by using EITB rT24, ranging from 6 (2.
In the CNS, the cysticerci
(the larvae) may lodge in the brain parenchyma, the spinal cord, the sub-arachnoid space, or the ventricles, lying dormant for years or causing various categories of clinical disease (Table 2).
have a propensity for developing in the central nervous system (60% of cases) (4) and are classically described as containing an invaginated scolex (head of organism).
The four patients had recurrent seizures, and the brain lesions identified by diagnostic imaging were consistent with cysticerci
This infection is acquired via ingestion of cysticerci
, the larvae of the Taenia solium (tapeworm, or cestode), in uncooked/undercooked pork or fecally contaminated food or water.
Gastrointestinal tapeworm infections result from the ingestion of cysticerci
in undercooked meat.
Usually both 'healthy' (active) and 'involuted' (inactive) cysticerci
lack inflammatory response, which is restricted to 'currently degenerating' cysts whose ability to evade host defences is becoming faulty.
1 Whereas parenchymal cysticerci
can be readily identified on CT and MRI, most authors agree that it is difficult to identify lesions within the cerebrospinal fluid (CSF) spaces.
In 1974, Herbert found that the immune system might participate in removal of cysticerci
from the host.
This paper includes data on 2004, and covers a wide range of diseases and pathogens, including salmonella, campylobacter, listeria, VTEC, mycobacteria, brucellosis, yersinia, trichinella, echinococcus, toxoplasma, cysticerci
sarcocystis, rabies and e-coli.
Once inside the brain, the primary larvae develop into secondary larvae, the cysticerci
are located in the central nervous system, the disease is known as neurocysticercosis (NCC).
