1.fFlukes – Chapter 10, All founda.Liveri.Fasciola hepatica1.“sheep liver fluke”2.Echinoa.Unembro3.Two suckers are same size4.Cephalic cone5.Operculated, yellowish eggs6.Gall bladder, bile duct, liver tissuea.Extensive liver damage by migrating juveniles7.Miracidium has 8 hours to find IH snail and penetrate it before it dies8.Egg > miracidium(environment) > sporocyst > redia 1 2 > cercaria >encyst as MC on watercress and other aquatic vegetation9.Worldwide --- South America, Caribbean, Algeria, S. France, G. B.a.Areas of sheep and cattle herding where in contact with feces10.Destruction of liver and bile duct tissue, hemorrhage, inflammatorydamage to tissues11.Juvenile worms can get lost in their migration, encyst in random areasand get calcified12.Initial: head/body aches, fever (cold like symptoms)13.Advanced: liver cirrhosis/growth, diarrhea and anemia14.Halzoun:consumption of infected cow liver (raw) in the Middle East15.Praziquantel sucks16.CT scan ELISA antibody testii.Clonorchis siensis
1.“Oriental Liver Fluke” ----- most common liver fluke in E. Asia2.Bile Duct3.Russia, China, Korea, Vietnam4.Opis = embro5.Small suckers6.Biliary systems of reptiles, birds, and mammals7.1stIH: snail2ndIH: freshwater fish8.Operculated, tanned eggs w/ knob9.Egg > snail > sporocyst > redia > cercaria > penetrate fish > MC encystin tissue10.Reservoir Hosts: cats, dogs, tigers, foxes, badgers, mink --- maintainparasite population11.Oriental ponds fertilized with human feces allows the cycle to continuea.A very rural infection12.Bile ducts are most damaged; liver isn’t harmed like F. hepatica due to alack of migration through it13.Damage is proportional to concentration of worms14.Extreme cases = liver growth, bile duct thickening, fibrosis, and somedamage to liver parenchyma; some intestinal distress is possible15.Rarely fatal unless immunocompromised (infected by other organismskills you)16.Eggs are similar to heterphyids17.Exam those who have liver enlargement and have been in endemic areas18.Look for recombinant C. sinensis proteins as antigens19. Praziquanteliii.Opishorchis felineus1.Bile ducts
2.South, central, eastern Europe, Turkey, S. Russia, Vietnam, India, Japan,Puerto Rico, Caribbean islands3.Diarrhea and thickening and erosion of bile duct wall4.Opis = embro5.1stIH = snail6.2ndIH = fish7.Stages similar to C. siensis8.Indistinguishable from C. siensis9.Catsare important reservoir hosts10.Eating raw fish gets the infectioniv.Opisthorchis viverrini1.Bile ducts2.Thailand, Laos, South East Asia3.Diarrhea and thickening and erosion of bile duct wall4.Opis = embro5.1stIH = snail6.2ndIH = fish7.Stages similar to C. siensis8.Indistinguishable from C. siensis9.Catsare important reservoir hosts10.Eating raw fish gets the infectionb.Intestinali.Fasciolopsis buski1.Largest digenean infecting humans2.Enchi = unembro
3.Ventral sucker larger than oral sucker; no cephalic cone4.Small intestine of pigs and humans NOT the liver5.Redia I and II6.
