i-cattle, equids, swine, rodents humans are susceptible zoonosis |
|
|
ID for Echinococcus multilocularis?
|
tapeworm 6 mm 4-5 segments
scolex with 4 suckers and 2 rows of hooks alveolar hydatid cyst occur in intermediate host in liver and other organs larval stage= alveolar hydatid cyst, exogenous budding.. as it grows (malignant neoplasm) eggs- taeniid type,brown 25-40 um radial striations 6 embryonic hooks |
|
|
life cycle for Echinococcus multilocularis?
|
indirect
liberate eggs which are passed in feces. intermediatehost ingests an egg. hexacanth larva penetrates intestine and migrates to LIVER. develops to alveolar hydratid cyst (second stage= infective!), then final host ingests intermediate host with cyst, scolices evaginate and attch to mucosa of SI and mature. PPP is 28 days |
|
|
site of infection for Echinococcus multilocularis?
|
adult in SI multilocular hydratid cysts in LIVER

NON- PATHOGENIC IN FINAL HOST
|
|

rare in final host. invasive growthin humans= fatal
|
|
|
diagnoisis for Echinococcus multilocularis?

remove all stray dogs do not feed offal |
|
|
hosts for Taenia crassiceps?
|
f- dogs, foxes
i-small rodents, carnivores, humans zoonosis |
|
|
ID for Taenia crassiceps?
|
adult cestode
4 suckers on scolex 2 m unilateral genital pores cysticerci in abdominal cavity of intermediate host (asexual budding) eggs- taeniid type, brown, radial striations |
|
|
life cycle for Taenia crassiceps?
|
gravid segments shed from carnivore final host thru anus. segments release eggs in environment--> oncospheres.
oncosphere ingested by intermediate host (small rodents), enter wall of SI. turns into cysticercus (infective to final host) final host ingests the cysticercus, develops in SI to adult (asexual budding) ppp 6-9 weeks |
|
|
site of infection for Taenia crassiceps?
|
adult tapeworm in SI
larval stages (cystecerci) in abdominal cavity of intermendiate host |
|
|
pathogenesis/ lesiosn for Taenia crassiceps?
|
infection in humans- eye (blindness), patients with impaired immune system
|
|
|
clinical signs for Taenia crassiceps?
|
infection in final host is usually asymptomatic
|
|
|
diagnosis for Taenia crassiceps?
|
eggs in fecal - flotation
|
|
|
treatment/ prevention for Taenia crassiceps?
|
cestocidal drugs, prevention of offal
|
|
|
host for Taenia pisiformis?
|
f- dogs, wolves, foxes
i- rabbits |
|
|
ID for Taenia pisiformis?
|
adult stages in final host, cysticerci for intermediate host
|
|
|
life cycle for Taenia pisiformis?
|
gravid segments shes from carnivore host. eggs in environment--> oncospheres. oncoshphere ingested by rabbit, enters wall of SI, migrates to liver and peritoneum. develops to 2nd stage cysticercus (infective to final host). final host ingests cysticercus, digested, develops in SI to adult worm. PPP 56 d

larval stage (strobilocercus) in liver of intermediate host eggs 25-40 um |
|
|
life cycle for Taenia taeniaeformis?
|
gravid segments shed from carnivore final host, release eggs in environment. develop to oncosphere. oncopshere ingested by mice/ rat, enters wall of SI and migrates to liver. develops to second stage (strobilocercus--infective). final host ingests strobilocercus in liver, digested, develops in SI to adult.
