the scolex, were considered as living cysticerci
. Lesions were interpreted as calcified cysticerci
when presented with a fibrous capsule adhered to the surrounding tissue containing a whitish to yellowish material, with a caseous and/or calcareous appearance.
All hepatic lesions and cysticerci
in the peritoneal cavity were counted at necropsy, and hepatic samples of lesions detected were recovered, fixed in 10% buffered formalin and processed for histological analysis.

: Clinical manifestations, natural history, and treatment," Pathogens and Global Health, vol.
follows a ping-pong bi bi kinetic mechanism with the NADPH/GSSG couple as the substrates, in which dissociation of [NADP.sup.+] from the enzyme during the catalytic cycle is an irreversible event.
solium commonly forms cysticerci
in tissues of various atypical intermediate hosts, including rabbits, camels, dogs, cats, and humans (2,4).
There are few reports of accidental ingestion of eggs and the subsequent development of the cysticerci
in the central nervous system in nonhuman primates which may cause neurological signs and lesions similar to those in humans.
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).
Steroid hormone production by parasites: the case of Taenia crassiceps and Taenia solium cysticerci
Subsequent penetration of the mucosa by the embryos results in cysticerci
developing in the human organs and tissues.
The ova develop into larvae, penetrate the intestinal wall, disseminate throughout the body via the vascular system, and encyst in tissue as cysticerci
. (1) Cysticerci
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
. Timely diagnosis could lead to treatment.
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.
