11. Discussion
Introduction:
 Disease of the central nervous system of
ruminants ,horses, pigs and humans
 caused by Coenurus cerebralis, the
larvalstage of the (Taenia multiceps )
 Tapeworm inhabits the small intestine of
the definitive hosts like dogs and wild
canids, such as foxes, jackals and
coyotes
Soulsby 1982
11

12. Etiology
 Coenurus cerebralis (coenurus cyst)
larval stage/ metacestode of T.multiceps
Cyst measures 0.5–5cm in diameter
- Translucent walls: containing large
fluid with several hundred protoscolices
- Lying free on the leptomeninges or
partly penetrating the brain tissue and spinal
cord (primary site)
-may present in intramuscular and
subcutaneous tissues
12

13. Host related facts
 Adult stage of parasite is harbored by
canine species in the GIT (they acts as
definitive hosts)
 Larval stage is found in small
ruminants(most commonly in sheep CNS
and IM/SC in goats)
 Other species like bovine, equine, swine
and human may be infected with the
metacestode of parasite

15. Risk factors
 Contamination level of environment
 Dispersion of eggs
 Eggs survival
 Age of host
 Immune response of host
 Heterologous infection

16. Pathogenesis and clinical signs
Ingestion of
contaminated
pasture
large number of
immature stages
migrate in the brain
an acute
meningoencephalitis
Chronic Infection is
seen in1-6 months
by increase in
coenurus size and
destruction of brain
tissue
16

17. The cyst is
situated in
peripheral
region in one
of cerebral
hemisphere
Animal holds
its head to
one side and
turns in circle
towards the
affected side
Blind in the
eye opposite
to the side of
infection

18. cont..
Parasite in the
anterior part
Head is held against
chest and animal
steps high or may
walk in a straight line
till it meets obstacle
and remain
motionless

19. Cont..
Invasion of
cerebellum:
hyperesthesia
,jerky or
staggers
movements
and may
prostration
In spinal
cord:
progressive
paresis of
one or both
limbs
On the
surface of
brain :
atrophied or
perforated
skull bone

21. Diagnosis
 Diagnosis by specific serological test is
not available
 An early diagnosis prior to clinical sign
development is done by ophthalmoscopy
of eye
 Perforated part can localize by painful
manipulation or for accurate localization
radiography is suggested
21

22. Treatments
 In many cases Rx is useless
 If cyst is present in the brain : surgical
removal is possible after general
anaesthesia and recovery is good
especially if localization of cyst is
accurate
 Combination of the praziquental and
fenbendazole may helpful
 It is found that many farmers may
choose to slaughter those fit for
marketing for economic reasons and
euthanise those in poor condition.
22

23. Control
 Use of tenicidal drug for all farm dogs to
break life cycle of parasite
 Carcass of animal infected with cyst
should be disposed safely and should not
be available to dogs
23

24. Conclusion
 Since, the critical clinical stage the
disease is incurable
 But the disease can be controlled by the
alteration of pasture
 Effective deworming of both definitive and
intermediate hosts of parasite
