Introduction
Fasciolopsis buski（布氏姜片吸虫） is prevalent
（流行的） in Southeast Asia and living in the
small intestine（小肠） of humans and pigs, so it is
also called Asia Giant Intestinal Fluke. The
prevalence of
fasciolopsiasis（布氏姜片吸虫病）
is related to growing water plants and feeding pigs
on water plants.
Morphology（病原形态）
1. Adult: the body is long elliptic（椭圆形的）,
flesh-colored, looks like a slice of raw meat. The size
is about 20~75× 8~20 ×0.5~3mm, the largest one of
human trematodes（吸虫）. The ventral sucker
（腹吸盘） is nearby the much smaller oral sucker
（口吸盘）. Two coral-liked testes are located in the
posterior half of the body.
Oral
sucker
acetabulum
2. Egg: it is oval in shape, slight
yellow in color, The size is about
130~145×85~97µm(the
largest
helminth（寄生虫） egg. The thin
shell（卵壳） with an operculum
（卵盖） encloses an ootid（卵细
胞） and 30~50 yolk cells（卵黄细
胞）.
Epidemiology （流行病学）

This disease occurs in Asia and the
Indian subcontinent, especially in
areas where humans raise pigs and
consume raw aquatic plants（水生
植物）.
Life cycle（生活史）
1. Site of inhabitation（寄生部位）: small intestine
2. Infective stage: metacercaria（囊蚴）
3.
Infective
mode:
eating
raw
water
plants
with
metacercariae
4. Medium of water plants: chestnut, water bamboo and
caltrop
5. Intermediate host（中间宿主）: segmentina（扁卷螺）
6. Reservoir host（保虫宿主）: pig
7. Life span: 1-4 years
Symptoms（症状）

Most infections are light and
asymptomatic（无症状的）.

In heavier infections, symptoms include
diarrhea（下痢）, abdominal pain（腹
痛）, fever, ascites（腹水）, anasarca
（全身水肿）, and intestinal obstruction
（肠梗阻）.
Diagnosis（诊断）
Stool examination（粪检）:
1. Direct fecal smear（直接涂片
法）
2. Water sedimentation method
（沉淀法）
Treatment and Prevention（防治）
1. Treatment
（1）Dipterex（敌百虫）
（2）Bitin（别丁）
（3）Praziquantel（吡喹酮）
（4）Amosconate (硝硫氰胺）
（5）Nitroscanate (硝硫氰醚）
2. Comprehensive Prevention
(1) Health education
(2) Feces management（粪便处理)
(3) Periodic deworming（定期驱虫）
(4) Snail control
(5)Management of pig husbanandry:
avoid feeding pigs on raw water plants
