- Taenia serialis
70 micrometer size of an egg is?
M
In Pseudopyillidea, what stage comes before the adult?
plerocercoid
How is the stage inside arthropods in Cyclophyllidea called?
cystocercoid
diagnosis method of fasciolosis
- clinical signs and history
- serological: GLDH ,GGT,ALT,AST
- ELISA
- faeces examination
- passive haemoglutination test ( finding Ab)
pathogenesis of f.hepatica:
vary according the phase-
1st phase: during migration in liver parenchyma: liver damage and hemorrhage
2nd phase: occur when the parasite in the bile duct result from haemotophagic activity of adult flukes and from damage to biliary mucosa by the cuticular spines
chronic ovine fascilosis:
most common form of disease occure 4-5 month after ingestion of 200-500 metacercaria anemia hypoalbumionemia fibrosis loss of condition ascites.
fasciola and dicrocelium comparison:
(update with pic when pro)
Dicrocelium - 2 IH, no redia, embryonated, 2 sporocyst, no parenchymal migration and more…
fascilosis buski
s.i. in man and pig
LC of fasciola magna:
deer and other Ru. same as f. hepatica
eurytema panceaticum FH , IH:
(family: dicrocelidae)
FH: Ru IH: 1.land snails (eggs,sporocystX2 ,cercaria) 2.grasshopper and tree crickets (cercaria ,metacercaria) ( in the pancreatic duct)
pathogenesis and clinical signs: (paraphistomum?)
pathogenesis: intestinal phase : young flukes plug feeders and this result in severe erosion in the duodenal mucosa in heavy infection : enteritis, oedema, hemorrhages and ulceration clinical signs: diarrhoea .anorexia, intense thirst ( can be 90% mortality in cattle), rectal haemorrhages following a period of prolonged straining. Most common: cervi, microbothrium. No use in faecal examination they break in the prepatent period.
metagonimus in which animals:
fh: fish-eating mammals ih: 1) Water snail
2) fish
in which control cannot be achieved by fencing water areas around pasture:
dicrocelium ( not water snails)
schisostoma site: (in all mammals)
furcocercaria penetrates skin and causes dermatitis, then migrate to mesenteric arteries and the hepatic portal vein. Further migration according to species
S. mansoni - hepatic
S. japonicum - s.i veins
S. haematobium- urinary bladder
pathogenesis of schisostoma
in sheep much serious in acute disease- diarrhoea ,anorexia ,death, hemorrhagic lesions in intestine mucosa, anemia, hypoalbuminemia, emaciation.
prostagonimus host:
poultry
prostagonimus IH and site:
IH -water snail Dragonflies (nymph stage) Site: bursa fabricus In galinaeceous birds- in the oviduct -this is the pathogenic!!!
