to ultraviolet-attenuated cercariae of S. japonicum with 400 μ W/ ( min · cm2) on mice in single time.

以400μW/（min·cm~2）剂量紫外线照射减毒日本血吸虫尾蚴，1次免疫小鼠（200条/只）可产生抗日本血吸虫感染的免疫能力。

Methods 9 water buffalos aged 8-10 months were selected from non-endemic area. Each water buffalo was challenged with 2000 Schistosoma japonica cercariae.

方法选择购自血吸虫病非流行区8～10月龄水牛9头，每头水牛感染血吸虫尾蚴2000条。

From an investigation conducted in the four natural villages in Yunnan mountainous regions, the results showed that 1. the frequency of the water-contact with cercariae in familial and public places and the labor exchange in women were significantly higher than those in men.

通过云南省四个山区自然村的调查显示：女性的换工及家庭范围内易感环境接触疫水频率均非常显著高于男性。

To observe the tegumental ultrastructure of egg, cercariae and the adults of Echinostoma Miyagawai may provide information for its taxonomic studies and its biological characteristic.

目的观察宫川棘口吸虫虫卵、尾蚴及成虫的体被超微结构，为其分类及其生物学特性的进一步认识提供资料。

Consecutive detections on CAb, CAg and CIC levels of sera were carried out from 2 to 18 weeks after rabbits exposed to Schistosoma japonicum infection. Rabbits were divided into four groups and each group was infected with 10 or 50, unisexual or bisexual cercariae respectively.

本文对感染10条与50条单、双性血吸虫的4组家兔，在感染后2&18wk，连续检测了血吸虫CAb、CAg及CIC水平，并与正常对照兔进行了对比。

the nipples having cilium , sanken having or not cilium and little holes are distributed symmetrically around the oral sucker of cercariae.

尾蚴的口吸盘周围对称分布着有纤毛的乳突，有或无纤毛的凹陷及小孔；

the positive rate of encysted metacercaria in p. striatulus was 6.67% ( 8/ 120), and the positive rate of rediae and cercariae in p. parva was 0.60% ( 6/ 1000).

麦穗鱼中囊蚴检出率为6.67%（8/120）。纹绍螺体内雷蚴和尾蚴阳性率为0.60%（6/1000）。

The frequency of water-contact with cercariae in public places and the labor exchange in the group with low income was significantly higher than those in the group with high income, respectively.

经济收入高者换工频率低，接触疫水的频率显著高于经济收入低的人群。

CONCLUSION: Various test/ probe systems have different efficacy in detecting SCA but ( 5) of the methods ( 1)( 2) tests/ probe systems could not detect SCA in rabbits with single female cercariae infection.

结论：不同的试验／探针系统的检测效果不同，但所试3种方法（1，2，5种）都不能检出单雌性感染。

CONCLUSION: It is suggested that STRP can enhance the humoral response of mouse to SWA and elicit stronger resistance to schistosome cercariae challenge infection.

结论：STRP可以增强小鼠对血吸虫抗原的体液免疫应答反应，并且可诱导小鼠产生较强的抗尾蚴攻击感染能力。
