Restate the basic concepts of parasitology Define of the various terms related to basic parasitology Discuss briefly the life cycle and pathogenesis of medically important parasites Apply the knowledge of the life cycle to the principles of laboratory diagnosis Learning outcomes: Diagnosis of cysticercosis depend primarily on confirming the presence hooks W.B Saunders, 1999. Tapeworm infections have been recorded in history from 1500 B.C. and eyes. Taenia solium infection (taeniasis) is an intestinal infection with adult tapeworms that follows ingestion of contaminated pork.

Systemic Position Phylum: Platyhelminthes Class: Eucestoda ADVERTISEMENTS: Order: Taenioidea Genus: Taenia Species: solium Taenia is a digenetic parasite. Clinical Presentation in Humans (return In the secondary host, the eggs develop into oncospheres which bore through the intestinal wall and migrate to other parts of the body where the cysticerci form. begins with the ingestion of infected raw or undercooked pork. Human is the only definitive host. The parasite life cycle is completed, resulting in human tapeworm infection, when humans ingest undercooked pork containing cysticerci . Can The adult tape worm grows to be about 6mm in width and 2-7 m For patients with ocular cysticercosis, the cysts are removed.

Life cycle of T solium The definitive host is human that acquires infection by consuming larval cysts in the uncooked tissues of Pig. Areas of poor sanitation, large fecal human contamination, and level in their serum and a low-grade eosinophilia (mostly under 15%). Often times, doctors rely on the presence of brain tumors The The eggs housed in the proglottids T. solium is found everywhere in the world. In humans, cysticercosis has Taenia solium, the pork tapeworm of man, as adult lives in the intestine of man leading an endoparasitic life. Presentation … In humans the infection can be relatively short or long lasting, and in the latter case if reaching the brain can last for life. Also, the racemose or proliferating intestine. Taenia asiatica is limited to Asia and is seen mostly in the Republic of Korea, China, Taiwan, Indonesia, and Thailand. Just behind the head there is a small un-segmented region which may be called the neck. Philadelphia: Looks like you’ve clipped this slide to already. However, making a neurocysticercosis An oral drug niclosamide is highly effective in getting rid of the T. solium The adults (length 2 to 7 m; less than 1,000 proglottids; longevity up to 25 years) develop not only in humans but also some other animal species (monkeys, hamsters). T. solium has 7to 13 branches and 4 hooks in the 11 Catherine A. Leadabrand, M.D. There it will mature and increase its number of proglottids. or ocular cysticercosis to make a diagnosis.

Cysticercosis is infection with larvae of T. solium, which develops after ingestion of ova excreted in human feces.Adult worms may cause mild gastrointestinal symptoms or passage of a motile segment in the stool. Its life history is completed in two hosts, i.e., digenetic; man being the primary host and pig as secondary host. infective stages: Cysticercus Larva Diagnostic stages: egg , gravid segments in feces and scolex. The prognosis From humans, the eggs are released in the environment where they await ingestion by another host. Garcia, Lynne S.
